Motor
The motor drives the connecting rod which moves the diaphragm.
Pressure Switch
The pressure switch at the pump outlet turns the motor on and off to control paint pressure.
Diaphragm
The diaphragm is the heart of the pump. Driven by the connecting rod and motor, the movement of the dia- phragm draws paint from the suction tube and through to the outlet valve.
Priming Valve
The priming valve assists in priming the pump during startup. Turning the priming valve counterclockwise causes the paint to drain directly back into the pail through the priming tube. Turning the knob clockwise causes the paint to flow through the fluid outlet valve and to the hose, roller valve and extension.
Outlet Valve
The outlet valve has a ball check which prevents paint from flowing backwards into the pump. This helps keep an even supply of paint to the roller each time you trigger the roller valve.
Inlet Valve
As the diaphragm draws paint from the suction tube the paint passes through the inlet valve which opens to allow paint into the pump.
