Simple Installation and Increased Reliability for General Duty Applications
The 250 Double Cartridge Seal provides sealing security that packing and conventional single mechanical seals cannot match. With a compact cartridge profile designed to fit standard ANSI/ISO process pumps, the seal is designed to install easily and reliably. The single screw clamp lock ring design (250L) further increases efficiency and reduces installation error.
Introducing optimized seal face geometry engineered through computer modeling and a durable double balanced design, the seal is engineered with improved lubrication, helping the seal to run cooler and longer. With proven Chesterton reliability, the 250 Double Cartridge Seal is an economical upgrade to increase the life of your equipment.
