Abstract

Pumping equipment for concrete and materials of this type, comprising a ring-shaped flexible profiled cover wall, of rubber reinforced by cloth or other structure similar to that of a tire, coupled between two rigid cyclically mobile plates to approach and move away, for defining a variable volume cavity for pumping, characterized in that the upper plate forms a hopper for the material to be pumped, which can thus penetrate by gravity into the cavity of variable volume through an orifice of said upper plate; there being provided means for cyclically actuating the lower plate, and means for cyclically actuating a distributor equipment to open said hole towards the hopper and to put it in communication with the outlet conduit.
