A squeeze type pump that transfers slurry via an elastic tube by squeezing the elastic tube with pairs of rollers to elastically deform the tube by moving each pair of squeezing rollers. The elastic tube has an outer diameter, an inner diameter, and a thickness. A ratio of the inner diameter to the outer diameter is set within a range of 0.56 to 0.72, and the thickness is set within a range of 23 to 35 mm. The squeeze-type pump includes a cylindrical drum, wherein the elastic tube is arranged along an inner surface of the drum; a drive shaft sup- ported at a center portion of the drum; pairs of support shafts cantilevered by the drive shaft; and bearings rotatably supporting the rollers on each support shaft. The squeeze type rollers include attachment plates mounted on the drive shaft; a plurality of support arms cantilevered to the mounting plates; restricting rollers rotatably supported by each support shaft for restricting a position of the elastic tube when engaged with the elastic tube; and restoring rollers attached to the at- tachment plates for restoring the elastic tube, which was previously compressed by the squeezing rollers.
