XWAM4G40N-SX | 4 GPM 4000 PSI Pump Left Hand 24mm Shaft Drive

XWAM4G40N-SX Annovi Reverberi Triplex Plunger Pump

The XWAM4G40N-SX is a high-pressure triplex plunger pump designed for commercial and industrial systems requiring reverse rotation compatibility. Delivering 4.0 gallons per minute at 4,000 PSI, this pump is optimized for maximum cleaning power in compact setups where a left-hand shaft drive is essential. With its 24mm solid left-hand shaft and 1,750 RPM operating speed, the XWAM4G40N-SX ensures seamless integration into reverse-drive systems without compromising performance.

Built for heavy-duty applications, this pump features ceramic plungers, industrial-grade seals, and stainless steel valves that provide long service life under continuous-duty cycles. Whether for contractors, mobile cleaning systems, or fleet operators, the XWAM4G40N-SSX is engineered to withstand the most demanding environments.

Built for Reverse Rotation Systems

Unlike standard right-hand shaft pumps, the XWAM4G40N-SX is specifically engineered with a left-hand solid shaft to meet the needs of reverse-drive installations. Its triplex plunger design delivers smooth, pulsation-free flow, minimizing strain on hoses and reducing wear on downstream components. Ceramic plungers, premium seals, and stainless valves ensure durability while maintaining consistent 4,000 PSI performance.

How the Pump Works

The XWAM4G40N-SX utilizes a triplex plunger system in which three ceramic plungers compress incoming water through stainless steel valves to produce a steady output of 4 GPM at 4,000 PSI. Its reverse rotation capability allows integration into non-standard equipment layouts, while the 1,750 RPM operating speed ensures balanced performance, reduced vibration, and minimal wear.

The oil-bath crankcase, equipped with a sight glass and a vented dipstick, keeps internal components lubricated and simplifies routine maintenance, ensuring long-term reliability in high-pressure cleaning operations.
