The popular A8vo Series Hydraulic piston Pump Rexroth Brand

Hydraulic piston double pump A8VO55, A8VO80, A8VO107, A8VO140, A8VO200

Description

Open circuit
Series 61 / 63
Control devices: LAOH2, LAOK, LAOKS, LAOKH1, LAOKH2, LAOKH3, LA1H2, LA1S, LA1K, LA1KS, EP, LA1KH1, etc.
Nominal pressure 350 bars. Peak pressure 400 bars

- Variable double pump A8VO with two axial tapered piston rotary groups of bent-axis design for hydrostatic drives in open circuits
- The flow is proportional to the input speed and to the displacement, and is infinitely variable from qV max to qV min = 0
- The pump is suitable for direct mounting on the flywheel case in diesel engines
- One common suction port for auxiliary pump and both circuits
- A wide range of control instruments is available for different control and regulating functions
- Individual power controller
- Integrated auxiliary pump with pressure-relief valve, optionally with additional pressure-reduction valve
- Power take-off for mounting axial piston and gear pumps
- Excellent power to weight ratio
- Long service life
