Peristaltic pump is a mechanical device in which pressure is created by the action of squeezing along a flexible tube which pumps out a variety of fluids, very similar to peristalsis in living organism. A flexible tube situated inside a rounded pump casing contains the fluid. This constriction or squeezing action is obtained by putting the tube under compression with a roller. The pump consists of a rotor with a number of rollers which turns, and as a result, the compressed part of the tube occludes, thus forcing the fluid to be pumped off the tube.
Functioning of Pumps
The functioning of the pumps is based on the reduction of volume and relaxation of tubes, thus drawing fluids into the tubes which is quite similar to the biological functioning of throats and intestines .The contents to be pumped in Peristaltic pumps is contained inside the tube or hose, and it does not comes in touch with any operating part. These are very suitable pumping action which contributes in making the pumps suitable for accurate pumping. The high pressure tubes have both the inner and outer layers which ensure high pressure and suction boost than the tubing which is not so strong.
Utilities of Such Machines
These pumps ensure effective pumping solutions at times when the pumped products are abrasive and sticky. As the only maintenance item in the pump is the tube with no valve makes it inexpensive. Its tender pumping action makes it ideal for sear fragile items like polymers etc. As the only part of Peristaltic pumps is the hose which comes in contact with the fluid, it helps in sterilizing the inner surface of the pump. These are reversible pumps which are useful in clearing blockage. As the pumps are error-free, dosing the fluids never tend to backflow during its functioning.
Effectiveness of this Device
This pump uses digital system. The easily interchangeable pump heads combined with a wide range of tube sizes enable us to achieve extensive range of flow rates which is well suited to low flow rate requisition. These pumps can be used for both laboratory and industrial pumping systems. Such a pump is subject to various verification methods before they are released in the market. To ensure that the product is reliable it comes with a long period or warranty. There are some companies that have manufactured new version of peristaltic pumps which are shipped worldwide within a few days of order placement.
