Homemade pump. DIY hand pump for water in different versions. Building a water pump yourself

When moving from a city to a village, you are faced with the issue of watering the garden and water supply to the house. The one who used it without interruption submersible pumps, knows perfectly well how reliable the various “Streams”, “Springs”, “Gnomes” are. Most vibration devices do not last even one season active work, often breaking down within a month after purchase. But you want to drink every day, and you also need to water the garden, so it is advisable to have a spare pump in case of an accident. Of course, you can keep in stock a repaired water pump that previously failed and had to find a replacement. It is also quite possible to make a water pumping unit with your own hands.

In order to assemble a homemade water pump you will need:

1. small Electrical engine, power up to a maximum of 1.5 kW;
2. electrical cable or extension cord;
3. water pump or oil pump;
4. transmission system in the form of a belt and pulleys or pins and coupling halves;
5. rubber hoses or pipes.
6. steel or wooden heavy base.

Pump assembly

NSh32U-3 gear pumps are used to pump oil into the hydraulic systems of many machines:

• tractors YuMZ, KhTZ, MTZ, DT;
• combines NIVA, Sibiryak, Kedr, Yenisei;
• trucks ZIL, GAZ, FAZ, KrAZ, MoAZ;
• dump trucks KamAZ, BelAZ, MAZ;
• excavators;
• motor graders;
• loaders;
• Agreecultural machines. Agreecultural equipment;
• forklifts.

NS devices are manufactured with right and left rotation of the drive shaft, but for installation on a homemade pumping station this difference does not matter, the main thing is to correctly connect the suction hose to the hole labeled “Input”, and the outlet hose to the outlet.

Characteristics of oil pump NSh32U-3:

• Working volume - 32 cm cubic.
• The nominal outlet pressure is 16 MPa.
• The maximum outlet pressure is 21 MPa.
• Nominal rotation speed - 2400 rpm. per minute
• Maximum rotation speed - 3600 rpm. per minute
• Minimum rotation speed - 960 rpm. per minute
• Nominal flow - 71.5 liters per minute.

It can be proposed to use NS devices instead power plant power steering of a KrAZ truck with similar characteristics. This pump also has a gear design.

For a homemade water pump, an electric motor from an old one will be useful. washing machine power 200–300 W. The old “assistant” can no longer compete with modern programmable devices, but its electric motor and pump can serve for a long time.

It is very convenient that most electric motors from washing machines can be connected directly to a 220 V network without modifications, because they have starting windings. Just don’t forget about reliable grounding of the metal body of the electric motor itself, since it works near water. Be sure to connect any homemade product to the network only through fuses or a circuit breaker.

The oil pump works great with water! There is no need to fill the intake hose with water, since the pumping gears provide excellent suction from a depth of 4 meters, with a capacity of 2–2.5 m3. at one o'clock. The filler neck on the intake manifold is completely useless.

Improvements homemade pump

Often the power of a homemade pump is insufficient, and it cannot lift water from a well or deep well. Then you can solve the problem by using one of the methods to increase the suction pressure:

1. Lower the pump as close to the water as possible.
2. Draw a recirculation line from the outlet pipe, and increase the pressure at the suction with the flow from it.

1. Use a compressor to increase the air pressure in the pre-sealed well.
2. Connect another weak pump in tandem.

What if the power goes out? Then it wouldn’t hurt to adapt a gasoline engine from a brush cutter, chainsaw or moped to a homemade pump.

In the article you will find instructions for assembling original pump models, which you can make yourself without any specific skills or knowledge. The cost of the above models is minimal, and sometimes they can even be assembled from scrap materials and household waste.

A water pump is almost an essential item in a country house. household. Manual and mechanized pumps are also used for pumping other types of liquids - fuels, solvents, oils, etc. Opportunity to purchase expensive reliable pump there is not always, but cheap models They break, as a rule, at the most inopportune moment. We will consider options for creating pumps from scrap materials and parts that can be found in every workshop, and their market value is simply insignificant in comparison with a new factory product.

