RGXA4G70HN Solid Shaft Pump

The Annovi Reverberi RGXA4670HN is a heavy-duty, solid shaft triplex plunger pump designed for the most extreme cleaning, blasting, and surface preparation tasks. While most commercial pumps focus on higher flow with moderate pressure, the RGXA4670HN reverses that formula, delivering a high-pressure punch at 7000 PSI with a steady flow of 4.0 GPM. This unique balance makes it ideal for industries and contractors that require controlled, precision cleaning rather than high water volume.

Built with Italian engineering, this pump incorporates forged brass manifolds, hardened solid ceramic plungers, and precision stainless steel valves to withstand continuous high-pressure loads. The 24 mm solid shaft ensures compatibility with electric motors and custom belt-drive systems, making it a versatile solution for OEM manufacturers, contractors, and service centers who demand reliability at ultra-high pressures.

Despite its compact footprint, the RGXA4670HN carries the ruggedness of much larger industrial pumps. Weighing just 35.22 lbs, it provides the portability and mounting flexibility needed for mobile wash rigs, skid units, and custom-engineered cleaning equipment.
