Dredgers, to be in compliance with Reclamation Safety & Health Standards, will at times require a bulkhead shaft seal.
Midé Marine’s Omni Seals have proven to be a viable shaft sealing solution, as they will not make contact with the pump shaft unless there is a flooding event. This is due to Midé Marine’s seals’ innovative HydroActive™ (water activated) design – which uses flood water to activate and engage the seals.
The normal operational condition for Midé Marine’s seals provides a 3mm running gap between the shaft and lip seal, and a 10mm gap before the shaft will come in contact with any hard component. Performance is never compromised, as this design feature can eliminate wear on both shaft and seal – dramatically reducing wear and maintenance, and increasing long term safety and savings.
Dan Collins, Mide Marine’s Director of Sales , said: “ We are confident the Dredging community can benefit from our non-contacting shaft seals, as their innovative design is ideal for sealing around pump shafts. ”
Mide Marine’s bulkhead shaft seals are ABS, DNV, BV and Lloyds certified.
Self-activating, non-Contacting HydroActive Design
The core technology behind Midé Marine’s innovative bulkhead seals is its hydrogel embedded foam. Developed over the past decade, this foam enables the seal to not contact the rotating shaft during the majority of its life.
However, when flooding event is occurring, the hydrogel embedded foam uses the water from the flooding to swell and provide a robust and reliable seal against the shaft.
