XMV35G25DF24C2G by Annovi Reverberi — Triplex Plunger Pump with Gymatic Unloader | 3.5 GPM | 2,500 PSI | 1″ Hollow Keyway Shaft | SAE J609A Gas and Diesel Engine Drive | No Chemical Injector
The XMV35G25DF24C2G by Annovi Reverberi is a commercial-grade XM Series triplex ceramic plunger pump engineered for gas and diesel engine-driven pressure washing systems that prioritize high water volume, efficient commercial cleaning output, and dependable Gymatic bypass pressure control. Rated at 3.5 GPM and 2,500 PSI at 3,400 RPM, the XMV35G25DF24C2G delivers 8,750 cleaning units — the product of flow rate and pressure that defines real-world cleaning productivity — at a duty point that balances strong surface cleaning force with reduced engine horsepower demand compared to 3,000 PSI alternatives at the same flow rate. That combination makes this pump the preferred specification for operators who need the coverage advantage of 3.5 GPM without the engine sizing requirements of the full 3,000 PSI / 3.5 GPM platform.
Built around a 1″ hollow keyway crankshaft and F24 SAE J609A direct-drive flange, the XMV35G25DF24C2G close-couples directly to gasoline or diesel engines with a 1″ cylindrical shaft. The “G” suffix confirms the Gymatic unloader family was installed during AR factory assembly — an internal AR designation that eliminates any ambiguity about unloader specification on the XM Series platform, which can be assembled with either Mini-Matic or Gymatic unloaders depending on the application. No chemical injector is fitted on this model — the pump delivers straight high-pressure water output, correct for systems managing chemical delivery externally.
Built by Annovi Reverberi in Modena, Italy — with US-based operations, a domestic parts distribution network, and dedicated AR North America technical support — the XMV35G25DF24C2G arrives as a complete, factory-tested assembly. Pre-filled with AR break-in oil, equipped with a Gymatic unloader, 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 XMV35G25DF24C2G is a long-term investment in a high-output pump platform capable of a decade of productive commercial service life.
Decoding the XMV35G25DF24C2G 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, assembly confirmation, and injector status — directly into the model number. Reading the XMV35G25DF24C2G correctly before specifying confirms the elevated flow rate, engine compatibility, and full pump configuration:
- XMV — Pump series: XM Series triplex plunger pump — AR’s commercial and industrial high-pressure platform with forged brass manifold construction, engineered for sustained commercial-duty operation
- 35G25 — Performance rating: 3.5 GPM flow rate at 2,500 PSI maximum operating pressure — the elevated flow designation that distinguishes this model from 3.0 GPM XMV variants at the same pressure
- D — Shaft version: Direct Gas/Diesel Drive — 1″ hollow keyway crankshaft bore for direct coupling to gasoline or diesel engine 1″ output shafts
- F24 — Flange type: SAE J609A direct-drive flange for XM/RRV Series ‘D’ version pumps — close coupling to gas or diesel engines with a 1″ I.D. cylindrical shaft (AR part AR41866), compatible with both gasoline engines and standard diesel engines with a 1″ crankshaft and SAE J609A bolt pattern
- C2 — Unloader family: Gymatic (C2 = Gymatic per AR suffix designation) — Gymatic series internal bypass unloader, brass body, adjustable pressure regulation
- G — Assembly confirmation: Gymatic unloader installed. The XM Series platform can be assembled with either a Mini-Matic or Gymatic unloader. The “G” suffix is AR’s internal assembly designation confirming the Gymatic family was specified and installed during manufacturing — eliminating any ambiguity about which unloader is inside this pump.
- No trailing I suffix — the model terminates at C2G with no “I”, confirming this pump delivers straight high-pressure water output without an integrated downstream chemical injector. Operators requiring built-in chemical feed should select the variant with the “I” suffix.
