RK1528HN-VXCR | Gearbox Pump, 4 GPM 4000 PSI, Engine Mount

Overview

The RK1528HN-VXCR Pressure Washer Pump is a heavy-duty, professional-grade pump engineered for contractors and facilities that need consistent power, long service life, and easy installation. Delivering 4.0 GPM at 4,000 PSI at a smooth 1450 RPM, this model provides high pressure while running at reduced speed to minimize heat, vibration, and internal wear. A factory-installed gearbox with engine mount ensures perfect alignment with common gas engines, improving reliability and reducing setup time.

Built with a forged brass manifold, ceramic plungers, stainless steel valves, and VX (Viton) seals, the RK1528HN-VXCR is designed for continuous-duty industrial environments where chemical resistance, heat tolerance, and durability are essential.

How the Pump Works

The RK1528HN-VXCR uses a triplex plunger design to produce a steady, low-pulsation flow of high-pressure water. The gearbox reduces engine speed to the pump’s ideal 1450 RPM operating range, lowering heat output and bearing load for long-term durability. Stainless steel valves ensure precise sealing, while the forged brass manifold resists deformation and corrosion under continuous pressure.

The VX (Viton) seals offer superior chemical and thermal resistance, allowing this pump to handle aggressive detergents and higher-temperature water where standard Buna or NBR seals would fail. Routine servicing is made easy with an oil sight glass, vented dipstick, and accessible packings.

Benefits of RK1528HN-VXCR

• Plug-and-play installation thanks to the factory-installed gearbox and engine mount.
• High pressure at low RPM for reduced vibration and extended component life.
• Chemical & heat resilience from Viton seals and corrosion-resistant internals.
• Durable construction with ceramic plungers and stainless steel valves.
• Easy serviceability via oil sight glass, vented dipstick, and accessible wet-end components.
• Proven reliability backed by a 5-year commercial warranty.

Typical Use Cases

• Food-grade & USDA-regulated sanitation washdown
• Coastal/marine operations with high corrosion exposure
• Fire departments and municipal fleets
• Industrial/environmental services (degreasing, spill cleanup, surface prep)
• Commercial mobile pressure washing rigs
