17.3.3 Calculating the torque on the secondary shafts
(coupling sleeves)
For the maximum permitted torque on the respective secondary shaft, see chapter
17.4.
Fig. 17.2: Calculating the torque for secondary shafts
Torque on the secondary shaft of the B- or C-pump:
If the calculations show that the permitted values have been exceeded, check
whether the maximum possible pressures occur at the same time.
If simultaneous loads cannot be avoided, there are two options:
• reduce the pressures until the permitted torque values are not exceeded,
• replace an overloaded pump stage with one that can take higher pressures.
