What is a mechanical seal and how does it work?

Mechanical seals are devices that control the leakage of fluid between a rotating shaft and the pressurised casing on rotating equipment. Typical applications include centrifugal pumps, reactors, mixers and compressors. Originally developed to overcome gland packing-type seal limitations, modern seals are designed to reduce emissions and improve rotating equipment performance. Figure 1 (to the right) […]
