A3HSeries High Pressure Variable Displacement Piston Pumps

New pump series for the industrial and mobile markets. Features a load sense compensator, 4000 PSI rating, and higher shaft speeds.

• Variable displacement piston pumps offer high pressure, high performance in a simple and compact package.
  High Pressure: 35 MPa (5080 PSI)
• High volumetric efficiency
• These pumps maintain a high volumetric efficiency, even at a pressure of 35 MPa (5080 PSI).
• Available in a wide range of displacements
• Seven models are available in displacements ranging of 16.3 to 180.7 cm3/rev (.995 to 11.03 cu. in./rev).

“A3H” Series High Pressure Variable High Pressure Displacement Piston Pumps

Features：

●High performance at maximum pressure
35 MPa

Volumetric efficiency is over 95% and overall
efficiency is more than 90% at 1800 r/min.

● Compact size

A3H series are compact in size because
output / mass ratio is large.

Specifications：

★1. Consult Yuken when pump is used over rated pressure because there is a restriction on operating condition.
★2. The maximum shaft speeds shown in the above table are at suction pressure 0 kPa.
★3. The table above shows specifications for using petroleum based oils.
Pumps (customized design) for special fluids are also available. Their operating pressure and maximum shaft speed however differ from the
values in the table above depending on the fluid type.
Range of operating temperature and viscosities may differ from those of petroleum based oils due to their characteristics.
