XTV3G16D-F7M2I by Annovi Reverberi — Triplex Plunger Pump with Gymatic Unloader and Chemical Injector | 3.0 GPM | 1,600 PSI | SAE J609A Direct Gas Engine Drive

The XTV3G16D-F7M2I by Annovi Reverberi is a commercial-grade triplex ceramic plunger pump built for gas engine-driven pressure washing systems that demand consistent water delivery, integrated chemical application capability, and a fully rebuildable platform engineered to last. Rated at 3.0 GPM and 1,600 PSI at 3,400 RPM, the XTV3G16D-F7M2I close-couples directly to gasoline engines via its F7 SAE J609A direct-drive flange — no adapter, no intermediate coupling, no alignment guesswork. This is a purpose-built gas engine pump that installs cleanly, performs consistently, and arrives complete with everything needed to go from the box to the job site.

Built by Annovi Reverberi in Modena, Italy — with US-based operations, a domestic parts distribution network, and dedicated AR North America technical support — the XTV3G16D-F7M2I ships as a fully factory-tested assembly. It is pre-filled with AR break-in oil, equipped with a Gymatic 3/B unloader and integrated downstream chemical injector, and packaged with mounting bolts and fasteners, a vented dipstick, operator’s manual, and full parts schematic. Backed by a 5-year US limited warranty through AR North America, this is a completely rebuildable platform capable of a decade of productive commercial service life with proper maintenance.

Decoding the XTV3G16D-F7M2I Model Number

What Every Segment of This AR Pump Designation Tells You

Annovi Reverberi encodes all critical specification data — performance output, shaft type, flange interface, unloader family, and injector configuration — directly into the pump model number. Reading the XTV3G16D-F7M2I correctly before installation confirms your engine compatibility, shaft engagement, and plumbing requirements up front:

• XTV — Pump series: XT Series triplex plunger pump with forged brass manifold construction
• 3G16 — Performance rating: 3.0 GPM flow rate at 1,600 PSI maximum operating pressure
• D — Shaft version: Direct Gas Drive — 3/4″ or 7/8″ hollow crankshaft for direct coupling to gasoline or diesel engine output shafts
• F7 — Flange type: SAE J609A direct-drive gas engine flange for SJV, XTV, RCV, and RCVU Series ‘D’ version pumps — designed for close coupling to engines with a 3/4″ cylindrical shaft (AR part AR1579)
• M2 — Unloader code: Gymatic (C2 = Gymatic per AR suffix designation) — Gymatic 3/B series internal bypass unloader, brass body, adjustable pressure regulation
• I — Chemical injector: Included — a downstream soap and chemical injector is integrated into the Gymatic unloader assembly, enabling low-pressure detergent application without a separate injector fitting

The F7 flange paired with the D shaft is a clean, purpose-matched combination. The F7 is AR’s SAE J609A direct-drive interface specifically engineered for gas engine installations — the pump mounts directly to the engine face and the hollow crankshaft bore engages the engine shaft without adapters or intermediate components. This is the straightforward gas-engine direct-drive configuration, contrasted with the F8 NEMA 56C electric motor face mount used on electric-drive XTV variants.

The “I” suffix confirms this pump includes an integrated fixed-rate downstream venturi injector built into the Gymatic unloader body, enabling operators to switch between high-pressure rinse and low-pressure detergent application through a single pump assembly. Operators who do not require integrated chemical feed should select the model variant without the “I” suffix.

F7 SAE J609A — Purpose-Built Gas Engine Direct Drive

Bolt Straight to the Engine. No Adapters. No Alignment Procedures.

The F7 flange on the XTV3G16D-F7M2I is AR’s direct-drive gas engine interface engineered specifically for XTV and related Series ‘D’ version pumps. It conforms to the SAE J609A standard used across the major commercial gasoline engine platforms found in pressure washing equipment — Honda, Kohler, Briggs and Stratton, Kawasaki, and others with a 3/4″ cylindrical output shaft:

• Direct close-coupling — the pump mounts face-to-face against the engine, with the hollow crankshaft bore engaging the engine shaft directly. No belt, jackshaft, or adapter is required in a standard direct-drive installation.
• SAE J609A standardization — the bolt pattern and shaft interface are consistent across engine brands, giving builders and operators broad engine sourcing flexibility without changing the pump
• Compact installation footprint — direct coupling eliminates the frame space consumed by belt guards, pulleys, and tensioning hardware, reducing overall skid and frame dimensions for portable rigs and trailer-mounted systems
• Efficient power transfer — direct shaft engagement delivers engine torque to the pump crankshaft with minimal drivetrain loss, particularly important at startup and under load spikes during production wash cycles
• Included mounting hardware — bolts and fasteners sized for the F7 SAE J609A bolt pattern are supplied in the box, eliminating a sourcing step at assembly

