Key Features

Suction impeller-Wider inlet diameter reduces velocity of liquid for reduced friction and increased suction capability.

U-turn channels-Salient rounded edges ensure a balanced velocity allocation of liquid to reduce losses and increase hydraulic efficiency.

Alancing system-Uses the force of pumped liquid to reduce load on mechanical seal and wear on the bearings.

Seal housing-self-cleaning to ensure seal longevity.

Types of Multistage Pumps Available

Horizontal Multistage Pump

This type of pump has multiple impellers mounted on a horizontal shaft. The liquid enters the first impeller, and its pressure is increased as it passes through each subsequent impeller.

Vertical Multistage Pump

As the name suggests, this pump has multiple impellers arranged in a vertical configuration.

Axial Split Casing Multistage Pump

This type of pump has a horizontally split casing, which allows easy access to the impellers for maintenance or repair.

Radial Split Casing Multistage Pump

Unlike axial split casing pumps, the casing of this pump is split radially, allowing access to the impellers from the side.

Applications

Boiler feedwater

Multistage pumps are crucial in boiler systems, where they are used to deliver feedwater to boilers at high pressures. This ensures efficient steam generation and prevents damage to the boilers caused by low water levels.

Mining

In mining operations, multistage pumps are utilized in dewatering applications to remove water from underground and open-pit mines. They are also used for slurry transfer, tailings disposal, and heap leaching processes.

Desalination

As the demand for fresh water continues to grow, desalination of seawater has become an important process.

Power generation

Multistage pumps are used in power plants to transport and circulate cooling water. They are also employed for boiler feedwater, condensate extraction, and other related processes.

FAQ

Q: What does the term multistage mean?

A: Centrifugal pumps typically have only one impeller, whereas a multistage pump has multiple impellers or stages of impellers back to back. Installing the impellers in this way allows the pump to generate much higher pressures. Multistage pumps are perfect for applications that require higher pressures or a combination of high pressure and low to medium flow rates.

Q: Can this pump run dry?

A: No, definitely not! multistage pumps will incur damage even after short periods of dry running. The mechanical seal will be destroyed, and this will cause the pump to leak. There is also the possibility that the motor will burn out. Our advice is to ensure that the pump has a flooded suction or always make sure that the pump casing and inlet pipe are filled with water; one way of ensuring this is to fit a check valve on the inlet line to stop water escaping when the pump is inactive.

Q: How do I know what pump materials are correct for my application?

A: Firstly, always check the compatibility of the materials available against the fluid being pumped. The main materials to check are the pump casing, impeller, o-ring and mechanical seal. It may be that more than one material is suitable for your fluid and selection could be based on the application type.

Q: How does a multi-stage pump work?

A: Multistage pumps are defined as pumps in which the fluid flows through several impellers fitted in series. The head of a single-stage centrifugal pump is largely governed by the type of impeller and the circumferential speed.

Q: Why do you have to be careful when trimming the impellers on a multistage pump?

A: Trimming involves machining the impeller to reduce its diameter. Trimming should be limited to about 75% of a pump's maximum impeller diameter, because excessive trimming can result in a mismatched impeller and casing.

Q: What is the efficiency of a multistage pump?

A: Multistage pumps designed with optimal clearances, impeller trimming, and minimized friction losses provide the best efficiency. Look for pumps rated over 80% efficiency at the operating point. Higher efficiency translates to lower energy consumption and operating cost over the pump's service life.

Q: How efficient is a multi-stage heat pump?

A: The results indicate that the three-stage super heat pump with appropriate mixtures is up to 27.3% more energy efficient than the conventional single-stage system with pure fluids.

Q: What is the formula for multistage pump?

A: Because the power of the multi-stage pump N (KW) = head (m) × flow (m3 / s) × 1000 (weight of water Kg / m3) ÷ 102 (power conversion factor) ÷ η (efficiency of multi-stage pump), by This can seek the efficiency of multi-stage pumps.
