WAVE SPRINGS COST EFFECTIVE MEANS OF SEALING FLUIDS IN MECHANICAL SEALS
by Henry Yates, Technical Sales Engineer
Mechanical seals are used for the sealing of rotating shafts against stationary housings, as in pumps, multiport swivels and agitators. The assembly of a mechanical seal is based on two main components: one “rotating” part and one “stationary” part.
The “rotating" part of the seal is usually fixed on a shaft or hub;
the “stationary" part of the seal is located at a static housing. The
sliding faces, which are part of the inner life of the seal, rotate axially
in opposition and are pressed against each other. The necessary
spring force preventing the seal from leaking when the apparatus is
idle is provided by flatwire wave springs.
The shaft is sealed by secondary sealing elements like Orings and the seal faces are statically sealed against the housing. The introduction of the pumped medium into the minimal sealing gap generates a lubricating film resulting in the desired sealing effect.
