A device used to remove solid particles from liquid or gas.

These filters are often installed in a discharge recirculation line located between the discharge side of the pump and the pump’s stuffing box to prevent solids from clogging up the mechanical seal.

The problem is the filters will clog up with solids, resulting in a premature seal failure.

Cyclone separators are another common choice, but they almost always produce similar poor results.
