Watson Marlow Peristaltic Tube Pumps and Tubing

What is a Peristaltic Tube Pump?

A peristaltic pump operates by squeezing a point along a length of flexible tube, then moving that point towards the outlet to push the fluid within the tube in that direction. This squeezing action is created by a roller or shoe. When multiple squeeze points are introduced it creates a scenario where the fluid cannot return. These systems are usually in a 'U' shaped configuration with two pressure points attached to a rotor and must be squeezing the tube at all times. The tubing must be flexible enough to withstand the squeezing, while also returning to the original cross section area in order to provide suction for the inlet. In this manner the flow rate is proportional to the speed, and independent to the outlet pressure.

Advantages of peristaltic pumps:

The material never leaves the tube, avoiding contamination of the fluid, pump, and environment.
Accurate and repeatable flow rates
Slurries, viscous, shear-sensitive and aggressive materials can be pumped without damaging the equipment
No valves or glands to corrode or wear
Self-priming and able to run dry
Simple design, requiring significantly less components to monitor and maintain
Reversible operation

Peristaltic tube pump

Peristaltic pumps are used in various environments such as medical (Dialysis and IV delivery systems), laboratory, food and beverage, manufacturing, construction, and waste.

Peristaltic tube pumps differ from peristaltic hose pumps through the use of continuous tubing and greater flow rate accuracy.
