Features

 Variable axial piston pump of swashplate design for hydrostatic closed circuit transmission

Flow is proportional to drive speed and displacement and is infinitely variable

Output flow increases with the swivel angle of the swashplate from 0 to its maximum value

Flow direction changes smoothly when the swashplate is moved through the neutral position

A wide range of highly adaptable control devices is available for different control and regulating functions

The pump is equipped with two pressure-relief valves on the high pressure ports to protect the hydrostatic transmission (pump and motor) from overload

The high-pressure relief valves also function as boost valves

The integrated boost pump acts as a feed and control oil pump

The maximum boost pressure is limited by a built-in boost pressure relief valve

Application

Piston pumps are widely used in high-pressure, high-flow, high-power systems and where the flow needs to be regulated, such as mobile and construction equipment, engineering vehicles, heavy-duty planers, metal forming and stamping, machine tools, hydraulic presses, oilfield equipment, mining and metallurgical machinery, marine and other hydraulic systems.

The A10VO and A10VSO are variable pumps with axial piston rotary group in swashplate design for hydrostatic drive in an open circuit. Flow is proportional to drive speed and displacement. The flow can be steplessly changed by controlling the cradle. For axial piston units with swashplate design, the pistons are arranged axially relative to the drive shaft.
