Axial piston variable pump
A1VO Series 10
Features
▶ Variable displacement pump with axial piston rotary
group of swashplate design for hydrostatic drives
in open circuit
▶ Flow is proportional to the drive speed and
displacement.
▶ The flow can be infinitely varied by controlling the
swashplate angle.
▶ Significant fuel savings up to 15% compared to fixed
systems
▶ Optimized efficiency, though same power at less
fuel consumption
▶ Increased service life compared to gear pumps
▶ Compact design by integrated controller
▶ A wide range of highly adaptable control devices for all
important applications
▶ Low noise
▶ High power density
▶ Excellent suction characteristics
▶ High flexibility through interchangeable through
drive adapters
▶ For load-sensing systems in smaller working machines
▶ Sizes 18, 28, 35
▶ Nominal pressure 250 bar
▶ Maximum pressure 280 bar
▶ Open circuit
