H1P general specifications

Axial piston pump of cradle swashplate design with variable displacement
Design
Clockwise, counterclockwise
Direction of
rotation
Main pressure ports: ISO split flange boss
Pipe connections
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
Recommended
position preferred. If the pump is installed with the control at the bottom, flushing flow must be provided through port M14
installation
located on the EDC, FNR and NFPE control. Vertical input shaft installation is acceptable. If input shaft is at the top 1 bar case
position
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 operating parameter on next page. Will be case pressure with
Auxiliary cavity
external charge supply. Please verify mating pump shaft seal capability.
