Why Mechanical Seals ?

One of the most important advantages of the mechanical seal is its low leakage rate, resulting in a cost saving because of the reduxtion in lost liquid.
The hazards of fire and personal injury are also reduced when the pumps are handling inflammable or toxic products. Simplified pump designs and reduced maintenance costs are also plus factors.

Mechanical Seals Online Shopping in USA by mechanical-seal The Most Common Seal Consists of a stationary flat seat which is mounted into a gland or seal chamber, a spring loaded rotating face and a static seal along the shaft. The spring holds the rotating face to the stationary face and sealing occurs between the parallel faces. The static seals stop leakage between the shaft and the rotating seak head and also behind the stationary seat. The faces of the Mechanical Seal in operation do not actually rub against each other, but are separated by a thin lubricating film a few molecules thick. This can account for the slight weepage from some seals that are operating satisfactorily.

Since all the wear is on the seal faces, further savings are realized due to elimination of shaft or sleeve wear which would result in use of packing.
Most Seal applications will runs years with little or no maintenance. Time formerly spent on adjustment of packing can be used elsewhere.
