External Gear Pumps Multiple – PGE104
Gear pumps can be combined to double or triple units (for larger units please contact HYDAC).
Generally, the specifications for the single pumps apply, but the following notes should be observed:
- Possible combinations are pumps of same size or units in decreasing order of the pump size
- It is recommended to position the pump with the largest displacement on the drive side
- The max. speed of the multiple pump unit is determined by the pump rated with the lowest speed
- The maximum pressure of the unit or the following stages is restricted by the admissible torque of the drive shaft and the through drives.
