RKA4.8G30E-F17 4.8 GPM 3000 PSI | F17 Shaft Triplex

RKA4.8G30E-F17 Electric-Drive Triplex Pump

• Heavy-duty triplex plunger pump engineered for electric-driven pressure washer systems where uptime and repeatable output are required.
• RKA4.8G30E-F17 rated 4.8 GPM at 3,000 PSI for strong cleaning impact with the volume to support surface cleaners and long hose runs.
• Serviceable pump platform with rebuild support for commercial and industrial wash environments.
• Low-pulsation delivery stabilizes spray pattern quality and reduces cyclic stress on hoses, fittings, and accessories.
• Low-speed 1,750 RPM operation supports longer bearing life, extended seal intervals, and predictable maintenance planning.
• Well suited for facilities standardizing electric wash systems across multiple bays, skids, or cabinets.

Performance & Operating Characteristics RKA4.8G30E-F17

• Delivers 4.8 GPM at 3,000 PSI for 14,400 ECU cleaning productivity in demanding maintenance and wash work.
• Triplex plunger design provides a smoother pressure curve than axial or wobble-plate designs for steadier nozzle behavior.
• Operates at 1,750 RPM to keep oil temperature, friction, and internal stress within stable limits during long duty cycles.
• Supports surface cleaners, undercarriage tools, rotary nozzles, and extended wands when system components are rated and sized for 3,000 PSI.
• Handles frequent stop–start wash-bay operation when paired with a properly sized unloader and correct bypass routing.
• Maintains controlled trigger feel for detailed equipment cleaning and vertical surface washing.

RKA4.8G30E-F17 F17 Motor Mounting & System Integration

• F17 motor mount couples directly to NEMA 182/184 frame electric motors to eliminate belts, pulleys, and separate alignment steps in many builds.
• Direct mounting reduces drivetrain losses, removes belt wear items, and simplifies guarding and safety compliance in fixed installations.
• Compact pump–motor footprint supports wall frames, skids, cabinets, and pump decks where space is limited.
• Common HE-F17 layout compatibility helps reduce retrofit time when upgrading older pump platforms to a modern triplex design.
• Integrates with standard unloaders, regulators, safety relief valves, thermal dump valves, and filtration for repeatable system packages.
• Flexible inlet/discharge orientation supports clean plumbing runs to reels, manifolds, and filtration assemblies.

Construction, Materials & Mechanical Features

• Ceramic plungers provide a hard, smooth surface to protect seals and maintain clearances under thermal and pressure cycling.
• Forged brass manifold supports strength and corrosion resistance with properly treated water and typical industrial detergents.
• Stainless steel valves support reliable seating across repeated cycles for consistent discharge pressure.
• Rigid crankcase with splash lubrication arrives pre-filled with break-in oil for straightforward commissioning.
• Integrated oil sight glass enables quick visual checks of oil level and condition during routine inspections.
• Vented dipstick supports crankcase breathing and straightforward oil service intervals.

RKA4.8G30E-F17 Reliability, Serviceability & Maintenance Practices

• Low-speed geometry reduces vibration transmitted into frames and piping to help prevent fatigue, loose connections, and nuisance leaks.
• Service access supports routine valve, seal, and plunger work using standard tools for in-house or field rebuilds.
• Proper inlet filtration and correctly sized suction lines improve resistance to cavitation damage in daily operation.
• Maintenance schedules can be aligned to runtime logs for planned oil service, seal inspection, and valve upkeep.
• Stable hydraulic behavior supports smooth unloader function and reduces pressure spikes and accessory stress.
• Supported by limited manufacturer warranty when installed and maintained to specification.

Typical Applications & Use Cases for RKA4.8G30E-F17

• Fleet wash bays cleaning trucks, trailers, buses, and delivery vehicles on repeat schedules.
• Industrial surface cleaning of concrete floors, docks, containment areas, and yard surfaces.
• Construction and agricultural machinery cleaning for loaders, excavators, skid steers, tractors, and implements.
• Commercial property care for sidewalks, approaches, drive lanes, patios, and storefronts.
• Indoor electric wash stations in workshops, garages, distribution centers, and service facilities requiring exhaust-free operation.
• General-purpose wash systems in rental yards, public works departments, and service companies needing a reliable 3,000 PSI electric-drive pump core.
