SXMV3G40DF24VR3 3.0 GPM 4000 PSI Pump | 3400 RPM F24VR3

SXMV3G40DF24VR3 by Annovi Reverberi — Triplex Plunger Pump with Gymatic VR35 Unloader | 3.0 GPM | 4,000 PSI | 1″ Hollow Keyway Shaft | SAE J609A Gas and Diesel Engine Drive | No Chemical Injector

The SXMV3G40DF24VR3 by Annovi Reverberi is a professional-grade SXMV Series triplex ceramic plunger pump engineered for gas and diesel engine-driven commercial and industrial pressure washing systems operating at 4,000 PSI maximum pressure with dependable Gymatic VR35 bypass control and straight high-pressure water output. Rated at 3.0 GPM and 4,000 PSI at 3,400 RPM, the SXMV3G40DF24VR3 delivers 12,000 cleaning units — matched precisely to its maximum operating pressure by the VR35 unloader’s 4,000 PSI rating — through a 1″ hollow keyway crankshaft and F24 SAE J609A direct-drive flange that close-couples to gasoline or diesel engines with a 1″ cylindrical shaft without adapters or intermediate couplings.

The SXMV3G40DF24VR3 is the clean-water, standard-bypass configuration of the SXMV 3.0 GPM / 4,000 PSI platform — correct for operators managing chemical delivery through a dedicated external downstream injector, soft wash system, or not at all, and for system builders who prefer the F24 face-mount flange installation architecture over the solid-shaft coupling system of the SXMV3G40DVR3IDR variant. No Integrated Dump Regulator. No fixed chemical injector.

Built by Annovi Reverberi in Modena, Italy — with US-based operations, a domestic parts distribution network, and dedicated AR North America technical support — the SXMV3G40DF24VR3 arrives as a complete, factory-tested assembly. Pre-filled with AR break-in oil, equipped with a Gymatic VR35 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 SXMV3G40DF24VR3 is a long-term investment in maximum-pressure commercial pump performance.

Decoding the SXMV3G40DF24VR3 Model Number

What Every Segment of This AR Pump Designation Tells You

The SXMV3G40DF24VR3 encodes pump series, output, shaft type, flange interface, and unloader family directly. Reading each segment before specifying confirms the full configuration of this 4,000 PSI platform:

• S — Series prefix: SXMV high-pressure series — AR’s elevated-duty XM platform variant engineered for 4,000 PSI continuous commercial operation
• XMV — Pump family: XM Series triplex plunger pump with forged brass manifold construction
• 3G40 — Performance rating: 3.0 GPM flow rate at 4,000 PSI maximum operating pressure — 12,000 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 via the F24 SAE J609A face flange
• 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)
• VR3 — Unloader system: Gymatic VR35 — AR’s elevated-capacity Gymatic unloader family rated to 4,000 PSI and 5 GPM, matched precisely to the SXMV3G40DF24VR3’s maximum operating pressure
• No trailing IDR, I, or ID suffix — the model terminates at VR3, confirming standard VR35 bypass operation without an Integrated Dump Regulator and without a downstream chemical injector. This pump delivers straight 4,000 PSI water output.

SXMV 3.0 GPM / 4,000 PSI Platform — Two Variants, Two Installation Architectures

The SXMV 3.0 GPM / 4,000 PSI family includes two configurations that share the same output but differ in installation architecture and bypass management:

• SXMV3G40DF24VR3 (this model) — Gymatic VR35 unloader, standard bypass, no injector, no IDR. F24 SAE J609A face-mount flange with 1″ hollow keyway shaft. Correct for standard direct-drive engine installations using the conventional face-flange coupling architecture. Broader compatibility with standard contractor gas and diesel engine platforms.
• SXMV3G40DVR3IDR — Gymatic VR35 unloader with Integrated Dump Regulator (IDR), no injector. 24 mm solid keyed shaft for keyway hub or flexible coupling drive systems. Correct for specialty drive configurations and highest-cycle production environments where managed bypass pressure dump reduces component stress at 4,000 PSI.

