RKV35G35D-MC2I | 3.5 GPM 3500 PSI Triplex Pump Unloader Installed

RKV35G35D-MC2I by Annovi Reverberi — RK Series Triplex Plunger Pump with MC2I Unloader and Chemical Injector | 3.5 GPM | 3,500 PSI | Bronze Connecting Rods | 1″ Hollow Keyway Shaft | Direct Gas Drive | 8–13 HP Engine Compatible

The RKV35G35D-MC2I by Annovi Reverberi is a commercial-grade RK Series triplex ceramic plunger pump engineered for direct gas engine-driven 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, this pump delivers 12,250 cleaning units through a reinforced crankcase with bronze connecting rods, solid ceramic plungers, brass manifold, precision-machined valves, and a 1″ hollow keyway shaft for direct coupling to 8–13 HP gasoline engines.

The RKV35G35D-MC2I carries the factory-installed MC2I adjustable unloader with integrated downstream chemical injector — simplifying system assembly, reducing external fitting count, and delivering the complete two-mode wash platform from a single factory-configured assembly. Sized for the 8–13 HP small gas engine class, the RKV35G35D-MC2I is an efficient choice for portable pressure washer units, OEM builds, commercial contractors, and industrial operations where a capable triplex pump without belt-drive complexity is the right specification.

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-MC2I arrives as a complete, factory-tested assembly. Pre-filled with AR break-in oil, equipped with the factory-matched MC2I unloader and active downstream chemical injector, and packaged with mounting bolts and fasteners, a vented dipstick, operator’s manual, and full parts schematic, this pump is ready to install from the moment it arrives. Protected by a 5-year US limited warranty through AR North America and built to be fully rebuilt rather than replaced, the RKV35G35D-MC2I is a long-term investment capable of a decade of productive service life.

Factory-Matched and Approved — The RKV35G35D-MC2I Complete Assembly Advantage

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

The RKV35G35D-MC2I ships as a factory-matched, factory-approved, and factory-installed complete pump and unloader assembly:

• Factory-matched MC2I for 3,500 PSI — the MC2I unloader and integrated injector on the RKV35G35D-MC2I are factory-calibrated for this pump’s specific duty point as a complete system, not assembled from separately sourced components in the field.
• Factory-approved configuration — operating with the factory-installed components maintains full 5-year warranty coverage. Substituting the factory-installed unloader or injector voids warranty protection.
• Factory-installed and tested — every RKV35G35D-MC2I exits the AR manufacturing facility with the MC2I assembly mounted, calibrated, and tested before shipment. No field calibration from scratch.
• Eliminates component mismatch returns — incorrect unloader specification is the most common source of pump 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, connect the detergent supply line to the injector port, add fuel, and start. Ready from day one.

MC2I Unloader — Two-Mode Wash Platform at 3,500 PSI

Factory-Matched. Adjustable. Integrated Chemical Feed. Pre-Set for Immediate Use.

• Factory pre-set for immediate use — reduces installation time and ensures proper setup for safe, reliable operation from first startup. No external unloader plumbing, no injector sourcing, no adjustment from scratch.
• Integrated downstream injection — draws detergent or pre-soak solution from a supply container when the operator switches to low-pressure application mode. No separate injector hardware required.
• Two-mode workflow — 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.
• Adjustable pressure regulation — fine-tune working pressure for different nozzle sizes, surface types, and cleaning tasks without changing hardware
• Simplified plumbing — compact factory-integrated assembly reduces the total fitting count, lowering potential leak points and simplifying troubleshooting
• Injector maintenance — flush the injector circuit with clean water after every detergent session to preserve long-term venturi function

Typical Applications

Where the RKV35G35D-MC2I Delivers Best Results

— factory-integrated two-mode capability simplifies daily operations across building exteriors, concrete surfaces, vehicle washing, and commercial cleaning

• Industrial equipment and facility cleaning — degreasing and washdown where integrated injection delivers chemical pre-treatment without additional hardware
• Agricultural machinery washdown — tractors and implements on gas engine-powered rigs in the 8–13 HP operating range
• Fleet and vehicle maintenance — trucks, vans, and service vehicles where integrated chemical application and 3,500 PSI cleaning force handle road film and grease efficiently
• Portable units and OEM manufacturing — compact direct-drive design, factory-matched MC2I assembly, and 8–13 HP engine compatibility make this a practical platform for portable systems, rental-ready skids, and OEM production builds

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.
