Laboratory Peristaltic Pumps for Precision Fluid Transfer

It is a type of positive displacement pump used to move fluids through a flexible tube. It works by compressing and releasing the tube in a sequence, mimicking the natural peristaltic motion seen in biological systems (like how food moves through the intestines). Looking for a pump that delivers precision, reliability, and zero contamination? Our peristaltic pumps are engineered to meet the most demanding fluid handling needs—without the hassle of complex installations.

A peristaltic pump operates using a series of rollers or shoes that compress flexible tubing, pushing fluid forward in a smooth, controlled manner. This non-contact pumping method ensures that the fluid only touches the tubing, making it ideal for sterile, corrosive, or sensitive liquids.
As the rollers rotate, they create a peristaltic motion—similar to how the human digestive system moves food—resulting in precise, low-shear fluid transfer. These pumps are widely used in medical, laboratory, food processing, and industrial applications due to their accuracy, reliability, and easy maintenance.
