ABSTRACT:
A housing for surrounding the impeller of a propeller pump, the housing having a gap ring disposed in a housing bore in the interior thereof, the gap ring being open at its circumference and in the uninstalled state having an outside diameter which is greater than the diameter of the bore which receives it, while in the installed state being pressed with bias against the housing bore which accommodates it due to the reduction of the ring's diameter. The gap ring of the invention which is open at its circumference advantageously reduces the cost of manufacture and assembly of gap rings for propeller pumps.
