RGA4G30HN-EC | Triplex Pump, 4 GPM 3000 PSI, 1750 RPM, Electric Clutch

RGA4G30HN-EC Electric-Drive Triplex Pump with Integrated Clutch

• The RGA4G30HN-EC is a commercial-duty triplex plunger pump with an integrated electric clutch, engineered for electric-motor-driven wash systems that require controlled engagement, reduced idle wear, and consistent 3,000 PSI performance.
• Rated at 4.0 GPM and 3,000 PSI at 1,750 RPM, it delivers solid cleaning power while operating in a low-speed range that supports long component life and stable operation.
• The electric clutch allows the pump to be engaged only when pressure is required, reducing unnecessary runtime, lowering heat buildup, and helping extend the life of seals, bearings, and drive components.
• With a 24 mm solid shaft, the pump is built to integrate cleanly with common electric motor couplings, gear reducers, and mounting arrangements used in industrial and fleet wash equipment.
• Internal flow passages and valve layout are designed for low pulsation, giving operators a steady spray pattern at the gun and improving the performance of surface cleaners and other high-demand tools.
• This configuration is suited for vehicle wash bays, municipal fleets, contractor rigs, and rental yards that want a controllable, energy-conscious pump package rather than a continuously running unit.

Performance & Operating Characteristics

• RGA4G30HN-EC Delivers 4.0 GPM at 3,000 PSI, providing a strong balance of cutting force and flow volume for equipment washing, vehicle cleaning, and general facility maintenance.
• Low-speed 1,750 RPM operation reduces friction and internal temperature rise, supporting longer lubricant life and more predictable wear patterns compared to higher-speed designs.
• Triplex plunger architecture provides smoother, low-pulsation output than wobble-plate or axial pumps, reducing shock loading on hoses, guns, and fittings.
• Stable pressure delivery helps maintain consistent nozzle performance over long hose runs, making the pump suitable for fixed bays and extended-reach wash systems.
• Capable of handling frequent start–stop duty cycles when paired with a properly sized unloader and thermal management, typical of wash bays and service centers.
• 4.0 GPM capacity is well suited to single-gun wash stations, moderate-size surface cleaners, and standard contractor-grade lances when sized correctly.

Electric Clutch Function & System Control of RGA4G30HN-EC

• The RGA4G30HN-EC integrated electric clutch allows the pump to be engaged and disengaged on command, typically from a control panel, PLC, or interlock tied to wash equipment.
• Disengaging the pump during idle periods prevents unnecessary load on the motor, reducing energy consumption and lowering wear on the rotating group.
• Clutch control can be coordinated with system logic, such as bay selection, trigger signals, or conveyor status in automated or semi-automated wash environments.
• This design reduces heat buildup in bypass conditions compared to pumps that remain fully engaged and recirculating whenever the motor runs.
• By limiting runtime to actual cleaning periods, the clutch helps extend the life of seals, valves, and bearings, improving total cost of ownership for high-utilization systems.
• The clutch-based architecture supports safer maintenance and service procedures, as the pump can be positively disengaged when electrical lockout is applied.

Construction, Materials & Pump Design

• Industrial triplex plunger RGA4G30HN-EC design uses ceramic plungers to provide a hard, polished surface that resists scoring and promotes consistent sealing over long operating intervals.
• Stainless steel valves are specified for reliable seating and resistance to corrosion under typical wash-chemical and water conditions.
• Premium seal sets are selected for continuous-duty service at 3,000 PSI, supporting regular stop–start operation in professional environments.
• Heavy-duty crankcase with splash lubrication is pre-filled with break-in oil, allowing immediate installation, alignment, and testing once plumbed and wired.
• An integrated oil sight glass and vented dipstick provide straightforward monitoring of crankcase level and condition, making daily checks fast for operators and maintenance staff.
• The 24 mm solid shaft is sized for common couplers and drive components, simplifying mechanical integration with matched electric motors and gear packages.

Reliability, Serviceability & Maintenance Practices

• RGA4G30HN-EC Low-speed 1,750 RPM operation and clutch-controlled engagement reduce vibration, mechanical shock, and unnecessary wear on the drivetrain and mounting structure.
• Wet-end components are arranged for access with standard tools, enabling valve, seal, and plunger service without specialized fixtures or dedicated shop equipment.
• Routine maintenance tasks—oil changes, inlet strainer inspection, unloader verification—can be built into normal service intervals for fleets and facilities.
• Proper inlet plumbing, including correctly sized suction lines and filtration, helps prevent cavitation damage and supports long-term reliability.
• Factory testing and documentation support commissioning, troubleshooting, and ongoing service tasks, whether handled in-house or by outside service providers.
• Backed by a 5-year factory warranty when installed and operated within published guidelines, reinforcing its role as a long-term component in commercial wash systems.

Typical Applications & Use Cases of RGA4G30HN-EC

• Vehicle and fleet wash stations for trucks, buses, emergency vehicles, and municipal equipment where on-demand pump control saves energy and reduces wear.
• Rental yard and equipment service centers that operate electric-powered wash bays with variable daily usage and frequent idle periods.
• Mobile contractor rigs using generator or shore power, where selective engagement of the pump helps manage electrical load and equipment life.
• Warehouse and facility cleaning tasks, including machinery washdown, dock area cleaning, and general hard-surface rinsing.
• Municipal maintenance operations supporting public works fleets, utility vehicles, and specialized service equipment.
• OEM and integrator-built systems that require an industrial 4.0 GPM, 3,000 PSI pump with clutch-based control for advanced automation or safety logic.
