Typical Applications for Mechanical Seals

We typically deal with three types of mechanical seals in critical aerospace and industrial applications: contacting face seals, non-contacting face seals and bellows-energized contacting seals. Technetics Qualiseal® mechanical seals are custom engineered to meet the demanding requirements in these situations. Spring-energized contacting face seals are used in low-pressure, low-speed applications. In aerospace applications, these mechanical seals would typically be used for oil pumps, scavenge pumps, fuel transfer systems, and gearboxes. They are in mixers and other slower-rotating applications in the industrial environment. In higher-speed applications, they are in gearboxes, starters, and accessory starters on engines. Hydraulics, fuel pumps, industrial compressors or screw compressors require mechanical seals that can withstand higher pressures. Small engine main shaft applications may need bellows-energized contacting seals. Aerospace and industrial main-shaft applications, like compressors, may need circumferential seals. Essentially, Technetics can put a seal anywhere there’s a bearing. 0:10 – Spring-energized contacting face seals 1:17 – Bellows energized contacting face seals 1:28 – Circumferential Seals Learn more: https://technetics.com/technetics-products/mechanical-seals/
