XWAM7G40N-SX | 7 GPM 4000 PSI Pump 24mm Left Hand Shaft Drive

AR North America XWAM7G40N-SX Commercial

Reverse-Rotation Triplex Plunger Pump

The XWAM7G40N-SX is a commercial-duty triplex plunger pump engineered specifically
for reverse-rotation pressure washer systems. Delivering 7.0 GPM at 4,000 PSI,
it provides the high-output performance required for demanding industrial cleaning
environments while maintaining smooth, efficient operation at 1,750 RPM. Its
24mm left-hand solid shaft makes it the ideal solution for applications where a
standard clockwise pump cannot be used—ensuring compatibility with
counterclockwise engines, specialized motors, and reverse-driven industrial rigs.

Built with ceramic plungers, stainless steel valves, and heavy-duty high-pressure
seals, the XWAM7G40N-SX is designed for long service life in continuous-use
environments. Maintenance is simplified with an onboard oil sight glass, vented
dipstick, and pre-filled break-in oil. Each pump is factory-tested, verified for
flow and pressure accuracy, and backed by a 5-year commercial warranty with
U.S.-based service support.

How the XWAM7G40N-SX Works

The pump uses a high-efficiency triplex plunger mechanism in which three ceramic
plungers operate in synchronized motion to generate smooth, consistent high-pressure
water flow. Operating at 1,750 RPM, the pump maintains a balance between
steady output and reduced mechanical wear—extending seal, crankshaft, and bearing life.

Its left-hand (reverse rotation) shaft makes the XWAM7G40N-SX compatible with
counterclockwise engines, custom wash trailers, specialty industrial equipment,
and municipal cleaning vehicles that require reverse-driven systems. Ceramic
plungers minimize thermal stress, while stainless steel valves provide stable,
high-flow management under extreme pressures.
