3. Structural & Performance Features
-
Adopts swashplate design with axial piston rotary group, suitable for hydrostatic drives in open circuits.
-
Flow is proportional to drive speed and displacement, and can be continuously and steplessly adjusted by changing the swashplate angle.
-
Low operating noise, long service life, and excellent suction characteristics, effectively reducing cavitation risks.
-
The drive shaft can bear axial and radial loads, with a favorable power/weight ratio.
-
Equipped with pressure/flow control (DFR1) with short response time, ensuring precise control of system pressure and flow.
-
No internal drain line and no connector for solenoids (standard configuration).
-
Widely used in engineering machinery, metallurgy, mining, ships and other industrial fields.
