The terms 'flushing' and 'quench' often seem to be confused or misused when discussing seal support schemes for >slurry pumps. As the concepts of a mechanical seal cartridge and a filled seal cartridge are slightly different, I will discuss them separately and in turn.

What is a slurry?

Find the best position that allows the pump to run as slowly as possible (to reduce wear) but fast enough to prevent solids from settling and clogging the piping.

Many types of pumps are used to pump slurry, but the most common slurry pump is the centrifugal pump. Centrifugal slurry pumps use centrifugal force from a rotating impeller to impinge kinetic energy on the slurry, similar to the way watery liquids pass through a standard centrifugal pump.

The basic mechanical seal flushing programme is very simple. It requires that a clear/clean fluid (usually water) is introduced into the space between the actual seal and the impeller side outlet restriction. The flushing fluid is introduced at a pressure higher than the pumping pressure, thus ensuring positive outflow/flushing of the mechanical seal and a clean operating environment.
