Peristaltic Pumps are a versatile Positive Displacement Pump renowned for their self-priming capabilities up to 9.8 meters and pressure up to 15 Bar. These pumps perform across various industries including; Food & Beverage, Pharmaceutical, Cosmetic, Wastewater Treatment and Chemical processing.
From how they work to where they excel, this post covers the key features of Peristaltic Pumps, what to consider when selecting the right one for your application, and the range we offer.
Operating Principle of Peristaltic Pumps
Peristaltic Pumps operate on the principle of either two shoes (for high-pressure applications) or rollers (for low-pressure applications) rotating on a wheel inside the pump. This rotation compresses an internal hose, propelling a specified quantity of fluid. The hose’s ability to return to its original shape ensures consistent fluid flow, resembling the natural peristalsis process. This design allows a variety of media to enter and pass through the pump, making it an efficient choice for various applications.
Key Features of Peristaltic Pumps
- Safe and Hygienic: The hose is the only component in contact with the fluid, minimising the risk of contamination
- Accurate and Consistent: Classified as a Positive Displacement Pump
- Suitable for Low and High-Pressure: Applications including transfer, metering and dosing applications, making Peristaltic Pumps some of the most versatile pumps on the market today
- Self-Priming: Up to 9.8m, reducing the need for external priming systems
- High Outlet Pressures: Up to 15 Bar, making these pumps well suited to industrial applications
- Versatile: Peristaltic Pumps can handle a range of viscosities and media, including pure, neutral, aggressive or abrasive liquids, as well as those containing gases or solids
- Sealless Design: Enhancing your pump’s performance and longevity
- Bespoke Hoses: Hose selection based on your application
- Consistent: Shape-retaining hose design, meaning it can retain consistent fluid quantity and flow
Factors to Consider when Purchasing a Peristaltic Pump
Pressure:
Tailoring the pump selection to your application’s pressure requirements is crucial. For pressures up to 4 Bar, the PTL Peristaltic Pump is recommended, while the PT Peristaltic Pump is better suited for applications exceeding 4 Bar.
Type of Hose:
The choice of hose is critical for optimal Peristaltic Pump performance. Tapflo UK offer a range of high-quality hoses, each catering to specific applications as follows:
- NR – Natural Rubber (white marking): Most flexible, high abrasion resistance
- NR Food – Natural Rubber certificate CE 1935-2004 and FDA-Approved (black or white inside): Appropriate for the food industry
- NBR – Nitrile Buna (yellow marking): Appropriate for oils, greases and polymers
- NBR Food – Nitrile Buna certificate CE 1935-2004 and FDA-Approved (black or white inside): Appropriate for the food industry
- EPDM – Ethylene Propylene Diene Monomer (red marking): High chemical resistance
- HYPALON/SYNTHETIC RUBBER – Chlorosulfonated Polyethylene (blue marking): High chemical resistance to fluids like sodium hypochlorite, chromic, nitric and sulfuric acids
- VITON/FKM (purple marking): high chemical resistance, especially to solvents, lubricants, petrol and fuels. Good temperature resistance

FAQs
Are Peristaltic Pumps known as any other names?
Yes, Peristaltic Pumps are also known as Hose Pumps, Tubing Pumps or Rolling Pumps. They are all the same and can be used by different names by different people.
‘Peristaltic’ comes from ‘Peristaltis’, which refers to the contraction of muscles in the human intestines that moves food along; this is similar to the mechanism of this pump.
For additional FAQs, see individual FAQ pages
Can Peristaltic Pumps be run continuously?
Yes, Peristaltic Pumps can be run continuously. They have multiple different duty points, whether continuous, intermittent or occasional
For additional FAQs, see individual FAQ pages
Can Peristaltic Pumps Dry Run?
Yes. Unlike many pump types, a peristaltic pump can run dry without damage because only the tubing contacts the fluid.
