RKV4G40H-185806 4.0 GPM 4000 PSI Pump | 3400 RPM

RKV4G40H-185806 Triplex Pump

The Annovi Reverberi RKV4G40H-185806 is a commercial-duty triplex plunger pump engineered for continuous use in
industrial wash systems, mobile pressure-washing rigs, fleet service centers, and agricultural cleaning operations.
Delivering 4.0 GPM at 4000 PSI and running at 3400 RPM, this model provides the high-pressure performance needed
for equipment restoration, facility maintenance, and heavy soil removal. Its direct-drive configuration integrates
cleanly with compatible gasoline engines, creating a compact, efficient solution where reliability and daily uptime
are essential.

Built with a brass manifold, bronze connecting rods, and solid ceramic plungers, the RKV4G40H-185806 withstands
heat, vibration, and the mechanical demands of repeated cycling in demanding environments. Hot-water compatibility
allows operators to pair this pump with heated systems for improved degreasing and sanitation performance.
