General Duty Double Cartridge Seal
Simple Installation and Increased Plant-Wide Reliability in General-Duty Applications.
Built on Chesterton’s AXIUS™ platform of performance cartridge seals,the Chesterton® 2510 Double Cartridge Seal is designed for maximum reliability, making it an ideal solution for plant-wide standardization of general-duty applications in a field-repairable package. Engineered with a hydraulically double balanced construction, the seal is designed to endure any pressure reversals, shifts, or surges, keeping the faces reliably closed.
The 2510 Double Cartridge Seal offers increased cooling and flow capabilities, resulting in cooler operating seal faces – even at elevated temperatures – through the design of unique sleeve and gland features. Integrating proven technologies from Chesterton’s long history of mechanical seal designs, the 2510 Double Cartridge Seal sets the new standard for general-duty double cartridge seals.
