Technical Specications
General speci cations
Design Axial piston pump of cradle swashplate design with variable displacement
Direction of rotation Clockwise, counterclockwise
Pipe connections
Main pressure ports: ISO split  ange boss
Remaining ports: SAE straight thread O-ring boss
Recommended
installation position
Pump installation position is discretionary, however the recommended control
position is on the top or at the side, with the top position preferred. If the pump
is installed with the control at the bottom,  ushing  ow must be provided
through port M14 located on the EDC, FNR and NFPE control. Vertical input
shaft installation is acceptable. If input shaft is at the top 1 bar case pressure
must be maintained during operation.
The housing must always be  lled with hydraulic  uid.
Recommended mounting for a multiple pump stack is to arrange the highest
power  ow towards the input source.
Consult Sauer-Danfoss for nonconformance to these guidelines.
Auxiliary cavity pressure
Will be inlet pressure with internal charge pump. For reference see operating
parameter on next page. Will be case pressure with external charge supply.
Please verify mating pump shaft seal capability.
