PURPOSE:To lessen the fatigue of an elastic tube at the start and end of squeeze, by constituting the elastic tube so as to cause it to be pressed from both sides with press rollers, while attaching an elastic member to the nose of each press roller. CONSTITUTION:Paired press rollers 15 trundle over an elastic tube 5 while pressing it tight from both sides and successively another paired press rollers 15 also trundle over the elastic tube as they press it tight from both sides at a position behind 180 deg. away from the predecessor rollers 15. Therefore, with this, slurry in the tube 5 is continuously discharged out in the rotational direction of the press rollers 15. In this squeeze pump, as an elastic member is attached to the nose of each press roller 15, the impact of each roller against the tube sides becomes softened at the time of both start and end of squeezing. |
