RKV35G35DF24C2G 3.5 GPM 3500 PSI Triplex Pump | 3400 RPM

RKV35G35DF24C2G by Annovi Reverberi — RK Series Triplex Plunger Pump with Gymatic C2G Unloader | 3.5 GPM | 3,500 PSI | Brass Manifold | Stainless Steel Valves | 1″ Hollow Keyway Shaft | SAE J609A Gas and Diesel Engine Drive | No Chemical Injector

The RKV35G35DF24C2G by Annovi Reverberi is a professional-grade RK Series triplex ceramic plunger pump engineered for direct gas and diesel engine-driven commercial and industrial pressure washing systems requiring 3.5 GPM at 3,500 PSI with Gymatic C2G bypass pressure regulation and straight high-pressure water delivery. Rated at 3.5 GPM and 3,500 PSI at 3,400 RPM, the RKV35G35DF24C2G delivers 12,250 cleaning units — combining 3.5 GPM focused output with 3,500 PSI impact for heavy equipment washdown, concrete cleaning, fleet maintenance, and industrial surface preparation — through a reinforced crankcase with solid ceramic plungers, brass manifold, stainless steel valves, and an F24 SAE J609A direct-drive flange for close-coupling to gasoline or diesel engines.

The RKV35G35DF24C2G carries the C2G unloader designation — confirming the Gymatic assembly in a non-injector arrangement with internal recirculation for bypass thermal management. Straight 3,500 PSI water output for operators managing chemical delivery through an external downstream system. 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 as a complete, factory-tested assembly pre-filled with AR break-in oil, equipped with the factory-matched C2G unloader, and packaged with mounting hardware, operator’s manual, and full parts schematic. Protected by a 5-year US limited warranty through AR North America and built to be fully rebuilt rather than replaced, the RKV35G35DF24C2G is a long-term investment capable of a decade of productive service life.

Factory-Matched and Approved — The RKV35G35DF24C2G Complete Assembly Advantage

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

Every RKV35G35DF24C2G ships as a factory-matched, factory-approved, and factory-installed complete pump and unloader assembly:

• Factory-matched C2G for 3,500 PSI — the C2G Gymatic unloader with internal recirculation is factory-calibrated for this pump’s 3.5 GPM / 3,500 PSI operating point as a complete system, ensuring predictable pressure behavior across the full range of tools and operating conditions.
• 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 RKV35G35DF24C2G exits the AR manufacturing facility with the C2G unloader mounted, calibrated, and tested before shipment. No field calibration from scratch.
• Eliminates mismatch returns — incorrect unloader specification is the most common source of system returns. The factory-matched assembly eliminates this failure mode before the pump leaves the box.
• Stress-free installation — mount to the engine, connect system hoses and inlet supply, add fuel, and start. Ready from day one.

Decoding the RKV35G35DF24C2G 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 with front-access piston packing and valve serviceability
• 35G — Flow rate: 3.5 GPM
• 35 — Maximum pressure: 3,500 PSI — 3.5 × 3,500 = 12,250 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)
• C2G — Unloader code: Gymatic assembly (C2 = Gymatic, G = Gymatic assembly confirmed designation) — non-injector configuration with internal recirculation for bypass thermal management; AR’s factory-approved specification for this model
• No trailing I suffix — model terminates at C2G, confirming straight 3,500 PSI water output without a factory-installed downstream chemical injector

Gymatic C2G Unloader — Internal Recirculation at 3,500 PSI

Factory-Approved. Adjustable. Thermally Managed Bypass. Clean Water Output.

• Internal recirculation for bypass thermal management — the C2G routes bypass water through controlled internal channels when the trigger is released on the RKV35G35DF24C2G, moderating temperature during idle cycles and reducing stress on valves and seals compared to non-recirculating designs
• Simplified plumbing architecture — internal recirculation eliminates external bypass return lines, reducing fitting count, potential leak points, and installation complexity on skid frames and trailer systems
• Adjustable pressure regulation — dial in the ideal PSI for different nozzle sizes, surface types, and cleaning tasks. Supports a wide range of tools from aggressive surface cleaners to detail wands.
• Non-injector configuration — the C2G designation confirms no built-in detergent injection. Chemical delivery managed externally through a dedicated downstream injector or soft wash system when soap application is required.
• System protection — controlled bypass diverts flow safely at trigger release, protecting hoses, guns, and downstream accessories from pressure spikes throughout the operating range
• Compact installation — factory-integrated C2G assembly reduces total plumbing complexity on skid-mounted units, mobile wash trailers, and truck-mounted cleaning systems

Typical Applications

Where the RKV35G35DF24C2G Delivers Best Results

• Commercial pressure washing and contract cleaning — building exteriors, concrete surfaces, vehicle washing, and general commercial cleaning where the RKV35G35DF24C2G’s 12,250 CU output delivers consistent professional results
• Fleet maintenance and vehicle washdown — trucks, trailers, and service vehicles where 3,500 PSI handles road film and grease with chemical applied through a dedicated external system
• Industrial machinery and plant maintenance — production equipment, facility floors, and maintenance areas where reliable continuous-duty output and front-access serviceability minimize downtime
• Agricultural equipment and facility washdown — tractors, implements, and farm facilities on gas or diesel engine-powered rigs where 3.5 GPM output handles large agricultural surface areas
• Municipal services and public works — the RKV35G35DF24C2G’s compact direct-drive design and factory-matched assembly support efficient integration into municipal fleet and facility maintenance programs
• Construction site cleanup and OEM manufacturing — F24 direct-drive mounting, factory-matched C2G unloader, and compact footprint make this pump practical for OEM system builds and contractor rigs
