Tech Tip: Choosing the Proper Lubricant for Pumps & Valves

EPDM is the standard elastomer on many pumps and valves and is not compatible with petroleum-based products. Using lubricants such as the popular Petro-Gel in these applications is not a good choice as it will degrade your equipment elastomers and decrease the life of your parts.

Due to the high melting point, Petro-Gel and similar non-CIP lubricants have the potential to contaminate your product with bacteria such as Listeria. Petro-Gel has a melting point of 190°F, and typical CIP cycles are only 160-180°F, meaning the residue will not melt and clean away. If a spare part somehow came in contact with bacteria, the high melting point of these non-CIP lubricants would function to protect the bacteria during the CIP cycle and could contaminate your products!

To lubricate your EPDM pump and valve parts, use Haynes or McGlaughlin CIP films (312-2020 or 435-2005). With melting points of 120°F, they will wash away completely during your CIP cycle.
