Axial piston pump of cradle swashplate design with variable displacement,
connections:Main pressure ports: ISO split flange 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, 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.
Details regarding the choice of hydraulic fluid
The correct choice of hydraulic fluid requires knowledge of the operating temperature in relation to the ambient temperature: in a closed circuit the circuit temperature. The hydraulic fluid should be chosen so that the operating viscosity in the operating temperature range is within the optimum range - the shaded area of the selection diagram. the higher viscosity class be selected in each case. Example: At an ambient temperature of X °C an operating temperature of 60 °C is set. In the optimum operating viscosity range (shaded area) this corresponds to the viscosity classes VG 46 or VG 68; to be selected: VG 68. Please note: The case drain temperature, which is affected by pressure and speed, is always higher than the circuit temperature. At no point in the system may the temperature be higher than 110 °C. If the above conditions cannot be maintained due to extreme operating parameters, please consult us.
