WHAT IS ROTOR?

In wet rotor pumps, the pressurized fluid is allowed to circulate around the rotor through the rotor liner and wet and lubricate the carbon bearings on which the rotor shaft sits. In this way, the heating problems in the winding and bearing group of the motor are eliminated. Wet rotor pump motors do not have cooling fins and cooling fans. Therefore, they work silently. In addition, the shaft seal, which is one of the most important parts of the pump body, which provides impermeability in pumps, is not used in pumps with wet rotors and low service and maintenance costs occur.

In addition to many advantages, wet rotor pumps are generally used in heating and cooling circulation because they operate at lower efficiency than dry rotor pumps and cannot be produced above a certain capacity. Because circulation systems are closed loops, pumps with very high pressure values ​​are not used.
