Slurry Pump

Quenching is defined as the introduction of a neutral fluid (usually water or steam) into the atmospheric side of the seal to prevent the formation of solids that may interfere with movement or be used for other purposes.

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 we mean by slurry is basically a liquid containing solid particles. When you want to pump this slurry, there are different requirements than when pumping only dirty water. A waste water pump cannot handle the solid particles of a slurry. This is where slurry pumps come in handy. , Slurry pumps, are heavy duty and robust versions of centrifugal pumps, capable of handling tough and abrasive tasks.

To reduce component wear, most centrifugal slurry pumps run at fairly low speeds - typically less than 1200 rpm. Find the optimum position that allows the pump to run as slowly as possible but fast enough to prevent solids from settling out of the slurry deposit and clogging the lines.
