When operating the pump exceeding the rated pressure, operating conditions are restricted. Refer to page 6 for the details.. Maximum flow differs to shaft speed. The value listed above indicates shaft speed of 8 r/min. For other shaft speed calculate by the ratio of shaft speed.. To secure the required minimum pressure, special sequence valves are available, to be directly installed at the discharge port of the pump. Consult Yuken for details. No.8. (.).7 (.). (.).7 (.)
