BOSCH Rexroth A1VO Series 10 Axial Piston Variable Displacement Pump
Characteristics ▶ Variable 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 of 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 ▶ Stepless flow variation by adjusting the swashplate angle ▶ Low noise ▶ High power density ▶ Excellent suction characteristics ▶ High flexibility due to interchangeable through drive adapter ▶ For load-sensing-systems in smaller working machines ▶ A1VO Series 10 Sizes A1VO18, A1VO28, A1VO35 ▶ Nominal pressure 250 bar ▶ Maximum pressure 280 bar ▶ Open circuit
▶ A1VO Rexroth piston pumps feature an axial piston swashplate design, ideal for hydrostatic drive applications in open circuits.
▶ The volumetric flow rate varies proportionally with both the driving speed and displacement.
▶ With A1VO Rexroth piston pumps, the volumetric flow rate can be infinitely adjusted by manipulating the swashplate angle.
▶ Offering a range of versatile control devices with diverse pilot and adjustment functions, catering to various critical applications.
▶ Boasting a compact design.
▶ Ensuring high efficiency.
▶ Delivering exceptional power density.
▶ Operating with minimal noise.
