Abstract

The pump has drive rods (2) and a housing (6) with holder (5) and intake (8). The holder has a shape, which is expanded and curved outwards relative to a straight line between the fastening points (17) of the holder on the drive rods and the pump housing. The holder consists of mainly two struts (16). The pump has a spiral housing with internal rotor, and there is a cutter wheel (25) located above the pump intake in the holder area.
