RKA4G30E-VRT-PKG | C-Face 182T 184T, 4.0 GPM 3000 PSI, VRT Unloader

RKA4G30E-VRT-PKG by Annovi Reverberi — Complete VRT Plumbed Triplex Pump Package | 4.0 GPM | 3,000 PSI | Forged Brass Manifold | NEMA C-Face 182T-184T Electric Motor | VRT Unloader with Easy Start | Auto-Reset Thermal Relief | Dual Stainless Inlet Filters | 12,000 Cleaning Units

The RKA4G30E-VRT-PKG by Annovi Reverberi is a complete, factory-assembled VRT plumbed triplex ceramic plunger pump package engineered for NEMA C-Face 182T-184T electric motor-driven pressure washing systems requiring 4.0 GPM at 3,000 PSI with fully integrated pressure regulation, thermal protection, and inlet filtration. Rated at 4.0 GPM and 3,000 PSI, the RKA4G30E-VRT-PKG delivers 12,000 cleaning units — combining 4.0 GPM output with 3,000 PSI cleaning force for contractor pressure washer builds, fleet wash systems, agricultural sanitation, industrial plant washdown, and municipal cleaning programs — through a forged brass manifold, solid ceramic plungers, stainless steel valves, dual redundant packing, and a direct-coupled NEMA C-Face electric motor interface that eliminates belts, pulleys, and alignment variables entirely. As part of Annovi Reverberi’s pump and unloader assemblies stocked and supported by WSHPWR, the RKA4G30E-VRT-PKG is the complete electric motor answer for operators who need 3,000 PSI with everything factory-plumbed, factory-tested, and ready to run.

The RKA4G30E-VRT-PKG is a factory-engineered, factory-assembled, factory-tested complete system — designed by Annovi Reverberi in Modena, Italy and distributed across North America by AR North America. The VRT plumbed package format means the unloader is not simply mounted — it is factory-plumbed with the bypass recirculation loop, thermal relief valve, dual stainless inlet filter screens, and garden hose adapter all connected and verified before shipment. Protected by a 5-year US limited warranty and built to be fully rebuilt rather than replaced, the RKA4G30E-VRT-PKG is a decade-of-service investment in a complete electric motor package.

Everything in One Box — The RKA4G30E-VRT-PKG Complete VRT Plumbed Package

Factory-Plumbed. Factory-Tested. NEMA C-Face Ready. Nothing Left to Source.

Open the RKA4G30E-VRT-PKG box and find a complete, factory-plumbed, electric motor-ready installation:

• RKA4G30E triplex ceramic plunger pump — factory-tested and pre-lubricated with break-in oil. Forged brass manifold, solid ceramic plungers, stainless steel valves, dual redundant packing — factory-installed and factory-verified. Direct-coupled NEMA C-Face 182T-184T electric motor interface — no belts, no pulleys, no alignment required.
• VRT3 external bypass unloader — factory-plumbed and pressure-set — the VRT3 unloader is factory-calibrated for the 4.0 GPM / 3,000 PSI duty point and plumbed into the complete bypass circuit before shipment. Smooth pressure regulation and controlled bypass from the first startup.
• Easy Start feature — at motor startup, the VRT3 bypass circuit opens and the pump starts against zero back pressure. The electric motor engages freely without hydraulic resistance. Once the motor reaches operating speed, the bypass closes and the system builds to 3,000 PSI. Easier motor starts, reduced starter stress, longer motor life.
• Exterior bypass recirculation loop — factory-plumbed — the bypass recirculation circuit is factory-assembled and connected, providing controlled water flow during trigger-off intervals and protecting the pump from pressure spikes throughout the cleaning cycle.
• Automatic Thermal Relief Valve (TRV) — factory-installed in bypass circuit — the thermal sensing pill monitors bypass water temperature continuously. When bypass water reaches 124–145°F, the TRV opens automatically — hot water exits through the relief port, and ambient-temperature supply water flows in through the dual stainless inlet filter screens to replace it. When temperature returns to the safe operating range, the TRV closes automatically. No manual reset. No intervention. Full thermal protection at all times.
• Dual stainless steel inlet filter screens — dual-stage inlet filtration intercepts debris before it reaches ceramic plungers, stainless valves, and dual redundant packing. The stainless screens also serve as the ambient water entry point during TRV thermal recovery — cool supply water flows through the filters to restore safe operating temperature in the bypass circuit.
• Garden hose adapter — standard garden hose inlet connection factory-included. Thread on the supply hose and the water connection is complete.
• Adapter fittings and mounting hardware — every fitting and fastener required for integration onto skids, trailers, wash bays, and OEM-built electric motor systems. Nothing to source separately.
• Chemical injector and suction hose — not included — the RKA4G30E-VRT-PKG delivers straight 3,000 PSI high-pressure water output. When detergent capability is required, a downstream chemical injector and suction assembly are sourced separately.
• Factory break-in oil — crankcase pre-filled. Oil sight glass and vented dipstick for ongoing monitoring.
• Operator manual and detailed service schematics — complete installation, startup, operating, and maintenance procedures with Annovi Reverberi part numbers for every serviceable component.

The VRT Plumbed Package — Why Factory-Plumbed Changes Everything

Not Just Mounted. Plumbed. Tested. Verified. Ready to Run.

The difference between a standard PKG pump and the RKA4G30E-VRT-PKG VRT plumbed package is the difference between a pump with a mounted unloader and a complete pressure management system in a box:

• Easy Start removes hydraulic resistance from motor startup — every time the motor starts, the VRT3 bypass circuit opens and the pump starts against zero pressure. The motor accelerates to operating speed freely before the system builds to 3,000 PSI. For electric motor installations where startup current and motor stress are operational concerns — this feature extends motor service life across thousands of daily start cycles over the pump’s service life.
• The automatic TRV eliminates the most common pump failure mode in electric installations — electric motor systems run continuously and silently. An operator can leave an electric-powered system in bypass for extended periods without the acoustic cues that alert a gas engine operator to the same situation. When bypass water reaches 124–145°F on the RKA4G30E-VRT-PKG, the TRV opens, vents the heat, and draws cool ambient supply water through the dual stainless inlet filters — automatically. Ceramic plungers, packing seals, and manifold integrity are protected without any operator intervention.
• Dual stainless inlet filter screens protect precision components — two-stage filtration intercepts debris at the supply line before it reaches ceramic plungers and stainless valves. In electric skid and wash bay installations where supply water quality varies, dual-stage filtration is the specification that prevents premature wear on precision pump internals.
• Direct NEMA C-Face coupling eliminates belt-drive variables — no belt tension to check, no pulley alignment to verify, no belt replacement intervals to schedule. The RKA4G30E-VRT-PKG mounts directly to any compatible 182T-184T NEMA C-Face electric motor for precise, maintenance-free torque transfer at 3,000 PSI operating pressure.
