Description
Three-speed circulation pump Gilex Compass 25-80 with a “wet” rotor is designed for operation in heating systems, used for circulation in hot water supply systems, as well as in refrigeration and air conditioning systems with stable or slightly varying flow rates. Depending on the needs of the network, using a simple and convenient switch, you can set the required rotation speed.

Pumped media
The pump pumps clean, non-viscous and non-aggressive liquids that do not contain particulate matter or fibers.
High reliability
Using a sealed sleeve, the pump and electric motor form a single unit without shaft seals, which has 2 sealing gaskets. The bearings are lubricated by the pumped liquid.
The ceramic plain bearing system makes the pumps durable and quiet due to the high hardness and low coefficient of linear expansion of the ceramic.
Ease of installation
The pump should be installed in horizontal position. When starting, it is necessary to ensure ventilation of the protective sleeve, for which the screw plug of the electric motor is removed. Within a short time, the remaining air is forced through the hollow shaft into the hydraulic system.
Gilex Compass pumps are used for pumping hot water or coolant in heating systems. Moreover, these pumps can be used for transportation cold water in systems not associated with drinking water supply.
Design and operating principle
The main design elements of the circulation pump are shown in the figure.
Pump Compass, like most centrifugal pumps, does not have self-priming, that is, before starting it must be filled with liquid. When power is supplied to the drive motor 1, the rotor 2 begins to rotate, which is connected to the shaft 3, driving the impeller 4, which acts on the liquid, directing it from the suction channel 5 to the discharge line 6. The structural elements are located in a collapsible housing 7.

Installation and maintenance of pumps Compass
Circulation pumps may be installed in the following positions.
Do not install pumps in the following manner.
All circulation pumps must be primed before starting. To completely fill the pump, you can unscrew the plug.
Possible problems
Pump noise
The causes of noise may be:
- Increased fluid resistance in the pipeline
- Air in the pump
In the first case the noise may be caused by too much high speed currents, in this case, you can (if the system allows it) reduce the speed by switching the corresponding switch on the pump.
Also, the presence of air in the heating system can create noise. In this case, it is necessary to remove air from the system.
The second common cause of noise is the presence of air in the pump. In this case, you need to fill the pump with water, unscrew the plug, and wait for the water to flow out. When performing these actions, it is necessary to de-energize the pump and secure electrical connections from getting wet. Be careful the system may be full hot water. When working with the pump, generally accepted safety standards must be observed.

Description
Circulation pump GILEKS Compass (0280) 25/80
Circulation pump GILEKS Compass 25/80 (0280) is used in heating systems for pumping water into pipes, heating radiators with insufficient initial pressure. Designed for household use. The pump is designed for heating systems in houses with 3 floors. For proper operation of the circulation pump GILEX Compass 25/80, the device cannot be used in systems with drinking water, and it is also important to maintain the temperature of the circulating fluid from +10 to +110 degrees Celsius. Thanks to the housing made of cast iron coating, the circulation pump is protected from corrosion, which extends the standard service life of the device. The power of the device is 245 W, productivity is 200 liters per minute.
Advantages
· Three operating modes of the pump, which allows you to select a convenient shaft rotation speed for operation.
· Mechanical control.
· Small dimensions of the device.
· Spare nuts included.
· Powerful electric motor (245 W).
· Equipped with an air release valve.
