Under the condition of tank pressurization or using the optional built-in filling pump (impeller), the pump operates in automatic start-up oil injection state.

Provides various control options to meet the requirements of various applications.

The power control option is externally adjustable, even while the pump is running.

Through-shaft drive is suitable for integrated gear pumps and axial piston pumps, i.e., 100% through-shaft drive.

The output flow rate is proportional to the drive speed and can be infinitely varied between 9V _max and qv _min =0.

1. The values apply to the absolute pressure (p _abs ) of 1 bar at the suction port S and mineral hydraulic fluid;

2. The values apply to the absolute pressure (p _abs ) of at least 0.8 bar at the suction port S and mineral hydraulic fluid;

3. The values apply to V _g ≤V _{g max} or the inlet pressure p at the suction port S _abs increase.
