Glandless cartridge double seal to suit Ahlstar UP pumps
The CKSA™ and CKDA™ seals are designed to fit the full six bearing frame range of the AhlstarUP pump models.
AESSEAL® is believed to be the only seal manufacturer to offer a fully integrated and glandless cartridge mechanical seal range for these pumps, which were launched by Sulzer in 2006.
The CKDA glandless cartridge dual seal has been designed specifically for AhlstarUP pumps. The seal uses a multi-spring design that ensures the seal faces are evenly leaded and therefore improve seal life. The cartridge design makes installation simple and the seal can be retrofitted to existing pumps without modification. The seal includes an unique flow inducer (patent pending) that helps improve barrier/buffer fluid flow to remove heat from the seal and optimise the seal face cooling. The dual seal is hydraulically balanced ensuring that it performs well at high and low barrier to process pressure differentials.
