It is mainly composed of pump body, impeller, motor housing, bearing and motor. The centrifugal impeller is connected to the motor directly. The high-rotating impeller generates a centrifugal force and drives the transformer oil to flow through the volute. Then the volute converts a part of kinetic energy of transformer oil to pressure energy. So that the transformer oil flows out from the pump outlet and leads to the circulation of the transformer oil.
1.High electric power;
2.Smaller impeller with higher performance;
4.Convenient for installation.
Widely used in the cooler of wind turbine generator and locomotive.
