RRV4G40HDF24-PKG | 4.0 GPM 4000 PSI Triplex Pump Package

RRV4G40HDF24-PKG by Annovi Reverberi — Complete RRV Series Triplex Pump Package with Nickel Plated Brass Head | 4.0 GPM | 4,000 PSI | Bronze Connecting Rods | Gymatic C2 Unloader | F24 SAE J609a 1″ Shaft | Direct Drive Gas Engine | 16,000 Cleaning Units

The RRV4G40HDF24-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 with a Nickel Plated Brass Head for maximum corrosion resistance in demanding chemical environments. Rated at 4.0 GPM and 4,000 PSI, the RRV4G40HDF24-PKG delivers 16,000 cleaning units — the output of a heavy-duty professional cleaning platform built for contractors, fleet wash bays, industrial degreasing stations, agricultural sanitation operations, food and beverage processing facilities, and OEM system builders who need 4,000 PSI with the enhanced chemical resistance only a nickel plated manifold delivers — through bronze connecting rods, solid ceramic plungers, a Nickel Plated Brass Head manifold, stainless steel valves, dual redundant packing, and an F24 SAE J609a direct-drive flange with 1″ shaft. Every fitting, every bolt, the unloader, and the manual ship in one organized box. Mount it. Connect it. Wash. As part of Annovi Reverberi’s pump and unloader assemblies stocked and supported by WSHPWR, the RRV4G40HDF24-PKG is the complete answer for operators who need 4,000 PSI and the chemical durability to back it up.

The RRV4G40HDF24-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. The H designation confirms the Nickel Plated Brass Head — the single specification that separates this package from the standard RRV4G40-PKG for operators who run aggressive detergents, sanitizers, degreasers, or process chemicals through their pressure washing systems daily. 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 RRV4G40HDF24-PKG Complete Package Contents

No Return Trips. No Guesswork. No Compatibility Risk. Same-Day Install.

Open the RRV4G40HDF24-PKG box and find everything required for a complete engine-to-pump installation:

• RRV4G40H triplex ceramic plunger pump with Nickel Plated Brass Head — factory-tested and pre-lubricated with break-in oil. Nickel plated manifold, bronze connecting rods, solid ceramic plungers, stainless steel valves, dual redundant packing, oversized crankshaft bearings — factory-installed and factory-verified. Ready to mount.
• Gymatic C2 adjustable unloader with banjo bolts and sealing O-rings — factory-matched and factory-installed for the 4.0 GPM / 4,000 PSI duty point. Smooth pressure regulation and safe bypass from first startup. The right unloader for this pump. Already on it.
• Fittings and mounting hardware — every fitting and fastener required for integration onto contractor skids, fleet wash frames, flatbed rigs, and OEM installations. Organized in the box. Nothing to source separately.
• Chemical injector and suction hose — not included — the RRV4G40HDF24-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.
• Oil sight glass and vented dipstick — at-a-glance oil monitoring from day one.

The H Designation — Nickel Plated Brass Head at 4,000 PSI

Enhanced Corrosion Resistance. Chemical-Duty Ready. The Upgrade That Matters.

The H designation on the RRV4G40HDF24-PKG identifies the single most significant specification upgrade from the standard RRV4G40-PKG — and for operators who run aggressive chemicals through their pressure washing systems, it is the specification that protects the investment:

