Abstract:
1. An apparatus for diverting fluid, the apparatus comprising: a primary coupler configured to connect to a port of a suction-side fluid cavity of a high-pressure fluid pump, wherein the port is configured to receive a pump component and the pump component performs a pump function for the high-pressure fluid pump; a diverter fluid passage configured to divert a low-pressure fluid from the primary coupler to an auxiliary fluid delivery system; and the primary coupler further configured to connect to the pump component and communicate the low-pressure fluid to the pump component; wherein the port comprises a port fluid outlet passage that is in communication with the low-pressure fluid that is received from an internal passage of the high-pressure fluid pump and a port fluid inlet passage that is in communication with the suction-side fluid cavity, the pump component comprises a component fluid inlet and a component fluid outlet, the primary coupler comprises a coupler fluid inlet passage configured to communicate the low-pressure fluid between the port fluid outlet passage, the diverter fluid passage, and the component fluid inlet, and the primary coupler comprises a coupler fluid outlet passage configured to communicate a low-pressure fluid downstream of the pump component between the component fluid outlet and the port fluid inlet passage.
