What Is A Multistage Centrifugal Pump Used For? Industrial Applications and Pump Options
Are you curious if a multistage centrifugal pump is the right choice for the applications your business needs to perform day in and day out? Single-stage centrifugal pumps are some of the most commonly used pumps in the world. However, single-stage pumps have their limitations—that’s where multistage options come into play.
Multistage centrifugal pumps are capable of pumping liquids at much higher pressures than single-stage pumps. In addition, multistage centrifugal pumps are manufactured in horizontal and vertical configurations, for even greater customization based on your system and application.
If you’re interested in determining if a particular multistage centrifugal pump is the right fit for your application, one of our experts at C&B Equipment can help you determine which efficient and dependable pump that will produce the proper pressure for you.
What Is a Multistage Centrifugal Pump?
Multistage centrifugal pumps are typically employed when the application demands higher pressure than a common single-stage centrifugal pump can provide. Unlike single-stage centrifugal pumps, which have one impeller to pressurize and transfer liquid, multistage centrifugal pumps have two or more impellers to boost pressure and pump efficiency.
Within a multistage centrifugal pump, each impeller acts like a single-stage pump within a chain of pumps. As the liquid is propelled from one impeller to the next within the pump’s housing, the pressure of the liquid continuously increases as it passes through until it exits the pump.
By relying on multiple impellers to distribute the pressure-building load of the pump, multistage centrifugal pumps can generate greater power and pressure with smaller motors, using less energy.
8 Applications for Multistage Centrifugal Pumps
Multistage centrifugal pumps can be used for a wide variety of industrial applications. Common uses for multistage centrifugal pumps include:
- Boiler feedwater. Pumps feedwater into a steam boiler.
- Firefighting. Used to pressurize water to help extinguish fires.
- High-pressure cleaning. The pump creates a powerful stream of water used to clean an object.
- Irrigation. Used to pump water throughout an irrigation system.
- Reverse osmosis. Used to remove impurities from water.
- Snowmaking. Pressurizes water for use in sports and resort snowmaking applications.
- Water circulation. Adds pressure to the system to continuously circulate water.
- Water supply boosting. Increases pressure for water usage in residential and commercial applications.
Horizontal vs. Vertical Multistage Centrifugal Pumps
Multistage centrifugal pumps have two standard configurations, horizontal and vertical. The type of pump you will need depends on the liquid passing through the pump, the size of the system and your application’s pressure requirements.
Horizontal multistage centrifugal pumps
Being the most common configuration, horizontal multistage centrifugal pumps can handle a wide variety of applications. These pumps operate by pressuring the liquid as it travels horizontally through multiple impellers.
Typically, horizontal multistage centrifugal pumps can handle higher flow rates than their vertical counterparts. You can usually identify horizontal multistage centrifugal pumps by their segmented casing.
Vertical multistage centrifugal pumps
Most often used in applications that require powerful, compact pumps, vertical multistage centrifugal pumps feature impellers stacked on top of each other. With their clean, compact design, these pumps can deliver high-pressure liquid transfer with a single pump body and motor combination.
Vertical multistage centrifugal pumps are typically employed by clean water applications because of the minimal clearance around the impellers.
