(Theorial values, without considering n_hm and n_v; approximate values). Peak operations must not excede 1% of every minute. A simultaneous maximum pressure and maximum speed not recommended.

1. Maximum and minimum displacement can be changed with continuity. When ordering state Vg_max and Vg_min required.
2. Determination of displacement. To determine the relationship beetween Vgmax and n_max use the right side chart. Motor maximum admissible speed is n_{max lim.}
3. Approximate values.
4. Maximum value at 250 bar [3625 psi] with mineral oil at 45ºC [113ºC] and 35 cSt of viscosity.
