RKA45G40HN-SX LH Triplex Pump | 4.5 GPM 4000 PSI

Product Summary for RKA45G40HN-SX

• RKA45G40HN-SX left-hand triplex plunger pump engineered for specialized and mirror-image system layouts.
• Delivers 4.5 GPM at 4000 PSI at 1750 RPM for high-output cleaning with reduced heat and wear.
• Left-hand (SX) crankshaft orientation supports dual-pump and space-constrained industrial frames.
• 18,000 ECU output provides strong impact force and fast cleaning on heavy soils.
• Backed by a 5-year manufacturer warranty for professional and industrial duty cycles.

System Configuration

• Triplex crankshaft-drive architecture designed for smooth, low-pulsation delivery under sustained load.
• Low-speed 1750 RPM platform supports cooler operation and extended seal and bearing life.
• Left-hand (SX) crankshaft configuration enables mirror-image mounting and balanced multi-pump systems.
• 24 mm solid crankshaft supports belt-drive layouts and controlled-speed installations.
• Optimized for industrial rigs, wash bays, and OEM frames requiring directional shaft orientation.

Operating Guidance for RKA45G40HN-SX

• Confirm belt alignment, pulley condition, and guarding prior to startup.
• Use clean water supply and proper inlet filtration to protect valves, packings, and plungers.
• Verify supply flow is adequate for 4.5 GPM operation before extended runtime.
• Pair with an unloader/regulator sized to 4.5 GPM and set pressure at the nozzle.
• Follow the operator’s manual for break-in, oil service intervals, and winterization.

Service & Maintenance

• Monitor oil level through the sight glass and service oil per manufacturer intervals.
• Inspect inlet strainers regularly to prevent cavitation and pressure instability.
• Check fittings and plumbing connections for leaks and air ingestion.
• Inspect packings and valves during scheduled maintenance intervals.
• Use the parts schematic to plan rebuild kits and minimize downtime.

RKA45G40HN-SX Applications

• Industrial equipment and plant cleaning operations.
• Concrete surface preparation, restoration, and large-area cleaning.
• Vehicle and fleet wash systems requiring high-output performance.
• Professional contractor pressure-washing rigs and wash bays.
• Custom OEM and dual-pump systems requiring left-hand shaft orientation.
