Leybonol vacuum oil.
If you have an oil-sealed vacuum pump, you probably know that the oil performs three important functions for the pump to function satisfactorily. It seals, lubricates and cools the vacuum pump. All vacuum pumps that are sealed with oil need to be handled in the same way as you handle the oil in your car. You need to check the amount of oil at regular intervals so that the level is the right one. You also need to check that the oil is not contaminated by particles and dirt and anything else that is present in your process. The oil filter plays an important function, but sometimes the oil has to be replaced in order for the vacuum pump to maintain continuous high performance.
