How the RMW22G24-EZ-F7 Works

The RMW22G24-EZ-F7 employs a proven axial cam mechanism that converts engine rotation into linear plunger motion, producing a steady high-pressure water stream with minimal internal friction. The triplex-style motion (three plungers working in sequence) reduces pulsation and vibration, giving smoother spray patterns and improved operator comfort. The EZ Start system is a key convenience feature: it prevents full hydraulic lock (static back pressure) while the engine is started with the spray gun closed, dramatically lowering the pull force required to start small gasoline engines and reducing starter strain and wear.

The integrated unloader provides a safe bypass path when the gun is closed, allowing the operator to set working pressure without resorting to external bypass hardware. When detergent cleaning is needed, the built-in chemical injector draws soap into the water stream, improving cleaning efficiency for grease, oil, and heavy soils. The maintenance-free crankcase arrives filled with synthetic oil at the factory, eliminating routine crankcase service and greatly simplifying ownership for casual and occasional users.

Durability & Construction

• Ceramic plungers for excellent resistance to wear, heat, and abrasive particles
• Stainless-steel valves for corrosion resistance and long service life
• Premium seals and O-rings selected for longevity in detergent-rich environments
• Robust axial cam design for compact size and efficient power transfer
• Quality control: factory-testing ensures each unit meets flow, pressure, and sealing specifications

Benefits You’ll Notice

• Easier Starts: EZ Start reduces static back pressure so engines pull easier and start more reliably.
• Low Ownership Cost: Maintenance-free crankcase and durable internals reduce service intervals and downtime.
• Built-In Convenience: Integrated unloader and chemical injector remove the need for aftermarket kits.
• Consistent Performance: 2.2 GPM at 2,400 PSI delivers repeatable results across a range of tasks.
• Simple Installation: F7 flange and 7/8″ vertical shaft match common engine mounts for fast replacement.

Typical Applications

• Home exterior washing — driveways, patios, walkways, and siding
• Vehicle cleaning — cars, motorcycles, ATVs, small commercial vehicles
• Property upkeep — decks, fences, outdoor furniture, and storage buildings
• Light commercial tasks — storefronts, small rental units, light-duty maintenance fleets
• Small equipment and tool cleaning in shops and garages
