GP
Range of application
- water injection
- refineries
- pumping of brine
- oil and gas industry
- generation of pressure in industrial areas
Operating data, Characteristic Curves
- Q= 600 m³/h
- H= 2500 m
- P= 250 bar
- T= +180 °C
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
Materials
- grey cast iron
- ductile cast iron, ADI materials
- cast steel
- 12 % chromium steel
- austenitic steel
- special alloys
Bearing configurations
- Standard Version
Radial bearings: antifriction bearings

Wear-resistant Design
- Injector pumps of wear-resistant design for especially abrasive liquids, liquids containing solids
- Even on wear of clearance spaces the remaining axial thrust is changing just slightly, bearing load of axial bearing remains equally low.
