Feature:
1.Variable pump with axial piston rotary group of swashplate design for hydrostatic drives in open circuit
2.Flow is proportional to the drive speed and displacement.
3.The flow can be infinitely varied by adjusting the swashplate angle.
4.Excellent suction performance
5. Low noise level
6.Long service life
7.Modular design
8. Variable through drive options
9.Visual swivel angle indicator
10.Freely variable installation position
11.Suitable for variable-speed drives
12.HF mode for reduced data possible for HFC mode, special version available
