RG1528HN 4.0 GPM 4000 PSI | 1450 RPM Triplex Pump

RG1528HN — 4.0 GPM 4000 PSI Triplex Pump, 1450 RPM, Nickel-Plated Head

• The RG1528HN is a commercial-grade triplex plunger pump built for demanding, continuous-duty cleaning environments where reliability and consistent performance are essential.
• Delivering 4.0 GPM at 4000 PSI while running at a slow 1450 RPM, it provides the impact needed for industrial washing without the excessive heat, vibration, and wear associated with higher-speed pumps.
• The nickel-plated head offers enhanced corrosion resistance in wash bays, outdoor installations, and applications with frequent water exposure, extending service life and maintaining sealing integrity.
• Designed for integration into belt-drive, gearbox, and custom equipment configurations used by contractors, municipalities, fleet facilities, and industrial operations.

Performance and Operating Characteristics

Flow, Pressure, and Speed

• RG1528HN outputs 4.0 gallons per minute for reliable coverage when cleaning large vehicles, machinery, and concrete areas.
• Rated for 4000 PSI to provide aggressive cleaning power for removing grease, compacted mud, coatings, and heavy industrial residues.
• Operates at 1450 RPM to reduce internal turbulence, minimize wear on bearings and seals, and improve overall pump longevity in heavy-duty environments.
• Maintains stable performance for surface cleaners, rotary nozzles, and long hose runs without excessive pressure fluctuation.

Triplex Plunger System

• Triplex design uses three plungers working in sequence to create a smooth, pulse-reduced flow ideal for precise cleaning work and tool stability.
• Precision ceramic plungers resist scoring, heat, and chemical attack within rated limits, providing long service life under repetitive high-pressure operation.
• Quality packings and seals are arranged to handle industrial temperature swings and pressure cycles common in daily multi-hour cleaning sessions.
• Stainless-steel valve assemblies maintain clean seating for efficient flow and reliable pressure buildup across a wide range of applications.

Construction and Material Advantages

Crankcase and Driveline Components

• Heavy-duty crankcase casting provides structural rigidity to support long-term reliability and stability during high-load operation.
• The 24 mm keyed solid crankshaft integrates easily with V-belts, Poly Chain belt systems, or reduction gearboxes used in professional wash setups.
• Oversized bearings support the shaft under continuous load, helping maintain alignment and reducing the risk of premature failure.
• Oil bath lubrication with a sight glass and vented dipstick ensures proper lubrication checks, preventing overheating and excessive wear.

Nickel-Plated Head and Wet-End Design – RG1528HN

• Nickel-plated manifold offers enhanced resistance to corrosion, scale, moisture, and chemical exposure, protecting sealing surfaces and threaded ports.
• Precision machining supports correct alignment of valves, packings, and plungers, contributing to smoother performance and longer maintenance intervals.
• Wet-end components are engineered for environments where water quality, detergents, and variable temperature conditions are part of normal operation.
• The durable design supports continuous-duty cycles common in fleet maintenance shops, rental yards, and industrial wash stations.

Installation, Service, and Maintenance

System Integration

• Pump’s 24 mm solid shaft works seamlessly with belt-drive and gearbox configurations used in mobile rigs, wash bays, and fixed industrial installations.
• Inlet and discharge port layout accommodates standard plumbing arrangements, making it easier to retrofit into existing systems.
• Compatible with unloaders, regulators, and safety valves commonly used in high-pressure commercial cleaning systems.
• Intended for mounting on skids, wall racks, trailers, or custom frames with planned access for maintenance and inspection.

Routine Maintenance

• Pre-filled crankcase oil speeds initial setup, and the integrated sight glass allows quick verification of oil level before each shift.
• Vented dipstick prevents pressure buildup in the crankcase and helps maintain clean lubrication flow for bearings and journals.
• Seal kits an
