Cartridge Mechanical Seals Aesseal Cksa Ckda Glandless Cartridge Double Seal to Suit Ahlstar up Pumps
- Product No.：CKDA/CKSA Double
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.

Advantages of Double Mechanical Seals
A double or dual mechanical seal consists of two independent seals mounted within a seal chamber outside the pump, which is flushed with an independent supply. This makes them ideal for sealing hazardous liquids, liquids with abrasives or liquids that are corrosive, as the seal faces only see clean lubrication greatly increasing mechanical seal life.
AESSEAL double mechanical seals have independent seal-face designs, to enhance safe containment of process fluid in the event of damage to any individual sealing element.
