RCA3G18E-F8M2I | Triplex Pump, 3.0 GPM 1800 PSI, F8 56C, M2 Unloader

RCA3G18E-F8M2I by Annovi Reverberi — Electric Triplex Plunger Pump with Mini-Matic M2I Unloader and Chemical Injector | 3.0 GPM | 1,800 PSI | Brass Manifold | 5/8″ Hollow Shaft | NEMA 56C F8 Electric Motor Mount | 1,750 RPM

The RCA3G18E-F8M2I by Annovi Reverberi is a professional-grade electric triplex ceramic plunger pump engineered for NEMA 56C electric motor-driven pressure washing systems requiring 3.0 GPM at 1,800 PSI with factory-integrated downstream chemical injection capability. Rated at 3.0 GPM and 1,800 PSI at 1,750 RPM, the RCA3G18E-F8M2I delivers 5,400 cleaning units — combining 3.0 GPM high-volume output with 1,800 PSI cleaning force for residential driveways, decks, patios, siding, commercial fleet washing, shop washdown stations, and agricultural machinery — through a brass manifold, solid ceramic plungers, stainless steel valves, heavy-duty bearings, and an F8 NEMA 56C flange with 5/8″ hollow shaft for direct coupling to compatible electric motors. As part of Annovi Reverberi’s pump and unloader assemblies stocked and supported by WSHPWR, the RCA3G18E-F8M2I arrives factory-configured and factory-tested, ready to deliver from the first startup.

The RCA3G18E-F8M2I carries the factory-installed Mini-Matic M2I integrated unloader and chemical injector — delivering precise, factory-set pressure regulation with downstream chemical injection from a single factory-configured, factory-approved assembly. Operating at 1,750 RPM, this pump delivers the thermal efficiency and extended component life of low-speed electric operation — running cooler, quieter, and with less internal wear than high-speed alternatives. 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 RCA3G18E-F8M2I is a long-term investment capable of a decade of productive service life.

Factory-Matched and Approved — The RCA3G18E-F8M2I Complete Assembly Advantage

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

Every RCA3G18E-F8M2I ships as a factory-matched, factory-approved, and factory-installed complete pump and unloader assembly:

• Factory-matched M2I for 1,800 PSI — the Mini-Matic M2I integrated unloader and chemical injector are factory-calibrated for this pump’s 3.0 GPM / 1,800 PSI duty point. Pressure regulation 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 RCA3G18E-F8M2I exits the manufacturing facility with the M2I 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.
• Installation-ready — confirm NEMA 56C motor compatibility, mount via the F8 flange, connect system hoses, connect the detergent supply line to the injector port, and start. The RCA3G18E-F8M2I arrives engineered, assembled, and ready.

1,750 RPM Low-Speed Electric Operation — Extended Component Life

Cooler. Quieter. Less Wear. Designed for Residential and Commercial Electric Systems.

• 1,750 RPM for reduced internal wear — the RCA3G18E-F8M2I operates at low speed compared to high-RPM alternatives, reducing heat buildup, vibration, and cumulative wear on ceramic plungers, seals, and bearings across residential and commercial cleaning cycles
• Quieter operation for indoor and residential environments — 1,750 RPM electric operation produces substantially lower noise than high-speed alternatives, suited for garage wash stations, enclosed shop areas, and residential settings where quiet operation matters
• Consistent voltage-regulated output — electric motor power delivers stable, consistent operating speed across all operating conditions, ensuring predictable 3.0 GPM flow and stable 1,800 PSI performance on the RCA3G18E-F8M2I
• Direct F8 NEMA 56C mount for quick installation — the RCA3G18E-F8M2I mounts directly to compatible NEMA 56C electric motors for fast installation, secure alignment, and efficient power transfer without belts or couplers

Mini-Matic M2I Unloader — Chemical Application and Rinse at 1,800 PSI

Factory-Set. Integrated Chemical Feed. Safe Pressure Control.

• Precise factory-set pressure regulation — the Mini-Matic M2I on the RCA3G18E-F8M2I arrives calibrated for immediate 1,800 PSI operation, providing safe and consistent pressure for residential and light commercial surface cleaning
• Integrated downstream injection — draws detergent or pre-soak solution when the operator switches to low-pressure application mode. No separate injector hardware required on the RCA3G18E-F8M2I.
• Chemical application and rinse at 3.0 GPM / 1,800 PSI — chemical pre-soak breaks down contamination; full 1,800 PSI / 3.0 GPM rinse removes loosened material at 5,400 cleaning units. Switch between application and rinse without changing tools.
• Safe bypass protection — the M2I unloader reduces pump strain and protects against over-pressurization on the RCA3G18E-F8M2I, improving both safety and long-term pump longevity during stop-and-go cleaning cycles
• Injector maintenance — flush the M2I injector circuit with clean water after every detergent session to preserve long-term venturi function on the RCA3G18E-F8M2I

Typical Applications
