Mechanical Seals

Creating a mechanical seal with two flat faces and secondary seals did not happen till about 1905. Often considered a bit of a mystery they actually are quite simple. All mechanical seals utillize 2 incredibly flat faces (2-3 light bands) that are pressed together by an energizer (usually a spring of some sort). One mechanical seal face turns and one remains stationary. The seal faces are the primary seals.

Mechanical seals must have secondary seals

Secondary seals include o-rings, rubber bellows, ptfe wedges, flexible graphite wedges and gaskets. The secondary seals for your mechanical seal will generally be made of rubber (nitrle, buna-n, EPDM, Neoprene, PTFE, FKM, Viton, Kalrez) o-rings or gaskets.

Installation of Mechanical seals

50% of mechanical seal failures are due to poor installation. If the seal is a basic rotory and stationary type seal, they can be over compressed or undercompressed if the rotary is not positioned correctly.

Cartidge Mechanical seals

Are the solution. To prevent the problems associated with seal installation mechanical seals are available in single units called Cartridge seals. Cartridge Seals include: Rotary, Stationary, Secondary Seals, Sleeve, Gland and Lock Collar.
