What is a centrifugal pump
A centrifugal pump is a dynamic pump that uses a rotating impeller to increase the velocity of a liquid.
Liquid enters the pump near the centre of the impeller and is accelerated towards its outer diameter. The pump casing or diffuser then converts much of this velocity into pressure, producing continuous flow through the system.
Centrifugal pumps are particularly well suited to continuous transfer of relatively free-flowing liquids and are available in many configurations for industrial, chemical, water, hygienic and high-pressure applications.

How Does a Centrifugal Pump Work?
A centrifugal pump operates through four basic stages:
- Liquid enters the suction connection and reaches the impeller eye.
- The rotating impeller transfers energy to the liquid.
- Liquid accelerates outwards through the impeller.
- The casing or diffuser converts part of that velocity into pressure before the liquid leaves through the discharge.
Unlike a positive displacement pump, a centrifugal pump's flow is determined by the interaction between the pump curve and the system curve.
This is why centrifugal pump selection must consider the complete system rather than flow rate alone.
Why Choose a Centrifugal Pump?
Centrifugal pumps are often the preferred choice where high flow rates, continuous operation and efficient liquid transfer are required.
Key benefits include:
- High flow capacity
- Continuous, smooth flow
- Simple, reliable design
- Low maintenance requirements
- Energy-efficient operation
- Wide range of materials and configurations
- Suitable for hygienic, industrial and chemical applications
- Cost-effective for transferring low-viscosity liquids
Centrifugal pumps are especially effective when handling clean or relatively free-flowing liquids at medium-to-high flow rates.
Where can centrifugal pumps be used
Centrifugal pumps are utilised through a variety of different industries as a result of their efficiency and versatillity.
They tend to be used in the transfer of low viscosity fluids, with some of the main applications where centrifugal pumps are used include water supply and distribution systems, wastewater treatment plants as well as oil and gas, chemical processing, power generation, and food and beverage production. Centrifugal pumps tend to be ideal for processes that require a continuous and steady flow of fluids, making them a essential in a range of different processes across varyingsectors.
Applications of Centrifugal Pumps
Centrifugal pumps are used across a wide range of industries to transfer clean and low-viscosity liquids efficiently.
Water & Wastewater
Used for water transfer, pressure boosting, filtration systems and wastewater treatment processes.
Chemical Processing
Suitable for solvents, acids, alkalis and process chemicals where the correct material compatibility is selected.
Food & Beverage
Hygienic centrifugal pumps are widely used for milk, beverages, CIP systems and other low-viscosity food products.
Pharmaceutical & Biotechnology
Designed for hygienic fluid handling, cleanability and contamination-sensitive processes.
General Industry
Commonly used for cooling water, utilities, HVAC systems, boiler feed, cleaning systems and general liquid transfer.
How to select a Centrifugal Pump
Selecting the right centrifugal pump starts with understanding both the liquid being pumped and the operating conditions. Choosing the correct pump improves efficiency, reduces maintenance and helps maximise service life.
When selecting a centrifugal pump, consider:
- Flow rate – How much liquid needs to be transferred within a given time.
- Head (Pressure) – The pressure required to move the liquid through the system, including pipework, valves and equipment.
- Fluid properties – Consider viscosity, temperature, chemical compatibility and whether the liquid contains suspended solids.
- Materials of construction – Ensure the pump materials are suitable for the process fluid to minimise wear and corrosion.
- Seal arrangement – Choose the appropriate sealing solution based on the application, fluid characteristics and environmental requirements.
- Installation conditions – Factors such as suction lift, available NPSH and the installation environment can significantly influence pump performance.
If you're unsure which centrifugal pump is best suited to your application, AxFlow's engineers can assess your process requirements and recommend the most appropriate solution for reliable, efficient operation.

When Not to Use a Centrifugal Pump
Although centrifugal pumps are highly versatile, they are not the best choice for every application.
A centrifugal pump may not be suitable where:
- High-viscosity liquids require consistent flow.
- Accurate metering or dosing is essential.
- Frequent dry running may occur.
- High suction lift is required.
- Abrasive slurries or large solids are present.
In these situations, progressive cavity pumps, rotary lobe pumps, peristaltic pumps or AODD pumps may provide a more suitable solution depending on the application.
What is NPSH and why does it matter?
NPSH — Net Positive Suction Head — describes the pressure conditions at the pump suction relative to the liquid's vapour pressure.
Two values are important:
NPSHa — NPSH available
Determined by the installation and process conditions.
NPSHr — NPSH required
Associated with the pump's hydraulic design and operating point.
The installation must provide sufficient NPSH available above the pump requirement, with an appropriate engineering margin.
Poor suction conditions can lead to cavitation, unstable flow and damage.
Axial flow pumps are devices that are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an electric motor or steam turbine (in case of turbine-driven feedwater pumps).
FAQ Centrifugal Pumps
When should I choose a magnetic drive pump instead of a mechanically sealed centrifugal pump?
Magnetic drive pumps are often preferred where leakage must be minimised, particularly with hazardous, toxic or corrosive liquids. Because there is no dynamic shaft seal, they can reduce the risk of fugitive emissions. Mechanically sealed pumps may still be more suitable where solids, heat or process conditions make a magnetic drive arrangement less appropriate.
What is the difference between a single-stage and multistage centrifugal pump?
A single-stage pump uses one impeller and is typically used for moderate head requirements. A multistage pump uses several impellers in series to generate higher discharge pressure. Multistage designs are commonly considered for boiler feed, pressure boosting and other high-head applications.
How does changing pump speed affect centrifugal pump performance?
Changing rotational speed affects flow, head and power consumption. Increasing speed increases flow and pressure, but also increases absorbed power significantly. Variable speed drives can therefore be useful for matching pump output to changing process demand while improving energy efficiency.
When should I consider a double-suction centrifugal pump?
Double-suction pumps are typically considered for high-flow applications where reduced hydraulic loading and improved suction performance are important. They can be particularly useful in water transfer, utilities and large process systems where very high flow rates are required.
How can I reduce the energy consumption of a centrifugal pump?
Energy use can often be reduced by selecting a pump close to the required duty point, avoiding excessive throttling, using variable speed control where appropriate and keeping pipework losses as low as practical. Correct impeller diameter and system design can also make a significant difference to lifecycle operating cost.
