H1P 147/165 Technical Data

© Danfoss | May 2017
Axial piston pump of cradle swashplate design with variable displacement
Clockwise, Counterclockwise
Main pressure ports: ISO split flange boss
Remaining ports: SAE straight thread O-ring boss
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, flushing flow 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 filled with hydraulic fluid.
Recommended mounting for a multiple pump stack is to arrange the highest power flow towards the input source.
Consult Danfoss for nonconformance to these guidelines.
Will be inlet pressure with internal charge pump. For reference see
Will be case pressure with external charge supply. Please verify mating pump shaft seal capability.
