Abstract

See full text

A rotary piston pump for the delivery of liquids and for the delivery of liquids containing solids. The rotary piston pump includes a pump housing which is provided with an inlet and an outlet. The pump housing includes a lining. Disposed in the pump housing, or inside the lining, are at least two counter-rotating rotary pistons, which form pump spaces during their rotation. During the rotational movement, the rotary pistons are sealed against one another, against the pump housing and against the lining. Disposed in the pump housing and/or in the lining, in the spatial vicinity of the inlet and/or the outlet, are means with which the pulsation can be reduced or even completely prevented.
