The RRV4G40HD-F24C2I by Annovi Reverberi is a heavy-duty RR Series triplex ceramic plunger pump engineered for gas and diesel engine-driven commercial and industrial pressure washing systems operating at 4,000 PSI with integrated downstream chemical application capability. Rated at 4.0 GPM and 4,000 PSI at 3,400 RPM, the RRV4G40HD-F24C2I delivers 16,000 cleaning units — the maximum output in the AR commercial pump lineup — through a reinforced heavy-duty crankcase with bronze connecting rods, solid ceramic plungers, a forged brass manifold, and an F24 SAE J609A direct-drive flange for close-coupling to gasoline or diesel engines.

The RRV4G40HD-F24C2I belongs to AR’s RR Series — a distinct pump platform from the XMV and SXMV Series, engineered for maximum-pressure heavy-duty commercial applications where reinforced crankcase construction, bronze connecting rods, and the HD (Heavy Duty) build specification are the correct engineering choice for sustained 4,000 PSI continuous-duty operation. The “HD” designation within the model number confirms this elevated internal construction standard, distinguishing the RRV4G40HD-F24C2I from standard RRV Series variants.

Built by Annovi Reverberi in Modena, Italy — with US-based operations, a domestic parts distribution network, and dedicated AR North America technical support — the RRV4G40HD-F24C2I arrives as a complete, factory-tested assembly. Pre-filled with AR break-in oil, equipped with a Gymatic unloader and active downstream chemical injector, and packaged with 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 RRV4G40HD-F24C2I is a long-term investment in maximum-output commercial pump performance.

Decoding the RRV4G40HD-F24C2I Model Number

What Every Segment of This AR Pump Designation Tells You

The RRV4G40HD-F24C2I encodes pump series, output, duty specification, flange interface, unloader family, and injector configuration directly. Reading each segment before specifying confirms the pump’s platform, heavy-duty build level, engine compatibility, and chemical feed configuration:

• RRV — Pump series: RR Series triplex plunger pump — a distinct AR pump platform from the XMV and SXMV Series, engineered for heavy commercial and industrial applications
• 4G40 — Performance rating: 4.0 GPM flow rate at 4,000 PSI maximum operating pressure — 16,000 cleaning units
• HD — Heavy Duty specification: elevated internal construction standard with reinforced crankcase and bronze connecting rods, distinguishing this variant from standard RRV Series configurations at the same output rating
• F24 — Flange type: SAE J609A direct-drive flange for RR Series ‘D’ version pumps — close coupling to gas or diesel engines with a 1″ I.D. cylindrical shaft (AR part AR41866)
• C2 — Unloader code: Gymatic (C2 = Gymatic per AR suffix designation) — Gymatic series internal bypass unloader, brass body, adjustable pressure regulation, factory-fitted with downstream chemical injector
• 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

RRV Series vs XMV/SXMV Series — Understanding the Platform Difference

The RRV4G40HD-F24C2I belongs to AR’s RR Series — a pump platform distinct from the XMV and SXMV Series described throughout this product line. While both platforms deliver commercial-grade triplex plunger performance, the RR Series carries its own engineering lineage within AR’s product family:

• RR Series (RRV) — AR’s dedicated heavy commercial and industrial triplex pump platform, designed around a specific crankcase and manifold architecture optimized for high-pressure continuous-duty applications. The HD variant specification adds reinforced crankcase construction and bronze connecting rods to the standard RRV platform.
• XMV/SXMV Series — AR’s XM Series commercial high-pressure pump family, sharing the F24/F40 flange compatibility and similar operating ranges but built on a different crankcase and manifold architecture from the RR Series.

When specifying replacement pumps, service parts, or comparing configurations, confirm that RRV Series part numbers and specifications are used for the RRV4G40HD-F24C2I rather than XMV Series references.

