AXIAL PISTON VARIABLE PUMP A4VSO_250_DR_30 SERIES
▶ 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 continuously changed by adjusting
the swashplate.
▶ Excellent suction characteristics
▶ Low noise level
▶ With pre-compression volume for pressure pulsation
reduction
▶ Nominal pressure 380 bar / maximum pressure
420 bar for selected control devices with port plate 36.
▶ Long service life
▶ Modular design
▶ Variable through drive options
▶ Optical swivel angle indicator
▶ Any installation position possible
▶ Suitable for variable-speed drives
▶ HF operation with reduced data possible for HFC
operation, special version available
▶ Robust high-pressure pump
for industrial applications
▶ Size 40 … 1000
▶ Nominal pressure 350 / 380 bar
▶ Maximum pressure 400 / 420 bar
▶ Open circuit
