XMV3G27D-F25M2 3.0 GPM 2700 PSI Pump | 3400 RPM F25M2

XMV3G27D-F25M2 by Annovi Reverberi — Triplex Plunger Pump with Gymatic Unloader | 3.0 GPM | 2,700 PSI | 3/4″ Shaft | SAE J609A Gas and Diesel Engine Drive | No Chemical Injector

The XMV3G27D-F25M2 by Annovi Reverberi is a commercial-grade triplex ceramic plunger pump engineered for gas and diesel engine-driven pressure washing systems that operate at 2,700 PSI with dependable Gymatic bypass pressure control — without an integrated downstream chemical injector. Rated at 3.0 GPM and 2,700 PSI at 3,400 RPM, the XMV3G27D-F25M2 is built around a 3/4″ hollow shaft and F25 SAE J609A direct-drive flange — close-coupling directly to the class of gasoline and diesel engines most common on contractor pressure washer frames and portable wash rigs without adapters or intermediate couplings. This is the clean, straight-pressure configuration of the XMV3G27D-F25 platform — the correct specification for operators who manage chemical delivery through a dedicated external injector, soft wash system, or not at all.

Built by Annovi Reverberi in Modena, Italy — with US-based operations, a domestic parts distribution network, and dedicated AR North America technical support — the XMV3G27D-F25M2 arrives as a complete, factory-tested assembly. Pre-filled with AR break-in oil, equipped with a Gymatic unloader for internal bypass pressure regulation, and packaged with mounting bolts and fasteners, a vented dipstick, operator’s manual, and full parts schematic, this pump is ready to install from the moment it arrives. Protected by a 5-year US limited warranty through AR North America and built to be fully rebuilt rather than replaced, the XMV3G27D-F25M2 is a long-term investment in a high-pressure pump platform capable of a decade of productive commercial service life.

Decoding the XMV3G27D-F25M2 Model Number

What Every Segment of This AR Pump Designation Tells You

Annovi Reverberi encodes all critical specification data — pump series, performance output, shaft type, flange interface, unloader family, and injector configuration — directly into the model number. Reading the XMV3G27D-F25M2 correctly before specifying or installing confirms engine compatibility, shaft bore, pressure rating, and chemical feed status:

• XMV — Pump series: XM Series triplex plunger pump — AR’s commercial high-pressure platform with forged brass manifold construction, engineered for sustained 2,700–3,000 PSI operation
• 3G27 — Performance rating: 3.0 GPM flow rate at 2,700 PSI maximum operating pressure
• D — Shaft version: Direct Gas/Diesel Drive — 3/4″ hollow shaft for direct coupling to gasoline or diesel engine output shafts in the compact contractor engine class
• F25 — Flange type: SAE J609A direct-drive flange for XM Series ‘D’ version pumps — close coupling to gas or diesel engines with a 3/4″ cylindrical shaft (AR part AR1780580), the standard interface for Honda GX390, Kohler CH395, Briggs and Stratton Vanguard, and comparable 3/4″ shaft engines on contractor pressure washer frames
• M2 — Unloader code: Gymatic (M2 = C2 = Gymatic per AR suffix designation) — Gymatic series internal bypass unloader, brass body, adjustable pressure regulation, factory-fitted
• No trailing suffix — the model terminates at M2 with no “I” following, confirming the Gymatic unloader is fitted without a downstream chemical injector port. This pump delivers straight high-pressure water output. Operators requiring integrated chemical feed should select the XMV3G27D-F25M2I.

XMV3G27D-F25M2 vs XMV3G27D-F25M2I — One Suffix Character, One Critical Difference

These two pumps are identical in XM Series construction, F25 flange, shaft bore, and Gymatic unloader family. The single operative difference is injector configuration:

• XMV3G27D-F25M2 — Gymatic unloader fitted, no chemical injector. Correct for systems using a dedicated external downstream injector, soft wash chemical delivery, proportioner, or straight water pressure applications where chemical feed through the pump is not required.
• XMV3G27D-F25M2I — Gymatic unloader fitted with integrated downstream chemical injector active. Correct for operators who want a self-contained two-mode assembly — high-pressure rinse and low-pressure detergent pre-soak — without additional injector hardware.

Confirming the correct variant before ordering ensures your chemical delivery architecture matches the pump configuration you receive and avoids a return.

The Gymatic Unloader — Tamper-Resistant 2,700 PSI Pressure Control

Configured for External or No Chemical Feed — Stable Bypass at Full Commercial Pressure

The Gymatic unloader (M2) on the XMV3G27D-F25M2 is rated above the pump’s 2,700 PSI operating pressure — within AR’s accepted 15% upside variance for unloader pairings. Operating the Gymatic within its rated range widens the stable regulation window, reduces internal wear, and extends the rebuild interval by keeping the unloader well within its design envelope throughout the pump’s service life.

On the XMV3G27D-F25M2, the Gymatic is configured without a downstream chemical injector, making it the correct specification for:

• Systems with dedicated external downstream injectors — operators who prefer a separate, independently adjustable downstream injector for precise ratio control rather than a fixed venturi injector built into the unloader body
• Soft wash and proportioner systems — chemical delivery managed by a dedicated proportioning pump, batch tank, or metering system where injection ratio requirements exceed what a fixed venturi provides
• Straight water pressure applications — concrete cleaning, surface prep, fleet washing, and industrial washdowns where detergent is pre-applied, handled externally, or not required
• OEM integrators and rig builders standardizing chemical delivery — system builders who specify injector type, ratio, and placement independently from the pump across multiple rig configurations

Once pressure is set and locked, the Gymatic’s tamper-resistant design holds that setting reliably:

• Tamper-resistant once set — locked pressure is maintained consistently across every operator and every job cycle, preventing over-pressure events on contractor rigs and rental equipment at 2,700 PSI
• Internal bypass operation — trigger-off bypass smoothly redirects flow through the bypass circuit, preventing deadhead pressure spikes that accelerate seal and valve wear during idle intervals on production wash jobs
• Engine load reduction in bypass — reduced back-pressure lowers engine load in trigger-off mode, reducing fuel consumption and heat accumulation during idle intervals on full-day wash operations
• Brass body construction — resists corrosion from cleaning chemicals, chlorinated water, and sustained outdoor field exposure

F25 SAE J609A — The Standard Contractor Engine Interface at 3/4″ Shaft

Direct Drive. Broad Engine Compatibility. No Adapter Required.

