Peristaltic Pumps are the “go-to” pump for handling highly viscous, corrosive and abrasive fluids. They have a simple design but can be customized to provide precise fluid flow to many important applications. Many of our Peristaltic Pumps are sold to OEM companies to incorporate into their medical and bio-science equipment, used in water treatment systems, used in printing products, or used for fluid testing in laboratories. But how do Peristaltic Pumps actually work?
Peristaltic Pump Process
- The Peristaltic Pump is a positive displacement pump where a flexible tube is fitted inside a pump casing
- Inside the pump casing is a central rotor with a number of rollers (lobes) attached
- When connected to power, the rotor turns and the rollers compress the flexible tubing
- Because of the design of the rollers, part of the tube will be under compression and part of the tube will be in a natural state
- As the tube is under compression, the fluid is pumped through the tube
- As the tube is in its natural state, the fluid is free to flow into the tube because a vacuum has been created
- This process is repeated, which pumps the fluid through the entire length of the tubing
This process is extremely efficient and we can see it working in our natural world. The process of peristalsis is used in our own gastrointestinal tract.
