CIP Centrifugal pump

Character of sanitary CIP Centrifugal pump :

1. The flow direction of water along the Du flow direction of Bai centrifugal pump is along the axial direction of the impeller, and it flows out perpendicular to the axial direction.

2. Because centrifugal pump relies on impeller inlet to form vacuum suction, so before starting, it is necessary to inject water into pump and suction pipe, or use vacuum pump to exhaust air to form vacuum. Moreover, pump shell and suction pipeline must be strictly sealed without air leakage, otherwise, vacuum can not be formed and water can not be sucked.

3. Because it is impossible to form absolute vacuum at the impeller inlet, the suction height of the centrifugal pump can not exceed 10 m. In addition, the actual allowable installation height (the height between the pump axis and the suction water surface) is far less than 10 m due to the loss along the way caused by water flow through the suction pipeline. If the installation is too high, it will not absorb water; in addition, because the atmospheric pressure in the mountain area is lower than that in the plain area, the installation height of the same water pump in the mountain area, especially in the high mountain area, should be reduced, otherwise it can not absorb water.
