Legacy WMG 1 Series Pressure Washer Replacement Pumps

Trusted by top manufacturers for their OEM builds, the Legacy series of pressure washer pumps are engineered for unmatched performance and long-lasting durability.

Years of research and development have gone into crafting a reliable pressure washer pump to handle the toughest jobs, delivering the power and reliability you demand for high-pressure applications.

Backed by a 5-year warranty, here's what makes the Legacy WMG 1 Pump a true workhorse:

  • Stronger Than Ever: A strengthened crankcase housing incorporates aluminum cross members and increased length for greater structural integrity, reducing stress and extending the operational life of the pump.
  • Robust Design: Reinforced crankcase with thicker aluminum cross members and extended length for increased strength and durability.
  • Enhanced Lubrication: Two-piece connecting rods with double-feeder grooves maximize lubrication for cooler operation and prolonged pump life.
  • High-Performance Components: Features include high-temperature U-seals, Dacromet®-coated manifold bolts for rust protection, and forged-brass heads with "deep-well-sealing" valve caps.  
  • Smooth and Efficient Operation: Precision-ground ceramic plungers and polished stainless-steel plunger rods minimize friction and withstand extreme temperatures and pressures.  
  • Premium Bearings: European-quality tapered roller bearings on both sides of the pump enable heavy loads, reduce noise, and minimize heat buildup.
  • And many more features! View the diagram for the full feature list.
