- Maximum safety due to double casing design. Pipework connections remain undisturbed during disassembly of cartridge
- Vertical back-to-back barrel type pump
GVG diffuser style barrel pump
Maximum safety pump used in nuclear power plants
The GVG is a pump especially designed to charge the reactor coolant in a nuclear power plant. The pump is designed to produce high pressure by small capacity with direct drive.
- Reactor cooling in nuclear power stations
- Control rod drive pump
Main design features
- Vertical barrel pump with high number of stages
- Back-to-back desgin of impeller arrangement to reduce axial load
- High alloyed barrel material avoids corrosion
- Double mechanical seal with external seal water cooler
- Product-lubricated radial bearings
- Axial thrust anti-friction bearing for residual axial load
