RKV35G30ADF24C2 | 3.5 GPM 3000 PSI Triplex Pump Unloader Installed

RKV35G30ADF24C2 by Annovi Reverberi — RK Series Triplex Plunger Pump with Gymatic Unloader | 3.5 GPM | 3,000 PSI | Internal Recirculation | Banjo Bolt Connections | 1″ Hollow Keyway Shaft | SAE J609A Gas and Diesel Engine Drive | No Chemical Injector

The RKV35G30ADF24C2 by Annovi Reverberi is a commercial-grade RK Series triplex ceramic plunger pump engineered for direct gas and diesel engine-driven pressure washing systems requiring 3.5 GPM at 3,000 PSI with Gymatic bypass pressure regulation and straight high-pressure water delivery. Rated at 3.5 GPM and 3,000 PSI, the RKV35G30ADF24C2 delivers 10,500 cleaning units — balancing 3.5 GPM coverage speed with 3,000 PSI impact for efficient cleaning of concrete, siding, vehicles, machinery, and large outdoor surfaces — through a reinforced pump housing with precision-machined internal passages, an F24 SAE J609A direct-drive flange for compact belt-free coupling to gasoline or diesel engines, and a factory-installed adjustable bypass unloader with internal recirculation and banjo bolt connections.

The RKV35G30ADF24C2 is particularly well suited for operators who need dependable performance without stepping up to heavier high-PSI industrial platforms — an excellent balance of power, efficiency, and long service life for contractors, fleet operators, and facility maintenance teams who depend on consistent results daily. Built by Annovi Reverberi in Modena, Italy — with US-based operations, a domestic parts distribution network, and dedicated AR North America technical support — this pump arrives pre-filled with AR break-in oil, factory-tested, and ready for immediate installation. Protected by a 5-year US limited warranty through AR North America and built to be fully rebuilt rather than replaced, the RKV35G30ADF24C2 is a long-term investment capable of a decade of productive service life.

Factory-Matched and Approved — The RKV35G30ADF24C2 Complete Assembly Advantage

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

Every RKV35G30ADF24C2 ships as a factory-matched, factory-approved, and factory-installed complete pump and unloader assembly:

• Factory-matched C2 for 3,000 PSI — the Gymatic adjustable bypass unloader with internal recirculation is factory-calibrated for this pump’s 3.5 GPM / 3,000 PSI operating point, ensuring predictable pressure behavior and stable bypass response from first startup.
• Factory-approved configuration — the complete assembly is AR North America’s validated specification for this model. Operating with the factory-installed components maintains full 5-year warranty coverage.
• Factory-installed and tested — every RKV35G30ADF24C2 exits the AR manufacturing facility with the unloader 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, connect system hoses using the supplied banjo bolts and O-rings, add fuel, and start. Ready from day one.

Decoding the RKV35G30ADF24C2 Model Number

What Every Segment of This AR Pump Designation Tells You

• RKV — Pump series: RK Series triplex plunger pump — AR’s commercial industrial pump platform
• 30 — Maximum pressure: 3,000 PSI — 3.5 × 3,000 = 10,500 cleaning units
• D — Shaft version: Direct Gas/Diesel Drive — 1″ hollow keyway crankshaft bore for direct coupling to engine output shafts per AR North America model designation convention
• F24 — Flange type: SAE J609A direct-drive flange — close coupling to gas or diesel engines with a 1″ I.D. cylindrical shaft (AR part AR41866)
• C2 — Unloader code: Gymatic — adjustable bypass unloader with internal recirculation; AR’s factory-approved specification for this model
• No trailing I suffix — model terminates at C2, confirming straight 3,000 PSI water output without a factory-installed downstream chemical injector

Gymatic C2 Unloader — Internal Recirculation with Banjo Bolt Connections

Factory-Approved. Adjustable. Thermally Managed Bypass. Flexible Plumbing.

• Internal bypass recirculation — manages pressure spikes when the trigger gun is released on the RKV35G30ADF24C2, preventing damage from dead-heading and overheating while reducing heat buildup during idle cycles
• Smooth pressure transitions — internal recirculation reduces hose whip and system shock at trigger release, improving operator comfort and extending the service life of hoses, fittings, and downstream accessories
• Adjustable pressure regulation — precisely match system pressure to specific cleaning tasks on the RKV35G30ADF24C2. Compatible with surface cleaners, turbo nozzles, foam cannons, and downstream chemical injectors when properly sized.
• Banjo bolt connections with sealing O-rings — allow flexible plumbing configurations, simplify installation, and ensure secure leak-resistant connections without additional adapters. Especially useful for OEM builds and service replacements on the RKV35G30ADF24C2.
• No factory-installed injector — straight 3,000 PSI water output. Chemical delivery managed externally through a dedicated downstream injector or soft wash system when soap application is required.
• Compact integrated design — factory-installed unloader reduces setup time and eliminates guesswork, making the RKV35G30ADF24C2 well suited for professional installers and end users who value simplicity and uptime
