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 RRV35G36-VRT-PKG is a decade-of-service investment in the mid-range RRV VRT plumbed specification.

Everything in One Box — The RRV35G36-VRT-PKG Complete VRT Plumbed Package

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

Open the RRV35G36-VRT-PKG box and find a complete, factory-plumbed, gas engine-ready installation:

• RRV35G36 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 9–15 HP 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 / 3,600 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 with minimal effort. Once the engine reaches operating speed, the bypass closes and the system builds to 3,600 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 standardized bolt pattern — 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 RRV35G36-VRT-PKG delivers straight 3,600 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. AR North America parts availability confirmed nationally.

The VRT Plumbed Package Advantage at 3,600 PSI Balanced Output

Easy Start. Auto-Reset TRV. Factory-Plumbed Bypass. The Complete Mid-Range Specification.

• Easy Start on a 3,600 PSI pump protects the engine at every startup — a 9–15 HP gasoline engine starting against 3,600 PSI of hydraulic back pressure works significantly harder than one starting under zero load. The RRV35G36-VRT-PKG’s Easy Start feature eliminates that hydraulic resistance on every startup — across thousands of daily starts over the pump’s service life, this directly reduces recoil starter wear and keeps the engine starting cleanly through years of contractor and fleet washing duty cycles.
• Auto-reset TRV protects the pump in mid-range duty cycle applications — contractor rigs and fleet wash systems using the RRV35G36-VRT-PKG frequently run extended trigger-off intervals during positioning, repositioning, and operator break periods. During these intervals, bypass water temperature rises. The automatic TRV monitors continuously, vents heat as it builds, and draws ambient supply water to restore safe operating temperature — protecting bronze rods, dual redundant packing, and manifold seals without operator intervention.
• Factory-plumbed bypass loop standardizes installation — the complete bypass circuit arrives connected and verified. Contractors and OEM builders skip the bypass assembly step entirely — saving installation time and eliminating the risk of incorrectly plumbed bypass circuits that cause premature pump wear.

Typical Applications

Where the RRV35G36-VRT-PKG Delivers Best Results
