Abstract: 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 a

Abstract: A squeeze pump adapted to transfer a slurry with solid materials comprises a resilient tube at least partly curved along an imaginary circle, a rotary arbor situated in the center of the imaginary circle so that the curved portion of the resilient tube is equidistantly away from the rotary arbor, the rotary arbor being adapted to be rotated by power means, and at least one pair of pressing devices connected to the arbor for pressing the resilient tube. Each pressing device includes a support shaft extending outwardly from the arbor toward the resilient tube, and a presser roll freely and rotationally connected to the support shaft. The presser roll is formed of a main body and a tapered head. The two pressing devices face each other so that the innermost planes of the main bodies always facing each other are parallel and are spaced apart at a distance about twice as great as the thickness of the wall of the resilient tube.

Abstract: There is disclosed a squeeze pump in which a resilient tube (15) disposed arcuately in a pump casing (11) is pressed by presser rolls (25) rotatable about their own axes and about a common axis simultaneously, thereby to continuously feed the slurry contained in the tube (15). A plurality of the presser rolls (25) are provided, with the presser rolls (25) of each pair clamping the tube (15) from both sides and respective support shafts (24) for said presser rolls (25) being secured to a rotary arbor (22) serving as said common axis, said arbor (22) extending perpendicular to said shafts (24) and disposed at the center of the pump casing (11).
