Series Variable Displacement Piston Pumps
Electro-Hydraulic Proportional Pressure & Flow Control 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. Maximum flow differs to shaft speed.
The value listed above indicates shaft speed of 1800 r/min.
For other shaft speed calculate by the ratio of shaft speed.
■ Pipe Flange Kits
Pipe flange kits are available. When ordering, specify the kit number from the table below.
★ In case of using socket welding flanges, there is a case where the operating pressure should be set lower than the normal because of strength of the
flanges. Therefore, please pay cautious attention to the operating pressure when the socket welding flanges are used.
● Details of the pipe flange kits are shown on page 262.