The F25 flange on the XMV3G27D-F25M2 is AR’s SAE J609A direct-drive interface for XM Series ‘D’ version pumps matched to the 3/4″ shaft engine class that dominates the commercial contractor pressure washing market:

• Broad engine compatibility — the F25 SAE J609A 3/4″ shaft standard covers the Honda GX390, Kohler CH395, Briggs and Stratton Vanguard 13, Kawasaki FX481V, and comparable commercial gas engine platforms — the most widely deployed engines on contractor pressure washer frames in the US market
• Diesel engine compatibility — equally compatible with diesel engines equipped with a 3/4″ output shaft and SAE J609A bolt pattern for operations where diesel power is preferred
• Direct close-coupling — the pump mounts face-to-face against the engine with the 3/4″ hollow shaft bore engaging the engine output shaft directly. No belt, jackshaft, or adapter required in a standard direct-drive installation
• Compact installation envelope — direct coupling eliminates belt guards, pulleys, and tensioning hardware, reducing skid and trailer frame dimensions for portable contractor rigs
• Included mounting hardware — bolts and fasteners sized for the F25 SAE J609A bolt pattern are supplied in the box

XM Series Construction for 2,700 PSI Commercial Duty

Solid Ceramic. Forged Brass. Stainless Steel. Built to Be Rebuilt.

The XMV3G27D-F25M2 belongs to AR’s XM Series — a commercial high-pressure platform engineered for the sustained mechanical and thermal demands of 2,700 PSI operation, with every wear component individually serviceable through AR North America’s domestic parts network:

• Solid ceramic plungers — not ceramic-coated, but machined from solid ceramic material throughout. The hardness and dimensional stability of solid ceramic far exceed coated or stainless alternatives at 2,700 PSI operating pressure, maintaining precision plunger geometry across thousands of operating hours and resisting the chemical attack of cleaning solutions that degrade surface coatings. When plungers approach service limits they are replaced individually — 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 and diesel engine operating environments, and sustained chemical exposure without the corrosion pitting and structural degradation that limit cast aluminum manifolds under commercial duty conditions.
• Stainless steel valves maintain precise seating geometry through hundreds of thousands of 2,700 PSI pressure cycles, resisting calcium scale accumulation and surface pitting that cause pressure loss and valve chatter at elevated operating pressures.
• Triplex three-plunger design produces smooth, overlapping pressure pulses that reduce pulsation-induced fatigue stress on hoses, spray guns, and quick-connect fittings — an important advantage at 2,700 PSI where pulsation loads on downstream components are substantially higher than at lower operating pressures.

Why No Injector Is the Right Choice for Some 2,700 PSI Systems

When External Chemical Control Outperforms a Fixed Venturi

The XMV3G27D-F25M2 without an integrated injector is the preferred specification for a well-defined set of professional applications:

• Adjustable-ratio external injectors — operators running downstream injectors with adjustable dilution ratios gain the flexibility to change chemical concentration for different surfaces, contamination levels, and detergent types without modifying the pump or unloader
• Soft wash system integration — soft wash rigs managing chemical delivery through dedicated proportioners or batch tanks keep the pressure pump as a clean water supply source, maintaining precise chemical control independently of the pump platform
• Multiple chemical type applications — contractors applying different chemistry for different surfaces on the same job — degreaser on equipment, roof wash on building exteriors, neutralizer on concrete — benefit from chemical delivery systems that can be swapped and adjusted without touching the pump
• Multi-pump rig configurations — OEM builders and wash system integrators constructing rigs with multiple pump heads or shared chemical infrastructure standardize injection at the system level rather than managing individual venturi injectors at each pump

Typical Applications

Where the XMV3G27D-F25M2 Delivers Best Results

• Professional pressure washing contractors with external chemical systems — 2,700 PSI cleaning output paired with independently managed detergent delivery for concrete restoration, building exterior washing, and commercial property maintenance
• Soft wash operations — the XMV3G27D-F25M2 supplies clean 2,700 PSI rinse water while a dedicated soft wash proportioner manages chemical delivery at correct dilution ratios for each application
• Fleet and heavy vehicle washing — high-pressure output for trucks, trailers, construction equipment, and service vehicles where chemical application is handled through a separate injector system or pre-applied before pressure washing
• Agricultural operations — tractors, combines, barn equipment, and facility washdowns on gas or diesel engine-powered rigs where chemical delivery is managed separately from the pump
• Municipal and government services — utility truck fleets and public works equipment where straight 2,700 PSI output and 3/4″ engine compatibility are the primary requirements
• Rental equipment fleets — tamper-resistant Gymatic pressure control, solid ceramic XM Series construction, and factory-tested reliability maximize rental-ready uptime and minimize service calls
• Contractor rig builders and OEM integrators — F25 3/4″ shaft interface covering the broadest range of standard contractor gas engine platforms, with chemical delivery specified and managed independently at the system level
