RKA4G30E-F17 4.0 GPM 3000 PSI | F17 Shaft Triplex

Product Summary

• RKA4G30E-F17 direct-mount triplex ceramic plunger pump engineered for electric-motor pressure washer systems.
• Delivers 4.0 GPM at 3000 PSI at 1750 RPM for industrial-grade cleaning power with cooler, longer-life operation.
• F17 motor mount with 1-1/8″ hollow shaft provides a clean, rigid coupling to compatible electric motors.
• 12,000 ECU output supports high-impact cleaning performance for productive wash cycles.
• Backed by a 5-year limited manufacturer warranty for professional and industrial duty environments.

System Configuration

• Triplex crankshaft-drive architecture designed for smooth flow delivery and stable pressure under load.
• Low-speed 1750 RPM platform supports reduced operating temperature and extended seal and bearing life.
• Direct-coupled F17 motor mount eliminates belt alignment requirements and reduces build complexity.
• 1-1/8″ hollow shaft interface supports common electric-motor drive arrangements in fixed installations.
• Optimized for wash bays and stationary systems where consistent performance and rebuildability are required.

• Stainless steel valves support corrosion resistance and consistent seating under load.
• Industrial-duty sealing system designed to retain pressure and reduce leakage over extended runtime.
• Factory assembly and functional verification performed prior to shipment and distribution.

Manufacturing Standards

• Manufactured to industrial-duty triplex pump production standards.
• Designed to meet published performance ratings at 1750 RPM operation.
• Factory test results support commissioning documentation and maintenance records.
• Warranty coverage supports contractor and industrial users running scheduled wash programs.

Operating Guidance

• Confirm electric motor compatibility with the F17 1-1/8″ hollow shaft interface before installation.
• Use clean water supply and proper inlet filtration to protect valves, packings, and plungers.
• Verify supply flow is adequate for 4.0 GPM operation before extended runtime.
• Pair with an unloader/regulator sized to 4.0 GPM and set pressure at the nozzle for accurate control.
• Follow the operator’s manual for break-in procedure, oil service intervals, and winterization.

Service & Maintenance of RKA4G30E-F17

• Monitor oil level through the sight glass and service oil per manufacturer intervals.
• Inspect plumbing connections for leaks and air ingestion during routine inspections.
• Keep inlet strainers clean to prevent cavitation and pressure instability.
• Inspect packings and valves on a schedule matched to duty cycle and water quality.
• Use the parts schematic and test results to support rebuild planning and maintenance tracking.

Applications

• Commercial and industrial electric pressure washer builds and stationary wash bays.
• Fleet and vehicle washing systems requiring consistent output and extended runtime.
• Concrete, masonry, and surface preparation programs.
• Agricultural equipment cleaning and facility washdown.
• Construction equipment washdown and general industrial maintenance cleaning.
