A mechanical seal is a crucial component whose beneficial life considerably impacts the overall reliability and robustness of pump or centrifugal compressor. Unscheduled or premature failure of the seal leads to increased maintenance and increased overall equipment costs to the user. The overall performance of a mechanical seal often is most affected by the performance of the faces and the intervening lubricating film. This primary element of a mechanical seal represents a classic issue in the science of tribology, the study of friction, wear and lubrication.

The demands placed on seal faces require careful attention to the problems of wear resistance, chemical compatibility, mechanical and thermal properties—all of which are determined by the end use application and overall seal design. When a mechanical seal is utilized in a pump, the liquid in the pump is employed to cool and lubricate the seal faces.

Mapping GE business units on a BCG Matrix

BCG matrix is developed based on the product life cycles and gives a hint of what areas should the business give priorities among the product portfolio (Hambrikc et al., 1982, p. 452).
