How the XWAM55G40N Works

This pump uses a triplex plunger design where three ceramic plungers compress incoming water through stainless steel valves to generate a steady, high-pressure flow. At 5.5 GPM, it provides the additional volume needed for large-area cleaning, while its 4,000 PSI pressure cuts through grease, grime, and industrial buildup.

Operating at 1,750 RPM, the pump achieves balanced performance with reduced mechanical stress. The oil-bath crankcase, combined with the sight glass and vented dipstick, ensures consistent lubrication and reduces downtime caused by maintenance issues.
