AES Split Seals (AES ISOS)

The ISOS™ (inflatable shut-off seal) is fitted between the pump and a radially-divided seal, to form a separate seal when required, allowing the quick and easy removal of the mechanical seal. The ISOS™ works around the principal of surrounding the shaft with an inflatable elastomeric bladder.

Under normal operating conditions, when the mechanical seal is working, the bladder remains unpressurized. When the mechanical seal fails or needs removing, the bladder can be inflated, thereby mechanically sealing the shaft. The seal can then be easily removed without draining or isolating the equipment.