Option No. 1. Water pump for water overflow

A primitive design for pumping water, which can be assembled in 10 minutes, will serve as a convenient tool for working in the garden. This is especially convenient when you need to repeatedly draw water from a barrel with buckets. Essentially, this is a check valve attached to a pipe with an outlet.

To make it you will need a tube, a hose and several necks from plastic bottles assembled.

Progress:

1. We remove the gasket from the cork and cut it 2 mm less than the diameter of the cork, leaving a 3 mm segment untouched.
2. Drill a 10mm hole in the center of the lid.
3. Place the petal in the lid and screw in the cut neck. It will press the remaining segment.
4. We insert the valve into the stem tube and put on a “skirt” from a cut plastic bottle.
5. WITH reverse end put on the outlet hose.

This device is activated by several clicks along the axis of the rod when the intake part with the valve is immersed in water. Then the liquid will flow by gravity as long as there is a difference in levels. The water can then be raised by plunging the rod into the barrel.

This is the only product with a “negative cost”. When creating it, you not only won’t spend anything (except time), but you will also recycle household waste.

Option number 2. Simple DIY hand pump

In this instruction we will give an example of a manual water pumping system, which can be taken as a basis when creating a stationary water-lifting station on a well or well.

A - Classic hand pump diagram. B - Option for a homemade pump from plastic pipes. Device diagram: 1 - inlet pipe; 2 - check valve; 3 - piston; 4 - check valve; 5 - rod; 6 - rod combined with outlet pipe; 7 - pump drain

For work we will need:

1. Pipe sewer PVC 50 mm with bends, plug and sealing cuffs - 1 m.
2. Check valve 1/2" - 2 pcs.
3. PPR sewer pipe Ø 24 mm.
4. Rubber, bolt/nut pairs with washers Ø 6-8 mm.
5. Clamps, bends, fitting clamps, other plumbing parts*.

* The pump design can be customized depending on the availability of spare parts.

Method 1. Drain through the handle

This model is the simplest of the home ones - water rises along the piston rod, which is made of PPR pipe and pours out from above.

1. We cut a pipe Ø 50 mm with a length of 650 mm - this is the basis for the sleeve.
2. We make an end reed valve. To do this, drill 8-10 holes Ø 5-6 mm in the plug and cut out a round piece of rubber (3-4 mm) with a diameter of 50 mm. We secure the flap in the center of the plug with a rivet or bolt (a self-tapping screw is not suitable!). The reed valve is ready.
3. We install the plug into the pipe (sleeve) on the sealant through the seals and additionally fix it with self-tapping screws through the pipe wall.

1. IN PPR pipe(700-800 mm) install a check valve. This can be done using the “hot” method - heat the end of the pipe and insert a fitting with a valve into it, which should allow water to flow in the direction of the pipe (piston rod). Strengthen the connection with a worm clamp while it is warm (before it cools).
2. The piston head can be made from a used 330 ml sealant tube, or rather its nose part. To do this, you need to pre-heat it and place it in a sleeve - this way the head will fit perfectly the required form and size. Then it should be trimmed and installed on the check valve in series using a coupling with external thread or an “American” union nut.
3. We insert the piston into the sleeve and make the top plug. It doesn't have to be sealed, just keep the stem straight.
4. We install a 90° bend on the free end of the rod (pipe). In the future, a hose is put on the hose.

Such a pump is very reliable, but not entirely convenient - the water outlet point is movable, and is also located close to the operator. It can be slightly modified for convenience.

Method 2. Side drain

A 35° elbow tee should be included in the sleeve. The design is identical to the first option, but we make large holes in the piston rod pipe without disturbing the structural rigidity, or use a rod rod. In this case, water will flow into the sleeve and rise by the operator’s reverse force to the point of spouting.

