Dredgers, according Midé Marine, need to be in compliance with Reclamation Safety & Health Standards, and will at times require a bulkhead shaft seal. 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 – thanks to the manufacturer's 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 design is ideal for sealing around pump shafts."

The bulkhead shaft seals are ABS, DNV, BV and Lloyds certified, add the company.
