RKV4G37D-F24 Triplex Plunger Pump | 4.0 GPM 3700 PSI

RKV4G37D-F24 Triplex Pump

The Annovi Reverberi RKV4G37D-F24 is a high-performance triplex plunger pump designed for commercial and
industrial cleaning systems that run hard and demand consistent output. Rated 4.0 GPM at 3700 PSI and operating
at 3400 RPM, it provides the pressure, flow, and duty cycle needed for contractor rigs, fleet wash bays, and
facility maintenance equipment. With an F24 direct-mount flange and 1″ hollow keyed shaft, this pump is
built to pair cleanly with gasoline or diesel engines in compact, efficient direct-drive packages.

• Engineered for continuous or frequent-duty use in demanding environments.
• Suitable for hot- or cold-water commercial pressure washer systems.
• Built around industrial-grade materials for long service life and predictable performance.

Performance & Operating Envelope

• Flow: 4.0 gallons per minute, sized for aggressive cleaning with effective rinse capacity.
• Pressure: 3700 PSI maximum for heavy soil removal on steel, concrete, and equipment.
• Speed: 3400 RPM for compact engine-driven systems with high cleaning throughput.
• Pump Type: Triplex ceramic plunger pump for smooth, low-pulsation output.
• Duty Class: Commercial and industrial applications with regular or continuous operation.

Mounting, Drive & System Integration

• F24 flange mount designed for direct coupling to 1″ gasoline or diesel engine shafts.
• 1″ hollow keyway shaft accepts standard keyed engine outputs for secure torque transfer.
• Direct-drive configuration removes the need for belts and pulleys, reducing mechanical losses and adjustments.
• Compact layout simplifies installation on trailers, skids, and OEM frames where space is limited.
• Direct coupling improves alignment, reducing vibration and extending bearing and seal life.

Internal Construction & Materials

• Heavy-duty brass manifold provides corrosion resistance in wash bays and outdoor environments.
• Solid ceramic plungers resist wear and thermal shock, protecting packings under high duty cycles.
• Bronze connecting rods deliver high strength and fatigue resistance under continuous load.
• Oversized crankshaft bearings stabilize the rotating assembly for smoother operation.
• Stainless-steel inlet and discharge valves ensure reliable sealing and fast response at high cycling rates.
• Reinforced crankcase is designed to manage heat, vibration, and mechanical stress over thousands of hours.

How the RKV4G37D-F24 Operates

• Three ceramic plungers are driven by a precision-machined crankshaft to generate a continuous high-pressure
  water stream with reduced pulsation compared to axial pumps.
• Bronze connecting rods distribute loading evenly along the crankshaft, limiting localized stress and extending
  the service life of internal components.
• Stainless valves open and close in rapid sequence to maintain steady flow and pressure during demanding
  cleaning cycles.
• The F24 flange and hollow shaft provide a rigid, aligned connection to the engine, helping convert engine power
  directly into hydraulic energy with minimal loss.
• The pump is designed to hold pressure under repeated trigger cycling in real-world wash bay and mobile rig use.

Supplied Configuration & Startup Details

• Delivered factory-assembled and performance-tested to confirm flow and pressure targets.
• Pre-filled break-in oil in the crankcase reduces wear during initial operation.
• Oil sight glass allows quick visual verification of oil level and condition before each shift.
• Vented dipstick simplifies oil checks and supports proper crankcase ventilation.
• Operator’s manual and illustrated schematic support installation, troubleshooting, and future rebuilds.
• Secure packaging protects the pump during handling, storage, and transport to the installation site.

Operational Benefits RKV4G37D-F24 for Professional Users

• High cleaning energy: 3700 PSI at 4.0 GPM tackles baked-on grime, road film, and heavy residues.
• Consistent output: Triplex architecture provides a stable spray pattern for uniform surface coverage.
• Compact, efficient design: Direct-drive F24 layout keeps systems lighter and easier to service.
• Low routine maintenance: External oil monitoring points simplify daily checks and scheduled service.
• Long-term value: Industrial materials and robust driveline support multi-year service in harsh duty.
• Warranty support: Covered by a limited 5-year warranty backed by AR service channels.

Typical Applications

• Commercial cleaning rigs: Trailer and skid systems used for storefronts, sidewalks, and pads.
• Industrial maintenance: Washdown of conveyors, production areas, and plant equipment.
• Fleet and vehicle washing: High-pressure bays for trucks, buses, delivery vans, and service fleets.
• Construction equipment: Cleaning excavators, loaders, mixers, and rental machinery between jobs.
• Agricultural operations: Washing tractors, implements, and livestock areas in high-use facilities.
• Municipal and contractor work: Mobile wash crews handling parking decks, facilities, and public works assets.

Why Specify the RKV4G37D-F24

• Provides a proven balance of flow, pressure, and speed for most 4 GPM / high-PSI contractor and fleet applications,
  reducing guesswork in system design.
• Triplex plunger design and industrial-grade internals offer a clear upgrade over consumer and light-commercial
  axial pumps.
• Direct-drive F24 interface streamlines engine integration, making it suitable for new builds, retrofits, and
  OEM production platforms.
• With documented performance, accessible service points, and a long warranty window, the RKV4G37D-F24 is a
  practical choice for operators who treat uptime and lifecycle cost as critical metrics.
