The Jabsco 18753-0256 is a high-performance mechanical seal designed specifically for Jabsco pumps. This seal head features a Tungsten Carbide Rotary Face/Primary Ring and is complemented by an 18-8 Stainless Steel Retainer, Spring, and a Viton Bellows/Elastomers. Engineered for durability, it is a compact, unitized, single spring, bi-directional Elastomer Bellows Seal with a one-piece construction that facilitates swift and simple installation or replacement.
The seal includes a full-convolution Viton elastomer bellows that offers excellent flexibility to handle shaft movement and wear. It is designed with a dent and groove positive drive arrangement to manage torsional stress on the bellows effectively. The precision surface finish enhances the seal's service life and reliability. The Viton elastomer drive ring secures the shaft to ensure effective sealing and drive, eliminating the need for set screws or drive pins. Additionally, the coil spring and ferrules maintain consistent face loading even under extreme conditions.
