Have You Tried a Peristaltic Pump for that Tough Application?
If you haven't tried one yet...maybe it is time. These unique pumps have been building a reputation throughout industry as the "pump for tough applications."
The basic principle of a peristaltic pump is a mechanical application of "peristalsis," a physiological term referring to the alternating contraction and relaxation of muscles around a tube (throat or intestines for example) to force the tube's contents through it. Understandably, the application of this basic peristaltic principle as a method of mechanical fluid transfer was developed in medical and biotechnology applications. A smooth wall flexible tube or hose is squeezed along its length, positively displacing the fluid contained within the tube. The tube's restitution after the squeeze creates a vacuum, which draws more fluid into the tube, creating a gentle pumping action with minimal damage to the media inside the tube, particularly when compared to other methods of mechanical transfer. Also, because the fluid is contained completely within the tube, the opportunity for contamination of the fluid is also minimal.
