Hose pumps are self-priming rotary positive displacement pumps that operate on the peristaltic principle. The pump consists of three major parts: hose, housing and rotor. The hose is placed in the tubing bed—between the rotor and the housing—where it is occluded (squeezed).

The rollers or shoes on the rotor move across the hose, pushing the fluid. The tubing behind the shoe or roller recovers its shape, creating a vacuum and drawing fluid in behind it. A pillow of fluid is formed between the rollers specific to the interior diameter (ID) of the hose and the geometry of the rotor. Flow rate is determined by multiplying speed (rpm) by the volume of the pillow. This pillow volume is consistent, even under a wide range of viscosities.
