Is this a mechanical seal application? 15-7

You have three opportunities to do a mechanical seal application:

First we will look at the piece of equipment you will be sealing. Sometimes mechanical seal life is directly related to the type of hardware you are sealing:

Constant running equipment is easier to seal than intermittent equipment.

Pumps, located inside buildings, are not subject to the changes in weather that affect some liquids you will be sealing.

The driver you choose can affect the life of the mechanical seal:

Does the equipment you will be sealing, fall into the following categories? If so the seal has a good chance of surviving with an environmental control. If your application falls outside these categories you might consider a special seal design:

A temperature range of -40 to 400°F (-40 to 200° C)?

A pressure range of one Torr to 400 psi (one Torr to 7 bar) in the stuffing box?

Electric motor speeds or slower?

Always consider cleaners, steam and solvents that might circulate in the lines after or between batches. Whatever seal you choose must seal these fluids also.

If you are troubleshooting a seal failure and think you might have an application problem, consider the following:
