ABSTRACT:
The present invention provides a pump which is capable of supplying a liquid free from worn materials and other impurities resulting from pump operation. In one embodiment, the pump includes a diverting passageway for diverting flow liquid from the main discharge opening to a gap between a cylinder and a shaft, between an impeller and a bearing and also includes a passageway for discharging the diverted flow liquid containing the worn materials from the gap during operation of the pump in which the main flow liquid is suctioned into the cavity of the pump and discharged through a main discharge opening.