The main advantage of the described pumps is low cost finished design. Repairs are made in a few minutes by replacing (or gluing together) “penny” parts.

Option No. 3. Spiral hydraulic piston

Behind this formidable name lies an ingenious device for supplying water from a river over a short distance. This device is based on a carousel with blades - similar to the wheel of a water mill. The carousel is powered by the river flow.

Pump in in this case is a spiral of flexible pipeØ 50-75 mm, secured with clamps to the wheel. In the intake part (closer to the outer contour) a bucket made of a larger diameter pipe (150 mm) is attached to it.

The main unit is a pipe reducer through which water will flow into the pipeline. It can be taken from factory equipment or a sewage pump. The gearbox is located along the axis of the wheel and is rigidly attached to a fixed base.

The maximum height of water rise will be equal to the length of the pipe (from the intake), which is completely immersed in water during operation. That is, this is the distance in plan from the immersion point to the exit point that the water intake bucket travels. At the moment of immersion, a closed system with air sections, and water passes through the pipe to the center of the spiral.

Of course, such a pump is not suitable for everyone - after all, the activator is the river. But for watering summer period This great option. The cost of such a device is difficult to predict - great importance has the availability of available material.

Option No. 4. Pump from a compressor (airlift)

If your household already has a compressor, do not rush to purchase an additional pump. You can assemble a simple water lift from literally two pipes.

The first pipe serves to supply water. For household needs, Ø 30 mm will be sufficient. The second is needed to supply air from the compressor. Diameter 10-20 mm.

The efficiency of an airlift pump directly depends on the compressor power, immersion depth and delivery height. It cannot exceed 70% due to design features. The efficiency will be equal to the immersion depth divided by the sum of the immersion depth and the ascent height (the entire water path). In most cases optimal power compressor is set experimentally.

Water supply has been the number one priority for the survival of entire cities since ancient times. Today energy saving and natural resources— there are fewer and fewer of them, and they are becoming more and more expensive. Therefore, a partial return to original technologies without electricity and gasoline is a natural phenomenon. Perhaps in the future this will be the key to a healthy and harmonious life on our planet.

Despite the affordable price and a wide range of modern pumping equipment, some primitive models can be made independently. And the point here is not only in acquiring technical skills, but also in a kind of rest, exercise for the body and mind. After reading this article you will know how to doDIY water pump.

About the advisability of making your own

The main disadvantage of factory water pumps is the need to connect to power lines. We must agree that many suburban areas, especially at the beginning of construction, electricity is a rarity.

Moreover, electricity tariffs are constantly rising, and owners report cases of power outages summer cottages know like no one else. It is for this reason that every self-respecting owner should have at his disposal “spare” equipment for pumping water. Such equipment is useful not only when watering the garden - it can also be used at critical moments.

Note! It is recommended to make a piston water pump (or pump-pump, as it is also called), because this simplest option water intake equipment. This requires only minimal technical skills and a small set of tools.

Operating principle of the pump

The housing contains a cylinder with a piston moving inside it. The cylinder itself has inlet and outlet holes equipped with valves. To facilitate pumping, a spring is installed between the lower valve and the piston - it will attract the piston.

The air in the cylinder is rarefied during the movement of the piston, as a result of which the inlet opens and water is drawn inside. Further, when the piston moves in reverse side, the valve closes and water leaves the cylinder through the outlet hole. The only engine here is the applied muscular efforts, and the performance of the device depends not only on them, but also on the volume of the cylinder.

Note! A piston pump is unlikely to be able to provide a complete water supply to the site, but in emergency cases it can be used to pump some water, for example, to water the beds.

In most cases, wells of insignificant depth - Abyssinian wells - are equipped with pumping pumps.

Piston pump manufacturing technology

There is nothing complicated in creating a pump, the main thing is to prepare everything you need and follow the instructions below.

