AR16 Yuken Variable Displacement Piston Pump 16MPa

Product Overview

The AR series from Yuken comprises variable-displacement axial piston pumps, including AR10, AR16, AR22 and specific codes such as AR16-FR01CK10Y-1048. Featuring a swash-plate design with pressure-compensator control, these pumps are engineered for lower noise, higher efficiency and more compact size. Manufactured to exact OEM dimensions and interfaces for 100% drop-in interchangeability. Every unit undergoes 100% simulated operating-condition testing to verify flow, pressure and sealing integrity for machine tools, presses and industrial hydraulic systems.

Key Technical Advantages

• Low-noise high-efficiency design: Optimized on proven Yuken technology for significantly reduced noise at full cut-off and high volumetric efficiency, delivering energy savings.
• Compact lightweight construction: Aluminum housing and precision machining achieve substantial size and weight reduction versus previous A-series models, ideal for space-constrained installations.
• Precise pressure-compensator control: Fast response with minimal overshoot automatically adjusts displacement to load, reducing relief losses.
• 100% drop-in interchangeability and simulated testing: Mounting flange, shaft end and ports match OEM exactly; full duty-cycle validation before shipment ensures sealing integrity and extended service life.

Application Areas

CNC machine tools, press brakes, punching machines, hydraulic presses, injection molding machines, industrial power units and any equipment requiring stable pressure with low noise.

Expert Maintenance Tips

Install with the filling port facing upward and pre-fill the case with hydraulic oil before first start-up. Use ISO VG32 or 46 anti-wear hydraulic oil and maintain system cleanliness. When adjusting pressure, ensure full cut-off never exceeds intermittent rating; lock the nut after setting. Regularly check for leakage and noise; avoid prolonged cavitation or overspeed. Perform flow and pressure verification according to the official manual.
