Introduction:

Hose pump belongs to peristaltic pump, is a positive displacement pump used for pumping a variety of fluids. The fluid is contained within a flexible tube fitted inside a circular pump casing. A rotor with a number of shoes attached to the external circumference of the rotor compresses the flexible tube. As the shoes turns, the part of the tube under compression is pinched closed (or "occludes") thus forcing the fluid to be pumped to move through the tube. Additionally, as the tube opens to its natural state after the passing of the cam ("restitution" or "resilience") fluid flow is induced to the pump. This process is called peristalsis and is used in many biological systems such as the gastrointestinal tract. Typically, there will be two or more rollers occluding the tube, trapping between them a body of fluid. The body of fluid is then transported, at ambient pressure, toward the pump outlet. Hose pumps may run continuously, or they may be indexed through partial revolutions to deliver smaller amounts of fluid.

Working Principle:

Features:

1. No contamination. Because the only part of the pump in contact with the fluid being pumped is the interior of the tube, it is easy to sterilize and clean the inside surfaces of the pump.

2. Low maintenance needs. Their lack of valves, seals and glands makes them comparatively inexpensive to maintain.

3. They are able to handle slurries, viscous, shear-sensitive and aggressive fluids.

4. Pump design prevents backflow and syphoning without valves.

Applications:

Widely used in water treatment, mineral processing, chemical industry, food industry, pharmaceutical, paint and pigments industry, agriculture & biogas, paper mills and so on.
