XLF-A8VO Axial Piston Fixed Pump Features
- Fixed pump with axial tapered piston rotary group ofbent-axis design, for hydrostatic drives in an open circuit
- For use in mobile and stationary applications- The flow is proportional to the drive speed and displacement
- The drive shaft bearings are designed for the bearing servicelife requirements usually encountered in these areas
- High power density
- Small dimensions
- High total efficiency
- Economical design
- One-piece tapered piston with piston rings for sealing