The F24 hollow-shaft face-mount architecture on the SXMV3G40DF24VR3 is the more widely compatible installation option for standard contractor equipment, while the 24 mm solid shaft of the SXMV3G40DVR3IDR serves specialty coupling applications. Confirm your drive system architecture before selecting between these variants.

The Gymatic VR35 at 4,000 PSI — Direct Pressure Match, Stable Bypass

Rated Precisely at Maximum Operating Pressure. Tamper-Resistant. No Injector. No IDR.

The Gymatic VR35 unloader on the SXMV3G40DF24VR3 is rated to 4,000 PSI and 5 GPM — matched to the pump’s maximum operating pressure point. At this pressure level, the VR35’s design headroom and bypass circuit capacity are specifically suited to 4,000 PSI operation:

• Direct pressure-matched regulation — the VR35’s 4,000 PSI rating aligns with the SXMV3G40DF24VR3’s maximum output, providing the most direct, tightly matched pressure regulation in the AR unloader lineup at this duty point
• Adjustable then tamper-resistant — operating pressure set on-site before locking, maintained consistently across every operator, rental cycle, and shift change without re-adjustment or drift on the SXMV3G40DF24VR3
• Standard internal bypass operation — trigger-off bypass on the SXMV3G40DF24VR3 smoothly redirects flow through the VR35 bypass circuit, preventing deadhead pressure spikes that accelerate seal and valve wear during idle intervals on production wash jobs
• No downstream injector port — the SXMV3G40DF24VR3 delivers straight 4,000 PSI water output. Chemical delivery is managed externally — through a dedicated downstream injector, soft wash proportioner, or separate chemical system
• Engine load reduction in bypass — reduced back-pressure in bypass mode lowers engine load and fuel consumption during idle intervals on full-day maximum-pressure wash operations
• Brass body construction — resists corrosion from cleaning chemicals, chlorinated water, and sustained heavy-duty field exposure at 4,000 PSI

Why No Injector and No IDR Is the Right Specification for Some Applications

Clean Water Output at Maximum Pressure. Standard Bypass. F24 Face-Mount Architecture.

The SXMV3G40DF24VR3 without an integrated injector or IDR is the correct specification for a defined set of maximum-pressure professional applications:

• External downstream injector systems — operators running independently adjustable-ratio downstream injectors gain chemical concentration flexibility that a fixed venturi injector built into the unloader cannot provide at 4,000 PSI. External injection systems designed for this pressure range deliver precise ratio control without compromise on the SXMV3G40DF24VR3 platform.
• Soft wash and proportioner systems — soft wash operations managing chemical delivery through dedicated proportioning pumps or batch tanks keep the SXMV3G40DF24VR3 as a clean 4,000 PSI water supply source, maintaining independent chemical control at any dilution ratio
• Standard bypass preference over IDR — operators and system builders who prefer standard VR35 internal bypass operation without the IDR pressure management component, in conjunction with the conventional F24 face-mount installation architecture, specify the SXMV3G40DF24VR3 with confidence
• Standard face-mount engine installations — the F24 SAE J609A hollow shaft face-mount architecture on the SXMV3G40DF24VR3 is compatible with the broadest range of standard 1″ shaft gas and diesel contractor engines, while the SXMV3G40DVR3IDR’s 24mm solid shaft requires keyway hub coupling hardware specific to that configuration
• Multi-pump industrial systems — OEM integrators building systems with multiple SXMV3G40DF24VR3 pump heads or shared chemical infrastructure standardize injection at the system level rather than managing individual pump-integrated injectors

F24 SAE J609A — Direct Drive for Gas and Diesel Engines at 4,000 PSI

Standard Face-Mount. 1″ Hollow Shaft. Broadest Engine Compatibility at Maximum Pressure.