The Gymatic Unloader — Tamper-Resistant Pressure Control with Integrated Chemical Feed

Engineered for Rental Fleets, Managed Crews, and Set-and-Forget Operation

The Gymatic 3/B unloader (AR20399) on the XTV3G16D-F7M2I is rated to 3,650 PSI — well above this pump’s 1,600 PSI operating pressure. AR unloader ratings carry an accepted 15% upside variance, and pairing a higher-rated unloader with a lower-pressure pump is deliberate engineering practice: it widens the stable regulation window, reduces mechanical wear on unloader internals, and extends the service interval between rebuilds by operating the unloader well within its design envelope.

Once operating pressure is set and the adjustment locked, the Gymatic’s tamper-resistant design holds that setting reliably across every operator and every cycle — a characteristic that makes the XTV3G16D-F7M2I a strong specification for:

• Rental equipment fleets — pressure is dealer-configured once and maintained consistently across every rental, preventing user-induced over-pressure events and reducing service call frequency
• Managed cleaning and contractor crews — supervisors set pressure for the specific surface or application; crew members cannot inadvertently adjust settings between jobs or cause surface damage through over-pressurization
• Production wash operations — repeatable, locked pressure settings deliver consistent results job after job without drift or re-adjustment

The Gymatic 3/B also delivers:

• Internal bypass operation — when the spray trigger is released, water is smoothly redirected through the bypass circuit, preventing deadhead pressure spikes that accelerate seal and valve wear during trigger-off idle intervals
• Integrated downstream chemical injector — the venturi-driven injector built into the unloader body draws detergent, degreaser, or soap from a supply container when the operator switches to low-pressure application mode — no separate downstream injector assembly required on the XTV3G16D-F7M2I
• Engine load reduction in bypass — in trigger-off bypass mode, reduced system back-pressure lowers mechanical load on the engine, reducing fuel consumption and heat accumulation during idle intervals on long production wash days
• Brass body construction — resists corrosion from cleaning chemicals, chlorinated supply water, and sustained field exposure

Material Construction for Long-Term Commercial Service

Brass, Ceramic, and Stainless Steel — Every Wear Component Individually Rebuildable

The internal material specification of the XTV3G16D-F7M2I reflects Annovi Reverberi’s engineering approach: build every wear surface to last, and make every component individually replaceable so the pump platform outlives any single service event by years:

• Solid ceramic plungers resist the abrasive micro-wear of dissolved minerals, particulates, and the chemical solutions drawn through the downstream injector. Their hardness and dimensional stability far exceed stainless alternatives. When plungers eventually approach service limits they are replaced individually — the manifold, crankcase, and all other components remain in productive service.
• Forged brass manifold provides a dense, pore-free pressure vessel that withstands daily cyclic mechanical stress, thermal variance from gas engine heat environments, and sustained chemical exposure without the corrosion pitting and hairline cracking risk present in cast aluminum manifold designs under comparable conditions.
• Stainless steel valves maintain precise seating geometry through hundreds of thousands of pressure cycles, resisting the calcium scale accumulation and surface pitting that cause pressure loss and valve chatter in lesser materials.
• Triplex three-plunger design produces smooth, overlapping pressure pulses that measurably reduce pulsation-induced fatigue stress on hoses, spray guns, and quick-connect fittings compared to single or duplex pump configurations in high-cycle commercial use.

Typical Applications

Where the XTV3G16D-F7M2I Performs Best

The XTV3G16D-F7M2I’s gas engine direct-drive design, integrated chemical injector, tamper-resistant pressure control, and 3.0 GPM / 1,600 PSI output are well matched for:

• Pressure washing contractors — portable gas-engine rigs for residential and commercial exterior cleaning, surface restoration, and building maintenance with integrated detergent pre-treatment
• Rental equipment fleets — set-and-lock pressure, durable construction, and factory-tested reliability maximize rental-ready uptime between service intervals
• Fleet and vehicle washing operations — mobile trailer-mounted and truck-bed wash rigs for vehicles and service equipment at locations without electric service
• Agricultural operations — barn and facility washdowns, livestock equipment cleaning, and implement maintenance with combined pressure and detergent capability in field environments
• Municipal and government services — portable contractor rigs and maintenance vehicle-mounted systems for public infrastructure and fleet cleaning
• Construction and equipment cleaning — jobsite equipment, concrete forms, and tool washdowns combining pressure and degreaser application
• Property and facility maintenance contractors — storefronts, sidewalks, loading docks, and parking structures requiring regular combined pressure and chemical washing from portable gas-engine equipment
