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.
Whoever coined the phrase "Don't sweat the small stuff" was likely not an engineer. Everything engineers do is ultimately defined by the success of "the small stuff" that comprises the larger design projects.
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.
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.

All three API Plan 53 versions are intended to isolate the pumped product from the atmosphere and create a favorable artificial environment for the mechanical seal. Which of the three is optimal will depend on the specifics of the application. The choices of barrier fluid and maintenance capabilities are fundamentally important design considerations. Differences in the three include cooling and pressure capability as well
A discussion of current compression packing technology will help set the stage for an example of how this can be accomplished. Compression packing is still widely used to seal rotating equipment such as pumps.
New packings, as well as application methods, are continuously engineered to meet industry's increasing demands for performance and environmental compliance. Packings, fibers and lubricants will continue evolving, and proper packing selection will be an increasingly important task.
Avoiding seal leakage or failure is a complex task for pump designers and one that must be taken seriously in difficult economic times when reducing downtime is critical. New developments in elastomer materials and seal design techniques mean that pump engineers can avoid seal leakage and ensure optimum performance in demanding operating environments involving high and low pressures and temperatures.
Sulfur leakage, causing housekeeping and environmental issues in a refinery, was stopped with an innovative seal configuration.

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."
