Engineered to surpass expectations, the 90039 AAA Professional Triplex Pump is highly efficient and minimizes engine load while delivering top performance. This easy-to-install pump replacement kit is for gas pressure washers* with a horizontal engine and a 1" diameter shaft, such as the Honda GX270. This pump can produce up to 4000 PSI at 3.5 GPM. The 90039 is designed with dual oversized ball bearings to reduce friction and allow for long lasting performance in the toughest cleaning environments. The 90039 features a stainless steel integrated unloader featuring our easy-start system. (*Check your pressure washer's inlet and outlet orientation to ensure compatibility)

  • Extend the life of your pressure washer: Save money by replacing your pump instead of buying a whole new power washer. This easy-to-install kit is great for power washers that can support 4000 PSI at 3.5 GPM to wash walls, sidewalks, vehicles, and more
  • Compatibility: SAE standard bolt pattern fits many gas pressure washers with horizontal engines. To ensure compatibility, be sure to match engine orientation, PSI, GPM, engine shaft diameter, and current pump inlet and outlet connection
  • Adjustable power: Pump includes PowerBoost Technology that delivers higher pressure at the nozzle for a more efficient cleaning experience; There is also a hand turn knob that lets you reduce power at your convenience for tasks that require lower pressure
  • Know when to change your oil: The sight glass and advanced oil seal technology eliminates the need for a dipstick. With visibility to the oil level and the oil itself, you can easily see when oil levels are low or if water has clouded the oil
  • Standard Connections: This replacement pump features a garden hose inlet and quick connect high pressure hose outlet; Use it with many pressure washer hoses, including Simpson Armor 41114, 41096, 41115 or Simpson Monster 41113, 41028, 41030, 41032, 41034
