The Liquidyne® pump shaft seals are the alternative to industrial gland packing and mechanical seals. The water-lubricated Liquidyne is the next step towards Industry 4.0 and has a predictable lifetime due to the condition monitoring function. Our industrial sealing solutions are mainly applied to (cooling) water pumps, process pumps, vertical pumps and axial pumps. 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. How? Come and visit our booth (G17) and we will be happy to tell you more about it!

Lubo International levert kant & klare bevestigingsmaterialen voorzien van droge smering. Lubo bouten zijn 100% duurzaam en inzetbaar in extreme omstandigheden. Temperaturen van -120 °C tot + 1400 °C, maar ook zout water en zand vormen geen bedreiging voor de droge lubrication op Lubo Fasteners. De Lubo bout hoeft niet gesmeerd te worden met vervuilende montagepasta. Daardoor worden kosten bespaard. Onze droge smering loopt voorop wat betreft milieuvriendelijkheid en is daarom FDA & EC 1935/2004 compliant en PFAS-vrij. Petrochemie, water & infrastructuur zijn hier ontzettend bij gebaat. Alle Lubo Fasteners vervaardigen wij in ons productiebedrijf in Zeeland. Met onze productielijn brengen wij d.m.v. een geavanceerd cameraproces een droge smering aan op de buitendraad van verschillende soorten bouten, draadeinden of studs. Wij kunnen hierdoor een breed assortiment A2 en A4 bouten uit voorraad leveren. www.lubointernational.com