HD Heavy Duty Construction — Reinforced Crankcase and Bronze Connecting Rods

Why the HD Specification Matters at 4,000 PSI / 4.0 GPM

The RRV4G40HD-F24C2I‘s Heavy Duty specification encompasses two internal construction upgrades specifically relevant to 4,000 PSI / 4.0 GPM continuous commercial operation — the most demanding duty point in the AR commercial pump lineup:

Reinforced Crankcase

The reinforced crankcase in the RRV4G40HD-F24C2I provides structural margin beyond the standard RRV Series crankcase for maximum-output applications:

• Higher cyclic load capacity — at 4.0 GPM and 4,000 PSI, the crankcase absorbs the combined mechanical forces of maximum flow volume and maximum pressure on every reciprocation cycle. The reinforced architecture distributes these loads across a more robust structure, reducing fatigue-induced cracking and deformation over extended service life.
• Reduced vibration transmission — a more rigid crankcase structure at maximum operating load reduces vibration transmission to the engine mounting and downstream system components, extending the service life of hoses, fittings, and mounting hardware throughout the wash system.
• Extended service intervals — reinforced crankcase construction reduces the frequency of crankcase-related service events in production environments running the RRV4G40HD-F24C2I at or near maximum output for extended daily periods.

Bronze Connecting Rods

The bronze connecting rods in the RRV4G40HD-F24C2I provide premium internal crankcase performance at the highest commercial duty point:

• Superior fatigue strength at maximum pressure — bronze alloys resist the repeated load cycling of 4,000 PSI / 4.0 GPM operation more effectively than aluminum, extending connecting rod service life in the most demanding daily duty cycles
• Higher wear resistance at bearing interfaces — bronze’s tribological properties reduce wear at connecting rod bearing surfaces under the elevated load conditions of maximum-output continuous operation
• Thermal stability — bronze maintains dimensional stability across the temperature range of maximum-pressure continuous-duty operation, reducing thermal distortion at bearing surfaces during extended production wash sessions

Integrated Chemical Injection at 4,000 PSI — Two-Mode Maximum-Pressure Platform

Pre-Soak, Degrease, and 4,000 PSI Rinse Through the RRV4G40HD-F24C2I

The integrated downstream chemical injector on the RRV4G40HD-F24C2I delivers full two-mode capability at maximum operating pressure:

• Venturi-driven downstream injection — the injector integrated into the Gymatic unloader body draws detergent, degreaser, or pre-soak solution from a supply container when the RRV4G40HD-F24C2I operator switches to low-pressure application mode. No chemical pump or powered dosing system required.
• Two-mode workflow at 4.0 GPM / 4,000 PSI — chemical pre-soak breaks down maximum-contamination grease, oil, and embedded grime on industrial equipment, fleet vehicles, and large commercial surfaces; full 4,000 PSI / 4.0 GPM rinse removes loosened material at 16,000 cleaning units of output — the highest rinse productivity in the AR commercial lineup.
• No separate injector hardware required on the RRV4G40HD-F24C2I — the complete two-mode system is factory-assembled. One assembly. Two operating modes.
• Injector maintenance — flush the RRV4G40HD-F24C2I injector circuit with clean water after every detergent session to prevent chemical residue buildup in the venturi passage, preserving long-term function as detailed in the included operator’s manual.

F24 SAE J609A — Direct Drive for Gas and Diesel Engines at Maximum Output

One Standard. Gasoline or Diesel. Engine Sizing Critical at 4.0 GPM / 4,000 PSI.

• 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 4.0 GPM / 4,000 PSI loads on the RRV4G40HD-F24C2I. Verify engine horsepower against the pump’s 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 RRV4G40HD-F24C2I a natural specification for diesel-powered heavy contractor rigs and industrial equipment at maximum pressure
• Direct close-coupling — the RRV4G40HD-F24C2I 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 at maximum output
• Included mounting hardware — bolts and fasteners sized for the F24 SAE J609A bolt pattern are supplied in the box with the RRV4G40HD-F24C2I
