Early pump models created a seal in one of two ways: 1) packing pliable rings around the shaft and compressing them into a seal housing until they contacted the shaft; 2) filling the seal housing with multiple bushings with close clearances over the shaft. Depending on the mechanical seal type, there is often additional assembly work such as placing the carbon primary ring into an adapter or assembling carbon components into a seal head. Under compression, the seal is elastically deformed, producing internal stresses and generating a reaction force on both the top and the bottom of the sealing gap. face seal concept of a mechanical o ring design. Bright Hub Engineering.

Manufacturers & Exporters of Floating Seals, Duo Cone Seals. is a leading manufacturer and exporter of Mechanical Face Seals world-wide. DiamondFaces - the ultimate performance boost for your mechanical seals. In mechanical face seals, elastomers tend to take second chair because the primary seal—the dynamic seal between the housing and rotating shaft—is achieved by sliding contact between the pair of stiffer, lapped-flat sealing faces, one stationary in the housing and one rotating with the shaft. KLOZURE ® Mechanical seals for pumps, agitators mixers and other rotating shaft applications are available in both lip and face seal designs in four primary styles and a wide range of sizes.
