Performance

The HYD-RK1520-1500 Hydraulic Pressure Washer delivers balanced cleaning capability that combines effective rinsing power with controlled pressure output suitable for sensitive surfaces and daily cleaning operations. Producing 4 gallons per minute at 1500 PSI, the system provides sufficient force to remove mud, grease, oil residue, salt buildup, debris, and contaminants from equipment, vehicles, and work surfaces.

Unlike high-pressure systems designed primarily for aggressive surface stripping, the HYD-RK1520-1500 Hydraulic Pressure Washer focuses on efficient cleaning with reduced overspray and lower risk of surface damage. This makes it ideal for maintenance crews, municipalities, contractors, agricultural operators, and fleet service professionals requiring dependable everyday cleaning performance.

The RK1520 triplex plunger pump is designed for durability and extended service life. Its rigid crankcase construction, oversized bearings, and quality sealing components help support long operating cycles and consistent pressure output under demanding working conditions.

Hydraulic Drive Advantages

The HYD-RK1520-1500 Hydraulic Pressure Washer uses a direct hydraulic drive system that eliminates belts, pulleys, and additional engine components commonly found in traditional pressure washers. This compact coaxial motor and pump layout reduces vibration, simplifies maintenance access, and improves overall system reliability.

Because the unit operates from an existing hydraulic power source, it is especially valuable for mobile service equipment, utility trucks, construction machinery, and industrial systems already equipped with hydraulic circuits. Hydraulic-powered operation also reduces noise levels compared to gasoline-powered units while allowing cleaning performance to remain independent of engine speed fluctuations. The shared base and aligned motor-pump design help preserve shaft alignment during transport and daily operation, improving seal life and reducing bearing wear over time.

Hydraulic Pressure Washer Applications

• Equipment washdown systems
• Fleet vehicle cleaning
• Municipal maintenance operations
• Construction equipment cleaning
• Agricultural machinery washdown
• Shop floor sanitation
• Facility maintenance cleaning
• Loading dock cleaning
• Parks and public works service equipment
• Rental fleet maintenance
• Contractor trailer wash systems
• Industrial mobile cleaning applications

Hydraulic Power Requirements

The host machine’s auxiliary hydraulic circuit must supply 7.5 GPM at 1300 PSI continuously at the motor — approximately 5.7 hydraulic horsepower. Nearly any skid steer, tractor, crane truck, or utility vehicle auxiliary circuit exceeds this requirement. If your available flow is slightly below spec, the pump simply runs proportionally slower; full rated water pressure still requires the full hydraulic supply pressure listed.

Hydraulic Integration Notes

• Confirm hydraulic motor rotation before final installation
• Match hydraulic flow to pump rated operating speed
• Verify proper hydraulic reservoir capacity and filtration
• Use appropriate return-line filtration and oil cooling for continuous duty
• Maintain proper hose bend radius to reduce restriction
• Clamp hydraulic lines securely to reduce vibration wear
• Use proper case drain plumbing if required by motor design
• Set upstream hydraulic relief valves correctly to protect the motor

Water-Side Plumbing & Controls

• Designed for low-restriction inlet plumbing configurations
