HWH series peristaltic hose pump consists of pump shell, rotor, roller, idler, extrusion tube, and transmission device. The extrusion hose in the pump chamber forms a U-shaped structure, which is deformed when the rotor drives the roller to rotate. With the rotation of the roller, the hose returns to its original state due to its elastic recovery. Negative pressure is formed in the hose so that the mud is sucked in and discharged through the outlet under the action of the roller, and finally, the pressure transportation of the mud is realized.
