These devices are available in a wide range of materials, shapes, and sizes, and are suitable for use as secondary seals in static applications. STATIONARY SEATS: Ceramic, Silicon Carbide, Tungsten Carbide, Stainless Steel. All Rights Reserved. Mechanical seals in pumps are challenged by three very specific things: dissolved solids, undissolved silica or sand, and the pH of the fluid. These other types include diaphragm, hydraulic, pneumatic, balanced, unbalanced, pusher, non-pusher, and conventional seals. Although these devices use similar terminology, industrial standards classify them in a category separate from that of the seals generally referred to and employed in industrial and commercial applications—i.e., mechanical seals. mechanical seal are the seal rings on which a mechanical force is acting, generated by springs or bellows , and an hydraulic force, generated by the process fluid pressure. The seal between the rotating member and shaft or shaft sleeve (4).
