RKA4G30E-F17C2I Electric Triplex Pump | 4.0 GPM 3000 PSI

RKA4G30E-F17C2I by Annovi Reverberi — Electric Triplex Plunger Pump with Gymatic C2I Unloader and Chemical Injector | 4.0 GPM | 3,000 PSI | Forged Brass Head | 1-1/8″ Hollow Shaft | NEMA 182/184 F17 Electric Motor Mount | 1,750 RPM

The RKA4G30E-F17C2I by Annovi Reverberi is a professional-grade RKA Series industrial triplex ceramic plunger pump engineered specifically for NEMA 182/184 electric motor-driven pressure washing systems requiring 4.0 GPM at 3,000 PSI with factory-integrated downstream chemical injection capability. Rated at 4.0 GPM and 3,000 PSI at 1,750 RPM, the RKA4G30E-F17C2I delivers 12,000 cleaning units — combining 4.0 GPM high-volume output with 3,000 PSI cleaning force for stationary wash bays, mobile electric contractor rigs, commercial fleet systems, industrial surfaces, agricultural equipment, and facility maintenance — through a forged brass head, solid ceramic plungers, stainless steel valves, and an F17 NEMA 182/184 flange with 1-1/8″ hollow shaft for rigid direct coupling to compatible electric motors.

The RKA4G30E-F17C2I carries the factory-installed bolt-on Gymatic C2I adjustable unloader with integrated downstream soap injection — delivering the complete two-mode wash platform from a single factory-configured, factory-approved assembly with an adjustment range from 200 PSI up to full operating pressure. Operating at 1,750 RPM on an electric motor platform, the RKA4G30E-F17C2I runs cooler and quieter than high-speed alternatives, extending seal, plunger, and bearing service intervals across continuous-duty stationary and mobile wash environments. Built by Annovi Reverberi in Modena, Italy — with US-based operations, a domestic parts distribution network, and dedicated technical support — this pump arrives pre-filled with factory break-in oil, factory-tested, and ready for installation. Protected by a 5-year US limited warranty and built to be fully rebuilt rather than replaced, the RKA4G30E-F17C2I is a long-term industrial investment capable of a decade of productive service life.

Factory-Matched and Approved — The RKA4G30E-F17C2I Complete Assembly Advantage

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

Every RKA4G30E-F17C2I ships as a factory-matched, factory-approved, and factory-installed complete pump and unloader assembly:

• Factory-matched C2I for 3,000 PSI — the bolt-on Gymatic C2I unloader and integrated injector are factory-calibrated for this pump’s 4.0 GPM / 3,000 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 Annovi Reverberi’s validated specification for this model. Operating with the factory-installed components maintains full 5-year warranty coverage.
• Factory-installed and tested — every RKA4G30E-F17C2I exits the 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 incorrect unloader or injector specification — the most common source of industrial pump system returns — before the pump leaves the box.
• Installation-ready — confirm NEMA 182/184 motor compatibility, mount via the F17 flange, connect system hoses, connect the detergent supply line to the injector port, and start. The RKA4G30E-F17C2I arrives engineered, assembled, and ready.

F17 NEMA 182/184 Electric Motor Platform — Rigid Direct Coupling at 1,750 RPM

Direct Electric Motor Coupling. Low-Speed Operation. Stationary and Mobile System Ready.

• F17 flange with NEMA 182/184 interface — the RKA4G30E-F17C2I mounts rigidly to compatible NEMA 182/184 electric motors via the F17 flange and 1-1/8″ hollow shaft, providing a compact, direct motor-to-pump connection without belts, pulleys, or intermediate couplings. Confirm motor compatibility before installation.
• 1,750 RPM low-speed electric operation — running at significantly lower speed than high-RPM alternatives, the RKA4G30E-F17C2I reduces internal friction, heat generation, and stress on ceramic plungers, seals, and bearings across continuous industrial duty cycles
• Consistent voltage-regulated output — electric motor power delivers stable, consistent operating speed unaffected by fuel quality, ambient temperature, or altitude, ensuring predictable 4.0 GPM flow and stable 3,000 PSI performance on the RKA4G30E-F17C2I across all operating conditions
• Reduced facility noise levels — 1,750 RPM electric operation produces substantially lower acoustic output than high-speed engine alternatives, relevant for indoor wash bays, service facilities, and enclosed industrial environments where noise compliance matters
• Turnkey package for faster commissioning — direct electric motor coupling, integrated C2I unloader, and factory-tested assembly reduce component sourcing, eliminate belt alignment work, and shorten build time for new stationary and mobile electric pressure washer installations

C2I Bolt-On Unloader — Two-Mode Platform at 3,000 PSI

200 PSI to Maximum. Integrated Chemical Feed. Factory-Approved.

• 200 PSI to maximum pressure adjustment range — the C2I bolt-on assembly on the RKA4G30E-F17C2I provides wide adjustable control from low-pressure detergent application to full 3,000 PSI rinsing output, supporting varied surface types and cleaning tasks
• Integrated downstream injection — draws detergent or cleaning solution when the operator switches to low-pressure application mode. No separate injector hardware or additional plumbing required on the RKA4G30E-F17C2I.
• Two-mode workflow at 4.0 GPM / 3,000 PSI — chemical pre-soak breaks down grease, road film, and facility contamination; full 3,000 PSI / 4.0 GPM rinse removes loosened material at 12,000 cleaning units. Switch between modes without changing tools.
• Internal bypass for controlled trigger cycling — smooth bypass at trigger release protects the RKA4G30E-F17C2I and downstream accessories from pressure spikes, supporting safe, stable set-pressure operation throughout industrial cleaning programs
• Simplified system layout — all-in-one bolt-on C2I assembly reduces plumbing complexity, shortens setup time, and supports faster commissioning of stationary wash bay and mobile electric contractor installations
• Injector maintenance — flush the injector circuit with clean water after every detergent session and keep inlet strainers clean to protect valves and packings

Typical Applications

Where the RKA4G30E-F17C2I Delivers Best Results

• Mobile contractor pressure washing rigs using electric power — the RKA4G30E-F17C2I’s F17 NEMA 182/184 interface, factory-matched C2I assembly, and 1,750 RPM electric operation support reliable performance across varied commercial cleaning accounts on electric-powered contractor systems
• Commercial fleet and equipment washing — integrated chemical injection and 3,000 PSI / 4.0 GPM output handle fleet vehicle contamination efficiently in production wash bay environments powered by electric motors
• Industrial surface cleaning, degreasing, and facility maintenance — stationary NEMA-coupled installations where the RKA4G30E-F17C2I’s two-mode capability and continuous-duty construction support multi-shift production washdown programs
• Agricultural and farm equipment washdown — on-demand detergent capability and 4.0 GPM output handle agricultural contamination in electric-powered stationary wash installations
• Stationary wash bays requiring an integrated pump, unloader, and injector — the RKA4G30E-F17C2I’s F17 NEMA 182/184 motor interface, factory-matched C2I assembly, and turnkey configuration make it the purpose-engineered specification for fixed facility electric wash systems
