No-Clog Peristaltic Hose Pumps For Where Other Pumps Fail

Have you ever been told you're pumping a "difficult fluid" and that's why your spare parts bill is high? Are your engineers forever tending to your pump because it has clogged up or started leaking? Or maybe you just aren't getting the duty you required from it? If the answer is yes, consider a peristaltic pump - the solution for where others fail. The beauty of the peristaltic hose pump design is that its only wetted part is the internal tube - with no seals to wear, impellers to damage and no valves to clog, it's a low maintenance solution for even the harshest of applications, hazardous of chemicals and abrasive of fluids. So, if you're ready to say goodbye to dry running damage, frequent downtime and high spares costs, then we have a peristaltic pump solution for you, whether it's for solid laden food stuffs, viscous waste slurries or aggressive chemicals. Contact our pump experts today who will help specify the peristaltic hose pump for your application.

FAQs

Peristaltic pumps are part of the rotary positive displacement pump family. They are made up of just two components; a rotor that has a number of rollers or a "shoe" attached and a flexible internal hose/tube fitted inside a circular pump casing. As the rotor turns, the attached rollers compress the tube where the fluid is contained, and that continuous motion forces the liquid from the pump's inlet to its outlet.

The key difference is the component attached to the pump’s rotor which compresses the hose as the rotor turns. Roller peristaltic pumps generate less friction with up to 30% less power consumption and a lower starting torque for a smoother operation and easily adjustable speed. Shoe peristaltic pumps offer higher pressure capabilities for more heavy duty requirements.

The beauty of the peristaltic pump design it it's single wearing part; the inner hose. Whilst other pumps have seals, impellers, bearings, gaskets and coupling bushes to maintain over time, peristaltic pumps only have to replace the inner hose. This combine with the absence of a mechanical seal means that they can also run dry indefinitely without risk of damage.

Ensuring compatibility with the fluid being pumped is a vital part of peristaltic pump specification to avoid swelling, erosion and even melting of the inner hose. Our Boyser peristaltic pumps are available with Natural Rubber, NBR, EPDM, Norprene, Tygon and Hypalon hoses. Upon disclosure of the fluid you are handling we will establish the best solution.

Peristaltic pumps excel in challenging applications thanks for their ability to handle high pressure, dry running, large or clogging solids, high viscosities, shear sensitive fluids and aggressive chemicals.

Yes. The inner hose, which is the only part that comes into contact with the fluid, is available in food grade materials including NBR.

One of the great features of the peristaltic design is its ability to run dry without damage. This can give peace of mind when being used unmanned or to empty a tank or container.

Yes, peristaltic hose pumps have excellent suction capabilities without need for a manual priming device.
