RKV4G40H-D25056 4.0 GPM 4000 PSI Pump | 3400 RPM

RKV4G40H-D25056 Triplex Pump

The Annovi Reverberi RKV4G40H-D25056 is an industrial-grade triplex plunger pump engineered for high-output wash
systems that operate in demanding commercial, agricultural, and fleet maintenance environments. Delivering
4.0 GPM at 4000 PSI and running at 3400 RPM, this model provides the high-pressure performance required for
heavy soil removal, equipment restoration, and continuous-duty applications where uptime is critical.
Its direct-drive configuration pairs seamlessly with compatible gasoline engines, creating a compact,
efficient, and reliable cleaning platform.

Built with ceramic plungers, bronze connecting rods, a reinforced crankcase, and a corrosion-resistant
brass manifold, the RKV4G40H-D25056 offers the durability needed to withstand heat, vibration, repetitive cycling,
and exposure to harsh wash environments. Each pump is factory-tested under multiple load conditions —
including 150% overload — ensuring consistent performance in the field.
