AR16-F-R-01-B-20 Yuken Variable Piston Pump 15.8cc 16MPa

Product Overview

The AR16 series (typical models AR16-F-R-01-B-20, AR16-FR01CK-10Y, AR16-FR01BS-22, AR16-FR01C-22) is a Yuken AR-series variable-displacement axial piston pump with pressure-compensator control for open-circuit applications. Flow automatically adjusts according to system pressure for energy-efficient operation. The unit offers 100% drop-in interchangeability with genuine Yuken pumps—no piping or mounting modifications required. Every unit undergoes full simulated operating-condition testing to guarantee high volumetric efficiency (>98%), low noise and long service life at rated pressure.

Key Technical Advantages

1. Precision-machined swashplate and piston assembly achieve volumetric efficiency over 98% and overall efficiency over 90%, delivering significant energy savings.
2. Low-noise design provides quieter operation than the conventional A-series at both full flow and full cut-off, ideal for noise-sensitive environments.
3. Fast-response pressure compensator with sharp cut-off characteristics automatically adjusts flow to load, reducing heat generation and power consumption.
4. Smaller size and lighter weight (approximately 60–75% of the older A16) facilitate installation in space-constrained equipment.
5. 100% interchangeability plus full operating-condition testing ensures exact match of mounting dimensions, ports and control characteristics with original Yuken AR16 units, minimising downtime.

Application Areas

Designed for open-circuit systems in machine tools, injection moulding machines, hydraulic power units, industrial presses, small construction machinery, marine hydraulics and other applications requiring medium-pressure variable flow with energy-efficient operation.

Expert Maintenance Tips

1. Install the pump with the filling port at the top; confirm clockwise rotation (R) and precise flange alignment to avoid radial loads.
2. Fully bleed the system before first start-up. Use ISO VG32 or VG46 anti-wear hydraulic oil; maintain cleanliness at NAS 10 or better.
3. Periodically ensure the drain line is unrestricted (recommended inside diameter ≥8.5 mm) and case pressure remains within limits; when adjusting pressure, never allow full cut-off pressure to exceed the intermittent maximum.
4. When changing filters and oil, inspect the pistons and port plate for wear. Perform preventive maintenance at the end of design life or when flow decreases to maximise hydraulic-system longevity.
