SHIM SEAL

A mechanical seal is a device that helps join systems or mechanisms together by preventing leakage (e.g. in a pump system), maintaining temperature, containing pressure, or excluding contamination. The effectiveness of a seal is dependent on adhesion in the case of sealants and compression in the case of gaskets or o-rings.

A shim is a washer or thin strip of material used to align parts, make them fit, or reduce wear. Shims may also be used as spacers to fill gaps between parts subject to wear. On machinery installations (pumps, motors, etc.) the recommended practice requires new shims to be placed under every supporting foot. This guarantees flexibility for adjustments, like a slight raising or lowering of a motor, when parts of the machinery need to be replaced and aligned properly.