Stage 1. First, a cylinder is formed. This will require metal pipeø10 cm and 1 m long. To ensure smooth movement of the piston, inner surface the pipes need to be treated with sandpaper (for convenience, the latter is placed on a wooden stick).

Note! It is not necessary to use a round pipe for the pump; the configuration can be very diverse - from square to hexagon.

Stage 2. Brackets are welded to the cylinder, with which the pump lever will be attached. They need to be installed so that the lever fits between them freely. Metal corners are used to make brackets.

Stage 3. A hole is drilled in the upper part of the cylinder for the drain pipe. The pipe itself can be located either opposite the brackets or to the side of them.

Stage 4. Next you need to make a lid that would cover the lower end of the case. In the presence of welding machine the end is welded with a metal plate, but it is worth knowing that the lid can also be made from scrap materials. This could be, for example, moisture-resistant larch, the strength of which only increases when in contact with water.

Step 5. The top cover is optional, but it is better to install it in order to increase the efficiency of the device. The lid will prevent the collected water from spilling. There are no special requirements regarding strength, so both wood and plastic are used in manufacturing, the main thing is to make a hole for the rod.

Note! The hole should be slot-shaped, since the rod will move parallel to the lever.

• a metal disk 3-4 cm thick, creating a difference in pressure;
• a piece of rubber of the appropriate size, 5 cm thick.

Several ø1 cm holes are made in the piston, after which it is covered with an elastic band. Then a through hole is made in the center of the connected parts to fix the rod.

Video - How a piston pump works

Stage 7. After this, you can begin making the rod. For this, a metal rod ø1-1.5 cm is used - one end of it is inserted into the center of the piston and screwed from below with a nut, the second is attached to the lever.

Stage 8. To make the lever, you will need an iron pipe ø3 cm, in the center of which a long bolt is attached. Once installed, this bolt will run between the two brackets. One end of the pipe is flattened and a hole is drilled in it for a bolt, with which the rod will be fixed. The other end of the lever, which the person will hold with his hands, is wrapped insulating tape or a thick cord.

Stage 9. The inlet valve is a piece of dense rubber (its shape must match the cross-section of the cylinder). The valve diameter must be smaller than the body diameter, but larger diameter well head. A guide is attached to the center of the valve, which will return it to the body after each cycle. The length of the guide must be greater than the distance between drain hole and the lower end of the body.

Stage 10. The pump housing is mounted on the pipe. In this case, it is advisable to cut a thread at the inlet hole of the cylinder and the head of the well - this way there will be no problems with the connection.

Note! You can increase the strength of the device by using additional supports, welded to the body and secured to a metal frame lying on the ground.

A rod leading from the inlet valve is lowered into the hole made in the lower end of the housing, after which the piston is inserted. The pump lever is connected to the brackets with bolts and attached to the rod. That's it, the piston pump is ready for use.

Note that the pump can be installed not only in a shallow well, but also with its help to pump out water from a nearby reservoir. For this purpose, it is not the head of the Abasin well that is connected to the inlet valve, but a hose that needs to be thrown into the reservoir. In this case, the pump will not create pressure, which is why it will not be able to lift water above the level of the sewing neck. It is advisable to place it next to the pump big barrel and fill it - this will allow you to use water as needed.

If you have old car brake chambers lying around, you can also use them to create a water pump. The sequence of actions in this case should be as follows.

Stage 1. The brake chamber is disassembled, all holes in the body are carefully sealed.

Stage 2. Inlet and outlet valves are installed in the lower part of the body, and a hole for the rod is made in the upper part.

Stage 3. Rubber is used as a piston - it is clamped between the lid and the bottom of the chamber. The piston is connected to the rod with bolts (preferably through gaskets).

Stage 4. A bracket is installed on the side to fix the lever.

Stage 5. The lever is connected to the bracket, and one of its ends is connected to the rod.

The operating principle of this pump is practically no different from the design described above: after each press of the lever in the lower part of the housing, increased/decreased pressure is created, which leads to the opening of the valve at the inlet/outlet.

