Lubricant pump system with rapid coupling reservoir

A lubricant pump system comprising:

• a pump assembly including a housing with a central axis, an interior pumping chamber having an inlet and at least one pumping unit disposed at least partially within the pumping chamber and configured to displace lubricant from the pumping chamber through an outlet, the housing having a pump interface with an opening fluidly coupleable with the pumping chamber inlet and a pump valve controlling lubricant flow through the pump interface opening and including a fixed valve seat and a movable valve plug;
• and
• a reservoir including a body connectable with the pump housing and having a central axis, an interior storage chamber for containing a quantity of lubricant and a reservoir interface engageable with the pump interface, the reservoir interface including an opening fluidly coupleable with the storage chamber and fluidly coupleable with the pump interface opening, the reservoir body having a reservoir valve controlling lubricant flow through the reservoir interface opening and including a fixed valve seat and a movable valve plug, the reservoir valve plug contacting the pump valve seat and the reservoir valve seat contacting the pump valve plug when the reservoir interface engages with the pump interface such that relative displacement of the reservoir toward the pump assembly displaces both the reservoir valve plug and the pump valve plug generally along the central axis and fluidly couples the reservoir storage chamber with the pumping chamber.
