Pressure Washer Crankshaft 1507 (3450)

It converts the motor's rotary motion into the reciprocating movement that drives the ceramic plungers and creates high-pressure water. Typical 3450 PSI commercial pressure washers use a 3.7–5 HP motor with a triplex pump operating around 1450–2900 RPM. � Metro Equipment +1 If you need a replacement crankshaft, the exact part depends on the pump model, not just the pressure rating.
