Liquidyne® pump shaft seals
Released in 1983, the water-lubricated Liquidyne pump shaft seal was initially intended for heavy-duty dredge pumps. Thanks to its robust design, the seal can handle above-average axial and radial play. It is suitable for pumps that have to deal with severe shocks and vibrations, incorrect alignment and abrasive media. The Liquidyne increases the pump’s lifetime and leads to a longer mean time between maintenance (MTBM) thanks to its robustness. Condition monitoring adds predictability and makes your operation more secure.

- easy to maintain
The Liquidyne has a predictable lifetime due to the condition monitoring function. In addition, the pump shaft seal is also environmentally friendly thanks to the water-lubricated system that saves energy through reduced friction on the shaft.
