Built by Annovi Reverberi in Modena, Italy — a globally recognized manufacturer with US-based operations, domestic parts distribution, and a dedicated North American support network — the XTV3G22D-F7M2I ships as a complete, factory-tested assembly. It arrives 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 parts schematic. Every unit is load-tested at the factory before shipment and protected by a 5-year US limited warranty through AR North America.

Decoding the XTV3G22D-F7M2I Model Number

What Every Segment of This AR Pump Designation Tells You

Annovi Reverberi encodes all critical performance, shaft, flange, unloader, and injector data directly into the pump model number. Knowing how to read it ensures you select the correct pump and verify its configuration before installation:

• XTV — Pump series: XT Series triplex plunger pump with forged brass manifold construction
• 3G22 — Performance rating: 3.0 GPM flow rate at 2,200 PSI maximum operating pressure
• D — Shaft version: Direct Gas Drive — compatible with 3/4″ or 7/8″ hollow shaft gasoline or diesel engines
• 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″ I.D. cylindrical shaft (AR part AR1579)
• M2 — Unloader code: Gymatic (C2 = Gymatic per AR suffix designation) — Gymatic 3/B series internal bypass unloader with adjustable pressure regulation and brass body construction
• 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 “I” at the end of this model number is a specification detail that directly affects how you plumb and operate the system. It confirms a fixed-rate downstream chemical injector is built into the Gymatic unloader, allowing operators to draw detergent or degreaser from a supply container during the low-pressure rinse cycle. If your application does not require integrated chemical feed, the model variant without the “I” suffix is the correct selection.

The F7 SAE J609A Gas Engine Flange

Direct-Drive Simplicity for Gas and Diesel Engine Systems

The F7 flange on the XTV3G22D-F7M2I is an AR-engineered close-coupling interface designed specifically for XTV and related Series ‘D’ version pumps paired with gasoline or diesel engines equipped with a 3/4″ cylindrical drive shaft and SAE J609A bolt pattern. This direct-drive configuration offers several practical advantages over belt or jackshaft-driven alternatives:

• No alignment guesswork — the pump and engine connect face-to-face on a common SAE J609A interface, ensuring concentric shaft alignment without adjustment procedures
• Compact installation footprint — direct coupling eliminates the frame space required for belt guards, pulleys, and tensioning hardware, reducing the overall skid or frame dimensions
• Reduced drivetrain losses — direct coupling transmits engine power to the pump more efficiently than belt drives, particularly at startup and under load spikes
• Broad engine compatibility — the F7 SAE J609A standard is used across major gas engine manufacturers, making this pump compatible with a wide range of Honda, Kohler, Briggs and Stratton, and similar commercial-grade engine platforms
• Included hardware — mounting bolts and fasteners sized for the F7 bolt pattern are supplied in the box, eliminating a sourcing step during assembly

The Gymatic Unloader and Integrated Chemical Injector

Pressure Regulation and Detergent Feed in a Single Assembly

The Gymatic 3/B unloader installed on the XTV3G22D-F7M2I is AR’s internal bypass unloader platform used across the RR, XM, and RK series pump families — a proven design rated to 3,650 PSI and flow ranges from 3 to 4 GPM. On this pump, the Gymatic unloader delivers:

• Internal bypass pressure regulation — when the spray trigger is released, water is redirected through the bypass circuit rather than building deadhead pressure in the manifold, protecting seals, valves, and downstream fittings
• Adjustable operating pressure — on-site pressure tuning via the unloader adjustment allows operators to dial in working pressure for different surfaces, nozzles, and application requirements
• Integrated downstream chemical injector — the “I” suffix confirms a fixed-rate venturi-driven downstream injector is built directly into the unloader body, drawing soap, degreaser, or detergent at a controlled ratio when the operator switches to the low-pressure application mode
• Brass body durability — the unloader body resists corrosion from cleaning chemicals, chlorinated water, and outdoor exposure across years of service
• Engine protection during bypass — in idle-bypass mode, reduced system back-pressure lowers the mechanical load on the engine, reducing fuel consumption and heat buildup during trigger-off intervals on production wash jobs

The venturi injector operates without powered dosing equipment — no chemical pump, metering system, or electrical supply is needed. When the operator reduces pressure for detergent application, the pressure differential across the injector draws chemical from a supply container at the factory-set injection ratio. After detergent application, switching back to high-pressure rinse automatically closes the injector. This makes the XTV3G22D-F7M2I a complete two-mode wash platform from a single, self-contained pump assembly.

Construction Materials and Long-Term Service Life

Built to Be Rebuilt — Not Replaced

The internal material specification of the XTV3G22D-F7M2I reflects AR’s engineering philosophy: build a pump that outlasts the job, and make every wear component individually serviceable:

• Solid ceramic plungers provide hardness ratings well beyond stainless steel alternatives, resisting the abrasive micro-wear caused by dissolved minerals, particulates, and the chemical solutions drawn through the downstream injector. When plungers eventually approach service limits, they are individually replaceable — the manifold, crankcase, and all other components are retained.
• Forged brass manifold eliminates the micro-porosity risk inherent in cast aluminum, delivering a dense pressure vessel that withstands the cyclic stress, thermal variance, and chemical exposure of commercial duty cycles without developing the corrosion pitting and hairline cracks that shorten cast manifold service life.
• Stainless steel valves maintain precise seating geometry across hundreds of thousands of pressure cycles, resisting calcium scale accumulation and the surface pitting that causes premature valve leakage and pressure loss in lesser materials.
• Triplex three-plunger design inherently produces smoother, more overlapping pressure pulses than single or duplex configurations, reducing pulsation-induced fatigue stress on hoses, spray guns, and quick-connect fittings throughout the system.
