Seals in PurgeX pumps normally operate over millions of cycles without significant wear.  The majority of applications do not require seal replacement.

 

This Seal Replacement Kit has Viton liquid contact seals and is suitable for PurgeX models:

 

·          B3162-204

·          B3352-204

 

Replacement Procedure

 

PurgeX seals should be carefully replaced in a clean environment.  Remove the current seals from the unit.  Wash the remaining components with mineral spirits and allow them to dry completely.  Apply oil to the new seals before assembling.  Step by step assembly instructions can be downloaded using the link on this page.

 

Note: If the evacuation valve (A7440-2) is removed from the assembly at any time, it must be replaced with a new evacuation valve or the warranty is void.
