Short CourseThis short course is designed for all personnel that interacts with mechanical seals such as engineers, users, installers, purchasers, reliability engineers, and other industrial plant functions. It starts with basic operating and then goes into greater details of all aspects relating to the use and obtaining maximum operating life for dynamic shaft sealing

Session 1
Presenter
• Steven Bullen - A.W. Chesterton Co.
– Steven Bullen completed his formal education as a Mechanical 
Engineering Design Technician in 2001 whilst working in his first 
employment designing, manufacturing and specifying sealing devices 
for rotating equipment. Steven has worked in the Sealing industry for 
over 18 years holding various positions in Design & Test Engineering, 
Production Engineering, Application Engineering, Sales Management 
and Product Management. He has supported a myriad of customers & 
industries. Before leaving Europe he was the Mechanical Seals Divisional 
Chairman for the European Sealing Association. He is currently 
Chesterton’s Global Product Manager – Mechanical Seals.
Effective forces in a Mechanical Seal
• Axial and radial forces 
• Closing and opening forces
• Hydro static and hydrodynamic forces
Dual Gas Seals
Materials of Construction
Secondary Seals
Presenter
Brian Kalfrin – John Crane 
Brian Kalfrin is a Regional Engineer for John Crane in Pasadena, Texas. He has over 17 
years of experience with mechanical seals and related equipment. Mr. Kalfrin is 
responsible for troubleshooting and diagnostic failure analysis and root cause analysis 
for seal and sealing system applications. He is involved in evaluating new seal 
applications as well as optimizing existing sealing solutions to meet reliability and 
emission requirements. Mr. Kalfrin has been actively involved with training internal John 
Crane engineers as well as external customers and seal users.
Mr. Kalfrin received his BS degree in Mechanical Engineering from Drexel University. He is 
a member of the Texas A&M Pump Symposium Advisory Committee.

Presenter
Michael Huebner – Flowserve Corporation
Mr. Huebner is a Principle Engineer at Flowserve Corporation in Deer Park, Texas. Mr. Huebner 
has been involved with the design and application of centrifugal pumps, mechanical seals, 
and fluid handling equipment for over 30 years. At Flowserve, he has been responsible with 
new product development, research, product testing, field service, and technical support. He 
has published numerous articles in publications and journals including in the Pump Handbook 
and the Encyclopedia of Tribology. He has held positions both in the U.S. and Europe.
Mr. Huebner has taught extensively around the world on topics of mechanical seals, pump 
operations, failure analysis, and API 682. He continues to support training internally, at end 
users, and at major symposiums and conferences. Mr. Huebner received his BA in Engineering 
Technology from Texas A&M University. He is a member of the API 682 Task Force on 
mechanical seals and the ASME B73 Committee for centrifugal pumps. He is on the Texas 
A&M Pumps Users Symposium Advisory Committee and is a member of ASME.

Energy Consumption of Sealing Systems 
and Life Cycle Costs
Presenter
Henri Azibert – Fluid Sealing Association
• Henri V. Azibert started his career as counsel for the State Rating Bureau for the 
Division of Insurance for the Commonwealth of Massachusetts.  He then joined the 
A.W. Chesterton Company where he had responsibility for all the mechanical seal 
and mechanical packing engineering staff and product lines.  For the past four 
years he has been retained as the Technical Director for the Fluid Sealing 
Association.  
• He received his Baccalauréat from Lycée Louis Le Grand, a B.A. in Political Science 
from the University of Massachusetts, a Jurisprudence Doctor from Boston College, 
and a Masters degree in Mechanical engineering from Northeastern University. 
• Mr. Azibert was granted over thirty patents on mechanical seal designs and 
improvements. He is a member of the API 682 and 3A Mechanical Seal Standard 
Task forces, has been a member of the Texas A&M Pump Symposium Advisory 
Board; he has chaired several committees for the Fluid Sealing Association.
Session 4
• Seal chamber design
– Impact on seal performance
• Seal Installation
– Component seals
– Cartridge seals
– Split seals 
• Energy Consumption of Sealing Systems
– Frictional wear
– Thermal losses
• Life Cycle Costs
– Acquisition costs are a very small fraction of the life cycle costs
