HW – proportional hydraulic control, mechanical servo

EP – proportional electric control

HT – hydraulic control, direct controlled

ET – electric control, direct controlled

DA – control valve, fixed setting

Features
▶ Variable double pump with two axial piston rotary
groups of swashplate design for hydrostatic drives in a
closed circuit
▶ The flow is proportional to the drive speed and displacement.
▶ The flow can be infinitely varied by adjusting the swashplate angle.
▶ Flow direction changes smoothly when the swashplate
is moved through the neutral position.
▶ Only one shared port for case drain fluid for both circuits
▶ Compact design for tight installation conditions
