What are the different types of mechanical seals?

There are many different seal types and designs when it comes to mechanical seals. Here are a few common examples for those used in Viking pumps:

Single component seal – made up of a static and rotary seal face and pushed together by a spring. Primary seal is created by a film of process liquid between the two seal faces. Secondary seals are created by o-rings, bellows, or gaskets.

Cartridge mechanical seal– all of the working parts of the come in a pre-set housing. This makes installation significantly easier.

Double Mechanical seals – These seals utilize two mechanical seals in a housing. A barrier liquid is applied into the housing between the two seals. This prevents exposure of the process liquid to the environment and it used for toxic, flammable, or difficult to seal liquids.
