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.
