Note:

1. When pressure of pumps exceeds 16MPa, with displacement of "4""6""8", speeds should be more than 1450r/min.

2. Reduce the negative pressure of the inlet when the single pumps or double pumps with large displacement at high speed.

3. In use of synthetic hydraulic fluids and water containing hydraulic fluids, limit the max speed at 1200r/min.

4. Speed at 1000r/min is suggested on occasions with lower noise strictly required.

5. Noisiness is available in working conditions of 14MPa and 1200r/min.

6. Input power is available in working conditions of 16MPa and 1500r/min.
