Series Variable Displacement Piston Pumps
Proportional Electro-Hydraulic Load Sensing Type
■ Specifications
★1. Whenever setting pressure, make sure the full cut-off pressure never
exceeds the maximum intermittent pressure.
★2. When operating the pump exceeding the rated pressure, operating
conditions are restricted. Refer to page 31 for the details.
★3. Specifications of power amplifiers, consult Yuken for details.
★4. The figure mentioned in the above table are those obtained using Yuken's
amplifier.
★5. Step response depends on circuit and operating conditions. Data shown in
the table above is an example based on the condition right.
