RKV35G35DF24C2I | 3.5 GPM 3500 PSI Triplex Pump Unloader Installed

RKV35G35DF24C2I by Annovi Reverberi — RK Series Triplex Plunger Pump with Gymatic C2I Unloader and Chemical Injector | 3.5 GPM | 3,500 PSI | Brass Manifold | Stainless Steel Components | 1″ Hollow Keyway Shaft | SAE J609A Gas and Diesel Engine Drive

The RKV35G35DF24C2I by Annovi Reverberi is a heavy-duty 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 integrated downstream chemical application capability. Rated at 3.5 GPM and 3,500 PSI at 3,400 RPM, the RKV35G35DF24C2I delivers 12,250 cleaning units — combining 3.5 GPM focused output with 3,500 PSI impact for high-pressure surface cleaning, degreasing, equipment washdown, and large-area rinsing — through a reinforced crankcase with solid ceramic plungers, brass manifold, stainless steel internal components, and an F24 SAE J609A direct-drive flange for close-coupling to gasoline or diesel engines.

The RKV35G35DF24C2I carries the factory-installed C2I Gymatic adjustable unloader with integrated soap injection — delivering the complete two-mode wash platform from a single factory-configured, factory-approved assembly. Precise pressure regulation, on-demand chemical application, and smooth bypass protection are all built in, simplifying system layout and reducing external plumbing complexity. 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 RKV35G35DF24C2I is a long-term investment capable of a decade of productive service life.

Factory-Matched and Approved — The RKV35G35DF24C2I Complete Assembly Advantage

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

Every RKV35G35DF24C2I ships as a factory-matched, factory-approved, and factory-installed complete pump and unloader assembly:

• Factory-matched C2I for 3,500 PSI — the C2I Gymatic unloader and integrated injector are factory-calibrated for this pump’s 3.5 GPM / 3,500 PSI operating point. Pressure regulation, bypass response, and chemical draw characteristics are factory-set as a complete system.
• 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 RKV35G35DF24C2I exits the AR manufacturing facility with the C2I assembly mounted, calibrated, and tested for flow, pressure, and leak-free operation before shipment.
• Eliminates mismatch returns — the factory-matched assembly eliminates the most common source of system returns — incorrect unloader or injector specification — before the pump leaves the box.
• Stress-free installation — mount to the engine, connect system hoses, connect the detergent supply line to the injector port, add fuel, and start. Ready from day one.

Decoding the RKV35G35DF24C2I 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)
• C2 — Unloader code: Gymatic — AR’s factory-approved unloader specification for this model, with adjustable pressure regulation and integrated bypass
• I — Chemical injector: Included — downstream soap and chemical injector factory-integrated into the Gymatic C2 assembly, enabling low-pressure detergent application without a separate injector fitting

RKV35G35DF24C2I vs RKV35G35DF24C2G — The 3,500 PSI Platform Variants

Both models share the same RK Series platform, F24 flange, 1″ keyway shaft, and 3.5 GPM / 3,500 PSI / 12,250 CU output. The injector is the key difference:

• RKV35G35DF24C2I (this model) — Gymatic C2 with integrated downstream chemical injector. Two-mode wash capability: 3,500 PSI rinse and low-pressure detergent pre-soak.
• RKV35G35DF24C2G — Gymatic C2G non-injector variant with internal recirculation. Straight 3,500 PSI clean water output for external chemical management.

Gymatic C2I Unloader — Two-Mode Wash Platform at 3,500 PSI

Factory-Matched. Adjustable. Integrated Chemical Feed. Set It and Run.

• Integrated downstream injection — the factory-integrated injector in the C2I assembly draws detergent, degreaser, or pre-soak solution when the operator switches to low-pressure application mode on the RKV35G35DF24C2I. No separate injector hardware or additional plumbing required.
• Two-mode workflow at 3.5 GPM / 3,500 PSI — chemical pre-soak breaks down grease, road film, and contamination; full 3,500 PSI / 3.5 GPM rinse removes loosened material at 12,250 cleaning units. Switch between modes without changing tools or equipment.
• Adjustable pressure regulation — dial in operating PSI for different nozzle sizes, surface types, and cleaning tasks. Supports quick transitions between detergent and rinse modes in the field.
• System protection — controlled bypass diverts flow safely at trigger release, protecting hoses, guns, and downstream accessories from pressure spikes throughout the RKV35G35DF24C2I operating range
• Simplified plumbing — integrated unloader and injector assembly reduces total fitting count, minimizing potential leak points and installation complexity on skid frames, trailers, and truck-mounted systems
• Injector maintenance — flush the injector circuit with clean water after every detergent session to preserve long-term venturi function as detailed in the included operator’s manual

Typical Applications
