Food-Grade Lubricant Improves Reliability of Pneumatic Equipment


Case study EN350977 – Chesterton products – Chesterton Industrial Lubricants




A meat processing facility was experiencing repetitive malfunctions due to sticky residue from USP white oil. In a system that seals sausage and meats with pneumatic sealing machinery, it is vital that these parts are kept clean and healthy. The client wanted to remove this sticky residue, while also decreasing cycle time of the system as a whole. Chesterton recommended the Chesterton 650 AML which has since operated without any issues for 12+ weeks.

Products featured in the case study:

Chesterton 650 AML


At a meat processing facility, meat is extruded into a casing and sealed by “clips”. The process of stuffing the casing and mechanically sealing it with “clips’ is done pneumatically.

The facility was using white mineral oil to lubricate the cylinders and solenoid valves of the pneumatic system. After just six weeks of using USP white oil, the sticky residue would cover the solenoid surface resulting in malfunctioning.

The customer was interested in decreasing the cycle time of the pneumatic system.

The local representative recommended Chesterton 650 AML. This product is designed for lubrication of  pneumatic mechanism. It has excellent detergency and cleans the surface while it lubricates. Its excellent thermal stability reduces the residue and varnish formation. Chesterton 650 AML is NSF H1 certified and hence can be safely used in the food industry.

The in-line lubrication system was cleaned of the old white oil, and water was drained from filters. 650 AML was filled in the top oil bowl of the pneumatic lubrication system.

Chesterton 650 AML was simply added into the in-line oiler.


The client saw many benefits of this lubricant, including:

  • The 650 AML has been in operation for 12+ weeks without any issues. This has significantly exceeded the six weeks performance of USP white oil.
  • Actuation has been trouble-free. No sticking of the pneumatic cylinder or solenoid was observed.
  • There is virtually no odor.
  • Floor workers expressed the system is less noisy.
