As a pump without mechanical seals and valves, it is hardly susceptible to wear, according to a press release. Peristaltic pumps belong to the group of rotating displacement pumps. They have only one wearing part, the hose. The medium to be pumped is forced through the hose by means of external mechanical deformation. The hose is supported on the housing of the pump head and is clamped by rollers. The rollers rotate on a rotor. The rotation causes the pinch-off point to move along the hose, thus propelling the pumped medium. The suction vacuum is generated by the elasticity of the hose material.