A little-known design that operates using the power of fire. For production you will need a sealed iron barrel with a capacity of at least 200 liters.

Stage 1. First, a furnace is built to heat the structure. The best option– small brick stove with a grate.

Stage 2. Then a discharge valve is installed at the bottom of the housing.

Stage 3. A rubber hose is inserted into the hole on the top cover (it should fit as tightly as possible). Installed on the outer end of the hose strainer, after which the hose is immersed in a lake or river.

Stage 4. Several liters of water are poured into the barrel, after which the stove is lit. The outlet valve must be closed. The heated air, expanding, goes into the reservoir. Next, the fire is extinguished, and the air, having cooled and, accordingly, contracted, will draw water into the barrel.

If desired, fire can be replaced with solar energy. To build such a pump, you need to perform the following steps.

Stage 1. A grid of metal tubes is made, there should be only one exit. Next, the finished grille is coated with black paint.

Stage 2. The inlet is connected to an aluminum can.

Stage 3. The can lid is equipped with inlet and outlet valves. Nipples from old car tires are ideal for this.

Stage 4. A small rubber container, for example, a car inner tube, is connected to the grid terminal inside the can.

Stage 5. The outlet on the cover is connected to a hose leading to a reservoir or well. The other end of the hose is taken out of the reservoir, equipped with a watering can tip and installed above the grate.

This pump works as follows. The grate heats up, and the air in it expands and inflates the rubber container. As a result, the air is forced out of the can and enters the reservoir, where, rising, it carries water with it. A small amount of water flows into the watering can to cool the grate, after which the cycle repeats.

Note! Such a pump can be somewhat modernized by pumping propane-butane into the grill instead of air.

As we see, with the help of skill and minimum set tools you can make a water pump from almost anything. To get acquainted with other technologies, we recommend watching the thematic video.

Video - Making a water pump

Having purchased a house with a beautiful garden plot, many people, first of all, think about how to improve it as quickly as possible and make it comfortable and cozy.

In many ways, this depends on the supply of electricity, heat and water supply, which plays a key role in the improvement and care of a summer cottage. But what to do when the house is located far from public utilities, but the garden needs to be watered? In this case, some summer residents try to buy all kinds of pumping units that will provide water supply country cottage area.

But more experienced and skillful summer residents try to save money even on this equipment, so they try to make a water pump with their own hands. And the point here is not only about saving, here is the opportunity to show your imagination to its full potential, and with benefit.

As a rule, a summer resident who is interested in making a water pump with his own hands goes to the Internet to search for a diagram homemade device. And what does he see there? The entire network is replete with various drawings and diagrams of all kinds of pumps and pumps, sometimes even completely incomprehensible. And it can sometimes be very difficult to choose just one unit.

To save the summer resident’s time searching desired device online, in this article we tried to summarize all the information about homemade pumps. Therefore, we will describe the most interesting and low-cost options for hand-made water pumps.

Suitable species

The most popular water pumps that you can make yourself are the following pumping mechanisms:

Let us describe in more detail the manufacturing technology of each of the indicated options for homemade pumping units.

Piston pump

A piston water pump is also popularly known as a “pump pump”.

As a rule, the design of such a mechanism consists of the following elements:

• working cylinder;
• piston;
• intake and exhaust valves.

The operating principle of a homemade piston pump consists of the following important points:

• when the piston moves, the inlet valve opens and water is sucked into the pump;
• When the piston moves back, the inlet valve closes, and the outlet valve opens accordingly, and water comes out.

As you can see, the structure and operating principle of this homemade pump is very simple, so its manufacture will not be difficult, the main thing is to prepare all the necessary materials.

To do this you will need:

The manufacturing procedure consists of the following important steps:

Worth considering: A piston pump is used only for pumping water from shallow wells or other shallow sources.

