Versatile Bronze High Lift Booster Pump for Mining and Boiler Feed

Key parts include the stator (inlet, middle, spit sections, guide vanes), rotor (shaft, impeller, balance plate), bearings (rolling and sliding), and shaft seals. It also features a thrust balance device like a balance disc or drum to manage axial forces.

It operates by having one impeller feed into the next. Liquid enters the pump and passes through multiple impellers in sequence. The number of impellers depends on the required discharge pressure, with each stage adding to the total head.

They are used for mine dewatering, boiler feed systems, reverse osmosis, high-rise building water supply, snow making, condensate return, irrigation, fire hydrant systems, and high-pressure cleaning.

A single-stage pump uses one impeller, while a multistage pump uses two or more. Multistage pumps include additional components like diffusers to channel fluid between stages and a thrust balance device to handle higher pressures and axial forces.

They offer better hydraulic fit, higher efficiency, and greater reliability compared to high-pressure duty pumps. They can be configured for multiple duty points, run quieter at lower speeds, and allow for precise adjustment of the duty point by trimming impellers.
