Warranty

 
 

This Welch Vacuum product is warranted to be free from defects in material and workmanship. 
This liability of Welch-Ilmvac under this warranty is limited to servicing, adjusting, repairing, 
or replacing any unit or component part which in the judgment of Welch-Ilmvac has not been 
misused, abused, or altered in any way or damaged by ingestion of foreign material causing 
impaired performance or rendering it inoperative. No other warranties are expressed or 
implied. The method of executing this warranty: servicing, adjusting, repairing, or replacing, 
shall be at the discretion of Welch-Ilmvac. Vacuum pumps that have been operated within a 
vacuum system, or other system, for any period, however short, will be repaired under this

2. The product is returned to the factory or other designated service centers, freight prepaid.

 

3. The product in our judgment is defective through no action or fault of the user. 

 

If the product has become defective through misuse, abuse, alteration, or ingestion of foreign
