Mechanical seals are leakage control devices. These are found on rotating equipment such as pumps and mixers to prevent the leakage of liquids. They prevent the escape of gases and other liquids into the environment. They seal the point of entry or exit on the rotating shaft to avert the seepage of one high-pressure fluid into the low-pressure fluid. They avoid overall contamination and maintain the efficiency of the machine. Keep on reading this article to learn how an industrial seal works. Four functions of seals ● Provide lubrication to seal faces Mechanical seals reduce friction and improve the efficiency of the machinery. The machine's sealing mode can also be exchanged. For example, you can replace a canned pump with a mechanical seal pump. This replacement will improve the magnetic drive pump, which will boost the machine's overall efficiency. ● Control pressure and temperature in the seal chamber The pressure of the chamber is maintained when
