A high pressure fluid forcing pump having a cavity adaptable for receiving an impeller assembly rotatable within the cavity of the pump. The impeller assembly includes an impeller engaged between first and second spaced apart bearing plates and having tips fixed to the bearing plates adjacent an outer circumference of the bearing plates. The impeller includes a locking arrangement that ensures that the impeller rotates about a motor shaft of the pump. The shaft is positioned in the cavity of the housing, wherein the rotational axis of the shaft and impeller are offset from the longitudinal axis of the cavity and first and second bearing plates.
