SXMV3G35DF24C1I 3.0 GPM 3500 PSI Pump | 3400 RPM F24C1I

SXMV3G35DF24C1I by Annovi Reverberi — Triplex Plunger Pump with Gymatic VR35 Unloader and Chemical Injector | 3.0 GPM | 3,500 PSI | 1″ Hollow Keyway Shaft | SAE J609A Gas and Diesel Engine Drive

The SXMV3G35DF24C1I by Annovi Reverberi is a commercial-grade SXMV Series triplex ceramic plunger pump engineered for gas and diesel engine-driven pressure washing systems operating at 3,500 PSI — a high-performance pressure point demanding the elevated bypass capacity of the Gymatic VR35 unloader — with integrated downstream chemical application capability for the complete two-mode professional wash platform. Rated at 3.0 GPM and 3,500 PSI at 3,400 RPM, the SXMV3G35DF24C1I delivers 10,500 cleaning units — matching the cleaning productivity of the highest-output 3.5 GPM / 3,000 PSI platform — through a 1″ hollow keyway crankshaft and F24 SAE J609A direct-drive flange that close-couples directly to gasoline or diesel engines without adapters or intermediate couplings.

The SXMV3G35DF24C1I carries the C1 unloader designation — confirming the Gymatic VR35, AR’s elevated-capacity Gymatic variant rated to 4,000 PSI and 5 GPM. At 3,500 PSI, the VR35 operates with 500 PSI of headroom above the pump’s maximum output — providing a stable regulation window and extended unloader service life that the standard Gymatic 3/B, rated to 3,650 PSI, cannot deliver with the same margin at this pressure point. The integrated downstream chemical injector completes the SXMV3G35DF24C1I as a self-contained two-mode wash assembly.

Built by Annovi Reverberi in Modena, Italy — with US-based operations, a domestic parts distribution network, and dedicated AR North America technical support — the SXMV3G35DF24C1I arrives as a complete, factory-tested assembly. Pre-filled with AR break-in oil, equipped with a Gymatic VR35 unloader and active downstream chemical injector, 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 SXMV3G35DF24C1I is a long-term investment in a high-pressure commercial pump platform capable of a decade of productive service life.

Decoding the SXMV3G35DF24C1I 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 variant, and injector configuration — directly into the model number. Reading the SXMV3G35DF24C1I correctly before specifying confirms the pressure rating, unloader family, engine compatibility, and chemical feed configuration:

• S — Series prefix: SXMV high-pressure series — AR’s elevated-duty XM platform variant used for pumps operating at the upper end of the commercial pressure range
• XMV — Pump family: XM Series triplex plunger pump with forged brass manifold construction
• 3G35 — Performance rating: 3.0 GPM flow rate at 3,500 PSI maximum operating pressure — 10,500 cleaning units
• 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
• C1 — Unloader variant: Gymatic VR35 — AR’s elevated-capacity Gymatic unloader family, rated to 4,000 PSI and 5 GPM. At 3,500 PSI the VR35 provides 500 PSI of operating headroom — a tighter but still appropriate margin that delivers more stable bypass regulation than a 3,650 PSI-rated Gymatic 3/B would provide at this operating pressure.
• I — Chemical injector: Included — a downstream soap and chemical injector is integrated into the Gymatic VR35 unloader assembly, enabling low-pressure detergent application without a separate injector fitting

Why 3,500 PSI Requires the VR35 — C1 vs C2 at This Pressure Point

The pressure difference between 3,000 PSI and 3,500 PSI is small in absolute terms but consequential for unloader specification. Understanding why the SXMV3G35DF24C1I carries the C1/VR35 rather than the C2/Gymatic 3/B:

• C1 — Gymatic VR35 (this model): Rated to 4,000 PSI and 5 GPM. Provides 500 PSI of headroom above 3,500 PSI — within AR’s 15% upside variance and appropriate for this operating point. The VR35’s elevated bypass circuit capacity delivers stable regulation at 3,500 PSI with meaningful service life advantage over the standard 3/B at this pressure. Unloader part reference: AR22287 (adjustable, 2.0 injector ratio, 4,000 PSI, 5 GPM, 1/2″ M inlet, 3/8″ M outlet, brass body).
• C2 — Gymatic 3/B: Rated to 3,650 PSI. Provides only 150 PSI of headroom above 3,500 PSI — within the 15% variance technically, but at the narrow end of the acceptable range. Operating a Gymatic 3/B near its rated ceiling at 3,500 PSI produces higher internal stress on bypass components and shorter rebuild intervals compared to the VR35 at the same pressure. The C1/VR35 is the correct specification for the SXMV3G35DF24C1I’s 3,500 PSI duty point.

