Centrifugal Pump Guide


Here at TS Pumps, we supply a wide range of Centrifugal Pumps that are suited to a variety of installations, including industrial and hygienic applications. For larger industrial applications, such as waste removal, and purification, we recommend checking out Salvatore Robuschi Centrifugal Pumps.

We also have a range of smaller Centrifugal Pumps that include Hygienic, Industrial, Self-Priming and Vertical Immersion Centrifugal Pumps. Click here to view the full range of Industrial Centrifugal Pumps.

What is a Centrifugal Pump?

A Centrifugal Pump is an extremely versatile type of process pump that transfers fluid via an impeller mechanism.

How does an Industrial Centrifugal Pump work? How does a Centrifugal Pump work?

Standard Centrifugal Pumps are not self-priming, and those that are have an extra component built-in. Therefore, standard Centrifugal Pumps require their casing to be filled with liquid before they can be started, which allows the pump to have a positive suction head ensuring that the pump operates efficiently.

Keep reading for information on Self-Priming Centrifugal Pumps which we can also offer!

When the pump starts, the liquid within the pump enters the pump casing at the eye of the impeller. As the impeller rotates, it generates a centrifugal force that draws your product through the pump casing, towards the discharge port. As the fluid moves towards the discharge outlet, it creates a low-pressure point at the eye of the impeller which ensures that the pumping cycle is continued by creating a suction to draw in fluid from the inlet port.


What options are available for a Centrifugal Pump?

Magnetic Driven Centrifugal Pump

Our Centrifugal Pumps are available in 3 materials:

They are also available as 2 different drive options:

Self-Priming Centrifugal Pump

Our Centrifugal Pumps are available as standard or as Self-Priming Centrifugal Pumps.

We supply 2 types of Self-Priming Centrifugal Pump, Industrial and Hygienic.

Both pumps are electrically driven, handling a flow rate up to 58 m³/hr and pressures up to 40m.

For additional details, head over to the product pages above.

Stainless Steel Immersion Centrifugal Pump Vertical Immersion Centrifugal Pumps

We supply Immersion Centrifugal Pumps in either Stainless Steel AISI 316L or PP and PVDF.

The Immersion Centrifugal Pump is an extremely reliable pump that has been manufactured with the motor above the liquid surface, meaning this pump can replace a self-priming pump.

The pump is designed without the need for mechanical seals, which are usually the source of a leak risk, or bearings which makes the Immersion Centrifugal almost maintenance-free.

Depending on the model and size of your Vertical Immersion Centrifugal Pump, the pump can handle solids up to 6mm in diameter and be submerged to a depth of 419 to 425mm.

What are the benefits of using a Centrifugal Pump?

As Centrifugal Pumps are so versatile, there is a large list of benefits that are specific to the various ranges. Below is an assortment of benefits for the pumps.


What industries and applications can a Centrifugal Pump be used for? Hygienic Centrifugal Pump

As previously mentioned, Centrifugal Pumps are extremely versatile, able to be used for a wide range of industries, for numerous applications.


Industries include:


Industries requiring hygienic applications:

How to maintain a Centrifugal Pump


Things to check:

Typically, mechanical seals in a Centrifugal Pump require very little maintenance, however, it is important to note that if there is a leakage or the pump has run dry for any time at all that we recommend replacing the mechanical seal within your Centrifugal Pump as soon as possible.

To avoid cavitation:

1. Operate the pump as close as possible to its BEP, which can be achieved through several options:

2. Reduce the fluid temperature

3. Maintain filters that are installed on the suction and discharge lines.

4. Check your product and suction pipework to ensure that they don’t contain air.




Can a Centrifugal Pump run dry?

No. Unfortunately, even running your pump dry for a short amount of time will damage the mechanical seal within your Centrifugal Pump, as well as burn out the motor. The good news is that this can be avoided by ensuring your pump has flooded suction unless your pump is self-priming. If you think dry running is a risk during the operating of your pump, we recommend a form of Dry Run protection for your pump installation.

Self-Priming Industrial Centrifugal Pump What dry run protection can we offer for centrifugal pumps?

If you are worried about your Centrifugal Pump running dry, we do offer dry run protection for Centrifugal Pumps. This is often in the form of a system within the installation that monitors the pressure of the fluid within the pump and will switch off the pump when the pressure drops. For more information, please ask the Sales team when requesting a quote.

If flooded suction isn’t ideal for your industry, head over to our Self-Priming Centrifugal Pump page.

Can a Centrifugal Pump handle solids?

Our range of Centrifugal Pumps can typically handle solids up to 6mm in diameter.

What is a Centrifugal Pump’s BEP (Best Efficiency Point)?

Failing to run your Centrifugal Pump to its BEP can cause a list of problems for your pump, including reducing the life span of your pump seals, bearings and impeller. This includes running your pump too far on either side of the BEP (too low or too high).  BEP ensures a Centrifugal Pump is running as efficiently as possible which reduces energy costs, improves pump life and lowers maintenance costs.

How do you find the Best Efficiency Point for your Centrifugal Pump?

The Centrifugal BEP is typically marked on the performance curve provided with your pump. If you need assistance finding out the BEP for your Centrifugal Pump, please contact the sales team: [email protected]

How to spec a Centrifugal Pump – What do we need?

The first piece of information that we’ll need is the application you’re pumping. We need to know exactly what you want your pump to achieve. We’ll also need to know if you’ve got any additional requirements specific to your application, such as if you require the pump to be ATEX rated (which may be needed if pumping hazardous products or the pump is situated in a hazardous environment).

We’ll also need to know the following details:
