Lubricant Solves Pneumatic Actuator Failures on Filling Machine


At a food processing facility, equipment that is used for filling prepackaged, serving containers of pastes, sauces, and creams would typically fail by sticking at start-up. The situation was especially bad, over a three day holiday weekend, when moisture would build up and cause hang-ups. Internal surfaces were pitted and contaminated with a sticky residue. The customer was using USP white oil to lubricate the pneumatics because they required an NSF H1 lubricant. Since USP white oil does not have enough water elimination properties, water was not displaced from the metal surface of the pneumatic systems.

Product The local Chesterton representative recommended Chesterton 650 Advanced Machinery Lubricant (AML).

It is NSF H1 certified and 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 the filters. Chesterton 650 AML was filled in the top oil bowl of the pneumatic lubrication system. Cylinders were cycled for 2 – 5 minutes to allow fresh 650 AML into filling equipment.
