Peristaltic pump, also known as roller pump which is applicable for varied fluids is another variety of positive displacement pump. A circular pump casing stores the fluid in a malleable tube which is appointed inside the circular pump. Peristaltic pump works on peristalsis technique, read in brief about peristalsis technique.
Benefits Of Peristaltic Pumps
No contamination :-Contamination of the pump is prevented because the inner surface of the pump which is mostly in contact with liquid, is easy to clean or sterilize.
Minor maintenance required :- Peristaltic pumps do not have valves, seals and glands which require heavy maintenance. Hence, lack of such things make them low maintenance pumps.
Easy operation :- These pumps can manage slurries, viscous, sensitive as well as harsh liquids and their design is such that even without valves they keep away backflow and syphoning.