Wave pump

This type of pump is considered the simplest design, easy to assemble, and at the same time, is a fairly effective pumping mechanism.

For a summer resident who has a pond near his property, a wave pump will be an indispensable source of moisture.

To make this type of pump you will need the following materials:

• heavy log impregnated with waterproof mastic;
• 2 valves;
• a piece of corrugated pipe;
• flexible hose for water supply;
• thick wooden plank;
• 2 brackets.

Installation of a wave pump consists of the following important points:

• a wooden plank is firmly driven into the bottom of the reservoir;
• two brackets are fixed on top of the plank and at a distance of 50–60 cm from the water level;
• a corrugated hose is fixed between them, both ends of which are equipped with valves;
• the lower end of the corrugation is stably fixed on the log.

The principle of operation of such a pumping mechanism will be that the log, under the influence of waves, will move up and down, while corrugated pipe will collect water, which through flexible hose will be supplied directly to the dacha plot.

Stove pump

For some people, the name of the pump is misleading.

It is worth understanding that this design is not intended for heating - it can be used, for example, for watering garden beds.

To make such a pumping mechanism you will need the following materials:

• metal barrel with a volume of 200 l;
• outlet with shut-off valve;
• rubber hose;
• mesh filter;
• blowtorch.

The manufacture of a stove-pump is carried out in the following several sequential steps:

The operating principle of such a pumping mechanism consists of the following important points:

• the barrel is filled with 5–10 liters of water, and a blowtorch is lit under it;
• the generated steam through the hose will displace air into the reservoir;
• blowtorch stew, and, accordingly, the barrel begins to cool, and as a result, the pressure in it begins to drop;
• the result of these actions will be that water from the reservoir will begin to flow into the barrel.

Mini shower pump

To begin with, it is worth noting that a mini-pump of this design is also commonly called a “treadmill shower.”

The manufacturing process for a mini-pump is quite simple.

For its construction the following materials will be needed:

• foot auto pump;
• container with a tight lid;
• check valve;
• 2 pieces of rubber hose or any flexible tube.

The operating principle of the mini-pump consists of the following points:

• the pump, hermetically connected to the container, begins to create excess pressure in it;
• under the influence of increased pressure, water begins to flow out through another sealed hose, while the check valve prevents water from entering the pump.

It is worth noting: The pressure of the outgoing water can be adjusted by the frequency of pressing the pump.

Solar Powered Water Pump

It is important that the water supply to personal plot can be done using alternative sources nutrition, in particular solar energy.

To make a solar water pump, you will need the following materials:

• milk can;
• rubber balloon in the shape of a pear;
• 2 check valves;
• flexible hoses;
• a set of sections of thin-walled metal pipes.

The procedure for manufacturing a pumping mechanism of this type consists of the following important points:

The operating principle of this type of water pump consists of the following points:

• the grill heats up well under the influence of the sun;
• the air heated inside begins to flow into the rubber bulb, thereby inflating it;
• Thus, excess pressure is created in the can, which is forced out into the reservoir through hoses;
• after cooling the circuit with water, the pressure in the can begins to drop, which in turn entails the supply of water from the reservoir.

In this article we described the most popular devices for supplying water to a personal plot, and also talked about important nuances their manufacture. We hope that by using the information presented in the article, you will certainly secure your summer cottage required quantity water.

Watch the video in which an experienced user explains in detail how to make a manual water pump with your own hands:

After purchase land plot the summer resident begins to decide the most important issues: you have to start somewhere in order to settle down. The most important thing is to provide yourself with water. Indeed, since life arose in water, without it, all living things cannot exist for a long time. You can bring water from somewhere, but only for personal needs. The watering problem cannot be solved using this method. It’s good if there is water at least close to the site. Any, even small, body of water will suit you: a river or at least a stream. Ideal option there is a spring, but such luck is rare. All that's left is to get a pump. By the way, at first homemade will do water pump. Its use will alleviate the problem.

