Mechanical Seals arrow Style 550



Style 550




This seal represents an important tool for maintenance as well as an indispensable "part" for the OEM in manufacturing of modern centrifugal pumps. Hyraulically balanced, the seal incorporates a "full solid" monolithic face made of the most advanced ceramic materials, Hastelloy C multiple springs operating outside the fluid, large section drive pins and the dynamic ORing working on the actual sliding face. It is highly recommended for use in a wide range of fluids applications, particularly where the product may be aggressive or difficult. The metal body design of this seal is surface treated by saturation and offers excellent self-clearing properties, allowing maximum performance in heavy fluids, slurries, sewage pulp and paper applications achieving an extension of the MTBF terms.
