Abstract

Abstract A pipe connecting device for a submersible pump by which the connection of a submersible pump with a liquid delivery pipe can be made and adjusted in a simple operation with use of adjusting screws and setting arms thereby eliminating the discrepancy in the joint faces to be caused by the deformation or wear of the pumping apparatus. Thus, the pumping efficiency is kept undiminished even after long hours of use.
