The only pumping element for the peristaltic pump is the tube, the pump works by squeezing the
tube with rollers or shoes. This means that the pump can run dry, self-prime and handle viscous or
abrasive liquids, plus, as the tube is one complete unit, there are no seals thus making the pump
leakfree and hygienic. Furthermore, because each rotation displaces a constant amount, the pump
is excellent for dosing applications. Although this principle applies to all peristaltic pumps the
difference is in the head and the drives.
