Abstract (en)

A closing device (1,1') used, for instance, in pumping thin-fluid mortar using a piston pump (7), wherein a shut-off body (2) in the open position rests on supports (6) and in the closed position abuts against a seal (4). The shut-off body is movable in a guide between the open and closed position. The guide is formed by a guiding cage of at least three bars (3, 3') whose centreline is parallel to the direction of travel of the shut-off body. Piston pump (7) for pumping, for instance mortar, under high pressure, equipped with two driven cylinders (8, 9), each comprising a closing device (1, 1') both on the inlet side and on the outlet side, and a method for pumping mortar under high pressure using such piston pump (7). <IMAGE>
