RKV55G40-VRT3PKG Triplex Pump Package | 5.5 GPM 4000 PSI

RKV55G40-VRT3PKG by Annovi Reverberi — Complete Triplex Plunger Pump Package with VRT3 Unloader, Bypass, Thermal Relief Valve, and Inlet Filter | 5.5 GPM | 4,000 PSI | Bronze Connecting Rods | Brass Manifold | 3,400 RPM

The RKV55G40-VRT3PKG by Annovi Reverberi is a professional-grade complete triplex plunger pump package engineered for continuous-duty high-pressure cleaning systems requiring 5.5 GPM at 4,000 PSI. Rated at 5.5 GPM and 4,000 PSI at 3,400 RPM, the RKV55G40-VRT3PKG delivers 22,000 cleaning units — combining 5.5 GPM high-volume output with 4,000 PSI cleaning force for truck and fleet wash bays, contract cleaning rigs, construction and industrial sites, fleet maintenance facilities, agricultural and food industry washdown, and commercial pressure washing operations — through bronze connecting rods, solid ceramic plungers, a precision-machined corrosion-resistant brass manifold, oversized industrial bearings, and a complete factory-assembled VRT3 package with unloader, bypass system, thermal relief valve, garden hose inlet adapter, water filter, and mounting hardware. As part of Annovi Reverberi’s pump and unloader assemblies stocked and supported by WSHPWR, the RKV55G40-VRT3PKG arrives factory-tested and ready to install.

The RKV55G40-VRT3PKG is a true installation-ready package — not a bare pump requiring separate sourcing of unloader hardware, thermal protection, inlet fittings, and filtration. Every component ships factory-assembled and factory-tested, eliminating compatibility risk, reducing installation time, and delivering professional-grade continuous-duty performance from the first startup. Built by Annovi Reverberi in Modena, Italy — with US-based operations, a domestic parts distribution network, and dedicated technical support — this package arrives pre-filled with factory break-in oil, pressure-tested, and ready for installation. Protected by a 5-year US limited warranty and built to be fully rebuilt rather than replaced, the RKV55G40-VRT3PKG is a long-term investment capable of a decade of productive service life.

What’s in the RKV55G40-VRT3PKG Package

Everything Required for Installation. Nothing to Source Separately.

The RKV55G40-VRT3PKG ships as a factory-assembled complete package:

• RKV55G40 triplex plunger pump — factory-tested and pre-filled with break-in oil; bronze connecting rods, ceramic plungers, brass manifold, oversized bearings; 5.5 GPM / 4,000 PSI / 22,000 cleaning units at 3,400 RPM
• VRT3 unloader valve with integrated bypass system — factory-installed pressure regulation and safe water recirculation during trigger release; calibrated for the 5.5 GPM / 4,000 PSI duty point on the RKV55G40-VRT3PKG
• Thermal relief valve (TRV) — protects the pump from heat damage during extended bypass operation; factory-installed on the RKV55G40-VRT3PKG assembly

VRT3 Unloader Package — Bypass, Thermal Protection, and Inlet Filtration at 4,000 PSI

Factory-Assembled. No Compatibility Risk. No Separate Sourcing. Installation-Ready.

• VRT3 unloader with bypass system — the VRT3 assembly on the RKV55G40-VRT3PKG provides factory-calibrated pressure regulation and safely recirculates water during trigger release, protecting the pump from pressure spikes during the high-frequency stop-start cycles of commercial truck washing, fleet maintenance, and contract cleaning operations
• Thermal relief valve (TRV) — factory-installed overheat protection — at 4,000 PSI and 5.5 GPM, extended bypass operation generates significant heat. The TRV on the RKV55G40-VRT3PKG automatically vents hot water when pump temperature exceeds safe limits, protecting bronze connecting rods, ceramic plungers, and internal seals from heat damage
• Garden hose inlet adapter and water filter — the factory-included inlet hardware on the RKV55G40-VRT3PKG simplifies inlet plumbing and provides immediate debris filtration, protecting precision-machined components at 4,000 PSI from particulate contamination that causes accelerated wear
• True installation-ready package — unloader, bypass, TRV, inlet adapter, and filter ship assembled and factory-tested on the RKV55G40-VRT3PKG. Reduced setup time and eliminated compatibility risk compared to individually sourced components for high-output commercial pump installations

22,000 Cleaning Units — Industrial-Grade Output for Continuous-Duty Operations

5.5 GPM. 4,000 PSI. Bronze Rods. Oversized Bearings. Built for Professional Volume.

• 22,000 cleaning units at 5.5 GPM / 4,000 PSI — the RKV55G40-VRT3PKG delivers the highest combined output in the WSHPWR Annovi Reverberi pump package line, providing the volume and pressure required for large truck washing, heavy industrial surfaces, and high-demand contract cleaning operations
• Bronze connecting rods for continuous-duty service at 4,000 PSI — above the 3,600 PSI threshold where bronze rods are standard specification, the RKV55G40-VRT3PKG’s bronze connecting rods provide the strength, wear resistance, and heat tolerance required for sustained commercial and industrial high-pressure operation
• Oversized industrial bearings for high-load, high-hour operation — the RKV55G40-VRT3PKG’s oversized bearing assembly is engineered for the load demands of professional cleaning environments where daily high-pressure output over extended operating hours is the standard expectation
• Low-vibration triplex output at 5.5 GPM — three-piston crankshaft architecture distributes mechanical load evenly on the RKV55G40-VRT3PKG, reducing vibration and mechanical stress on downstream hoses, guns, and accessories during sustained commercial cleaning operations
