Principle: A tube or hose is squeezed by rollers or shoes moving in a circular motion. The recovery of the squeezed hose causes product to be sucked into the pump.

Advantages: No valves, self-priming, can run dry, no crevices, no contamination, very resistant to abrasion, precise, accurate dosing to within 0.5%, and very low flow rates possible (less than 1 microlitre/minute). Easy to maintain, very low running costs if correctly selected.

We have extensive rabge of pulsation dampeners if smooth, pulse free flow is required.
