Multistage centrifugal pumps have been one of the most popular types of pumps in recent years. Their ability to provide engineers with a flexible range of flow and head, along with their high degree of energy efficiency makes them a great choice for many applications. Could they be right for yours?
About Multistage Centrifugal Pumps
Multistage centrifugal pumps have multiple liquid chambers (or stages) that are connected in series. Fluid enters the first chamber at suction line pressure and leaves at some elevated pressure. Upon leaving the first stage, the fluid enters the second stage where the pressure is increased further.
The more stages the pump has, the higher the final discharge pressure. These pumps have the unique ability to produce higher and higher pressures with the addition of every stage, but flow range always remains constant for a given rpm.
There are a couple different types of multistage pumps. Those with a horizontal shaft, and those with a vertical shaft.
