RKV35G33DAFC2I | 3.0 GPM 3300 PSI Triplex Pump Unloader Installed

RKV35G33DAFC2I by Annovi Reverberi — RK Series Triplex Plunger Pump with AF C2I Unloader and Chemical Injector | 3.0 GPM | 3,300 PSI | Bronze Connecting Rods | Brass Manifold | 1″ Hollow Keyway Shaft | Direct Gas Drive

The RKV35G33DAFC2I by Annovi Reverberi is a professional-grade RK Series triplex ceramic plunger pump engineered for gas engine-driven commercial, contractor, and industrial pressure washing systems requiring 3.0 GPM at 3,300 PSI with integrated downstream chemical application capability. Rated at 3.0 GPM and 3,300 PSI at 3,400 RPM, the RKV35G33DAFC2I delivers 9,900 cleaning units — combining 3.0 GPM flow with 3,300 PSI cutting pressure for heavy grime, grease, and contaminants on fleet vehicles, construction equipment, agricultural machinery, and industrial surfaces — through an anodized aluminum crankcase with bronze connecting rods, solid ceramic plungers, precision-machined brass manifold, stainless steel valves, and a 1″ hollow keyway shaft for direct coupling to compatible gas engines.

The RKV35G33DAFC2I carries the AF C2I integrated unloader and chemical injection system — factory-installed as a complete assembly that combines adjustable bypass pressure regulation with on-demand downstream chemical injection, simplifying system plumbing, reducing external components, and delivering the two-mode wash platform from a single factory-configured unit. 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 RKV35G33DAFC2I is a long-term investment capable of a decade of productive service life.

Factory-Matched and Approved — The RKV35G33DAFC2I Complete Assembly Advantage

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

Every RKV35G33DAFC2I ships as a factory-matched, factory-approved, and factory-installed complete pump and unloader assembly:

• Factory-matched AF C2I for 3,300 PSI — the AF C2I integrated unloader and injector are factory-calibrated for this pump’s specific 3.0 GPM / 3,300 PSI duty 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 RKV35G33DAFC2I exits the AR manufacturing facility with the AF C2I 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.

AF C2I Integrated Unloader — Two-Mode Platform at 3,300 PSI

Factory-Approved. Adjustable Bypass. Integrated Chemical Feed. Simplified Plumbing.

• Integrated bypass and injection in a single assembly — the AF C2I on the RKV35G33DAFC2I combines adjustable bypass pressure regulation and downstream chemical injection in one factory-installed unit, eliminating the need for separate external injectors and reducing total fitting count and potential leak points
• Adjustable C2 bypass unloader — regulates system pressure by diverting excess flow when the trigger gun is released, reducing shock loads and extending component life across continuous cleaning operations
• Downstream chemical injection — draws detergent or cleaning solution into the water stream when the operator switches to low-pressure application mode on the RKV35G33DAFC2I. Consistent chemical application without external injector hardware.
• Two-mode workflow at 3.0 GPM / 3,300 PSI — chemical pre-soak breaks down grease, road film, and contamination; full 3,300 PSI / 3.0 GPM rinse removes loosened material. Switch between modes without changing tools.
• Improved efficiency and reduced downtime — integrated design speeds setup, simplifies troubleshooting, and supports faster transitions between detergent and rinse modes in the field on the RKV35G33DAFC2I
• Injector maintenance — flush the injector circuit with clean water after every detergent session to preserve long-term venturi function

Construction — Bronze Rods, Ceramic Plungers, Brass Manifold, Anodized Aluminum Crankcase

Premium Materials for Continuous Commercial Duty at 3,300 PSI

• Bronze connecting rods on the RKV35G33DAFC2I driven by a balanced crankshaft supported by heavy-duty bearings ensure smooth power transfer and reduced vibration at 3,400 RPM across extended commercial duty cycles
• Solid ceramic plungers operate cooler than steel alternatives, reducing seal wear and extending maintenance intervals. Precision-ground for consistent reciprocating motion and long-term dimensional stability.
• Precision-machined brass manifold provides excellent corrosion resistance, pressure fatigue resistance, and thermal stability while maintaining precise sealing surfaces for long service life
• Stainless steel valves manage intake and discharge flow with accuracy and reliability, maintaining consistent 3,300 PSI pressure while resisting wear and chemical exposure
• Anodized aluminum crankcase with oil-bath lubrication provides a compact, lightweight housing that dissipates heat efficiently during continuous operation on the RKV35G33DAFC2I, protecting moving parts from friction and wear
