Hydraulic Products: Axial-Piston Pump
The redesigned A4VG variable pump is for closed-circuit applications.
Nominal pressure rating has
increased by 700 psi over previous
versions, to 6,500 psi, and it has
been adapted to counteract lower
diesel-engine speeds and lower input
flow rates.
The housing on
the swashplatedesign
pump
accepts sensors for monitoring swivel
angle, pressure, and rotational speed.
A bowl-shaped design avoids highpressure
transitions at sealing points
and relocates the high-pressure
ports to optimize hydraulic
line routing. All connections
use O-ring seals to ensure leaktight
threads. The A4VG combined
with Series 71 A6VM axial-piston
variable motors provide high-power
density for hydrostatic travel drives.