The Gymatic VR35 Unloader at 3,500 PSI — Why Headroom Matters

500 PSI Above Operating Pressure. Set It. Lock It. Maximum Regulation Stability.

The Gymatic VR35 unloader (AR22287) on the SXMV3G35DF24C1I is rated to 4,000 PSI — providing 500 PSI of operating headroom above the pump’s 3,500 PSI output. At this pressure point, that margin is operationally significant:

• Stable regulation window at 3,500 PSI — the 500 PSI gap between operating pressure and rated ceiling produces a consistent, responsive bypass regulation behavior. The SXMV3G35DF24C1I’s VR35 operates confidently within its design envelope rather than near its rated limit, maintaining stable pressure output during continuous production wash cycles.
• Extended unloader service life — bypass valve components, springs, and seating surfaces in the VR35 operating at 3,500 PSI against a 4,000 PSI-rated circuit experience less cumulative stress than a Gymatic 3/B operating with only 150 PSI of headroom at the same pressure, extending the rebuild interval on the SXMV3G35DF24C1I in high-cycle commercial environments.
• Tamper-resistant once set — locked pressure held consistently across every operator and every job cycle, preventing over-pressure events on contractor rigs and rental equipment at 3,500 PSI
• Internal bypass operation — trigger-off bypass on the SXMV3G35DF24C1I smoothly redirects flow, preventing deadhead pressure spikes that accelerate seal and valve wear during idle intervals
• Integrated downstream chemical injector — the venturi injector in the VR35 draws detergent, degreaser, or pre-soak solution from a supply container when the SXMV3G35DF24C1I operator switches to low-pressure application mode. No separate injector hardware required.
• Engine load reduction in bypass — reduced back-pressure lowers engine load and fuel consumption during idle intervals on full-day wash operations
• Brass body construction — resists corrosion from cleaning chemicals, chlorinated water, and sustained outdoor field exposure

Integrated Chemical Injection — Two-Mode Wash at 3,500 PSI

Pre-Soak, Degrease, and 3,500 PSI Rinse Through the SXMV3G35DF24C1I

The integrated downstream chemical injector on the SXMV3G35DF24C1I delivers full two-mode capability — high-pressure rinse and low-pressure detergent pre-soak — without additional hardware:

• Venturi-driven downstream injection — the VR35-integrated injector draws detergent, degreaser, or pre-soak solution from a supply container when the SXMV3G35DF24C1I operator switches to low-pressure application mode. No chemical pump or powered dosing system required.
• Two-mode workflow at 3,500 PSI — chemical pre-soak breaks down contamination on fleet vehicles, construction equipment, and commercial surfaces; full 3,500 PSI / 3.0 GPM rinse removes loosened material efficiently. At 10,500 cleaning units, the SXMV3G35DF24C1I’s rinse phase clears treated surfaces faster than any 3.0 GPM / 3,000 PSI platform in the AR lineup.
• No separate injector hardware required on the SXMV3G35DF24C1I — the complete two-mode system is factory-assembled. One assembly. Two operating modes.
• Injector maintenance — flush the SXMV3G35DF24C1I injector circuit with clean water after every detergent session to prevent chemical residue buildup in the VR35 venturi passage, preserving long-term injector function as detailed in the included operator’s manual.

F24 SAE J609A — Direct Drive for Gas and Diesel Engines at 3,500 PSI

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 3.0 GPM / 3,500 PSI loads on the SXMV3G35DF24C1I
• Diesel engine compatibility — the F24 SAE J609A standard is equally compatible with standard diesel engines equipped with a 1″ crankshaft, making the SXMV3G35DF24C1I a natural specification for diesel-powered contractor rigs, agricultural equipment, and municipal service vehicles
• Direct close-coupling — the SXMV3G35DF24C1I 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
• Included mounting hardware — bolts and fasteners sized for the F24 SAE J609A bolt pattern are supplied in the box with the SXMV3G35DF24C1I

SXMV Series Construction — Every SXMV3G35DF24C1I Component Built for 3,500 PSI

Solid Ceramic. Forged Brass. Stainless Steel. Individually Rebuildable.

• Solid ceramic plungers in the SXMV3G35DF24C1I resist the elevated seal contact forces and higher-velocity water flow at 3,500 PSI. Their hardness and dimensional stability maintain precision plunger geometry across thousands of high-pressure operating hours. Individual replacement when service limits are reached — all other SXMV3G35DF24C1I components remain in productive service.
• Forged brass manifold on the SXMV3G35DF24C1I provides a dense, pore-free pressure vessel that withstands the cyclic mechanical stress, thermal variance from gas and diesel engine environments, and chemical exposure from the downstream injector at 3,500 PSI without the structural degradation that limits cast aluminum manifolds under comparable conditions.
• Stainless steel valves on the SXMV3G35DF24C1I maintain precise seating geometry through hundreds of thousands of 3,500 PSI pressure cycles, resisting calcium scale accumulation and pitting that cause pressure loss at elevated operating pressures.
• Triplex three-plunger design produces smooth, overlapping pressure pulses that reduce pulsation-induced fatigue stress on hoses, spray guns, and fittings connected to the SXMV3G35DF24C1I throughout the wash system.
