A pump (P) for pumping liquids containing solids, e.g. waste water, sewage, sludge or manure is disclosed. The first opening (14), which is surrounded by a seat (22) for a rotary wheel (12), acts as an inlet when the pump is active and as an outlet when the liquids are pumped in reversed direction. The distance between the first opening (14) and the rotary wheel (12) is variable by one or more actuator(s) (10, 11) providing axial displacement of a bearing housing (7) for the rotary shaft (20) in a slide bearing (8), which extends through the pump housing (6), or by adjustment of the position of the first opening (14) and the seat (22), in axial direction in relation to the rotary wheel (12) by adjusting axial position of the first opening (14) and the seat (22) in a slide bearing, which extends through the pump housing (6). The actuators provide possibility for establishing a passage through the pump arrangement when pumping liquid in reversed direction through the pump arrangement (P) and for providing means for controlling release of items blocking the rotary wheel when the pump (P) is active. Use of the pump on a hoist of trailers or trucks for transporting liquids containing solids is also disclosed.
