With the development of various industries, the application of peristaltic pumps has become more and more extensive. Today, let me tell you about the principle of the peristaltic pump
and the peristaltic pump hose.
1. The working principle of a peristaltic punp
Peristaltic pumps are a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained within a flexible hose or tube fitted inside the pump casing. The actual pumping principle, called peristalsis, is based on alternating compression and relaxation of the hose or tube, drawing content in and propelling product away from the pump.
A rotating shoe or roller passes along the length of the hose or tube creating a temporary seal between the suction and discharge sides of the pump. As the pump’s rotor turns this sealing pressure moves along the tube or hose forcing product to move away from the pump and into the discharge line. Where the pressure has been released the hose or tube recovers creating a vacuum, which draws the product into the suction side of the pump, the priming mechanism
Combining these suction and discharge principles results in a powerful self-priming positive displacement action.
2. Peristaltic Pump Hose
Peristaltic tubing is fitted in a peristaltic pump – there the rotor with a number of rollers or shoes compresses the tubing and forces liquid or semi-liquid substances to move. Peristaltic pump tubing is made of extremely flexible rubber (natural rubber, NBR, CSM, EPDM, silicone and other), resistant to compression, friction and with an adequate level of chemical resistance. They may be textile-reinforced
The peristaltic pump hoses are specifically engineered for application on peristaltic pumps,it is designed and manufactured for long operational life and minimized cost.
