Product Advantages
SY-A7V inclined axis axial variable pump, suitable for open-circuit hydrostatic drives.
Suitable for mobile machinery or industrial applications.
The output flow is proportional to the drive speed and displacement; stepless variation is possible at a constant speed.
Various specifications are available to match each actual drive.
Favorable power-to-weight ratio.
Compact and economical design.
Optimal volumetric efficiency.
Spherical oil distribution between the rotor and the distributor allows for automatic centering during operation, resulting in lower peripheral speed, higher efficiency, and radial load capacity on the drive shaft.
