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
- Features a hose as the only component in contact with the fluid, minimising the risk of contamination
- Classified as Positive Displacement Pumps for accurate and consistent fluid transfer
- Suitable for low and high-pressure 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
- Capable of achieving high outlet pressures of up to 15 Bar, making these pumps well suited to industrial applications
- Suited to handling low and high viscous, pure, neutral, aggressive or abrasive liquids, as well as those containing gases or solids
- Sealless design, enhancing your pump’s performance and longevity
- Hose selection based on your application
- 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
Clean in Place (CIP) Capability:
