Hose pump, also known as peristaltic pump, can transport a variety of temperatures not higher than 100 ℃ of the liquid material, especially suitable for transporting some high-viscosity, high solid content, highly corrosive materials, as well as some of the larger solid particles containing longer fibers, or for the shear more sensitive materials. Widely used in metallurgy and mining, chemical industry, environmental protection, agriculture, tunnel engineering machinery, food, medicine and other industries.

How Hose Pumps Work

Hose pumps are sometimes also called peristaltic pumps or squeeze pumps. Inside the hose pump, there is a hose, which is fed in a U-shape through the housing. To convey liquid, the pump hose is clamped by rollers, which turn on a rotor: The rotor’s movement causes the clamped point to move along the hose. The medium inside is thus conveyed through the inside of the pump hose from the intake side to the pressure side. So hose pumps belong to the positive displacement pumps.
