08:30 REGISTRATION AND REFRESHMENTS
09:00 CHAIR’S OPENING REMARKS
SEAL INNOVATION
09:10 ELECTRO-HYDRAULICALLY CONTROLLED MECHANICAL SEAL: MOTIVATION, SIMULATION, AND PRACTICAL CHALLENGES
Speaker: Professor Richard F. Salant, Georgia Institute of Technology
• Corrects excessive or insufficient leakage through nuclear reactor coolant pump seals
• Coning of non-rotating carbon seal face determines lubricating film thickness and leakage rate
• Coning is varied by varying pressure of fluid in internal cavities of carbon seal face

SEALING CHALLENGES
15:40 DRY GAS SEAL AND SEAL GAS SYSTEM, A PARTNERSHIP FOR RELIABLE OPERATION
Authors: Michael Schiller, Principal Engineer Flowserve Compressor Seal Technology
Detlev Steinmann, Head of Compressor Seal Engineering Worldwide, Flowserve
Most frequent causes of Dry Gas Seal failures
Failure modes and consequences
Possible upgrades on system and seals and procedures to achieve reliable operation
16:10 MECHANICAL SEALS - A PUMP MANUFACTURER’S EXPERIENCES
Dr Chris Radcliffe CEng. MIMechE, Chief Mechanical Engineer, Sulzer Pumps Leeds
Mechanical seal designs are based on certain ideal situations but in practice the real conditions installed in the pump can be less than ideal, leading to operational problems
Shaft dynamic movements can lead to increased seal leakage or even total failure
Transient operating conditions may have thermal and hydraulic influence over the seal’s operation
