RRA3G35E-F17 | Electric Pressure Washer Pump, 3.0 GPM 3500 PSI

RRA3G35E-F17 Commercial Electric Triplex Pump – 3.0 GPM, 3,500 PSI, 1,750 RPM

Overview

The RRA3G35E-F17 Annovi Reverberi Commercial Pressure Washer Pump is a
high-efficiency electric triplex plunger pump designed for industrial and commercial
cleaning systems. Delivering 3.0 GPM at 3,500 PSI while running at a low
1,750 RPM, it provides smooth, reliable performance with reduced wear—ideal
for fixed installations, electric-motor skids, and continuous-duty applications. With a
1-1/8″ hollow shaft and NEMA 56C-style mount, it couples easily to standard
electric motors, making it a dependable choice for OEMs, contractors, and facilities.

How the RRA3G35E-F17 Works

• Triplex plunger mechanism uses three ceramic plungers driven in sequence to draw water through inlet valves and discharge it through outlet valves at high pressure.
• Positive-displacement design produces steady, pulse-free pressure ideal for uniform cleaning performance.
• Low 1,750 RPM operating speed reduces heat, noise, and internal wear compared to high-speed pumps.
• Forged brass manifold resists corrosion and stress from continuous high-pressure operation.
• Ceramic plungers minimize friction and heat buildup, protecting seals and extending service life.

Benefits & Advantages

• Electric-motor optimized: 1-1/8″ hollow shaft and 1,750 RPM speed match common NEMA 56C motors.
• High performance at lower speed: 3.0 GPM at 3,500 PSI with reduced wear and quieter operation.
• Commercial-grade durability: Ceramic plungers, stainless valves, and forged brass head for long service in harsh environments.
• Smooth output: Triplex design delivers consistent water pressure with minimal pulsation.
• Low maintenance: External sight glass and vented dipstick simplify routine oil checks.
• Versatile use: Ideal for fixed electric wash systems, cabinet washers, and wall-mount units.

Typical Applications

• Industrial facilities: Washdown in plants, warehouses, factories, and shipyards.
• Fleet & equipment washing: Electric-powered wash stations for trucks, buses, trailers, and service vehicles.
• Commercial cleaning bays: Detail shops, garages, campuses, and property-maintenance stations.
• OEM systems: Electric skids, cabinet washers, and stationary systems requiring high performance at low RPM.
• Agricultural washdown: Barns, pens, tractors, and implements where electric service is available.

Installation & Maintenance Tips

• Match pump to a NEMA 56C electric motor with 1-1/8″ shaft at 1,750 RPM and verify alignment before operation.
• Use adequate inlet filtration and supply line sizing to prevent cavitation and extend seal life.
• Pair the pump with a quality unloader valve for safe pressure regulation and bypass protection.
• Change crankcase oil after the initial break-in period, then at regular service intervals.
• Inspect seals, plungers, and valves periodically in continuous-duty environments to maintain peak performance.
