RRV3G34D-F24 Pressure Washer Pump | 3.0 GPM 3600 PSI

Overview

The Annovi Reverberi RRV3G34D-F24 is a high-pressure,
industrial-duty triplex plunger pump built for direct drive on gasoline
engines. Rated up to 3.0 GPM at 3,400 PSI and engineered
for 3,400 RPM operation, this RRV-series pump delivers
serious cleaning power in a compact, 1″ hollow-shaft package. With a
brass manifold, solid ceramic plungers, and frictionless aluminum connecting
rods, the RRV3G34D-F24 is an excellent heart for commercial cold- or hot-water
pressure washer skids, trailer rigs, and contractor machines that run all day.

• Direct-drive triplex plunger pump for gas engines with F24 mounting flange.
• Delivers approximately 3.0 GPM at up to 3,400 PSI for tough cleaning jobs.
• 3400 RPM operating speed matched to common 3–7 HP horizontal engines.
• D-version 1″ hollow shaft for easy engine coupling with key and bolt.
• Compact ~18 lb frame for tight skid layouts and portable units.

High-Pressure Performance

The RRV3G34D-F24 is designed for applications where you need concentrated
impact, not massive flow. At 3 GPM and up to 3,400 PSI, it creates a tight,
aggressive jet that cuts through baked-on road film, grease, oxidation, and
compacted dirt. This makes it ideal for one-gun contractor machines,
mobile rigs, and wash bays that demand fast cleaning with reasonable water
usage.

• Max flow: 3.0 GPM – ideal for single-gun systems with 3/8″ hose.
• Max pressure: up to 3,400 PSI for heavy-duty cleaning and prep work.
• Max speed: 3,400 RPM matched to direct-drive gas engines.
• Max fluid temperature: 140°F (60°C) – compatible with most hot-water skids using inlet tempering.

Triplex plunger architecture

As a three-piston volumetric pump, the RRV3G34D-F24 produces smoother flow
than axial or twin-plunger designs. This reduces pressure ripple and hose
“kick,” improving operator control and extending the life of guns, lances,
hoses, and rotating nozzles.

• Three ceramic plungers phased 120° apart for more continuous flow.
• Reduced pulsation at the gun for a steadier spray pattern.
• Less vibration transmitted into the frame and engine base.
• Better compatibility with turbo nozzles, surface cleaners, and hose reels.

Construction and Materials

The RRV3G34D-F24 uses a proven combination of a brass manifold head and a
die-cast aluminum crankcase. Inside, ceramic plungers, stainless steel
valves, and aluminum connecting rods work together to withstand continuous
duty in demanding wash environments.

• Manifold head: forged brass for strength and corrosion resistance.
• Crankcase: finned aluminum housing to shed heat at 3,400 RPM.
• Plungers: 15 mm solid ceramic plungers to minimize scoring and extend seal life.
• Valves: stainless steel valve assemblies for consistent sealing under high pressure.
• Connecting rods: frictionless aluminum rods designed for high-speed direct-drive duty.

Wet-end durability

The wet end is engineered for real-world contractor abuse – frequent trigger
cycling, varying inlet conditions, and long hose runs. Quality seals, O-rings,
and valve components keep the pump performing reliably between service
intervals.

• High-pressure packings and low-pressure seals protect the crankcase from water intrusion.
• Inlet ports: typically dual 1/2″ F ports for flexible plumbing.
• Outlet port: 3/8″ F discharge for standard pressure washer hose connections.
• Oil capacity around 13.35 oz for robust lubrication (check data plate/manual for exact spec).

F24 Gas Engine Flange and Drive

The “D-F24” designation means this pump is built for direct mounting to gas
engines with the appropriate F24 flange pattern and 1″ horizontal shaft
layout. The 1″ hollow D-shaft slides onto the engine crankshaft and is
secured with a key and bolt, creating a compact, efficient package with no
belts to maintain.

• 1″ hollow D-shaft designed for horizontal gas engine crankshafts.
• F24 flange pattern for common small-frame gasoline engines.
• Direct drive minimizes power loss and eliminates belt alignment issues.
• Compact bolt-on design ideal for OEM assemblies and replacement upgrades.

Serviceability

Like other RRV-series pumps, the RRV3G34D-F24 is designed for straightforward
maintenance. Wear components are available in standardized kits, and the head
and valve layout is built for fast access with basic shop tools.

• Standard valve kits, water seal kits, and oil seal kits widely available.
• Side oil sight glass and drain plug for quick oil checks and changes.
• Removable valve caps for easy inspection and replacement of valve assemblies.
• Head removal is simple for packing and plunger service.

Typical Applications

With its 3 GPM / 3,400 PSI performance and direct-drive gas engine interface,
the RRV3G34D-F24 is suited to a wide range of professional cleaning and
maintenance tasks.

• Contractor pressure washers – mobile rigs for building exteriors, sidewalks, and decks.
• Fleet and equipment wash – trucks, trailers, forklifts, construction machinery.
• Rental yard units – robust yet compact pumps for rental pressure washers.
• Hot- or cold-water skid builds – integrates easily into burner-equipped trailer systems.
• General industrial cleaning – plant maintenance, yard cleanup, and prep work.
