About this product
The EW4040 AAA Pressure Washer Pump, manufactured by Simpson in Italy, is a robust gasoline-powered water pump. It delivers 4.0 GPM at a high 4400 PSI and features a 1-inch hollow shaft. Weighing 20 lbs, this gray pump is compatible with cold water pressure washers from brands like DeWalt, Simpson, Delco, and Ex-Cell, and requires no assembly, offering a powerful and convenient replacement.
Our take
This AAA EW4040 pump from Simpson is a serious piece of equipment for gasoline-powered pressure washers. The 4.0 GPM and especially the 4400 PSI make it suitable for incredibly demanding cleaning tasks, easily stripping away tough grime. The 1-inch hollow shaft suggests durability and compatibility with powerful engines. It's a significant investment at $389.90, but the Italian origin and high performance specs back that up. The 'no assembly required' aspect is a nice bonus, getting you to work faster, though the California Prop 65 warning is always something to be aware of.
