RKA35G30E-F17 3.5 GPM 3000 PSI | F17 Shaft Triplex

RKA35G30E-F17 — 3.5 GPM, 3000 PSI Triplex Pump, 1750 RPM, F17 Motor Mount

Overview

The RKA35G30E-F17 triplex plunger pump is a commercial-grade pressure washer pump engineered for dependable performance, long service life, and seamless electric motor integration. Designed around Annovi Reverberi’s proven RKA (228 series) platform, this pump delivers a balanced combination of flow, pressure, and efficiency that makes it ideal for light industrial and commercial cleaning environments. With a rated output of 3.5 gallons per minute at up to 3000 PSI, it provides the cleaning power needed for demanding daily tasks while maintaining controlled water usage and excellent component longevity.

Operating at a low-speed 1750 RPM, the RKA35G30E-F17 significantly reduces internal wear compared to high-speed pumps, helping extend the life of seals, bearings, plungers, and valves. This slower operating speed also contributes to quieter operation, reduced vibration, and lower overall system stress. The result is a pump that performs reliably under continuous-duty conditions, making it a strong choice for commercial wash bays, fleet washing operations, and maintenance facilities.

The direct-drive F17 motor mount allows the pump to bolt directly to compatible NEMA 182–184 frame electric motors with a 1-1/8″ hollow shaft. By eliminating belts and pulleys, the design simplifies installation, reduces alignment issues, and minimizes routine maintenance requirements. This makes the RKA35G30E-F17 especially attractive for operators seeking a clean, compact, and efficient electric pressure washer setup.

Performance & Cleaning Power

With an Effective Cleaning Unit (ECU) rating of 10,500, the RKA35G30E-F17 delivers strong real-world cleaning performance suitable for a wide range of commercial applications. The ECU rating reflects the balance of pressure and flow, ensuring sufficient impact force to remove dirt, grease, and grime while maintaining enough volume to rinse surfaces effectively. This makes the pump well-suited for tasks such as vehicle washing, concrete cleaning, equipment maintenance, and general facility upkeep.

The triplex plunger design provides smooth, consistent water flow with reduced pressure pulsation. Compared to axial cam pumps, triplex pumps are known for superior durability, better efficiency, and longer service intervals. The reduced pulsation also helps protect downstream components such as hoses, unloader valves, and spray guns, improving overall system reliability.

Construction & Durability

The RKA35G30E-F17 is built using high-quality materials selected to withstand the demands of commercial use. The brass pump head offers excellent corrosion resistance and strength, making it suitable for a wide range of water conditions. Ceramic plungers provide superior hardness and wear resistance, ensuring long-term sealing performance even under continuous operation.

Internally, aluminum connecting rods reduce reciprocating mass and help improve efficiency while maintaining strength. The hardened crankshaft and precision-machined components contribute to smooth operation and dependable performance over extended service life. With a maximum operating temperature of 140°F, the pump is well-suited for cold water pressure washing systems commonly used in commercial environments.

Installation & Maintenance

Designed for horizontal mounting, the RKA35G30E-F17 integrates easily into electric-driven pressure washer systems. The F17 flange mount ensures proper alignment with compatible electric motors, reducing installation time and minimizing setup errors. The pump ships factory pre-filled with break-in oil, allowing for immediate startup right out of the box.

Routine maintenance is straightforward and user-friendly. An integrated oil sight glass allows quick visual inspection of oil levels, while the vented dipstick ensures proper crankcase ventilation. With an oil capacity of 15 ounces, regular oil changes are simple and economical. These features help reduce downtime and make preventative maintenance easy for operators and service technicians alike.
