Mechanical seals are devices that help join systems or mechanisms together by preventing leakage, which are found on rotating equipment such as pumps and mixers to prevent the spillage of liquids and gases from escaping into the environment. This Seal consists of two parts, one is stationary part and the other rotates against it to achieve a seal. The effectiveness of a seal is dependent on adhesion in the case of sealants and compression in the case of gaskets. The design, arrangement and materials of construction are determined by the pressure, temperature, speed of rotation and product media.
