Proper safety precautions for selecting, installing and maintaining seal systems
Running component wear life and failure are primary cost drivers in the rotating equipment industry.
Bolted flange gasket technology continually evolves with new designs and materials that provide more reliable and durable seals. Plant operators can choose from a wide variety of gasket products that meet the needs of each application; however, selecting the optimal gasket product is only half the battle.
Excessive packing friction adversely impacts pump and valve performance and energy consumption, which translates to an increase in operating and equipment cost. Excessive packing friction may also increase equipment downtime due to packing failure and/or sudden equipment failure.
What are the key steps to cutting packing for optimum performance?
This month's “Sealing Sense” was prepared by FSA Member Ron Frisard and sponsored by the Compression Packing division.
This discussion opens a three-part series covering mechanical seal piping plans that provide guidelines for various seal arrangements, fluids and control equipment to help you determine what support system requirements will maximize the performance reliability of your application.

Proper safety precautions for selecting, installing and maintaining seal systems
Modular seal designs do not lessen the need for proper selection of the core seal whether it is a single or dual, unbalanced or dual balanced, ID or OD pressurized, pusher or non-pusher, rotating head or seat and so on.
Two imperatives for many of today's industrial plants are to reduce the cost of operations through the enhancement of rotating equipment reliability and enhanced energy efficiency of pumping systems.
Mechanical seal failures are usually the symptom and not the cause of maintenance problems, many of which are related to static misalignment. In operation, other forces such as radial loads, impeller balance and cavitation also affect seal alignment.

Since the original publication of this draft standard in the January 2008 issue of Pumps & Systems, I have received feedback, encouragement, numerous questions and criticism. The draft listed three basic levels of repair.
The McGraw-Hill scientific dictionary [5] states that a volute is "a spiral casing for a centrifugal pump... designed so that speed will be converted to pressure."
