4300017 AAA Triplex Plunger Pump, 3700 PSI
The 4300017 is a pressure washer pump from AAA. This triplex plunger pump is rated at a max water pressure of 3700 PSI with a flow rate of 2.5 GPM.
AAA's 4300017 includes a fully-adjustable unloader system, an oil sight glass, and a thermal relief valve.
It also comes equipped with PowerBoost technology, which provides higher pressure at the spray nozzle in a pressure washer system.
Features of the 4300017 Pump
- The pump uses PowerBost technology, enhancing the water pressure at the power washer's spray tip.
- Comes with an integrated and adjustable unloader valve with an ergonomic design.
- Dual oversized ball bearings helps keep the pump steady while in operation, reducing damage over time.
- Built from an anodized die-cast aluminum crankcase that is corrosion-resistant.
- A durable brass pump head holds up, no matter the cleaning jobsite.
- Uses a 3/4 in. gas engine flange and hollow shaft, fits most horizontal shaft engines.

Note on Burst Pressure:
The "Burst Pressure" of a pressure washer pump is the highest pressure the pump produces when in a static position and when the trigger is first squeezed, giving the initial burst of pressure and does not reflect the actual operating pressure.
The accurate operating PSI of any pump would be determined by the engine’s horsepower and the size of the nozzle being used at the end of the wand, restricting water flow and causing back pressure.
It is possible for a single pump to be rated at various GPM and maximum PSI levels by adjusting factors such as engine RPMs, nozzle size, or engine horsepower.
