XTV3G16D-F8M2I 3.0 GPM 1600 PSI Pump | 3400 RPM F8M2I

XTV3G16D-F8M2I by Annovi Reverberi — Triplex Plunger Pump with Gymatic Unloader and Chemical Injector | 3.0 GPM | 1,600 PSI | 3/4″ Hollow Crankshaft | NEMA 56C Electric or Gas Engine with 56C Flange Adapter

The XTV3G16D-F8M2I by Annovi Reverberi is a commercial-grade triplex ceramic plunger pump engineered for professional pressure washing systems that require consistent water delivery, integrated chemical application capability, and genuine drive flexibility. Rated at 3.0 GPM and 1,600 PSI at 3,400 RPM, the XTV3G16D-F8M2I is built around a 3/4″ hollow crankshaft and F8 NEMA 56C face-mount interface — a configuration that makes this pump directly compatible with NEMA 56C-frame electric motors and, with a standard 56C flange adapter, equally at home on a 3/4″ shaft gasoline engine. That dual-drive flexibility, combined with an integrated Gymatic unloader and downstream chemical injector, makes the XTV3G16D-F8M2I one of the most versatile pump platforms in its class.

Manufactured by Annovi Reverberi in Modena, Italy — with US-based operations, a domestic parts distribution network, and dedicated AR North America technical support — the XTV3G16D-F8M2I arrives as a complete, factory-tested assembly. It is pre-filled with AR break-in oil, mounted with a Gymatic 3/B unloader and integrated downstream chemical injector, and packaged with mounting hardware, a vented dipstick, operator’s manual, and full parts schematic. Every unit is factory load-tested before shipment and backed by a 5-year US limited warranty through AR North America.

Decoding the XTV3G16D-F8M2I Model Number

What Every Segment of This AR Pump Designation Tells You

Annovi Reverberi encodes all critical specification data — performance output, crankshaft bore, flange interface, unloader family, and injector configuration — directly into the pump model number. Reading the XTV3G16D-F8M2I correctly before installation ensures your drive source, motor or engine shaft, and plumbing configuration are all properly matched:

• 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 — Crankshaft bore: 3/4″ hollow crankshaft — accepts a 3/4″ shaft from a NEMA 56C-frame electric motor directly, or from a gasoline engine fitted with a standard 56C flange adapter
• F8 — Flange interface: NEMA 56C face-mount flange for XTV Series ‘D’ version pumps (AR part AR1584) — the pump’s round crankcase profile bolts directly to a 56C motor face or a 56C-adapted engine mount
• 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 D crankshaft and F8 flange combination is what gives this pump its drive flexibility. The XTV series pump crankcase is designed around a round-profile 56C face-mount interface. On electric motor installations, the pump bolts directly to the motor face and the 3/4″ motor shaft slides into the hollow crankshaft bore. On gasoline engine installations, a standard 56C flange adapter is fitted to the engine first, converting the engine output to a 56C face pattern — the pump then mounts identically to how it would on an electric motor, with the engine’s 3/4″ shaft engaging the same hollow bore. One pump, two drive sources, no proprietary hardware beyond the widely available 56C adapter.

Drive Flexibility — Electric Motor or Gas Engine

One Pump, Two Power Sources

The XTV3G16D-F8M2I’s 3/4″ hollow crankshaft and F8 NEMA 56C face-mount interface give builders and operators genuine installation flexibility without requiring different pump models for different power sources:

• NEMA 56C electric motor — direct mount: The pump bolts directly to the face of any standard NEMA 56C-frame electric motor running at 3,400 RPM. The motor’s 3/4″ shaft engages the hollow crankshaft bore, and the F8 face flange aligns and secures the assembly. No adapter, bracket, or intermediate coupling is required. This is the natural configuration for indoor wash bays, fixed wall-mount stations, and any installation where electric power is available and engine operation is restricted by noise, ventilation, or code requirements.
• Gasoline engine — 56C flange adapter: For portable rigs, trailer-mounted systems, and job sites without reliable electric service, the XTV3G16D-F8M2I installs on a gasoline engine by first fitting a standard 56C flange adapter to the engine’s output. The adapter converts the engine’s shaft interface to a 56C face pattern, and the pump then mounts and drives identically to the electric motor configuration. The 56C flange adapter is a widely available, off-the-shelf component compatible with most commercial-grade single-cylinder and twin-cylinder gasoline engines used in pressure washing equipment.

