Durable pumping stations

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. 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. This makes the Liquidyne a durable solution for pumping stations.


The Liquidyne pump shaft seals are the alternative to industrial gland packing and mechanical seals. Discover the differences via our blogs below:
