Product Features

Anti-overload Designed Impeller

The radial force of impeller caused by overload can be reduced by vane -type design which prevent fall off of blades and break of shaft . The impeller is designed with wide channels to prevent blocking by solid particles and winding by fiber in flow.

Intelligent Online Monitoring

The operation of this series product can be controlled by a number of sensors automatically. The wiring room and motor cavity are located with water leakage sensors, and the oil chamber is located with water & oil probe, while the upper and lower bearing are protected by sensors to test temperature increasing of motor.
