Features
● Variable pump with axial piston rotary group in swashplate design for hydrostatic drives in open circuit.
● The flow can be infinitely varied by adjusting the swashplate.
● Auto suck or by charge pump.
●Comprehensive control device have very high adaptability to achieve various control and adjustment function.
● The through drive is suitable for adding gear pumps and axial piston pumps up to the same size, i.e., 100% through drive.
● Compact design, favorable power/weight ratio.
● High efficiency.
● Low noise level.
