Pumps handle harsh environments

The optimised drive of the A10VSO 32 series permits higher rotational speeds and up to 3% greater efficiency than previous models.

Increased efficiency, lower noise generation and improved controllers are the main features of Rexroth's 32 series of the A10VSO variable axial piston pumps.

Designed for use in the upper medium-duty range, these variable displacement pumps are suitable for use in harsh working environments.

Typical applications include plastics processing machines, machine tools and power units.

Available initially in nominal sizes of 71, 100 and 140 (with sizes 28, 45 and 180 to follow) and with a nominal maximum pressure of 280bar and a 350bar peak pressure, the optimised drive of the A10VSO 32 series permits higher rotational speeds and up to 3% greater efficiency than previous models.

Improvements in the housing design have helped to reduce noise levels by up to 3dB.

Rexroth design engineers have also succeeded in achieving greater resistance to suction-pressure dips and housing-pressure peaks.

Rexroth can supply most of the nominal sizes offered with either a two or a four-hole flange.

Another innovative feature of the pump is the universal through drive, allowing the flexible connection of a range of other pumps using a corresponding flange kit.

The 32 series of the A10VSO also offers a range of controllers and adjustments that further increase flexibility.
