YUKEN "A" "AR" "A3H" Series Variable Displacement Piston Pumps
"AR" series variable displacement pump has been developed which the aim of even further the quientness in operation, smaller in size and lighter in mass and based on Yuken technology and engineering which put on market the "A" series pump which has a reputation for its quiet operation and high efficiency.
| Model number | Adjustment Volume MPa (PSI) | Approx. Mass (Flange Mtg.) | Minimum adjustable flow 3 cm /rev (cu.in./rev) |
| AR16 | 2.9 (420) | 9.8 kg (21.6 lbs.) | 6 (.366) |
| AR22 | 5.4 (780) | 9.8 kg (21.6 lbs.) | 8.5 (.519) |
"A" Series Variable Displacement Piston Pumps Use petroleum based oils such as anti-wear type hydraulic oils or R & O (Rust and Oxidation inhibitor) type hydraulic oils equivalent to ISO VG-32 or 46. The recommended viscosity range is from 20 to 400 mm2/s (98 to 1800 SSU) and temperature range is from 0 to 60°C (32 to 140°F),both of which have to be satisfied for the use of the above hydraulic oils.

"A3H" Series Variable Displacement Piston Pumps Volumetric efficiency is over 95% andoverall efficiency is more than 90% at 1800 r/min.are compact in size because output / mass ratio is large.Control Type:”01” “09” “14”.
