Reliable Sealing Solution 4 42C™ C A R T R I D G E S P L I T M E C H A N I C A L S E A L The Chesterton® 442C Cartridge Split Mechanical Seal is the latest innovation in split seal technology, combining superior seal performance with the ease of installation of a cartridge split seal. Our patented split seal technology addresses the inherent limitations found in conventional cartridge split seal designs, minimizing installation complications and excessive leakage. The 442C design also offers the greatest installation flexibility with it’s short axial length and flexible gland positioning....

Innovation Drives The 442CTM Cartridge Split Seal incorporates many new technical advancements that simplify seal installation and also significantly increase seal performance and reliability. Interlocking Face—Patent Pending Because the seal faces are split, the halves need to align correctly to seal. This has been one of the key problems associated with the installation of split seals and their sealing consistency. 1 The Interlocking Face eliminates this problem by uniquely keying the mating halves so that faces align correctly without having to manually work the face halves. Damage...

Seal Performance Engaged Spring Lifter The 442C uses a mechanism which automatically energizes the seal faces when the gland assembly is installed. During installation, the springs are not energized, minimizing potential installation damage which can occur. Split seal reliability is enhanced! Before Installation The spring lifter is engaged and retracts the stationary face, providing ample space between the seal faces for ease of installation. After Installation The spring lifter automatically disengages while the gland halves are assembled, initiating spring force between the two seal faces.

Proven Design, Superior S I M P L E F I E L D R E PA I R The Chesterton 442CTM can be repaired on-site without removing glued elastomers or parts or using special solvent to dissolve these glues. There are no measurements to take or elastomers to cut and then glue back in place as required in other split seal designs. The 442C Split Seal design simplifies split seal repair by using a standard spare parts kit, enabling you to lower your inventory costs to maintain operations. Special tools, precision spacers, or other custom components are not needed, simplifying the process and increasing...

Patented Adjustable Gland Gland tabs adjust to fit your equipment bolt position. Easy adjustment avoids “special order” gland designs necessary with other split seals. Interlocking Face Alignment—Patent Pending Advanced seal face technology accurately keys face halves to ensure seal face alignment and flatness. Spring Lifter—Patent Pending Permits gland assembly installation without spring force acting on the seal faces—eliminates face damage that can occur in conventional cartridge split seal designs. Integral Flush Ports Located 180° apart and, when combined with the adjustable gland,...
