Carotek offers Peristaltic Pumps - perfect for products that you "squeeze" through your processing system.
We are a distributor for Pulsafeeder's Periflo.
How do Peristaltic Pumps Work?
Rollers or shoes in a peristaltic pump compress the tube or hose as they rotate, creating a vacuum which draws fluid through the tube.
Nothing but the pump tube or hose touches the fluid, eliminating the risk of the pump contaminating the fluid, or the fluid contaminating the pump. The animation shows fluid being drawn into a pump tube, trapped by the pump head roller, and expelled when the next roller passes over the tube. As the rollers rotate, a vacuum is formed in the tube, pulling in more fluid, for the next roller pass.
The complete closure of the tube when it is occluded (squeezed) between the roller and the track, gives the pump its positive displacement action, preventing backflow and eliminating the need for check-valves when the pump is not running.
Peristaltic pumps have no valves, seals or glands, and the fluid contacts only the bore of the hose or tube. Simple to install, easy to use and quick to maintain, they are the hot new technology and the world's fastest growing pump type.
- There is no contamination of the pump or the fluid
- Ideal for slurries, viscous, shear-sensitive and aggressive fluids
- No backflow, no siphoning
- Wide range of tubes includes industrial, food-grade and medical
