Pump Shaft Seals
We specialize in single spring mechanical pump shaft seals for
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 PS-100, you can identify what kind of
seal you have, by comparing your mechanical seal components to the pictures.
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 rubber cups or o-rings that must be compressed when they are installed.
