A multi-stage pump is a type of centrifugal pump that uses multiple impellers arranged in series within the same housing. Each impeller increases the pressure of the fluid as it passes through, making the pump capable of achieving higher pressures than single-stage pumps. Multi-stage pumps are commonly used in applications like boiler feedwater, reverse osmosis, pressure boosting, and high-rise water supply systems. They are efficient for handling high-pressure requirements with relatively low energy consumption. Proper maintenance, including regular inspection, cleaning, and checking for wear, ensures optimal performance and longevity of multi-stage pumps.
