Centrifugal Pump Guide

What is a Centrifugal Pump?

A Centrifugal Pump is a highly versatile pump that uses rotation through an impeller to accelerate fluid through the pump, where it flows radially outward through the pump casing, exiting into the discharge piping. Centrifugal Pumps have the ability to be used in almost any industry and for any application type, meeting all your sanitary, industrial and ATEX requirements. 

How does a Centrifugal Pump work?How does a Centrifugal Pump work?

Unlike Positive Displacement Pumps, a Centrifugal Pump moves fluid through the pump by rotating one or more impellers, thus creating a centrifugal force that draws fluid into the pump and out to the discharge pipe. One of the advantages of these pumps is the Centrifugal Pump impeller can be changed depending on your requirements. The full range of impeller types includes open, semi-open and closed impellers.

Tapflo UK’s Centrifugal Range includes pumps from some of the best manufacturers around the world such as BBA Pumps, Pomac and Salvatore Robuschi

Centrifugal Pump Applications

As mentioned, Centrifugal Pumps can be used in a wide range of sectors for a variety of applications, some of the most common applications we supply for include (but are not limited to):

  • Wastewater Treatment
  • Surface Conditioning
  • Food & Beverage
  • Pharmaceutical
  • Cosmetics
  • Heavy-duty industrial applications

Advantages of using a Centrifugal Pump

  1. Versatile – Centrifugal Pumps come in many different shapes and sizes. This means they can handle a variety of installations and requirements, whether you need your pump to be driven electrically or magnetically, to self-prime, to be able to handle sanitary fluids or to be big enough for large industrial applications. Whatever you require, we’ve got the answer in our range. Each product page incorporates a list of applications that the pump can handle.
  2. Fewer parts – Tapflo Centrifugal Pumps have been designed with fewer parts to troubleshoot and maintain pumps quickly and efficiently; in some cases, our Centrifugal Pumps are maintenance-free! This means less downtime for your pump and your business back up and running in no time.
  3. Efficient – Centrifugal Pumps have a higher efficiency point compared to pneumatically driven pumps such as a Diaphragm Pump. They also have a higher flow rate than most Positive Displacement Pumps for an efficient pumping solution. If your pump isn’t running efficiently anymore, get in contact with Tapflo today to see what we could do for you.
  4. Certifications – Our Centrifugal Pumps can be supplied with ATEX certification for those pump installations in hazardous areas. Additionally, for those pumps being used for hygienic applications, we provide FDA approved pumps with FDA approved seals.
  5. Easily Modified – It is very easy for us to modify our Tapflo Centrifugal Pumps to your exact requirements due to the modular design of our pumps. This means additional accessories such as heating jackets, self-priming chambers and hygienic shrouds can be added to your pump to achieve the perfect pumping solution for you. The modular design of these pumps means that you don’t necessarily need to replace the whole pump if you find yourself struggling to pump your product, for example, self-priming chambers can be retrofitted to a CT Centrifugal Pump.

Types of Centrifugal Pump

Industrial Centrifugal Pump

Industrial Centrifugal Pump

Industrial & Hygienic

Our industrial and hygienic ranges are Semi-Open Single-Stage Pumps manufactured in Stainless Steel AISI 316L. Our Hygienic Series (CTH) is manufactured with electro-polished pump casing and internals, specifically designed for hygienic and sanitary industries where cleanability and drainability are important factors, such as for food, beverage and pharmaceutical applications. Our Industrial Series (CTI) is manufactured with a glass-blasted pump casing, with a range of mechanical seal options and special executions available. This would be suited to a number of industrial applications such as water treatment, surface conditioning, chemicals, tank transfer duties and many more.


Mag Drive Centrifugal Pump

Gemme Cotti Mag Drive Centrifugal Pump

Magnetically Driven

Mag Drive Pumps are ideal for hazardous applications as they have a sealless design meaning a significantly reduced likelihood of leakage from the pump. Tapflo manufactures the CTM Pump which is a close-coupled, single-stage Magnetically Driven Centrifugal Pump, featuring either a Semi-Open or Closed Impeller. The pumps are manufactured from either glass fibre reinforced polypropylene or PVDF, offering a high mechanical and corrosion resistance. Standard Close Coupled Centrifugal Pumps operate with the impeller connected to the motor shaft directly, whereas, in our Mag Drive Pumps, the torque from the motor shaft is transmitted to the impeller by means of a magnetic coupling.

As of 2020, Tapflo has been working with Gemme Cotti, an Italian manufacturer of Magnetically Driven Pumps. We can offer their Mag Drive Centrifugal Pump as a medium to a heavy-duty alternative to Tapflo’s CTM Pump which is ideal for low to medium-duty applications.

BBA Pumps

BBA Self Priming Centrifugal Pump

BBA Self Priming Centrifugal Pump



The BBA Pumps B Series is an Industrial, Electrically Driven Self-Priming Centrifugal Pump. The range is fitted with an open impeller, changeable wear plate and non-return valve in the suction port. These pumps are easily maintained and have minimal spare part costs, and offer 2-Pole and 4-Pole options, reaching max flows up to 21 m3/hour for use in industries such as construction, wastewater management, irrigation and agriculture.



Salvatore Robuschi

Salvatore Robuschi Close Coupled Centrifugal Pump

Salvatore Robuschi Close Coupled Centrifugal Pump

Robuschi’s range of Industrial Centrifugal Pumps is ideal for large industrial applications such as handling wastewater, distillation and purification. Within their centrifugal range, we also supply Vertical Immersion Centrifugal Pumps, specifically designed for the transfer and circulation of various fluids from containers, tanks and sumps. The CTV range can, in many cases, replace a Self-Priming Pump due to the Immersion Pump being installed vertically with the motor above the liquid surface. Our Centrifugal Immersion Pumps are suited to a variety of applications, most commonly used for surface treatment, water treatment, heat exchangers and waste disposal


Pomac Sanitary Range

Pomac Sanitary Centrifugal Pump

Pomac Sanitary Self Priming Pump


Pomac’s Sanitary Centrifugal Pump range is EHEDG compliant and manufactured from stainless steel AISI 316, as are all of Tapflo’s sanitary pumps. Pomac’s pumps are ideal for the food and pharmaceutical industries or CIP processes that need bacteria to be kept to a minimum. Available standard or self-priming, the range offers high-pressure casing, a balanced stub shaft design and an optional heating jacket.


Hygienic Centrifugal Pump with Shroud

Hygienic CTX High Performance Pump
