Abstract

A spray system includes a fluid source, a sprayer, a pump cylinder, a plunger, a pump motor, first and second inlet and outlet valves, a plurality of valve seals, a seal lubricant reservoir, and gravity fed seal lubricant lines. The pump cylinder is disposed fluidly between the fluid source and the sprayer. The plunger is situated within the pump cylinder and positioned by a displacement rod. The pump motor is configured to drive the displacement rod so as to reciprocate the plunger within the pump cylinder. The valve seals are disposed about the each of the first and second inlet and outlet valves. The lubricant seal lines carry seal lubricant from the reservoir to each of the valve seals.
