Why use a shroud? 1. Reduce the temperature rise of the motor, extend the life of the electric pump, reduce the temperature rise of more than 10K, improve the motor efficiency, the working principle: when the water well out of the water layer above the motor or in the pond, reservoir use, the water flow directly from t...

The impeller is generally composed of parts such as wheels, wheel covers and blades. The fluid rotates at high speed with the impeller under the action of the impeller, the gas is affected by the rotation of centrifugal force, and the expansion of pressure flow in the impeller, which increases the pressure after the im...
