A centrifugal pump with a single impeller that can develop a differential pressure of more than 150 psid between the suction and the discharge is difficult and costly to design and construct. A more economical approach to developing high pressures with a single centrifugal pump is to include multiple impellers on a common shaft within the same pump casing. Internal channels in the pump casing route the discharge of one impeller to the suction of another impeller.

Javelin Vertical Multistage Pumps

Multistage Pumps Multistage pumps refer to the different stages of pumping in the process of forcing liquid, typically water, through its components. Multistage pumps are common across applications where liquids need to be transported with high pressure, achieving this with the use of multiple impellers or stages in the body of the pump. As the…
