External Gear Pumps Multiple – PGE104
It’s possible to combine gear pumps to double or triple units (for larger units please contact HYDAC).
Generally, the specifications for the single pumps apply, but we should observe the following notes:
- Possible combinations are pumps of same size or units in decreasing order of the pump size
- It’s best to position the pump with the largest displacement on the drive side
- The determination of the max. speed of the multiple pump unit happens with the pump rated with the lowest speed
- There is restriction about the maximum pressure of the unit or the following stages by the admissible torque of the drive shaft and the through drives.
See our data-sheet for more details.