This pump model, which does not require electricity to operate, can be used by craftsmen who are lucky enough to purchase a plot of land on the banks of a small but very stormy river.

The hose is laid in the barrel in even turns without creases or kinks. And the entire structure as a whole looks rather simple, but with its help water is regularly supplied to the shore

To create a pump you will need:

• a barrel with a diameter of 52 cm, a length of 85 cm and a weight of approximately 17 kg;
• hose wound in a barrel with a diameter of 12mm;
• outlet (supply) hose 16mm in diameter;

There are also restrictions for the immersion environment: the working depth of the flow should not be less than 30 cm, the speed of water movement (current) should be 1.5 m/sec. Such a pump ensures that water rises to a height of no more than 25 meters vertically.

Components: 1 - outlet hose, 2 - sleeve coupling, 3 - blades, 4 - polystyrene foam floats, 5 - spiral winding of the hose, 6 - inlet, 7 - bottom of the structure. The barrel floats perfectly

Details of using this pump can be seen in the video.

Option #2 - homemade wave pump

This pump also takes advantage of the river nearby. In a reservoir without a current, such a pump is unlikely to be effective. To make it you will need:

• accordion-type corrugated pipe;
• bracket;
• 2 bushings with valves;
• log.

The pipe can be made of either plastic or brass. Depending on the material of the accordion, the weight of the log must be adjusted. A log weighing more than 60 kg will fit a brass pipe, but a not so heavy load will be suitable for a plastic pipe. As a rule, the weight of the log is selected practically.

This version of the pump is suitable for a river and not with the most stormy current, it is important that it is simple, then the “accordion” will contract and the water will be pumped

Both ends of the pipe are closed with bushings having valves. On one side, the pipe is attached to a bracket, on the other, to a log placed in water. The operation of the device directly depends on the movement of water in the river. It is its oscillatory movements that should force the “accordion” to act. The expected effect at a wind speed of 2 m/sec and with an increased pressure of up to 4 atmospheres can be approximately 25 thousand liters of water per day.

As you understand, the pump is presented in a simplified version. It can be improved by eliminating unwanted torque on the log. To do this, fix it in a horizontal plane by installing a ring stop on the lift using a bolt. The pump will now last longer. Another improvement option: soldered tips at the ends of the pipe. The bushings can simply be screwed onto them.

Particular attention should be paid to preliminary preparation logs Don't forget that it will be placed in water. We prepare a mixture of natural drying oil and kerosene at a ratio of one to one. We impregnate the log itself with the mixture 3-4 times, and the cuts and ends, as the most hygroscopic, six times. The mixture may begin to harden during operation. When heated in a water bath, it will regain fluidity without losing other properties.

Option #3 - a furnace that creates a pressure difference

The craftsmen whose idea was embodied in this miracle of engineering called their brainchild a “pump furnace.” They, of course, know better, but at the initial stage of its operation this pump looks like a samovar. However, it doesn’t really heat the water, but creates a difference in pressure, due to which its work is carried out.

For such a pump you need:

• steel barrel 200 liters;
• Primus or blowtorch;
• pipe with tap;
• mesh nozzle for hose;
• rubber hose;
• drill.

The pipe with the tap must be cut into the bottom of the barrel. Close the top of the barrel with a screw cap. A hole is pre-drilled in this plug and a rubber hose is inserted into it. The mesh nozzle is needed to close the second end of the hose before it is lowered into the reservoir.

This version of the pump can even be called ingenious and, most importantly, this “device” will probably work well

Approximately two liters of water are poured into the barrel. They put it under a barrel a heating element(primus stove or blowtorch). You can simply light a fire under the bottom. The air in the barrel heats up and exits through a hose into the reservoir. This will be noticeable by gurgling. The fire is extinguished, the barrel begins to cool, and due to the low internal pressure, water from the reservoir is pumped into it.

