RRV4G40-VRT-PKG-A by Annovi Reverberi — Complete VRT Plumbed RRV Series Triplex Pump Package with Anodized Crankcase | 4.0 GPM | 4,000 PSI | Bronze Connecting Rods | Forged Brass Manifold | F24 SAE J609a 1″ Shaft | VRT Unloader with Easy Start | Auto-Reset Thermal Relief | 16,000 Cleaning Units

The RRV4G40-VRT-PKG-A by Annovi Reverberi is a complete, factory-assembled VRT plumbed RRV Series triplex ceramic plunger pump package engineered for direct drive gas engine-powered pressure washing systems requiring 4.0 GPM at 4,000 PSI with an anodized crankcase for enhanced surface hardness and corrosion resistance in chemically aggressive, high-humidity, and demanding industrial environments. Rated at 4.0 GPM and 4,000 PSI, the RRV4G40-VRT-PKG-A delivers 16,000 cleaning units — the output of a heavy-duty professional cleaning platform built for contractors, fleet operators, OEM builders, agricultural operations, and industrial facilities — through bronze connecting rods, solid ceramic plungers, a forged brass manifold, stainless steel valves, dual redundant packing, an anodized aluminum crankcase, and an F24 SAE J609a 1″ hollow shaft for direct coupling to compatible gasoline engines. As part of Annovi Reverberi’s pump and unloader assemblies stocked and supported by WSHPWR, the RRV4G40-VRT-PKG-A is the correct specification when 4,000 PSI performance needs to be paired with the elevated crankcase protection that standard aluminum cannot deliver.

The RRV4G40-VRT-PKG-A 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 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 RRV4G40-VRT-PKG-A is a decade-of-service investment in the most durable crankcase specification in the RRV 4,000 PSI lineup.

Everything in One Box — The RRV4G40-VRT-PKG-A Complete VRT Plumbed Package

Factory-Plumbed. Factory-Tested. Anodized Crankcase. Nothing Left to Source.

Open the RRV4G40-VRT-PKG-A box and find a complete, factory-plumbed, gas engine-ready installation with anodized crankcase protection:

• RRV4G40 triplex ceramic plunger pump with anodized crankcase — factory-tested and pre-lubricated with break-in oil. Anodized aluminum crankcase, 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 gas engine coupling. Ready to mount.
• VRT external bypass unloader — factory-plumbed and pressure-set — the VRT unloader is factory-calibrated for the 4.0 GPM / 4,000 PSI duty point and plumbed into the complete bypass circuit before shipment. Smooth pressure regulation, stable bypass behavior, and controlled 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. Once the engine reaches operating speed, the bypass closes and the system builds to 4,000 PSI. Easier starts on every pull. Less starter wear. 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.
• Fittings and mounting hardware — 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 RRV4G40-VRT-PKG-A 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.
• Operator’s manual and service schematics — complete installation, startup, operating, and maintenance procedures with Annovi Reverberi part numbers for every serviceable component.

A — The Anodized Crankcase Upgrade

Electrochemical Surface Hardening. Harder. More Corrosion Resistant. Built for Aggressive Environments.

The A designation on the RRV4G40-VRT-PKG-A identifies a crankcase specification that adds meaningful protection in environments where standard aluminum crankcases experience accelerated surface wear or corrosion — and understanding what anodizing actually does is the key to knowing whether this is the correct specification for your application:

• What anodizing is — anodizing is an electrochemical process that converts the surface layer of aluminum into aluminum oxide — a ceramic-like compound that is significantly harder than the base aluminum beneath it. The anodized layer is not a coating applied on top of the surface; it is a transformation of the surface itself. It cannot peel, flake, or chip under normal operating conditions. On the RRV4G40-VRT-PKG-A, the anodized crankcase housing carries this hardened surface treatment across all exposed aluminum crankcase surfaces.
• Enhanced corrosion resistance — aluminum oxide is substantially more resistant to chemical attack than bare aluminum. In environments where the crankcase exterior is exposed to cleaning chemistry overspray, fertilizer residue, salt air, industrial vapors, or aggressive sanitation agents, the anodized surface of the RRV4G40-VRT-PKG-A resists the pitting and surface degradation that affects standard aluminum crankcases over extended service in the same conditions.
• Increased surface hardness — the aluminum oxide layer created by anodizing is significantly harder than the base aluminum. In belt drive and direct drive installations where abrasive debris, grit, or particulate contamination contacts crankcase surfaces during operation, the anodized surface resists surface wear that would scratch or abrade standard aluminum over time.
• When to specify the A anodized crankcase over the standard RRV4G40-VRT-PKG — agricultural environments with fertilizer and chemical residue overspray; coastal and marine-adjacent installations with salt air exposure; food processing facilities with caustic sanitation chemistry in the operating environment; industrial environments with airborne chemical or abrasive particulate; and any installation where the crankcase exterior will experience sustained exposure to corrosive agents in the surrounding environment. If the operating environment is clean water and standard wash-down conditions, the standard RRV4G40-VRT-PKG is the correct specification. If the environment involves the conditions above — the A anodized crankcase is the investment that protects the housing across a decade of service.

Typical Applications

Where the RRV4G40-VRT-PKG-A Is the Correct Specification

• Agricultural environments with fertilizer residue, pesticide overspray, and chemical exposure — the RRV4G40-VRT-PKG-A’s anodized crankcase resists the corrosive surface attack that agricultural chemical environments accelerate on standard aluminum crankcases across seasonal service cycles
• Coastal and marine-adjacent installations with salt air exposure — salt air accelerates aluminum surface corrosion on standard crankcases. The anodized surface of the RRV4G40-VRT-PKG-A maintains crankcase integrity in coastal contractor rigs, marine facility wash systems, and elevated-humidity coastal environments
• Food and beverage processing facilities — USDA-compliant washdown programs where caustic sanitation chemistry and high-humidity environments create conditions that benefit from anodized crankcase protection at 4,000 PSI operating pressure
• Industrial plants with airborne chemical or abrasive particulate — manufacturing environments where airborne contamination contacts the pump crankcase during operation; the anodized surface resists both chemical attack and abrasive wear from particulate in the operating environment
• Contractor mobile rigs, fleet washing, and municipal operations — gas engine-driven professional cleaning systems where the anodized crankcase provides the additional protection margin that justifies the specification upgrade over the standard RRV4G40-VRT-PKG in demanding operating environments
