RKV4G30E-F17 | 4.0 GPM 3000 PSI Triplex Pump, F17 Shaft

RKV4G30E-F17 — 4.0 GPM 3000 PSI Electric Motor Triplex Pump

• Electric-motor-driven triplex plunger pump designed for systems that require 4.0 GPM at 3000 PSI in a compact, high-speed package.
• Direct-coupled F17 flange and 1-1/8″ hollow shaft interface NEMA 182–184 frame electric motors without intermediate belt drives or gearboxes.
• Operating speed of 3400 RPM delivers approximately 12,000 Effective Cleaning Units (ECU), supporting demanding cleaning tasks in commercial and industrial environments.
• Nickel-plated head, ceramic plungers, and stainless valves are specified for continuous-duty wash bays, equipment cleaning stations, and concrete maintenance systems.

Performance and Duty Profile

• 4.0 GPM at 3000 PSI provides a balance of flow and impact suitable for single-gun electric skids and fixed wash stations.
• ECU output around 12,000 supports fast cleaning on vehicles, machinery, and flatwork without oversizing the electric motor or plumbing.
• Rated for frequent operation in commercial facilities, fleet depots, and industrial shops where electric power is preferred over engine-driven systems.
• Performance envelope is well matched to medium-size surface cleaners, rotary nozzles, and lances configured for 4.0 GPM service.

Flow, Pressure, and Cleaning Efficiency

• 4.0 GPM provides enough volume to feed surface tools and undercarriage cleaners while still being manageable on standard 3/8″ high-pressure hose runs.
• 3000 PSI working pressure is suitable for concrete, steel, and vehicle surfaces when correct nozzle sizes and cleaning procedures are used.
• High ECU output supports shorter cleaning cycles, which is critical in commercial car wash tunnels, detail bays, and equipment wash pads.
• Stable pressure curve helps maintain uniform spray patterns and predictable impact at the gun or surface tool.

Electric Motor Mounting and Drive Interface

• Designed for direct mounting to NEMA 182–184 frame electric motors using the F17 flange standard.
• RKV4G30E-F17 – 1-1/8″ hollow shaft slides over the motor shaft, transmitting torque without belts, pulleys, or external couplers when properly installed.
• Direct-drive layout reduces footprint, rotating mass, and alignment complexity, improving reliability in permanent installations and skid packages.
• Electric power integration supports indoor use, noise reduction, and low daily maintenance compared with engine-driven systems.

F17 Flange and 1-1/8″ Hollow Shaft Details for RKV4G30E-F17

• F17 flange pattern aligns with standard 182–184 frame motor faces, allowing the pump to be bolted directly to the motor end bell.
• 1-1/8″ hollow keyway shaft is engineered to match common motor shaft dimensions, maintaining concentricity and minimizing radial loading when installed correctly.
• Direct coupling helps maintain accurate alignment over time, reducing vibration and extending bearing and seal life.
• Compact motor-and-pump package simplifies skid frame design, enclosure sizing, and guard layout.

Construction and Materials

• Triplex plunger design with precision crankshaft delivers smooth hydraulic output and reduced pulsation compared to basic piston or axial configurations.
• Nickel-plated pump head provides added corrosion resistance in wet, chemical, and high-moisture environments.
• Ceramic plungers and stainless steel valves are specified for long-term service under repeated high-pressure cycling.
• Heavy-duty crankcase and bearings are sized for continuous-duty operation at 3400 RPM when properly lubricated and supported.

Triplex Power Section and Wet End

• Three-plunger arrangement smooths flow and limits pressure spikes, protecting hoses, fittings, and accessories in high-duty service.
• Ceramic plungers provide a hard, stable sealing surface for packings, reducing wear and helping maintain volumetric efficiency.
• Stainless valves seat consistently, supporting clean suction and discharge events and stable pressure build at the gun.
• Nickel-plated head maintains port geometry and sealing faces in harsh washdown environments, improving long-term reliability.

System Integration and Control

• Intended for use with external unloaders, regulators, and safety valves sized for 4.0 GPM at 3000 PSI.
• Compatible with common industrial manifolds, hose sets, and accessories used on electric wash skids and fixed plant systems.
• Plumbs easily into multi-gun manifolds or single-gun stations when paired with correctly sized bypass and distribution piping.
• Works with hot or cold water feeds within the manufacturer’s temperature ratings when equipped with appropriate protection.

Plumbing, Protection, and Best Practices

• Inlet plumbing should provide generous flow with low restriction, ideally via a properly vented supply tank and suitable filtration.
• Discharge hose, gun, and fittings must be rated for at least 3000 PSI with appropriate safety margin and temperature capability.
• Unloader and relief devices should be adjusted to the target working pressure, protecting the system from over-pressurization and dead-heading.
• Bypass return and thermal protection should be configured to prevent excessive water temperature during extended trigger-off periods.

Service, Maintenance, and Documentation

• RKV4G30E-F17 Pump is designed for field service with accessible fasteners and clearly defined seal, valve, and plunger groups.
• Routine maintenance typically includes oil changes, seal and valve inspection, and verification of motor alignment and bolt torque.
• Documentation and exploded views support accurate identification of rebuild kits and replacement components.
• Five-year manufacturer warranty underscores the expected service life when the pump is installed and maintained according to guidelines.

Routine Checks and Lifecycle Planning

• Daily checks should confirm oil level and clarity, review for leaks, and verify stable operating pressure at the gun.
• Scheduled service intervals can be tied to motor run hours, allowing planned seal and valve maintenance before performance degrades.
• Proper recordkeeping on service events helps maintain fleet-wide reliability for facilities running multiple electric skids or bays.
• With correct installation, water supply, and control hardware, the pump supports long-term operation in fixed industrial and commercial environments.

Applications and Use Cases for RKV4G30E-F17

• Electric-powered car and truck wash systems in service centers, dealerships, and fleet depots.
• Concrete surface cleaning in garages, wash bays, loading docks, and warehouse aisles using compatible surface tools.
• Industrial equipment and machinery washdown for factories, maintenance shops, and processing facilities.
• Commercial pressure washing contractors operating electric skids in noise- or emission-sensitive locations.
• Warehouse and factory maintenance cleaning programs that require consistent output from fixed electric wash stations.
