- Series 33
Sizes NG71, 90
Nominal pressure 400 bar
Peak pressure 450 bar
Closed circuit
For the drum drive in mobile concrete mixers
Features
- Variable axial piston pump of swashplate design for hydro-static closed circuit transmission
- Flow is proportional to drive speed and displacement and is infinitely variable
- Flow increases with the swivel angle of the swashplate from 0 to its maximum value
- Flow direction changes smoothly when the swashplate ismoved 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 to replenish leakage and provide control oil.
- The maximum boost pressure is limited by a built-in boost-pressure-relief valve
