HYD-RK2115 Hydraulic Triplex Pump | 5.5 GPM 2200 PSI

HYD-RK2115 Hydraulic Direct-Drive Triplex Pump Assembly

System Configuration

• Hydraulic motor–driven triplex plunger pump assembly engineered for professional and industrial cleaning systems.
• Built around the Annovi Reverberi RK21.15 pump platform with direct hydraulic drive.
• Designed for applications where hydraulic power is already available and belt drives are undesirable.
• Horizontal configuration supports compact mounting in skids, trailers, and equipment frames.
• Direct-drive layout eliminates belts, pulleys, and gearboxes to reduce vibration and service complexity.

Performance Envelope

• Rated output of 5.5 GPM for consistent high-volume cleaning.
• Standard operating pressure of 2,200 PSI.
• Maximum pressure capability up to 3,000 PSI.
• Target operating speed of 1,450 RPM.
• Balanced flow and pressure profile for industrial washdown and jetting support.

Hydraulic Drive Configuration

• Integrated hydraulic motor matched to the RK21.15 duty point.
• Motor selected for low-speed/high-torque operation under load.
• Hydraulic drive provides smooth torque delivery with minimal pressure fluctuation.
• Direct coupling transfers power efficiently without alignment drift.

HYD-RK2115 Hydraulic Requirements

• Nominal hydraulic motor flow requirement of approximately 7.7 GPM.
• Hydraulic operating pressure requirement of approximately 2,500 PSI.
• Hydraulic ports sized at 1/2″ inlet and outlet.
• System relief valves set to protect motor and circuit at rated pressure.
• Return filtration specified at 10–25 micron with appropriate beta rating.

Pump Assembly Details

• Annovi Reverberi RK21.15 triplex plunger pump.
• Ceramic plungers for extended wear resistance.
• Hardened seals designed for continuous-duty operation.
• Heavy-duty bearings for long service life under hydraulic drive.
• Crankcase pre-filled with pump oil from the factory.
• Integrated oil sight glass for fast visual level inspection.

Water-Side Porting

• Water inlet port sized at 1/2″ FPT.
• Water discharge port sized at 3/8″ FPT.
• Port sizing supports common hose and fitting standards for mobile systems.
• Suction plumbing kept short, straight, and unrestricted from a flooded source.
• Use of anti-collapse suction hose and coarse inlet strainer recommended.

Direct Hydraulic Drive Advantages

• Eliminates belt tensioning and periodic adjustment.
• No belt dust or oversized belt guards.
• Reduced vibration compared with belt or gearbox-driven pumps.
• Improved bearing and seal life through stable centerline alignment.
• Cleaner, more compact installation in confined equipment spaces.

Integration Guidance

• Motor displacement selected to achieve 1,450 RPM at available hydraulic flow.
• Pump speed verified using rpm ≈ 231 × hydraulic GPM ÷ motor displacement (in³).
• Torque verified using torque (lb-in) ≈ displacement (in³) × PSI ÷ 6.283.
• Hydraulic horsepower confirmed using HP ≈ GPM × PSI ÷ 1714.
• Reservoir sized at 2–3× total system flow for heat rejection.
• Oil cooler added for high ambient temperatures or continuous-duty cycles.

HYD-RK2115 Service & Maintenance Access

• Horizontal layout allows clear access to coupling hardware.
• Oil sight glass visible for daily pre-start inspection.
• Fasteners accessible with common hand tools.
• Simplified service routine compared with belt-driven assemblies.
