RKA4G30ESX-F17 Triplex Pump | 4.0 GPM 3000 PSI F17

Product Summary

• RKA4G30ESX-F17 left-hand triplex ceramic plunger pump engineered for electric-motor pressure washer systems with specialized layouts.
• Delivers 4.0 GPM at 3000 PSI at 1750 RPM for industrial-grade cleaning power with cooler, longer-life operation.
• ESX-F17 left-hand shaft configuration supports direct mounting on NEMA 182–184 motors using a 1-1/8″ hollow shaft interface.
• 12,000 ECU output provides efficient cleaning performance for wash bays, fleets, and facility maintenance programs.
• Backed by a 5-year 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-mount ESX-F17 configuration provides rigid coupling to compatible electric motors without belt alignment.
• Left-hand orientation supports mirror-image frames, dual-pump systems, and space-driven equipment layouts.
• Optimized for stationary wash systems where uptime, re-buildability, and consistent performance matter.

• Warranty coverage supports commercial and industrial cleaning operations.

Operating Guidance

• Confirm motor compatibility with the NEMA 182–184 ESX-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 under load.
• Follow the operator’s manual for break-in procedure, oil service intervals, and winterization.

Service & Maintenance

• 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 to plan rebuild kits and minimize downtime during service events.
