RRV35G36D-VRT3 Pressure Washer Pump | 3.5 GPM 3800 PSI

RRV35G36D-VRT3 by Annovi Reverberi — RRV Series Commercial Triplex Plunger Pump with VRT3 External Adjustable Unloader | 3.5 GPM | 3,800 PSI | Forged Brass Head | Bronze Connecting Rods | 1″ Key Shaft | Direct Drive Gas Engine

The RRV35G36D-VRT3 by Annovi Reverberi is a commercial-grade RRV Series triplex plunger pump engineered for direct drive gas engine-driven pressure washing systems requiring 3.5 GPM at 3,800 PSI with operator-adjustable pressure output via an external VRT3 unloader system. Rated at 3.5 GPM and 3,800 PSI, the RRV35G36D-VRT3 delivers 13,300 cleaning units — combining 3.5 GPM output with 3,800 PSI cleaning force for fleet washing, industrial cleaning, contractor building washdowns, agricultural equipment, and OEM skid and trailer systems requiring field-adjustable pressure control — through a forged brass head, solid ceramic plungers, stainless steel valves with premium high-pressure seals, bronze connecting rods, and a standard 1″ keyway shaft for broad gas engine compatibility. As part of Annovi Reverberi’s pump and unloader assemblies stocked and supported by WSHPWR, the RRV35G36D-VRT3 arrives factory-tested and ready to install.

The RRV35G36D-VRT3 carries the external VRT3 adjustable unloader — providing manual pressure control from lower settings for delicate surfaces up to maximum 3,800 PSI output for heavy contamination, with the unloader positioned externally for accessible in-field pressure adjustment without tools. Built by Annovi Reverberi in Modena, Italy — with US-based operations, a domestic parts distribution network, and dedicated technical support — this pump arrives pre-filled with factory break-in oil, factory-tested, and ready for installation. Protected by a 5-year US limited warranty and built to be fully rebuilt rather than replaced, the RRV35G36D-VRT3 is a long-term investment capable of a decade of productive service life.

Factory-Matched and Approved — The RRV35G36D-VRT3 Complete Assembly Advantage

No Mismatches. No Guesswork. No Warranty Risk. Just Install and Run.

Every RRV35G36D-VRT3 ships as a factory-matched, factory-approved, and factory-installed complete pump and unloader assembly:

• Factory-matched VRT3 for 3,800 PSI — the external VRT3 adjustable unloader is factory-calibrated for this pump’s 3.5 GPM / 3,800 PSI duty point, providing predictable pressure behavior and stable bypass response from first startup.
• Factory-approved configuration — the complete assembly is Annovi Reverberi’s validated specification for this model. Operating with the factory-installed components maintains full 5-year warranty coverage.
• Factory-installed and tested — every RRV35G36D-VRT3 exits the manufacturing facility with the VRT3 assembly mounted, calibrated, and tested for flow, pressure, and leak-free operation before shipment.
• Eliminates mismatch returns — the factory-matched assembly eliminates incorrect unloader specification — the most common source of pump system returns — before the pump leaves the box.
• Stress-free installation — mount to the engine via the 1″ keyway shaft, connect system hoses, and start. The RRV35G36D-VRT3 arrives engineered, assembled, and ready.

VRT3 External Adjustable Unloader — Field-Adjustable Pressure Control at 3,800 PSI

External Knob. Manual Adjustment. Commercial-Grade Pressure Regulation.

• External placement for accessible in-field adjustment — the VRT3 unloader on the RRV35G36D-VRT3 is positioned externally with a manual adjustment knob, allowing operators to fine-tune pressure output from lower settings for delicate surfaces to maximum 3,800 PSI for heavy contamination without tools or disassembly
• Start low, increase gradually — per Annovi Reverberi installation guidance for the RRV35G36D-VRT3: set the VRT3 unloader to a lower pressure setting and increase gradually to the desired working pressure after confirming system and accessory ratings
• Bypass protection at trigger release — the VRT3 unloader diverts flow when the trigger gun is released on the RRV35G36D-VRT3, protecting the pump and engine from pressure spikes during stop-start commercial cleaning cycles
• Customizable for varied surfaces and job requirements — fleet washing, building washdown, concrete cleaning, surface preparation, and agricultural equipment all require different pressure settings. The VRT3’s field-adjustable output makes the RRV35G36D-VRT3 adaptable across varied commercial accounts without unloader replacement
• Straight 3,800 PSI water output — no factory-installed injector on the RRV35G36D-VRT3. Chemical delivery managed externally when detergent application is required.

Forged Brass Head and Bronze Connecting Rods — Commercial-Duty Construction at 3,800 PSI

Forged Brass. Bronze Rods. Ceramic Plungers. Stainless Valves. Built for Commercial Volume.

• Forged brass head — the RRV35G36D-VRT3’s forged brass manifold head delivers higher structural integrity and corrosion resistance than standard cast alternatives, engineered for sustained 3,800 PSI operation in demanding commercial environments with varied water quality
• Bronze connecting rods above 3,600 PSI — bronze connecting rods are standard specification above 3,600 PSI. The RRV35G36D-VRT3’s bronze rods provide the strength and wear resistance required for sustained commercial-duty high-pressure operation across fleet washing, industrial cleaning, and contractor applications
• Ceramic plungers for cooler operation — solid ceramic plungers on the RRV35G36D-VRT3 reduce friction and heat buildup, extending seal life during the extended continuous-duty operation typical of commercial cleaning accounts
• Stainless steel valves with premium high-pressure seals — engineered for long-term sealing integrity under the repeated high-pressure cycles of commercial fleet washing, contractor work, and industrial cleaning on the RRV35G36D-VRT3

Typical Applications

Where the RRV35G36D-VRT3 Delivers Best Results
