ABSTRACT:
A pump for pumping viscous mixtures is disclosed. The pump comprises a cylindrical casing having a discharge outlet and a feeding opening at its top and side, for a hopper into which is charged viscous mixtures, a cylindrical tube slidably mounted in the casing for movement toward the discharge outlet for trapping a certain quantity of viscous mixture, and a piston slidably mounted in the tube for discharging such quantity of viscous mixture through the discharge outlet of the casing. The hopper is wider than the casing and tube for ease of filling the tube. The tube is advanced across the feeding opening by an advancing force which is exerted on the tube at a point above its longitudinal axis.
