# cost of rpm centrifugal pump with kw

###### Centrifugal Pumps

it is important to understand that the pump will pump all fluids to the same height if the shaft is turning at the same rpm The only difference between the fluids is the amount of power it takes to get the shaft to the proper rpm The higher the specific gravity of the fluid the more power is required Centrifugal Pumps are constant head ....
