The VRT plumbed package format means the unloader is factory-plumbed with the bypass recirculation loop, automatic thermal relief valve, Easy Start bypass circuit, and all hardware connected and verified before shipment. Protected by a 5-year US limited warranty and built to be fully rebuilt rather than replaced, the RRV35G40-VRT-PKG is a decade-of-service investment in 4,000 PSI VRT plumbed performance.

Everything in One Box — The RRV35G40-VRT-PKG Complete VRT Plumbed Package

Factory-Plumbed. Factory-Tested. Gas Engine Ready. Nothing Left to Source.

Open the RRV35G40-VRT-PKG box and find a complete, factory-plumbed, gas engine-ready installation:

• RRV35G40 triplex ceramic plunger pump — factory-tested and pre-lubricated with break-in oil. Bronze connecting rods, solid ceramic plungers, forged brass manifold, stainless steel valves, dual redundant packing, oversized crankshaft bearings — factory-installed and factory-verified. F24 SAE J609a 1″ hollow shaft for direct gasoline engine coupling. Ready to mount.
• VRT external bypass unloader — factory-plumbed and pressure-set — the VRT unloader is factory-calibrated for the 3.5 GPM / 4,000 PSI duty point and plumbed into the complete bypass circuit before shipment. Smooth pressure regulation, controlled bypass, and stable output from the first startup.
• Easy Start feature — at engine startup, the VRT bypass circuit opens and the pump starts against zero back pressure. The gasoline engine engages freely under no hydraulic load — recoil pull starts cleanly, electric starters draw minimum current. Once the engine reaches operating speed, the bypass closes and the system builds to 4,000 PSI. Easier starts on every pull. Less starter stress. Longer engine 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 continuously monitors bypass water temperature. 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 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.
• Mounting hardware and plumbing fittings — every fitting and fastener required for installation onto contractor skids, trailer frames, fleet wash bays, and OEM gas engine systems. Organized in the box.
• Chemical injector and suction hose — not included — the RRV35G40-VRT-PKG delivers straight 4,000 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.
• Operating manual and parts breakdown — complete installation, startup, operating, and maintenance procedures with Annovi Reverberi part numbers for every serviceable component.

4,000 PSI in the 3.5 GPM Platform — When Maximum Impact Force Is the Priority

Deep Cleaning. Aggressive Degreasing. Surface Preparation. 4,000 PSI Where It Counts.

• 4,000 PSI impact force on a compact 3.5 GPM platform — the RRV35G40-VRT-PKG delivers 4,000 PSI cleaning force through a 3.5 GPM flow rate — the specification for operators who prioritize impact pressure over volume output. Deep grease removal, surface contamination that resists lower-pressure approaches, and surface preparation for coatings and sealants all benefit from the additional 400 PSI that separates the RRV35G40-VRT-PKG from its 3,600 PSI sibling.
• Bronze connecting rods at 4,000 PSI — above the 3,600 PSI threshold where bronze is the required connecting rod specification, the RRV35G40-VRT-PKG’s bronze rods deliver the strength and fatigue tolerance needed for sustained 4,000 PSI commercial operation across the full range of contractor, fleet, agricultural, and industrial cleaning programs
• VRT plumbed Easy Start is critical at 4,000 PSI — a gasoline engine starting against 4,000 PSI of hydraulic back pressure works substantially harder than one starting under zero load. The RRV35G40-VRT-PKG’s Easy Start feature eliminates that hydraulic resistance on every startup, protecting both the engine and the pump’s bronze rods and packing across thousands of daily start cycles
• Auto-reset TRV protects precision components at 4,000 PSI — at maximum rated pressure, bypass water heats faster and ceramic plungers, dual redundant packing, and manifold seals are operating at their rated design limits. The auto-reset TRV monitors temperature continuously, vents heat when it builds, and draws ambient supply water to restore safe operating conditions — automatically, without interrupting the cleaning program

Typical Applications

Where the RRV35G40-VRT-PKG Delivers Best Results

• Contractor surface prep, graffiti removal, and equipment washdowns — the RRV35G40-VRT-PKG’s 4,000 PSI output and complete VRT plumbed package deliver maximum impact force for surface preparation, coating removal, and equipment cleaning where 3,600 PSI output approaches its limits on heavy contamination
• Fleet maintenance — buses, trucks, trailers, and service vehicles — the Easy Start and auto-reset TRV support high-cycle daily fleet washing programs where the engine starts and stops frequently and sustained 4,000 PSI performance is required across full working days
• Agricultural barns, pens, tractors, and farm equipment sanitation — 4,000 PSI at 3.5 GPM handles demanding agricultural cleaning programs with the VRT plumbed package’s thermal protection supporting extended seasonal duty cycles
• Industrial and food processing plant washdowns — production washdowns, floor sanitation, and conveyor-area cleaning where the RRV35G40-VRT-PKG’s bronze rod construction and factory-calibrated 4,000 PSI pressure management meet sustained industrial cleaning demands
• Municipal sidewalks, parking facilities, and public works — gas engine-powered municipal cleaning systems where standardized VRT plumbed packages with national parts availability support scheduled cleaning programs at maximum impact pressure
