摘要

A vortex pump, especially a peripheral cyclic pump with a pump housing and having suction and pressure sockets and at least one impeller wheel (20) with scoops in its outer region and a circular channel in the upper part of a two-part housing, with an elastic wear ring (44) pressing on the rear face of the impeller wheel, where the pump is made with very wide production tolerances.
