Product Overview
▔▔
Yuken Hydraulic Piston Pumps-most notably the renowned AR Series and A Series variable displacement swashplate-type piston pumps-are world leaders in industrial fluid power. Known for their exceptional volumetric efficiency, ultra-low noise levels, and robust construction, Yuken pumps deliver precise hydraulic performance while reducing overall power consumption.
Key Advantages
▔▔-
High Energy Efficiency: Advanced swashplate and port plate design minimizes internal leakage, reducing energy loss and thermal build-up.
Ultra-Low Noise: Optimized internal fluid dynamics dramatically dampen operating noise, ideal for noise-sensitive indoor manufacturing environments.
Compact & Lightweight: Premium alloy housings provide maximum strength and pressure resistance without adding excess bulk.
Flexible Control Options: Available with pressure compensator controls, proportional electro-hydraulic controls, load sensing, and dual-pressure setups.
Proven Reliability: Precision-machined components ensure long service life even under demanding high-pressure continuous operations.

FAQ
▔▔Q1: What is the main difference between Yuken AR Series and A Series piston pumps?
The AR Series is specifically designed for lighter-duty applications requiring lower pressure (up to 16 MPa) with an emphasis on low noise, lightweight construction, and cost efficiency. The A Series is designed for heavier industrial usage, handling higher operating pressures (up to 28 MPa) and offering larger displacement capacities up to 145.2 cm³/rev.
Q2: What type of hydraulic oil is recommended for Yuken piston pumps?
Yuken pumps perform best with premium petroleum-based anti-wear hydraulic oils (ISO VG 32, 46, or 68 depending on operating ambient temperature). Maintain fluid viscosity between 15 and 400 mm²/s (cSt) and ensure oil cleanliness meets ISO 4406 Class 17/14/11 or better.
