The RRV4G40-PKG by Annovi Reverberi is a complete, installation-ready 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. Rated at 4.0 GPM and 4,000 PSI, the RRV4G40-PKG delivers 16,000 cleaning units — the output of a serious professional cleaning platform built for contractor rigs, fleet wash bays, agricultural operations, industrial facilities, and OEM skid systems — through bronze connecting rods, solid ceramic plungers, a forged brass manifold, stainless steel valves, dual redundant packing, and an F24 SAE J609a direct-drive flange with 1″ shaft. This package goes further than most: a garden hose hook-up adapter and stainless steel 80 mesh filter screen ship in the box, so connecting a water supply is as simple as screwing on a garden hose. As part of Annovi Reverberi’s pump and unloader assemblies stocked and supported by WSHPWR, the RRV4G40-PKG is the most complete pump package answer for operators who need 4,000 PSI ready to run from the first connection.

The RRV4G40-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. Mount it to a compatible engine. Thread on the garden hose. Connect the high-pressure hose. Add fuel. Start the engine. The RRV4G40-PKG is washing. Protected by a 5-year US limited warranty and built to be fully rebuilt rather than replaced, this is a decade-of-service investment.

Everything in One Box — The RRV4G40-PKG Complete Package Contents

Garden Hose In. High-Pressure Hose Out. Bolt On and Wash.

Open the RRV4G40-PKG box and find everything required for a complete, same-day engine-to-pump installation — including the inlet hardware that most packages leave out:

• RRV4G40 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. Ready to mount.
• Gymatic C2 adjustable unloader with tamper-resistant and lockable bypass regulation — factory-matched and factory-installed for the 4.0 GPM / 4,000 PSI duty point. Smooth pressure regulation, safe bypass, and lockable pressure setting for fleet wash bays and multi-operator systems where consistent, tamper-proof pressure settings matter. Banjo bolts and sealing O-rings included.
• Garden hose hook-up adapter — connects directly to a standard garden hose. Thread it on and your water supply is connected. No additional inlet fittings required.
• Stainless steel 80 mesh filter screen — factory-included inline filter protects ceramic plungers, valves, and packing from particulate contamination in the supply water. Easy to clean and replace. This is the component that many operators forget to source separately — it ships in the box.
• Mounting hardware with lockable washers — secure, vibration-resistant mounting on contractor skids, trailer frames, flatbed rigs, and OEM installations. Lockable washers maintain fastener tension under the sustained vibration of continuous gas engine operation.
• Chemical injector and suction hose — not included — the RRV4G40-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 and connected to the system outlet. Choose the draw rate and connection style that matches your cleaning program.
• Factory break-in oil — crankcase pre-filled. First-startup protection already handled.
• Vented dipstick — crankcase ventilation and oil level verification from day one.
• Thermal relief valve with auto-reset — protects the pump head from overheating during extended bypass periods and automatically resets when temperature returns to safe operating range. No manual reset required between cleaning cycles.
• Operating instruction manual — complete setup, operating, service, and rebuild procedures with Annovi Reverberi part numbers for every component. AR North America parts availability confirmed across North America.

The Garden Hose Adapter and 80 Mesh Filter — Why They Matter

Garden Hose In. Protected Pump. Immediate Operation. No Extra Trip to the Parts Counter.

Most pump packages stop at the pump and unloader. The RRV4G40-PKG goes further — and the two components that make the difference are the ones most often forgotten:

• Garden hose adapter — the missing link — without an inlet adapter, the pump sits on the frame and waits while the operator sources fittings. The RRV4G40-PKG includes the garden hose adapter so the water supply connection is solved before the box is opened. Thread it on. Turn on the water. The pump is ready to prime.
• Stainless steel 80 mesh filter screen — the protection nobody talks about — ceramic plungers, stainless valves, and dual redundant packing are precision components. Supply water contaminated with sand, sediment, pipe scale, or debris accelerates wear on all three. The included 80 mesh filter screen intercepts particulate before it reaches the pump. It is easy to clean, easy to replace, and already in the box. An 80 mesh screen is a standard recommendation for any triplex pump installation — in the RRV4G40-PKG it is standard equipment.
• Auto-resetting thermal relief — when the pump is left in bypass with the engine running, heat builds in the pump head. The auto-resetting thermal relief valve vents the excess heat and resets automatically when temperature normalizes — no manual intervention between cleaning cycles, no damage to ceramic plungers or packing from thermal spikes.
• Tamper-resistant lockable bypass — fleet wash bays and multi-operator contractor rigs benefit from lockable pressure settings. The RRV4G40-PKG’s tamper-resistant bypass regulation keeps the pump operating at the correct pressure setting regardless of who is running the equipment.

Built for the Predator-Powered Contractor Rig

Flatbed. Multi-Unit. Garden Hose Ready. Maximum Output Per Dollar.

• Build your own system — own the savings and the quality — a Predator 420cc / 13 HP paired with the RRV4G40-PKG delivers 16,000 cleaning units of sustained commercial output at a fraction of OEM-assembled pressure washer costs. The RRV4G40-PKG’s included garden hose adapter, 80 mesh filter, and lockable mounting hardware mean the system is operational the moment installation is complete — no additional sourcing, no delay.
• Standardize your flatbed for maximum uptime — contractors running multiple identical Predator/RRV4G40-PKG stations gain standardized parts, standardized service procedures, and standardized performance across every unit on the rig. The tamper-resistant lockable bypass ensures every station operates at the same calibrated pressure regardless of who services it.
• AR North America national parts network — every wear component in the RRV4G40-PKG is stocked through AR North America’s domestic distribution. Rebuild kits, packing kits, valve assemblies, unloader service parts, replacement filter screens — available nationally. The rig keeps running.
