Multistage Pumps
Multistage water pumps are commonly used when liquids need to be transported at high pressure. This is achieved by using multiple impellers, known as stages, in the pump unit. As the flow progresses through its multiple stages, pressure builds within the pump enabling it to move contents a longer distance than would otherwise be possible. Multistage pumps can be supplied in vertical and horizontal configurations.
What are Multistage Pumps
Multistage pumps are a type of centrifugal pump designed to move fluid through multiple stages of impellers in series. Each stage consists of an impeller and a diffuser. The primary advantage of this configuration is that it allows the pump to achieve higher pressures than single-stage pumps, making them ideal for applications requiring significant pressure boosts.
Overall, multistage pumps are highly versatile and efficient solutions for high-pressure applications across various industries.
Key Features of Multistage Pumps:
- High Pressure: By passing the fluid through multiple stages, each adding its own pressure increment, these pumps can achieve much higher pressures than single-stage pumps.
- Efficiency: They are typically more efficient for applications requiring high head (pressure) compared to single-stage pumps.
- Flexibility: The number of stages can be adjusted to meet specific pressure requirements, offering flexibility in their design and application.
- Smooth Flow: Multistage pumps provide a more constant and smooth flow compared to single-stage pumps, which can be beneficial in many industrial processes.

Applications
Multistage pumps are often used in pressure boosting systems where circumstances demand constant pressure and flow. These uses include high-density living, industrial applications requiring substantial wash down facilities, boiler feed systems, jacking pumps for fire hydrant systems, fire hose reel supply and irrigation systems.
A number of motor options can drive multistage pumps from mains and solar powered electric motors to diesel and petrol motor options.
Ideally, vertical multistage pumps are suitable for clean water applications such as:
- Portable water in high-rise, high-density buildings and complexes
- High-pressure shower systems
- Boiler feedwater and
- Desuperheater feed
Typical applications of horizontal multistage pumps are:
- Reverse osmosis
- Boiler feed
- Shower
- Spray
- Cogeneration
- Pressure boosting
- High-pressure cleaning
- Snowmaking
- Condensate and
- Mine dewatering
