- Nominal pressure 350 bar.

- Maximum pressure 400 bar.

- The pump A7VO was designed for operation in open loop circuits

 

The A7VO is a variable displacement pump with a bent tapered axial piston transmission for open-circuit hydrostatic drives. Flow is proportional to drive speed and displacement. Flow can be continuously adjusted by adjusting bent axis.

For mobile and stationary hydraulics applications, the Bosch Rexroth A7VO features an axial tapered piston and a unique bent axis design.

- Variable pump with axial tapered piston rotary group of bent axis design, for hydrostatic drives in open circuit;

- For use in mobile and stationary applications;

- The flow is proportional to the drive speed and displacement;

- The flow can be infinitely varied by adjusting the bent axis;

- Wide selection of control devices;

- Compact, robust pump with long service life;
