Vertical Multistage Pump aquaculturefrance

Vertical Multistage Pump

A vertical multistage pump is a centrifugal pump composed of several stages (impellers or chambers) arranged vertically. Each stage gradually increases the fluid pressure, allowing the pump to reach high heads. It is designed for pumping clean (non-loaded) liquids and is ideal for applications requiring high pressure with moderate flow rates.