XMV35G25DF24C2G vs XMV35G30D-F24C2 — Choosing Between 2,500 PSI and 3,000 PSI at 3.5 GPM
Both pumps share the same XM Series platform, F24 flange, 1″ keyway shaft, and Gymatic unloader at 3.5 GPM. The pressure rating difference has direct consequences for engine selection and application matching:
- XMV35G25DF24C2G — 3.5 GPM / 2,500 PSI = 8,750 cleaning units: Lower engine horsepower requirement. Correct for applications where 2,500 PSI delivers sufficient cleaning force — fleet vehicles, agricultural equipment, facility surfaces, and general contractor work — and where the available engine is sized for the 2,500 PSI duty point rather than 3,000 PSI. Surface-safer for painted, finished, or softer surfaces where 3,000 PSI risks etching or damage.
- XMV35G30D-F24C2 — 3.5 GPM / 3,000 PSI = 10,500 cleaning units: Higher cleaning productivity on maximum-contamination surfaces — concrete, heavy equipment, and industrial surfaces — but requires a correctly sized engine with sufficient horsepower to sustain 3,000 PSI at 3.5 GPM output.
When the application allows 2,500 PSI and the available engine is sized accordingly, the XMV35G25DF24C2G delivers the 3.5 GPM volume advantage with reduced engine stress and broader engine platform compatibility.

The 3.5 GPM Productivity Advantage at 2,500 PSI
More Water per Hour. Broader Engine Compatibility. Same XM Series Durability.
The XMV35G25DF24C2G’s 3.5 GPM flow rate at 2,500 PSI represents a deliberate performance balance that delivers measurable productivity advantages over standard 3.0 GPM platforms at the same pressure:
- 17% more water volume per hour — at 3.5 GPM vs 3.0 GPM at the same pressure, the higher-flow pump covers proportionally more surface area per hour on large-surface commercial jobs. Parking structures, warehouse exteriors, fleet yards, barn facilities, and agricultural properties where the pump runs for extended periods all benefit directly from the additional flow rate in reduced job time.
- Broader engine compatibility than 3,000 PSI variants — driving a pump at 2,500 PSI requires meaningfully less engine horsepower than at 3,000 PSI at the same 3.5 GPM flow rate. This opens the XMV35G25DF24C2G to a wider range of engine pairings, including engines that are correctly sized for 2,500 PSI output but would be under-rated at 3,000 PSI.
- Surface-safe 2,500 PSI output — on fleet vehicles, agricultural equipment, and commercial surfaces where 3,000 PSI carries surface damage risk, 2,500 PSI delivers strong cleaning force while preserving painted finishes, decals, and treated surfaces that higher pressure would compromise.
- Reduced fuel consumption per square foot cleaned — the lower pressure requirement allows the engine to run at reduced load compared to 3,000 PSI operation, improving fuel efficiency on extended production wash days where the pump operates for hours continuously.
The Gymatic Unloader — Tamper-Resistant Control at 3.5 GPM / 2,500 PSI
Assembly-Confirmed Gymatic. Set It. Lock It. Run All Day.
The Gymatic unloader (C2G) on the XMV35G25DF24C2G is rated above the pump’s 2,500 PSI operating pressure — within AR’s accepted 15% upside variance. At 3.5 GPM, the unloader bypass circuit handles a higher volume of water during trigger-off bypass than on 3.0 GPM variants at the same pressure. The Gymatic’s adjustable-then-lockable design delivers stable regulation across the elevated flow rate:
- Adjustable pressure regulation — operating pressure set on-site before locking, matched to the specific application, nozzle, and surface type
- Tamper-resistant once set — locked pressure held consistently across every operator and every job cycle, preventing over-pressure events at the 3.5 GPM duty point on contractor rigs and rental equipment
- Internal bypass at full 3.5 GPM flow — trigger-off bypass smoothly redirects the complete 3.5 GPM flow through the bypass circuit, preventing deadhead pressure spikes that accelerate seal and valve wear during idle intervals on high-volume production wash jobs
- No downstream injector port — this configuration delivers straight high-pressure water output. Chemical delivery is managed externally through a dedicated downstream injector, soft wash proportioner, or separate chemical application system
- Engine load reduction in bypass — reduced back-pressure in bypass mode lowers engine load and fuel consumption during idle intervals on full-day high-volume wash operations
- Brass body construction — resists corrosion from cleaning chemicals, chlorinated water, and sustained outdoor field exposure
XM Series Construction — Built for 3.5 GPM Commercial Duty
Every Component Scaled to the Elevated Flow Rate
The XMV35G25DF24C2G belongs to AR’s XM Series — a commercial high-pressure platform where every wear component is individually serviceable through AR North America’s domestic parts network:
- Solid ceramic plungers handle the higher water volume and seal contact forces at 3.5 GPM across extended commercial operating hours. Their dimensional stability and hardness maintain precision plunger geometry through thousands of high-volume duty cycles, with individual replacement when service limits are reached — no full pump replacement required.
