Belt-drive cold pressure washers from Steam Jenny have a life-extending pulley system, which turns the pump significantly slower than if the pump was coupled with the engine crankshaft. Additionally, the belt absorbs engine vibration and allows the pump to be located farther away from the engine heat. They are powered by 9 or 13 hp Honda GX Series engines and have a triplex ceramic plunger pump. They are available with pressure ratings between 3,000 and 4,000 psi, and flow rates vary between 3 and 4 gpm. Thermal pump protection, an unloader valve and a high-pressure relief valve are standard. The unit will automatically shut down if a low oil level is detected. The chassis is constructed from powder-coated, durable seven-gauge steel. Units come with a trigger gun with safety lock, quick-connect nozzles with nozzle control, high-capacity in-line water strainer, gun/wand holder, hose reel mounting adapter and dual rubber isolators. 814/445-3400; www.steamjenny.com.
