pump housing for an eccentric helical pump and eccentric helical pump equipped with the same

摘要

The present invention relates to a pump housing (10) for an eccentric helical pump (100) comprising a longitudinal axis (1) and an axially extended hollow space (h) formed between an opening (a) in the drive side, and an opening (p) on the pump side, with the opening (p) on the pump side being closed by a main housing body (12) and a cover (14) removably attached thereto wherein the main casing body (12) has a circle segment axial guide surface (f) opposite the cap (14).
