Description

Sealing paste for protection of the main bearing of the TBM cutting head. The protection of the main bearing of the cutting head is ensured by the simultaneous injection of a sealing paste resistant to wash-out: HBW NewGeneration and a specific extreme pressure grease. The sealing paste is injected continuously as the machine advances in the labyrinth by flushing downstream of the lip seals. The grease is injected in the inter-seal chambers and leaks towards the labyrinth to mix with the HBW NewGeneration. Product benefits Sealing paste HBW New Generation: Pumpability Resistance to wash-out: water, foam, mud...