• Nickel plating over forged brass — the RRV4G40HDF24-PKG’s manifold head combines the structural strength and pressure fatigue resistance of forged brass with a nickel plating layer that creates a harder, more chemically inert surface. Nickel resists attack from acids, alkalines, degreasers, sanitizers, and process chemicals that can pit and corrode unprotected brass manifolds over time in high-frequency chemical washing applications.
• Critical for chemical-intensive environments — food and beverage facilities running caustic sanitation chemistry, agricultural operations using fertilizer residue washdown, industrial plants running aggressive degreasers, and contractors applying pre-treatment chemicals regularly all benefit from the RRV4G40HDF24-PKG’s nickel plated surface where unprotected brass manifolds experience accelerated corrosion under the same conditions.
• Same 4,000 PSI rated output — elevated chemical durability — the RRV4G40HDF24-PKG delivers identical 4.0 GPM / 4,000 PSI / 16,000 cleaning unit performance as the standard RRV4G40-PKG. The nickel plated head adds chemical corrosion resistance without changing the pressure rating, flow characteristics, or operating speed of the package.
• The right specification for high-chemical duty — if your cleaning program involves daily detergent application, agricultural chemical residue contact, food-grade sanitizers, or industrial degreasers, the RRV4G40HDF24-PKG’s Nickel Plated Brass Head is the correct long-term specification. Standard brass is adequate for clean water and light detergent use. Nickel plated brass is built for chemical duty.

Engine Compatibility — What Drives the RRV4G40HDF24-PKG

F24 SAE J609a. 1″ Hollow Keyway Shaft. Predator-Compatible. Broad Engine Range.

The RRV4G40HDF24-PKG‘s F24 SAE J609a direct-drive flange accepts a 1″ hollow keyway shaft. At 4,000 PSI and 4.0 GPM, engine horsepower is critical. Confirmed compatible platforms include:

• Harbor Freight Predator 420cc / 13 HP — compatible with the RRV4G40HDF24-PKG F24 1″ keyway shaft. Confirm engine HP is appropriate for sustained 4,000 PSI duty cycles. Direct value-priced replacement for Honda GX390, Briggs & Stratton XR2100, and Kohler CH440 — the primary contractor choice for Predator-powered chemical-duty rigs built around the RRV4G40HDF24-PKG.
• Harbor Freight Predator 459cc / 15.8 HP Max Performance — up to 10% more torque than the standard 420cc. Direct replacement for Honda GX390, Briggs & Stratton XR2100, and Kohler CH440. Compatible with the RRV4G40HDF24-PKG F24 1″ keyway shaft — the preferred single-cylinder Predator pairing for sustained high-pressure continuous-duty operation.
• Harbor Freight Predator 670cc / 22 HP V-Twin — the preferred pairing for sustained 4,000 PSI continuous-duty chemical cleaning operations. Delivers the engine overhead needed to keep the RRV4G40HDF24-PKG running at rated pressure across full-day programs involving repeated chemical application cycles. Replaces Honda GX630/660/690 and Briggs & Stratton Vanguard at significant cost savings.
• Honda GX390 — 389cc, 1″ SAE J609a keyway shaft. Direct-mount compatible with the RRV4G40HDF24-PKG F24 flange.

Typical Applications

Where the RRV4G40HDF24-PKG Delivers Best Results

• Food and beverage processing facilities — conveyor and floor sanitation using approved caustic and acid-based sanitation chemistry where the RRV4G40HDF24-PKG’s Nickel Plated Brass Head resists chemical attack that unprotected brass manifolds cannot match in daily chemical wash cycles
• Agricultural sanitation operations — barn sanitation, livestock facility washdown, and equipment cleaning involving agricultural chemical residues where chemical contact with the pump manifold is unavoidable and nickel plating provides the durability margin that protects the investment
• Industrial degreasing and plant sanitation — machinery wash stations, process-area cleaning, and maintenance bays running aggressive solvent-based or alkaline degreasers where the RRV4G40HDF24-PKG’s chemical-resistant head construction extends service life under demanding industrial chemical contact
• Contractor mobile rigs — surface prep and chemical pre-treatment programs — contractors running pre-treatment chemistry, graffiti removal chemicals, or specialized cleaning agents regularly benefit from the RRV4G40HDF24-PKG’s nickel plated protection over the long service life of a 4,000 PSI commercial pump
• Fleet wash operations — trucks, buses, and heavy trailers where fleet wash chemistry and detergent programs involve regular chemical contact with the pump system
• Municipal services — sidewalks, transit vehicles, and public works facilities where sanitation chemistry or cleaning agents are part of the standard cleaning program
