A squeeze pump comprising: a casing having an arcuate inner peripheral surface; a resilient tube bent arcuately in the casing and having opposite ends projecting outwardly from the casing through openings therein; a rotary shaft disposed in an axis of the casing; and at least a pair of squeezing means mounted on the rotary shaft in the casing, the squeezing means including a pair of roller shafts extending perpendicularly to the rotary shaft, and a pair of squeeze rollers rotatably mounted on the respective roller shafts and rollable on opposite side surfaces of the resilient tube and revolvable at the same time about the rotary shaft for compressing the resilient tube from opposite sides thereof to transmit slurry in the casing, each of the squeeze rollers being divided along its axis into three independently rotatable roller sections, namely, a base end roller section constituting a base portion of the squeeze roller, a distal end roller section constituting a distal end portion of the squeeze roller, and an intermediate roller section constituting an intermediate portion between the base end roller section and the distal end roller section.
