RKV35G30AF24C1I 3.5 GPM 3000 PSI Triplex Pump | 3400 RPM

RKV35G30AF24C1I by Annovi Reverberi — RK Series Triplex Plunger Pump with Gymatic VR35 Unloader and Chemical Injector | 3.5 GPM | 3,000 PSI | Forged Brass Manifold | 1″ Hollow Keyway Shaft | SAE J609A Gas and Diesel Engine Drive

The RKV35G30AF24C1I 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 3,000 PSI with the elevated bypass regulation of the Gymatic VR35 unloader and factory-integrated downstream chemical injection. Rated at 3.5 GPM and 3,000 PSI at 3,400 RPM, the RKV35G30AF24C1I delivers 10,500 cleaning units — combining 3.5 GPM flow with 3,000 PSI cleaning force for grease, oil, mud, and surface contaminants on fleet vehicles, agricultural equipment, concrete surfaces, and industrial applications — through solid ceramic plungers, a forged brass manifold, stainless steel check valves, and an F24 SAE J609A direct-drive flange for compact, belt-free coupling to gasoline or diesel engines.

The RKV35G30AF24C1I carries the C1 unloader designation — confirming the Gymatic VR35 (AR22287), AR’s elevated-capacity Gymatic unloader rated to 4,000 PSI and 5 GPM. At 3,000 PSI the VR35 provides a full 1,000 PSI of operating headroom — the most generous unloader margin in this entire product library — delivering maximum bypass stability and the longest unloader service intervals at this pressure point. Combined with the factory-integrated I-series downstream chemical injector, the RKV35G30AF24C1I delivers the complete two-mode wash platform from a single factory-configured, factory-approved assembly.

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 RKV35G30AF24C1I is a long-term investment capable of a decade of productive service life.

Factory-Matched and Approved — The RKV35G30AF24C1I Complete Assembly Advantage

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

Every RKV35G30AF24C1I ships as a factory-matched, factory-approved, and factory-installed complete pump and unloader assembly:

• Factory-matched VR35 and injector for 3,000 PSI — the C1I assembly on the RKV35G30AF24C1I is factory-calibrated for this pump’s 3.5 GPM / 3,000 PSI duty point. VR35 bypass response, pressure regulation, and chemical injector 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 RKV35G30AF24C1I exits the AR manufacturing facility with the C1I assembly mounted, calibrated, and tested for flow, pressure, and leak-free operation before shipment.
• Eliminates mismatch returns — the factory-matched assembly eliminates incorrect unloader or injector 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, connect the detergent supply line to the injector port, add fuel, and start. Ready from day one.

Decoding the RKV35G30AF24C1I 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
• 30 — Maximum pressure: 3,000 PSI — 3.5 × 3,000 = 10,500 cleaning units
• 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)
• C1 — Unloader variant: Gymatic VR35 (AR22287) — rated to 4,000 PSI and 5 GPM. At 3,000 PSI the VR35 provides 1,000 PSI of operating headroom — the most generous margin in this product library, delivering maximum bypass stability and extended unloader service intervals.
• I — Chemical injector: Included — downstream soap and chemical injector factory-integrated into the Gymatic VR35 assembly, enabling low-pressure detergent application without a separate injector fitting

Gymatic VR35 C1I — 1,000 PSI Headroom. Maximum Stability. Two-Mode Platform.

The Most Generous Unloader Margin in This Library. Factory-Approved. Integrated Chemical Feed.

• 1,000 PSI headroom — widest margin in this product library — the VR35 at 3,000 PSI operates 25% below its rated ceiling on the RKV35G30AF24C1I, producing the most stable, predictable bypass regulation available at this pressure point. Every trigger release is smooth and consistent, protecting hoses, guns, and accessories throughout continuous operation.
• Longest unloader service intervals — VR35 bypass components operating with 1,000 PSI of headroom experience minimal cumulative stress across high-cycle commercial operation, extending rebuild intervals significantly compared to tighter pairings
• Integrated downstream injection — the factory-integrated injector draws detergent or pre-soak solution when the operator switches to low-pressure application mode. No separate injector hardware or additional plumbing required on the RKV35G30AF24C1I.
• Two-mode workflow — chemical pre-soak breaks down grease, road film, and contamination; full 3,000 PSI / 3.5 GPM rinse removes loosened material at 10,500 cleaning units. Switch between modes without changing tools.
• Integrated soap injection — simplifies system plumbing, reduces external components, and allows detergent application without downstream injector hardware. Especially beneficial for mobile operators who need a clean, compact setup.
• Injector maintenance — flush the injector circuit with clean water after every detergent session to preserve long-term venturi function

Typical Applications

Where the RKV35G30AF24C1I Delivers Best Results

• Commercial pressure washing and contract cleaning — building exteriors, concrete surfaces, and vehicle washing where the RKV35G30AF24C1I’s two-mode capability and VR35 stable pressure regulation deliver consistent professional results
• Fleet washing for trucks, buses, and service vehicles — integrated detergent injection and 3,000 PSI cleaning force handle road film and grease efficiently without separate downstream hardware
• Agricultural equipment and facility washdown — tractors, implements, and farm facilities where on-demand chemical capability and 3.5 GPM output handle varied agricultural contamination on gas or diesel engine-powered rigs
• Industrial maintenance and general wash applications — the RKV35G30AF24C1I’s two-mode output and accessible service design support both chemical degreasing and high-pressure rinsing from a single factory-matched assembly
• Portable, cart-mounted, and trailer-mounted pressure washers — compact F24 direct-drive footprint and factory-matched C1I assembly support efficient integration into portable and mobile professional pressure washer systems

For operators who prefer a fully configured direct-drive system rather than a bare pump assembly, WSHPWR also carries complete gas and diesel engine pump packages ready to mount on a frame or trailer.
