What is a centrifugal pump?

We’ve stocked, installed and serviced centrifugal pumps across a number of industries for many years. Here we explain what they do and why they’re so useful.

One of the most common pump types, a centrifugal pump converts rotational energy (provided by an electric motor) into hydrodynamic energy in order to move liquid.

How do centrifugal pumps work?

The electric motor powers the pump’s impeller, and as it rotates centrifugal force causes water to be pushed outwards, creating a void. Water fills this low-pressure zone and pressure forces it out through spinning vanes to the discharge line.

What are centrifugal pumps used for?

Centrifugal pumps are flexible and can be used to pump many types of liquid, clean or dirty, in sectors as diverse as the commercial, industrial and scientific fields. They are often used in metering applications where precise volumes of liquid must be moved, such as in food production or laboratory processes.

What are the benefits of centrifugal pumps?

Because centrifugal pumps don’t contain drive seals, there is no chance of leaks occurring which means hazardous liquids cannot be spilled or seep into the electric motor. In addition, friction loss, wear and noise are all eradicated which ensures that the motor is as efficient as possible.

Another major advantage is the separation of the pump chamber from the electric motor by an air gap, which creates a thermal barrier and prevents heat transfer.