This architecture means a single XTV3G16D-F8M2I can be specified for both electric fixed-station and gas-engine portable builds — reducing inventory complexity for equipment builders and providing operators with a familiar, consistent pump platform across their equipment fleet regardless of power source.

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

Set It, Lock It, and Trust It Across Every Operator and Every Cycle

The Gymatic 3/B unloader (AR20399) on the XTV3G16D-F8M2I 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 deliberately pairing a higher-rated unloader with a lower-pressure pump is sound practice: it widens the stable pressure regulation window, reduces mechanical wear on unloader internals, and extends service intervals by operating the unloader well within its design envelope.

Once operating pressure is configured and the adjustment is locked, the Gymatic’s tamper-resistant design holds that setting reliably — making the XTV3G16D-F8M2I particularly well suited for:

• Rental equipment fleets — pressure is dealer-configured once and held consistently across every rental cycle, preventing user-induced over-pressure events and reducing service call frequency
• Managed cleaning crews — operations managers set pressure for the specific application; crew members cannot inadvertently adjust settings between jobs or damage surfaces through over-pressurization
• Fixed commercial wash stations — repeatable, consistent wash results across multiple shifts and operators are maintained without risk of pressure drift

Beyond tamper resistance, the Gymatic 3/B delivers:

• Internal bypass operation — trigger-off bypass smoothly redirects flow, preventing deadhead pressure spikes that accelerate seal and valve wear during idle intervals on both electric and gas-engine-driven systems
• 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
• Brass body construction — resists chemical corrosion, chlorinated supply water, and extended outdoor or indoor exposure

Material Construction for Decade-Long Commercial Service

Every Wear Component Individually Serviceable

The internal specification of the XTV3G16D-F8M2I is built for longevity and field serviceability across commercial duty cycles:

• Solid ceramic plungers resist abrasive micro-wear from dissolved minerals, particulates, and cleaning chemical solutions. Hardness and dimensional stability far exceed stainless alternatives, and when plungers eventually reach service limits they are replaced individually — the manifold, crankcase, and all other components remain in service.
• Forged brass manifold provides a dense, pore-free pressure vessel that withstands daily cyclic stress, thermal variance, and chemical exposure without the corrosion pitting and cracking risk of cast aluminum manifolds under sustained commercial use.
• Stainless steel valves maintain precise seating geometry through hundreds of thousands of pressure cycles, resisting calcium scale accumulation and the pitting that causes pressure loss and valve chatter in lesser materials.
• Triplex three-plunger design produces smooth, overlapping pressure pulses that reduce pulsation-induced fatigue on hoses, spray guns, and quick-connect fittings throughout the wash system.

Typical Applications

Where the XTV3G16D-F8M2I Performs Best

• Rental equipment fleets — tamper-resistant pressure control, durable construction, and factory-tested reliability maximize uptime between service intervals
• Indoor and covered electric wash bays — direct NEMA 56C motor mount, clean operation, integrated chemical feed for pre-soak and rinse workflows
• Portable gas-engine rigs — same pump platform used on gasoline engine frames via standard 56C flange adapter for job sites without electric service
• Managed commercial cleaning crews — locked pressure settings deliver repeatable results across multiple operators
• Fleet and vehicle washing stations — fixed or mobile wash points for cars, vans, light trucks, and service equipment
• Custom wash skid and frame builders — a single pump SKU that covers both electric and gas-engine builds simplifies procurement and inventory management
• Commercial property and facility maintenance — storefronts, parking areas, loading docks, and building exteriors requiring regular combined pressure and chemical washing
