★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.
