Description

Horizontal Multistage Pump A horizontal multistage pump is a high-pressure centrifugal pump designed with multiple impellers mounted on a horizontal shaft inside a single casing. Each impeller increases the pressure of the liquid step by step, allowing the pump to deliver high pressure with smooth and efficient flow. These pumps are widely used in industrial, commercial, and municipal applications where high-pressure water or fluid transfer is required. Working Principle The liquid enters the pump through the suction inlet and passes through a series of rotating impellers. Each stage increases the pressure of the liquid before it moves to the next stage. After passing through all stages, the fluid is discharged at high pressure through the outlet.
