Abstract

The technical field of the invention is solids-handling pumps. Here, the invention deals with the delivery plunger (5, 6, 6a, 8), which is arranged detachably (9) on the front end of a plunger rod (10) axially displaceable via hydraulic drive. An annular plunger body (5) is mounted on a basic plunger body (6, 6a) via elastic compensating elements (3a, 3b, 7a, 7b) in such a way that axial inclined positions and parallel displacements of the plunger rod (10) are permitted without impairing the peripheral sealing actions (2) of the plunger. <IMAGE>
