Mechanical seal

Mechanical seals are very effective devices. pump must accommodate a rotating shaft while mechanically retaining the liquid or gas contained in the "wet end" of the pump. Mechanical seals consist mainly of the surface of a rotary seal with a driving mechanism that rotates at the same speed as the pump shaft, stationary seal surfaces paired with rotary and maintained using glands or in some models of pumps the integral filling box, tension assembly (functioning spring or bellows metal) keeps the rotary position firmly on the stationary face preventing, excluding, and containing contamination and leakage, both when the pump is inoperative and when the pump shaft rotates. Static sealing gaskets, elastomeric orings or bellows are strategically located to complete the seal assembly.
