Performance Curve



- The continuous operation can be made at a point below the curve, however, the continuous operation nearby the rated pressure point may cause a motor breakdown.
   In the case of the continuous operation close to the rated pressure, it is strongly recommended to use the pressure-relief valve. See accessories, page 61.

- The allowable tolerance of the performance value is ± 10%
