ABSTRACT:
A squeeze type pump, which transfers slurry via an elastic tube by squeezing the elastic tube with pairs of rollers to elastically deform the tube while moving each pair of squeezing rollers. The squeeze type pump includes a cylindrical drum with the elastic tube being arranged along an inner surface of the drum. A drive shaft is supported at a center portion of the drum while pairs of support shafts are cantilevered by the drive shaft. Bearings rotatably support the rollers on each support shaft. The squeezing rollers are formed from a synthetic resin material.
