Hose pumps come in various designs, depending on the method of hose compression:
Slipper-type design (slipper-type hose pump). The hose is U-shaped or arc-shaped within the pump chamber; two or more slippers (sliders) are fixedly mounted on a rotor (arm), compressing the hose in a sliding manner. The rotor compresses the hose two or more times per revolution (depending on the number of slippers). This sliding compression method causes the most damage to the hose, similar to a high-speed vehicle suddenly braking and sliding forward, resulting in significant damage to the tires and road surface. Because of the large amount of frictional heat generated, about half of the pump chamber is filled with lubricant to ensure normal operation. This is partly to reduce the coefficient of friction, but more importantly, to transfer the generated frictional heat to the pump body and expel it from the pump, ensuring normal operation. This slipper-type design severely limits the pump speed. This type of hose pump requires higher starting and operating torques, necessitating a more powerful motor, which means higher energy consumption. However, its advantage is that it can achieve higher outlet pressures (up to 1.6 MPa).
