Rotation pump, particularly combined submersible-flat suction-rotation pump, has pump housing with centrally arranged pump inlet opening and pump outlet opening

摘要

The rotation pump (1) has a pump housing (2) with a centrally arranged pump inlet opening (4) and a pump outlet opening. Multiple guide surfaces are partially inclined to the circumferential direction for height adjustment of an adjustment crown (3). The guiding burls supported by the guide surfaces are arranged such that a relative rotation between the pump housing and the adjustment crown causes a change in the ground clearance.
