Proper safety precautions for selecting, installing and maintaining seal systems
his is the second of a four-part Sealing Sense series that provides guidance on best practices to minimize the size of the sealing system energy footprint.
The ultimate dream of a facility manager at any manufacturing plant is to install a piece of equipment and then—except for instances of planned maintenance or for a performance review—forget about it.
You ultimately choose whether you send your used seals to the Seal OEM or to a non-OEM repair shop. Price and delivery obviously enter into the decision process. The trade-off, however, could turn out to be lower seal reliability and higher safety and environmental risk.
The introduction of the new series of standards for active pharmaceutical ingredients contributes to the pharmaceutical industry's efforts to improve the economy and efficiency of the entire manufacturing process and maintain the strict requirements of hygienic design and cleanability throughout their production process.
Although many of the energy costs of a shut-down can be difficult to quantify, they are numerous and substantial. Maintaining a process stream in operation increases its overall efficiency, while failures decrease it.

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.
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.
Running component wear life and failure are primary cost drivers in the rotating equipment industry.

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."
