Axial piston pump with variable displacement using compact servo piston control.
Clockwise or counterclockwise
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, NFPE, NFPH and MDC control. Vertical input shaft installation is acceptable. 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 non-conformance to these guidelines.
