Graco Paint Sprayer Pump 233480 Cart 5 gal 1pc

These paint sprayer pumps dispense paint using the pressure generated by diaphragms that push back and forth on each other, creating suction to pull the paint into the pump and pressure to push the paint out of the sprayer. They must be paired with a spray gun to atomize the paint and often deliver high volumes of paint at lower pressures than other sprayers.
