We specialize in single spring mechanical pump shaft seals for rotary / centrifugal pump applications. It's easy to replace your pump seals if you know what they are. If you do not have a pump seal number such as XX-100, you can identify what kind of seal you have, by comparing your mechanical seal components to the drawings below.
The "working length" of the seal is critical to your seal application. To identify the working length, measure your mechanical seal end to end, this is your seals "total length". From this you must subtract 50% of the uncompressed spring length. This is your mechanical seals working length.
To make sure your pump seals stationary seat fits, it's a good idea to provide the inside dimension of the bore it will be fitting into. The outside dimension of your seals stationary seat is helpful but more difficult to obtain an accurate measurement. Most pump seal stationary seats have a rubber cup or o-ring that must be compressed when it is installed.
