What is peristaltic pump hose ?
Peristaltic hose 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 hose 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 be textile-reinforced.
Tube： NR, EPDM, NITRILE BUNA-N, CSM, FKM
Reinforcement：two layers, four layers or six layers spiral high-tensile steel cords.
Cover：NBR rubber, black colour, smooth, cloth finish，abrasion cover is resistant to abrasion, cutting, gouging and weather.
Temperature Range： -40°C to +90°C
A smooth-wall, flexible hose is fitted in the pump casing and is squeezed between shoes on the rotor that is positioned inside the pump casing. This rotating action moves the product through the hose at a constant rate of displacement. The hose restitution after the squeeze also produces a strong vacuum effect that draws product into the hose from the intake piping. The vacuum that is created by the hose’s restitution can build discharge pressures of as much as 16 bar (232 psi) without damaging or deforming the hose, or causing it to rupture.
This style also maintains excellent volumetric consistency, making it ideal for the strict dosing and 24/7 operating cycles that can be required in many industrial applications while typically-providing suction-lift capabilities of as much as 9 meters (29.5 feet). Peristaltic (hose) pumps are also easy to operate and easy to maintain with no seats, valves, glands or mechanical seals needed, which leaves the hose as the pump’s only replacement part.