- Forged brass manifold provides a dense, pore-free pressure vessel that withstands the elevated cyclic flow volume, thermal variance from gas and diesel engine environments, and sustained commercial duty at 3.5 GPM without the micro-porosity and structural degradation that limit cast aluminum manifolds under comparable conditions.
- Stainless steel valves maintain precise seating geometry through the higher cycle frequency of 3.5 GPM operation, resisting calcium scale accumulation and pitting that cause pressure loss and valve chatter in lesser materials.
- Triplex three-plunger design produces smooth, overlapping pressure pulses at 3.5 GPM that reduce pulsation-induced fatigue stress on hoses, spray guns, surface cleaners, and downstream fittings throughout the wash system.
F24 SAE J609A — Direct Drive for Gas and Diesel Engines
One Flange Standard. Gasoline or Diesel. No Adapter Required.
- Gasoline engine compatibility — direct bolt-up to commercial gas engines with a 1″ cylindrical output shaft and SAE J609A bolt pattern in the horsepower class appropriate for 3.5 GPM / 2,500 PSI loads
- Diesel engine compatibility — the F24 SAE J609A standard is equally compatible with standard diesel engines equipped with a 1″ crankshaft, making the XMV35G25DF24C2G a natural specification for diesel-powered contractor rigs, agricultural equipment, and municipal service vehicles where diesel is the operational fuel standard
- Direct close-coupling — the pump mounts face-to-face against the engine with the 1″ hollow keyway crankshaft bore engaging the engine shaft directly, eliminating belt guards, pulleys, and tensioning hardware
- Compact installation envelope — direct coupling reduces skid and trailer frame dimensions for portable contractor rigs and trailer-mounted wash systems
- Included mounting hardware — bolts and fasteners sized for the F24 SAE J609A bolt pattern are supplied in the box
Typical Applications
Where the XMV35G25DF24C2G Delivers Best Results
- Large-surface commercial pressure washing — warehouse exteriors, parking structures, loading docks, and large concrete surfaces where 3.5 GPM covers more square footage per hour than 3.0 GPM alternatives at the same pressure
- Fleet and vehicle washing operations — truck terminals, bus depots, and fleet yards where 2,500 PSI effectively removes road film and general contamination from painted vehicles without surface damage risk, at high volume for fast cycle times
- Agricultural operations — tractors, combines, barn equipment, and facility washdowns on gas or diesel engine-powered rigs where 2,500 PSI handles organic contamination effectively without damaging equipment decals, plastic components, or treated surfaces
- Construction and equipment cleaning — machinery and equipment washdowns where 3.5 GPM flow rate accelerates rinsing time on large surface areas after degreaser pre-treatment
- Municipal and government services — utility truck fleets, public works equipment, and infrastructure cleaning rigs where diesel compatibility and high-volume output are both operational requirements
- Contractor rigs with engine-sizing constraints — operations where the available engine is correctly sized for 2,500 PSI at 3.5 GPM but not rated for the additional horsepower demand of 3,000 PSI at the same flow rate
- Rental equipment fleets — Gymatic-confirmed tamper-resistant pressure control, 3.5 GPM surface coverage, and XM Series durability support high-utilization commercial rental cycles
