How does it work?
It is also referred to as peristaltic hose or tube pumps, operate using positive displacement. The fluid is fed through the tubing by rollers that rotate squeezing the tube against the pump housing.
As the roller moves over and past a point on the tubing, it expands to allow more fluid to enter. During operation, at least one roller is used to close the tube, therefore the need for extra valves is eliminated.
Peristaltic pumps are ideal for corrosive and viscous fluids, as the only part of the pump to come into contact with the fluid is the flexible tubing. Depending on the model, the tubing or the head can be easily replaced, while the pump itself remains a maintenance-free component.
