PSG TECHNOLOGIES - PERISTALTIC PUMPS:
The principle of the peristaltic hose pump is based on the alternating contraction and relaxation of the hose forcing the contents through the pump and into the discharge piping.
A smooth wall, flexible hose is fitted in the pump casing and is completely squeezed between two shoes on the rotor and the inside of the pump casing.
The rotating action moves the product through the hose at a constant rate of displacement without slippage. The hose restitution after the squeeze, produces an almost full vacuum that draws the product into the hose from the intake piping. The pump casing is half-full with lubricant to cool the pump and lengthen the service life of the shoes and hose. Since the product only contacts the hose and not the internal pump components, this pumping technology is very suitable for abrasive and corrosive applications.