The F24 flange on the SXMV3G40DF24VR3 is AR’s SAE J609A direct-drive interface for XM Series ‘D’ version pumps, providing the most widely compatible installation architecture for the SXMV 4,000 PSI platform:

• Gasoline engine compatibility — direct bolt-up to commercial gas engines with a 1″ cylindrical output shaft and SAE J609A bolt pattern in the high-horsepower class required for 3.0 GPM / 4,000 PSI loads on the SXMV3G40DF24VR3. Verify engine horsepower against the pump duty point before installation.
• Diesel engine compatibility — the F24 SAE J609A standard is equally compatible with standard diesel engines equipped with a 1″ crankshaft, making the SXMV3G40DF24VR3 a natural specification for diesel-powered contractor rigs and industrial equipment at 4,000 PSI
• Direct close-coupling — the SXMV3G40DF24VR3 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
• Broadest standard engine compatibility — the F24 SAE J609A 1″ hollow shaft face-mount is the standard interface across the widest range of commercial 1″ shaft gas and diesel engine platforms in the North American pressure washing market, giving the SXMV3G40DF24VR3 the most straightforward installation path of the SXMV 3.0 GPM / 4,000 PSI variants
• Included mounting hardware — bolts and fasteners sized for the F24 bolt pattern are supplied in the box with the SXMV3G40DF24VR3

SXMV Series Construction — Every SXMV3G40DF24VR3 Component Built for 4,000 PSI

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

• Solid ceramic plungers in the SXMV3G40DF24VR3 resist the substantially elevated seal contact forces and high-velocity water flow at 4,000 PSI. Solid ceramic hardness and dimensional stability are required to maintain precision plunger geometry across the high cycle counts of maximum-pressure commercial operation. Individual replacement when service limits are reached — no full SXMV3G40DF24VR3 pump replacement required.
• Forged brass manifold on the SXMV3G40DF24VR3 provides a dense, pore-free pressure vessel engineered for the cyclic structural stress of 4,000 PSI continuous commercial duty. Forged brass density and pore-free structure are required at this operating point — cast aluminum manifolds are not structurally appropriate for sustained 4,000 PSI operation.
• Stainless steel valves on the SXMV3G40DF24VR3 resist substantially higher seating forces and scale accumulation rates at 4,000 PSI than at lower pressures, maintaining precise seating geometry through hundreds of thousands of maximum-pressure cycles.
• Triplex three-plunger design produces overlapping pressure pulses that reduce pulsation-induced fatigue stress on hoses, spray guns, and fittings connected to the SXMV3G40DF24VR3 throughout the wash system — at 4,000 PSI and 3.0 GPM, the triplex smoothing effect is consequential for downstream equipment life.

Typical Applications

Where the SXMV3G40DF24VR3 Delivers Best Results

• Professional pressure washing contractors with external chemical systems — 4,000 PSI / 3.0 GPM maximum-pressure output from the SXMV3G40DF24VR3 paired with independently managed detergent delivery for concrete restoration, building exterior washing, and surface preparation
• Industrial equipment cleaning — excavators, loaders, construction machinery, and heavy plant equipment where the SXMV3G40DF24VR3’s 4,000 PSI penetrates maximum-contamination surfaces and chemical delivery is managed through an external system
• Fleet and vehicle washing — trucks, buses, trailers, and service vehicles where the SXMV3G40DF24VR3’s maximum pressure handles heavy road film and contamination with chemical applied through a dedicated downstream injector
• Agricultural operations — tractors, combines, and large facility washdowns on gas or diesel engine-powered rigs where the SXMV3G40DF24VR3’s F24 face-mount provides the broadest standard engine compatibility at 4,000 PSI
• Municipal and government services — public works equipment and infrastructure cleaning where the SXMV3G40DF24VR3’s diesel compatibility and maximum output are both operational requirements
• Soft wash system rinse supply — the SXMV3G40DF24VR3 provides clean 4,000 PSI rinse water while a dedicated soft wash proportioner manages chemical delivery independently
• OEM contractors and rig builders — the F24 SAE J609A hollow shaft face-mount on the SXMV3G40DF24VR3 provides the simplest, most widely compatible installation architecture for standard contractor engine platforms at maximum commercial pressure
