Multistage centrifugal pumps are used in various industrial applications due to their ability to transfer fluids at higher pressures. Here are some industries that use multistage centrifugal pumps: Fire fighting – Generates high-pressure water used in extinguishing fires. Boiler feedwater – To pump feedwater into a steam boiler. High-pressure cleaning – Generates a high-pressure stream of water to clean dirt and dust off objects like cars, windows, etc. Reverse Osmosis – Used for desalination. Irrigation – Multistage pumps are used to pump water via an irrigation system. Water circulation – Multistage pumps add pressure to the system, helping in the continuous circulation of water. Snowmaking – Used in pressurizing water for artificial snow generation.

Centrifugal pumps are one of the most popular and frequently used pumps in the world. They can be found in numerous industrial applications. Depending on the application, the right centrifugal pump has to be chosen. If you’re in the market shopping for centrifugal pumps, you would have come across the term “multistage centrifugal pumps.” Wondering if it’s the right choice for your needs? Allow us to help.
As the names imply, the key difference between the two is the number of impellers (also known as stages). Single-stage centrifugal pumps have only one impeller. On the other hand, multistage pumps have two or more impellers. The impeller plays a crucial role in the operation of a centrifugal pump. It pressurizes and transfers the fluid/liquid. Since multistage pumps have more than one impeller, the flow rate and pressure ranges in a multistage are more efficient than single-stage pumps. Inside a multistage pump, each impeller acts like a stand-alone single-stage centrifugal pump. Hence, it works like a chain of single-stage pumps connected linearly. As the liquid moves from one stage to the next, the pressure rises while the flow remains constant. As a result, multistage centrifugal pumps generate higher power and higher pressure with small motors, thereby using less energy.
Horizontal multistage pumps are the most commonly used pumps and are used in several of the applications mentioned above. In this pump, the liquid travels horizontally through several impellers. Horizontal pumps can handle higher flow rates than vertical pumps (the one exception to this rule is vertical turbine pumps that can handle higher flow rates). It’s easy to identify horizontal multistage pumps via their segmented casing. Despite all the benefits, horizontal multistage pumps have certain drawbacks. They are: Maintenance intensive Need skilled pump operators It can be more expensive compared to vertical multistage pumps

Also known as booster pumps, these have a multistage impeller that propels water about two times higher and farther than standard circulation pumps. Use them in applications such as water delivery, irrigation, and pressure washing. The motor is totally enclosed fan-cooled (TEFC) for use in dusty, dirty, and damp environments. Pumps are gravity fed and require an elevated liquid source to fully fill the pump before turning on. Do not run dry or use with solids.
Note: If flow control is needed, place valves or reducers on the discharge side; never restrict the inlet of a pump with a valve or reducer.
Designed for long-life and trouble free service, the 8K series are a superior line of multistage centrifugal pumps. Originally engineered for booster, water purification, and hot water applications, many other industries have adopted this product due to its reliable performance.
The 8K series are truly an industrial grade pump, consisting of 304 or 316 SS hydraulic assemblies constructed with cast stainless steel flanges for maximum installation support. Different mechanical seal face options are available and incorporate a separate thrust bearing in place of motor bearings, adding to the robust design of this product. The 8K also features tungsten carbide lower pump bearings and sleeves – standard construction for all services, providing maximum operating life. Count on the 8K to get the job done.
Designed to meet the hygienic requirements of the dairy, food and beverage and personal care industries, LKH Multistage centrifugal pumps increase process productivity while providing high efficiency and gentle product handling.
Suitable for high-pressure applications with low capacity requirements, this compact, efficient pump is ideal for use in reverse osmosis and ultrafiltration processes. One pump can replace up to three booster pumps on a production line, saving valuable floor space.
