GP
Design features and properties
- injector pump of “back-to-back” arrangement
- version with NPSH impeller
- axial thrust compensation by means of “back-to-back” arrangement of impellers
- bearings: antifriction bearings or slide bearings
- very stable rotor dynamics also in case of large number of stages
- central slide bearing ensures very smooth running and low vibration values
- very small load on axial bearings due to back-to-back arrangement, long service life
