Rexroth A4VSO71 Hydraulic Pump 71cc Displacement 280 Bar Pressure

The A4VSO40 and A4VSO71 are models of axial piston variable pumps from the A4VSO series, manufactured by Rexroth. They feature a swashplate design and are specifically engineered for use in open-circuit hydraulic systems. Their flow rate is proportional to both the input drive speed and the displacement volume, allowing for infinite variability of the output flow by adjusting the swashplate angle.

These pumps are recognized for their excellent suction characteristics, which contribute to high operational reliability. They operate at low noise levels and are designed for a long service life. Their modular design offers flexibility for various system integrations. Additional advantages include short response times and the capability for variable speed operation, making them suitable for demanding industrial applications.

• Nominal Pressure: 350 bar
• Peak Pressure: 400 bar
• A4VSO40 Specifics: Displacement of 40, approximate weight of 39 kg, maximum operating speed of 2600 rpm, and a flow rate of 104 L/min.
• A4VSO71 Specifics: Displacement of 71, approximate weight of 53 kg, maximum operating speed of 2200 rpm, and a flow rate of 156 L/min.

A4VSO series pumps, including the A4VSO40 and A4VSO71, are widely used across various industrial sectors. They are commonly found in heavy machinery, industrial hydraulic power units, and other applications requiring robust and efficient variable flow hydraulic power in an open-circuit configuration.
