Mechanical Pump Oils

We offer a range of new oils, Ultragrade^® 15, 19, 20 and 70, which result from a new process. Most manufacturers use a solvent refining process, whereas these oils are produced by a unique hydrotreating process. This process eliminates nitrogen, sulphur and oxygen, and aromatic hydrocarbons, leaving a clear base stock essentially free of impurities.

When combined with additives, the Ultragrade^® oils give improved vacuum performance, thermal and oxidation stability and rust inhibition. The anti-oxidants included in the oils enable the pump to withstand high operating temperatures without oil degradation, so extending intervals between oil changes.

The properties of the oils allow them to be used in a wide range of applications. New Ultragrade^® 70 oils are the best choice for large pumps used in heavy-duty, cycling applications. Contact us for detailed recommendations.
