The efficient speed and water absorption capacity of the sanitary pump ③
3. Allow the suction height to indicate the water absorption performance of the centrifugal pump to determine the installation height of the negative pressure pump . It is represented by the symbol Hs and its unit is meter. It should be pointed out that the Hs indicated on the nameplate refers to the maximum suction lift of the sanitary pump itself, and it does not consider the loss head of the suction pipe. In the centrifugal pump series, Hs=2.5-8.5 meters. Within this range, each pump has its own allowable value. If it is exceeded during installation, the pump will not be able to pump water.
It can be seen that after we correctly understand the performance parameters of the water pump, we can choose and use the Sanitary pump reasonably.
