“AR” series variable displacement pump has been developed with the aim of even further quientness in operation, smaller size and lighter mass. Based on Yuken technology and engineering, the “A” series pump has a reputation for its quiet operation and high efficiency.
- Compact and Lightweight
- A compact design and an aluminum body ensures a high power to mass ratio.
- Low Noise
“AR” Series Variable Displacement Piston Pumps
Features
● Smaller in Size and Lighter in Mass
As indicated in the dimensional comparison presented
below, the AR16 is smaller than the A16 (32 design). Also,
the mass of AR16 is substantially lighter than the A16.
● Low Noise
The noise level of AR16 has been reduced at full flow and
full cut-off compared with that of the excellent A16 quiet
pump.
Specifications
Model Number Designation
Hydraulic Fluids：
Use petroleum base oils such as anti-wear type hydraulic oils equivalent to ISO VG-32 or 46. The recommended viscosity range is from 20 to 400 mm2/s and temperature range is from 0 to 60 °C, both of which have to be satisfied for the use of the above hydraulic oils.
Control of Contamination：
Due caution must be paid to maintaining control over
contamination of the operating oil which can otherwise
lead to breakdowns and shorten the life of the unit.
Please maintain the degree of contamination within NAS
Grade 10.
The suction port must be equipped with at least a 100 μm
(150 mesh) reservoir type filter and the return line must
have a line type filter of under 10 μm.