On average, it takes at least an hour to fill a barrel. This is provided that the hole in the hose has a diameter of 14 mm and a distance of 6 meters from the place from which the water is to be raised.

Option #4 - black grille for sunny weather

For this product you will need special devices. Where, for example, do you get a black grille, the hollow tubes of which contain liquefied propane-butane? However, if this part of the problem is solved, the rest does not cause any particular difficulties. So, there is a grille, and it is connected to a rubber bulb (balloon), which is placed in a can. There are two valves in the lid of this can. One valve lets air into the container, and through the other, air with a pressure of 1 atm exits into the air duct.

It’s really better to make the grate black, because black products always heat up more actively under the bright summer sun

This is how the system works. Watering the grate on a sunny day cold water. Propane-butane cools, and the gas vapor pressure decreases. The rubber balloon is compressed, and air enters the can. After the sun dries the grate, the steam will again inflate the bulb, and pressurized air will begin to flow through the valve directly into the pipe. Airlock becomes a kind of piston that expels water through the shower head onto the grate, after which the cycle repeats.

Of course, we are not interested in the process of watering the grate itself, but in the water that collects under it. Experts say that the pump functions perfectly even in winter time. Only this time, frosty air is used as a coolant, and the grate is heated by water extracted from the ground.

Option #5 - supercharger from a plastic bottle

If the water is in a barrel or other container, then using a watering hose in this case seems problematic. It's actually not that complicated. You can literally use scrap materials to construct a homemade pump for pumping out water, which will work on the principle of compensating the level of liquid in communicating vessels.

Water injection occurs as a result of several translational movements. The valve, which is located under the lid, does not allow water to return to the barrel, which forces it to flow out when its volume increases. This seemingly insignificant structure is a great help in dacha work.

For a hand pump you need:

• a plastic bottle, the lid of which must have a plastic membrane gasket;
• hose of suitable length;
• a standard tube whose diameter corresponds to the size of the bottle neck.

How exactly such a pump can be assembled and how it will function, look at the video, where everything is explained in detail.

Option #6 - part from a washing machine

The habit of buying new things when there are old analogues is very ruinous. I agree that an old washing machine is no longer able to compete with new models, but its pump can still serve you well. For example, it can be used to pump out water from a drainage well.

The washing machine has long served its purpose. It was simply supplanted by new models with new capabilities. But her heart, the pump, is still capable of serving its owner.

The motor of such a pump requires a 220V network. But it is better to use an isolation transformer with reliable insulation of the input and output windings to power it. Don’t forget about high-quality grounding of the core or metal body of the transformer itself. We compare the power of the transformer and the motor.

We use centrifugal type pump, so we put a valve at the end of the hose lowered into the water, and fill the system with water. The check valve, which is shown disassembled in the photo, can also be removed from the washing machine. And the blue ground stopper just fit perfectly so that the extra hole would also be closed. Surely you have something similar in your supplies.

Literally from garbage, as it turns out, you can assemble a completely functional thing that not only works, but does its job well and quickly

The resulting homemade pump works very well, pumping water from a depth of about 2 meters at a decent speed. It is important to turn it off in time so that air does not get into the system and you do not have to fill it with water again.

Option #7 - Archimedes and Africa

Everyone remembers very well the story about the screw invented by Archimedes. With its help, water supply was carried out even in ancient Syracuse, which did not know electricity. A very ingenious use of the Archimedes screw was invented in Africa. The carousel pump serves both as entertainment for local children and as a completely functional structure that provides water to a small settlement. If you have children and they have friends who love to ride the carousel, take this experience into your arsenal.

1- children's carousel, 2- pump, 3- aquifer layer, 4- water tank, 5- water column, 6- water return pipe in case the tank overflows

As you can see, there are a lot of possibilities for water supply. And electricity may not be involved at all in this matter. It turned out that even a schoolchild can make some water pumps with his own hands. It is important to have a desire, a clear head and skillful hands. We'll give you ideas.
