PURGE CONNECTOR (P)

left border  
 

In systems where sediments can collect between the outside of the internal liner and the inside of the bellows element, a threaded purge connector can be added to the upstream end connection as shown. Clear gas or liquid can be injected to periodically blow collected material out, or can be continuously supplied during system operation.
