Abstract (en)

[origin: EP1416158A1] The pump (1), for liquids (2) contaminated with solid matter, has at least one filter (6) in the pump chamber (4). The pump chamber has an inflow (5) and an outflow (7) valve. The pump unit (8), with a membrane (9), is moved to and fro by a push rod (10), with a radial reciprocating movement. The pump drive (3), rotating around an axis (A), is mounted within a radially variable guide contour (11), in a positive fit. The push rod rides in the guide contour in a positive fit through a roller bearing (12).
