RKV35G35D-F24C2 | 3.5 GPM 3500 PSI Triplex Pump Unloader Installed

RKV35G35D-F24C2 by Annovi Reverberi — RK Series Triplex Plunger Pump with Gymatic Unloader | 3.5 GPM | 3,500 PSI | Aluminum Crankcase | Oversized Bearings | Brass Manifold | 1″ Hollow Keyway Shaft | SAE J609A Gas and Diesel Engine Drive | No Chemical Injector

The RKV35G35D-F24C2 by Annovi Reverberi is a commercial and industrial RK Series triplex ceramic plunger pump engineered for direct gas and diesel engine-driven pressure washing systems requiring 3.5 GPM at 3,500 PSI with factory-matched Gymatic bypass pressure regulation and straight high-pressure water delivery. Rated at 3.5 GPM and 3,500 PSI at 3,400 RPM, the RKV35G35D-F24C2 delivers 12,250 cleaning units — combining 3.5 GPM focused output with 3,500 PSI cutting action for grease, mud, and embedded contaminants on fleet vehicles, construction equipment, agricultural machinery, and industrial surfaces — through a precision-balanced crankshaft supported by oversized bearings in a heavy-duty aluminum crankcase, solid ceramic plungers, precision-machined brass manifold, stainless steel valves, and an F24 SAE J609A direct-drive flange for close-coupling to gasoline or diesel engines.

The RKV35G35D-F24C2 is the no-injector Gymatic C2 configuration — straight 3,500 PSI water output for operators managing chemical delivery through a dedicated external downstream system. The factory-installed C2 adjustable bypass unloader provides immediate pressure control and protects the pump when the trigger gun is released, simplifying system setup right out of the box. Built by Annovi Reverberi in Modena, Italy — with US-based operations, a domestic parts distribution network, and dedicated AR North America technical support — the RKV35G35D-F24C2 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, this pump is a long-term investment capable of a decade of productive service life.

Factory-Matched and Approved — The RKV35G35D-F24C2 Complete Assembly Advantage

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

Every RKV35G35D-F24C2 ships as a factory-matched, factory-approved, and factory-installed complete pump and unloader assembly:

• Factory-matched C2 for 3,500 PSI — the C2 Gymatic bypass unloader is factory-calibrated for this pump’s 3.5 GPM / 3,500 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 RKV35G35D-F24C2 exits the AR manufacturing facility with the C2 unloader mounted, calibrated, and tested for flow, pressure, and leak-free operation before shipment.
• 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. The RKV35G35D-F24C2 arrives engineered, assembled, and ready.

Heavy-Duty Aluminum Crankcase with Oversized Bearings

Precision-Balanced Crankshaft. Oil-Bath Lubrication. Built for Continuous Duty.

The RKV35G35D-F24C2‘s heavy-duty aluminum crankcase with oversized bearings is a key construction differentiator at this pressure and flow point:

• Heavy-duty aluminum crankcase — aluminum construction provides excellent heat dissipation during continuous 3,500 PSI operation on the RKV35G35D-F24C2, helping manage operating temperatures across long daily duty cycles while keeping the overall assembly compact and lightweight
• Oversized bearings — larger bearing contact surfaces distribute the combined radial and axial loads of triplex plunger motion at 3,400 RPM more evenly, reducing unit bearing stress and extending bearing service intervals in high-cycle commercial environments
• Precision-balanced crankshaft — crankshaft balancing reduces vibration and rotational imbalance at operating speed, improving bearing life, seal geometry stability, and operator comfort during sustained maximum-output operation
• Oil-bath lubrication — continuous lubrication of crankshaft journals and bearings dissipates friction heat and maintains consistent film thickness across extended duty cycles on the RKV35G35D-F24C2

Gymatic C2 Unloader — Adjustable Bypass at 3,500 PSI

Factory-Approved. Adjustable. System Protection. Clean Water Output.

• Adjustable pressure regulation — dial in the ideal operating PSI for different nozzle sizes, surface types, and cleaning tasks on the RKV35G35D-F24C2 without changing hardware. Simple external adjustment supports a wide range of spray tips and accessories.
• System protection at trigger release — the C2 bypass unloader redirects excess flow safely when the trigger gun is released, preventing pressure spikes, overheating, and premature component wear throughout the RKV35G35D-F24C2 operating range
• No factory-installed injector — straight 3,500 PSI water output. Chemical delivery managed externally through a dedicated downstream injector or soft wash system when soap application is required.
• Compact factory-integrated assembly — pre-installed unloader simplifies system setup and ensures controlled pressure regulation right out of the box, reducing build time for OEM and replacement installations

Typical Applications

Where the RKV35G35D-F24C2 Delivers Best Results
