This two-day workshop on mechanical seals will provide participants with knowledge and skills in seal selection, maintenance, troubleshooting and maximizing seal life. The workshop covers seal fundamentals, design, materials, failure analysis, environmental factors and repair. Participants will learn how to classify seals, understand repair methods, troubleshoot issues, and implement best practices to extend seal performance and reduce costs through seal life optimization.

At the end of this workshop participants will be able to: • Demonstrate a sound understanding of the fundamentals of seal selection • Understand environmental considerations related to seals • See how the experts repair and rebuild seals for outstanding performance • Troubleshoot seals • Maximise mechanical seal life • Classify various seals, including special seal types • Explain considerations related to the materials used in seal construction Practical MECHANICAL SEALS - SELECTION, MAINTENANCE and TROUBLESHOOTING YOU WILL LEARN HOW TO: 7.37
DAY TWO ENVIRONMENTAL CONSIDERATIONS AND CONTROL • Abrasives, heat, dry operation • Flushing, recirculation, quenching • Convection, cooling, jacketing • Buffer and barrier fluid • Dead end lubrication, grease packing, circulating face lubrication • API 610 environmental control schemes AUXILIARY EQUIPMENT • Cyclone separators • Pressurization units • Air-coolers and heat exchangers • Rotameters and flow controllers • Leakage detectors • Filters and strainers SEAL HANDLING AND INSTALLATION • General considerations • Seat squareness SEAL FAILURES • Factors influencing seal life • Factors affecting seal performance • Seal malfunction and probable causes • Friction and wear • Adhesion, abrasion • Corrosion and surface fatigue SEAL SELECTION AND STANDARDS • Seal selection guides • Standards-ISO, British, DIN, ASME TROUBLESHOOTING FAILED SEALS • At the pumping site • At the equipment teardown • Discoloration, chipping, cracking, rubbing, elastomer swelling, stickiness, hardness - what do these mean? HOW TO MAXIMISE MECHANICAL SEAL LIFE • Preparing the pump - mechanically, hydraulically • Controlling temperature in the stuffing box • Controlling pressure in the stuffing box • What seal to choose? • What face combination and elastomer? SUMMARY, OPEN FORUM & CLOSING DAY ONE FUNDAMENTALS AND PRINCIPLES • Definition of zero leakage • Mechanics of sealing • Purpose of sealing • Basics regarding speed and pressure • Basic seal requirements • Seal friction • Wear and seal life • Texture • Seal balance criterion - balance ratio, pressure distribution • Seal applications • Operating capabilities, advantages and limitations SEAL DESIGN AND CLASSIFICATION • Identifying seal components and their function • Primary sealing components - seal head, seal seat, springs for face loading, metal bellows • Secondary sealing components - elastomeric O-rings, V-rings, U-cup rings, wedge rings • Inside and outside seals • General arrangement modes - Single: cartridge, component, split, stationary - Duplex: tandem, back-to-back • Static and dynamic seals • Rotating and stationary seal heads • Sealing face conditions • Seal pre-loading SPECIAL SEAL TYPES • Bellows • Bushing, labyrinth, diaphragm • Gas, motion, slurry • Carbon seals • Liquid ring and liquid barrier seals • Inflatable, ferrofluidic • Positive action type • Self-adhesive compression seals MATERIALS OF SEAL CONSTRUCTION • General considerations • Properties of elastomers • Elastomeric materials • Plastic polymers • Cemented carbides • Miscellaneous sealing materials • Material compatibility SEALS FOR SPECIFIC/SPECIAL APPLICATIONS • Hydraulic • Pneumatic • High temperature • Large diameter THE PROGRAM Whether you consider yourself as amateur or knowledgeable, practical or theoretical, you will find this two-day Mechanical Seal workshop is jam-packed with useful, easy to apply information. Faced with the bewildering task of selecting the correct seal type and materials of construction for a given application, it's no wonder many end users leave the job to others. After attending this course, you will gain the knowledge and confidence, to select correct seal types, analyse failed seals, determine the cause/s of failure and propose practical, remedial action. Learn how, with simple modifications, you can extend seal life and reduce or eliminate causes of premature seal failure. The course commences with a solid review of the fundamentals, basic principles and looks at seal classification and design. Special seal types are examined and the materials used to construct seals ranging from elastomeric materials to cemented carbides are examined. Day One is concluded with an examination of seals for specific applications. The Second day focuses on environmental considerations of seals, seal handling and installation, seal failure and troubleshooting seals. The course is rounded off with an examination of the all-important topic of how to maximise seal life and thus derive measurable financial savings from your knowledge of seals. Through this course, you will understand the basic needs of mechanical seals, and by applying what you learn, you will positively impact on the real costs of seal ownership to your company.
