Abstract
A lubricant pump system includes a pump assembly which has a housing with an interior pumping chamber having an inlet. At least one pumping unit is disposed at least partially within the pumping chamber and is configured to displace lubricant from the pumping chamber through an outlet. The housing has 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. A reservoir includes 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 includes an opening fluidly coupleable with the storage chamber and fluidly coupleable with the pump interface opening. The reservoir body includes a reservoir valve controlling lubricant flow through the reservoir interface opening.
