Product Description
Technical data
Series 33.
Sizes NG71, 90.
Nominal pressure 400 bar.
Maximum pressure 450 bar.
Closed circuit.
For the drum drive in mobile concrete mixers.
Features
--Variable axial piston pump of swashplate design for hydrostatic drives in closed circuit
--The flow is proportional to the drive speed and displacement.
--The flow increases as the angle of the swashplate is adjusted from zero to its maximum value.
--Flow direction changes smoothly when the swashplate is moved through the neutral position.
--Two pressure-relief valves are provided 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 pump and control pressure supply.
--The maximum boost pressure is limited by a built-in boost pressure-relief valve.
