• Manufacturer warranty and technical support for dependable long-term use.

How the RRA55G26E-F17 Works

• Uses a triplex plunger mechanism where three ceramic plungers move in sequence to generate high-pressure water flow.
• During the intake stroke, inlet valves open to draw water into the manifold; during the discharge stroke, outlet valves open to release pressurized water to the system.
• This positive-displacement design produces a steady, pulse-free flow, essential for even, efficient cleaning in commercial applications.
• At 1,750 RPM, the pump is optimized for electric motor use, reducing heat, vibration, and component wear while ensuring quieter performance.
• The forged brass manifold resists corrosion and pressure fatigue, while ceramic plungers and stainless valves provide long-lasting reliability in high-demand environments.

Benefits & Advantages

• High-flow electric performance: 5.5 GPM at 2,600 PSI covers large surface areas and high-volume cleaning tasks efficiently.
• Electric motor optimized: 1-1/8″ hollow shaft and 1,750 RPM speed are ideal for direct NEMA 56C motor mounting.
• Durable, commercial-grade build: Ceramic plungers, forged brass head, and stainless valves are designed for continuous operation.
• Smooth and quiet: Low-speed triplex design minimizes noise and vibration while maintaining steady pressure.
• Low maintenance: External oil sight glass and vented dipstick simplify routine checks and servicing.
• Versatile installation: Well suited for fixed wash stations, OEM skid systems, and high-volume electric pressure washer builds.

Typical Applications

• Industrial facilities: Plants, warehouses, shipyards, and factories requiring reliable electric-powered washdown.
• Fleet & equipment washing: Buses, trucks, trailers, heavy machinery, and service vehicles in centralized wash bays.
• Commercial cleaning: Garages, detailing bays, schools, campuses, retail centers, and other high-traffic facilities.
• OEM installations: Skids, cabinet washers, stationary electric pressure washer systems, and custom industrial builds.
• Agricultural washdown: Barns, pens, tractors, and equipment cleaning where electric power is preferred over gas.

Installation & Maintenance Tips

• Match motor specifications: Designed for NEMA 56C motors with 1-1/8″ shafts running at 1,750 RPM—ensure proper alignment during mounting.
• Ensure clean water supply: Use a properly sized inlet filter and hose to prevent cavitation and premature seal wear.
• Install an appropriate unloader valve: Correct pressure regulation protects the pump and ensures safe operation.
• Follow oil service intervals: Change crankcase oil after the break-in period, then at recommended intervals for optimal performance.
• Seasonal inspections: Check seals, plungers, and valves regularly to maintain peak performance in continuous-duty environments.
