WH32-330SR  China made low price single roller hose pump for food and beverage, different with foreign press shoe structure, single roller design reduce number of hose squeezing, extend the hose service life. Usually single circulation flow is larger than conventional press shoe design.

When the rotor unit drives single roller to rotate, hose is squeezed and deformed. After the roller rotate, the deformed hose recover by its elasticity. Thus the negative pressure in this hose is generated, sucking slurries, and discharging through output under rollers' push, finally forms pressure conveying of slurries.
