The RRV3G36-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 3.0 GPM at 3,600 PSI in a compact, professional footprint. Rated at 3.0 GPM and 3,600 PSI, the RRV3G36-PKG delivers 10,800 cleaning units — combining 3,600 PSI professional cleaning pressure with a compact 3.0 GPM flow rate for contractor surface prep rigs, fleet cleaning systems, agricultural wash stations, and OEM builds where 3,600 PSI capability is required without the larger footprint of a 4.0 GPM package — 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 for direct coupling to compatible 11–13 HP gasoline engines. 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 RRV3G36-PKG is the complete compact 3,600 PSI answer for operators who need professional pressure without a large-frame engine.

The RRV3G36-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. Whether you are replacing a worn pump on a compact contractor rig, building a portable skid for surface preparation, specifying a pump for an OEM installation requiring 3,600 PSI in a reduced footprint, or outfitting a Predator-powered flatbed with compact high-pressure stations — the RRV3G36-PKG eliminates every compatibility question before the box is opened. Protected by a 5-year US limited warranty and built to be fully rebuilt rather than replaced, this is a decade-of-service investment.

Decoding the RRV3G36-PKG

What This Annovi Reverberi Pump Package Designation Tells You

• RRV — Pump series: RRV Series commercial triplex plunger pump — Annovi Reverberi’s heavy-duty gas engine commercial platform
• 3G — Pump series identifier for this compact RRV configuration
• 36 — Maximum pressure: 3,600 PSI — 3.0 × 3,600 = 10,800 cleaning units
• PKG — Complete package: pump, Gymatic C2 unloader with banjo bolts, fittings, mounting hardware, thermal relief valve, manual, and factory break-in oil — everything required for a complete engine-to-pump installation in one organized box

RRV 3,600 PSI Family — 3.0 GPM vs 4.0 GPM

Both models share the RRV Series platform, 3,600 PSI pressure rating, bronze connecting rods, forged brass manifold, Gymatic C2 unloader, and F24 SAE J609a 1″ shaft. Flow rate and footprint are the key differences:

• RRV3G36-PKG (this model) — 3.0 GPM / 10,800 CU. Compact footprint for portable rigs, smaller OEM builds, and installations where engine size and frame weight are design constraints. Full 3,600 PSI capability in a lighter, more mobile package.
• RRV4G36-PKG — 4.0 GPM / 14,400 CU. Higher flow for fleet wash bays, industrial degreasing, and applications where coverage speed and volume output drive productivity on larger engine platforms.

Engine Compatibility — What Drives the RRV3G36-PKG

F24 SAE J609a. 1″ Hollow Keyway Shaft. 11–13 HP Range. Predator-Compatible.

The RRV3G36-PKG‘s F24 SAE J609a direct-drive flange accepts a 1″ hollow keyway shaft rated for 11–13 HP gasoline engines. The 3.0 GPM / 3,600 PSI output is engineered for this engine range — high pressure without requiring the larger 13–16 HP platforms that the 4.0 GPM packages demand:

• Harbor Freight Predator 420cc / 13 HP — the top of the RRV3G36-PKG’s compatible range and the primary contractor pairing for portable high-pressure builds. Direct value-priced replacement for Honda GX390, Briggs & Stratton XR2100, and Kohler CH440. Compatible with the F24 1″ keyway shaft — delivers 3,600 PSI at 3.0 GPM efficiently without overworking the engine at this output level.
• 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 RRV3G36-PKG F24 1″ keyway shaft — the preferred single-cylinder Predator pairing for sustained high-pressure continuous-duty operation.

3,600 PSI in a Compact 3.0 GPM Package — When Size and Weight Matter

Full Pressure. Smaller Footprint. Lighter Build. Right-Sized for Portable Rigs.

• 3,600 PSI without the 4.0 GPM footprint — the RRV3G36-PKG delivers the same 3,600 PSI professional cleaning pressure as the RRV4G36-PKG in a compact 3.0 GPM package suited to portable contractor rigs, OEM builds with frame weight constraints, and flatbed stations where engine size and pump mounting space are design limits
• Bronze rods at 3,600 PSI — same spec, compact size — the RRV3G36-PKG carries the same bronze connecting rod specification as the larger 4.0 GPM sibling. At 3,600 PSI, bronze rods are the required specification regardless of flow rate. The compact package delivers full commercial durability in a smaller frame.
• Contractor detail and surface prep — at 3.0 GPM and 3,600 PSI, the RRV3G36-PKG is a natural fit for surface preparation, graffiti removal, equipment cleaning, and contractor detail work where 3,600 PSI impact force is required and 4.0 GPM volume output exceeds the application need
• OEM compact system specification — OEM builders designing compact pressure washer systems requiring 3,600 PSI in a reduced footprint can specify the RRV3G36-PKG with confidence that every unit ships factory-tested, factory-assembled, and backed by AR North America’s national parts network

Built for the Predator-Powered Contractor Rig

Compact. Portable. 3,600 PSI Ready. Maximum Output Per Dollar.

• Build your own compact 3,600 PSI system — a Predator 420cc / 13 HP paired with the RRV3G36-PKG delivers 10,800 cleaning units of professional high-pressure output at a fraction of OEM-assembled pressure washer costs. The compact package fits portable contractor rigs, trailer corner stations, and flatbed multi-unit builds where every pound and every inch of mounting space counts.
• Standardize compact stations across a flatbed rig — contractors running multiple compact Predator/RRV3G36-PKG stations on a flatbed gain standardized parts and standardized service across every unit. The RRV Series shares rebuild components with the larger RRV4G36-PKG — one parts order covers both configurations on a mixed-output rig.
• AR North America national parts network — every wear component in the RRV3G36-PKG is stocked through AR North America’s domestic distribution. Rebuild kits, packing kits, valve assemblies, C2 unloader service parts — available nationally. The rig keeps running.
