1: Do not drive motor with max. torque/max. pressure in more than 6 seconds.
2: Recommended hydraulic oil: ISO-VG32 or same class.
3: Max. input pressure must be less than 21MPa (3045.80 spi).
4: Max.permissible back pressure is 7MPa (1015.27 Spi), but in the case of operating with more than 1.8MPa (261.07spi), drain piping is required be implemented to protect oil seal.
5: Displacement capacity per one rotation is 4 times larger than above theoretical displacement.
6: ΔP means differential pressure.
7: Unit weight of 4 bolt flange model is 2.1kg (4.63lbs) heavier than above weight.
8: Gear oil is filled by NOP® factory before shipping out.
