Sealing devices account for only a small fraction of the energy consumed by pumps; the scope for energy conservation at first appears limited. However, the paper details areas where significant energy conservation has been achieved by elegant sealing practices. Process industries have enjoyed savings in energy associated with seal cooling water circulation. A correlation between effluent reduction and carbon emission is postulated. Technology can provide the process industries with significant efficiency improvement in seal cooling. Case studies are reviewed from several industry sectors. API standards endorse many of these techniques as best practice. The mechanical seal industry contribution is key in assisting pump users to play their part in reducing adverse climate change.
