More pressure, more flow, and twice the hose
The YP4035PWC runs 4,000 PSI at 3.5 GPM. The flow figure is the one to watch: pressure decides whether dirt lets go, but gallons per minute decide how fast you rinse it away. Going from 2.5 to 3.5 GPM cuts real cleaning time by more than the pressure jump does.
The AAA Triplex pump here uses a bolt-on unloader, which Yanmar rates as delivering the highest nozzle pressure in its class. Practically, a bolt-on unloader is also serviceable on its own rather than requiring a pump teardown.
Set up for bigger jobs
It ships with 50 feet of 3/8-inch steel-braided Monster hose, double the YP3625PWC, so you can work a building or a machine without dragging the unit behind you. The polyurethane jacket is rated up to three times more abrasion-resistant than rubber and stays flexible in cold weather.
A 31-inch spray lance gives extra reach for siding, high equipment, and undercarriages, and five nozzles are included (0, 15, 25, 40 degrees, and soap).
