Mostly as name implies, mechanical seal's function is to stop any leak from pump or similar equipment while pumping water or fluid. Seal has two parts, one fixed on rotor while other part on casing. Both parts are faces each other's lip against spring pressure. Faces are mostly of carbon/teflon. While in operation, casing face face of seal remains stationary and other half mounted on pump shaft rotates. In order to avoid damage because of friction between mobile and stationary face, a cooling fluid are provided. If seal is fitted properly with proper cooling medium, it long last. Mechanical seals are generally meant for high pressure/ RPM corrosive and expensive liquids to avoid waste and accident to operating personal.
two parts. the cup and a spring inside the cup,
Two Parts Static And rotating Static in seal flange rotating with sleeve means primary seal and secondary seal.
It is an Engineering developed sealing materials to stop leakages like in the Oil & water pumps under pressure.It is designed to avoid pressure loss in the system which affect the operation of the system.The seal is composed of different materials suitable to any fluid use.Seal materials like Teflon & Graphite combine.Improper use of Mechanical seals causes heavy shaft scoring & leakages.
a mechanical seal is a seal to utilised in rotating equiptment such as pump mixer blowers and compressor when pump operate liquid could leak out pumpbetween the rotating shaft and the stationary pump casing since the shaft rotates preventing this leakage can be difficult
