RRV4G40HD-F24 Triplex Plunger Pump | 4.0 GPM 4000 PSI

RRV4G40HD-F24 Triplex Plunger Pump

The Annovi Reverberi RRV4G40HD-F24 is a heavy-duty
triplex plunger pump engineered for high-performance
commercial and industrial pressure washing. Delivering
4.0 GPM at up to 4,000 PSI and operating at a fast
3,400 RPM, this F24-flange pump is an excellent choice for
direct-drive gas engine units, mobile wash skids, fleet-wash trailers, and
contractor-grade cold-water systems that run hard, day after day.

Built on AR’s proven RRV platform, the RRV4G40HD-F24 combines a
forged brass manifold, solid ceramic plungers,
and a rugged aluminum crankcase with cooling fins to withstand
sustained duty cycles. The HD designation indicates an
upgraded heavy-duty configuration, ideal for professional users who demand
longer life, stronger components, and reliable uptime in tough environments.

Pump Architecture & Construction

RRV4G40HD-F24 Triplex Plunger Design

• Three-plunger reciprocating design delivers smoother flow and reduced pulsation versus axial-cam pumps, improving wand control and nozzle pattern stability.
• Ceramic plungers offer outstanding abrasion resistance and lower friction, extending seal and packing life under high pressure.
• Forged brass manifold head resists corrosion and pressure fatigue, providing long-term durability with standard wash water and detergents.
• Oversized crankshaft and bearings support continuous operation at 3,400 RPM, ideal for contractor and fleet cleaning duty cycles.
• Heavy-duty seal and valve design supports long service intervals when paired with proper filtration and maintenance.

F24 Engine Flange & Drive End

• F24 gas engine flange allows direct mounting to compatible small gasoline engines, simplifying assembly and alignment.
• 1″ hollow shaft (typical for this configuration) slides onto the engine output shaft for compact, rigid coupling.
• Direct-drive configuration minimizes power loss, reduces belt-related maintenance, and keeps the overall package footprint small.
• Ideal for 4,000 PSI contractor machines in the 11–15 HP engine class, depending on duty and accessories.

Applications & Industry Use Cases

Professional Pressure Washing

• Contractor-grade pressure washers for residential and commercial exterior cleaning.
• Fleet wash operations servicing trucks, buses, trailers, and heavy equipment.
• Construction cleanup for concrete forms, equipment, and job-site washdown.
• Property maintenance crews handling sidewalks, building exteriors, parking lots, and loading docks.

Industrial & Facility Cleaning

• Manufacturing and industrial plants requiring robust 4,000 PSI cleaning for floors, machinery, and staging areas.
• Waste and recycling facilities dealing with heavy soils, grease, and residue on pads and equipment.
• Municipal and public works departments maintaining public spaces, utility equipment, and infrastructure.
• Rental fleets of commercial cold-water pressure washers where durability and easy service are key.

Installation & System Integration

Engine Pairing & Mounting

• Designed for direct-drive gasoline engines with 1″ shafts using the F24 bolt pattern.
• Match engine power to the pump’s duty point—4.0 GPM at 4,000 PSI generally requires around 11–13 HP depending on efficiency.
• Mount pump and engine on a rigid, aligned baseplate to minimize vibration and shaft stress.
• Provide adequate airflow around the crankcase to help dissipate heat during extended run times.

Plumbing & System Design

• Use proper inlet plumbing with adequately sized hose and fittings to maintain positive inlet pressure—avoid suction lift where possible.
• Install a 50–100 micron inlet filter/strainer to protect valves, seals, and plungers from debris.
• Pair the pump with a properly sized unloader valve, safety relief, and pressure gauge rated for at least 4,000 PSI.
• Match high-pressure nozzle size to 4.0 GPM @ 4,000 PSI to keep engine load and system pressure within design parameters.

Maintenance & Serviceability

Service-Friendly Features

• External oil fill, sight glass, and drain plug make routine oil checks and changes quick for shop techs and contractors.
• Removable valve caps allow fast inspection and replacement of check valves when performance drops.
• Ceramic plungers and premium seal packs extend service intervals and can be renewed using standard AR repair kits.
• Regularly monitor oil condition, inlet filtration, and unloader settings to maximize pump life.
• Includes bolts and locking washers, factory break-in oil, vented dipstick, and operator manual.
• When installed correctly and maintained on schedule, the RRV4G40HD-F24 delivers
  years of reliable, heavy-duty service in demanding pressure washing applications.
