Non-foaming Oil

Hawk Non-Foaming OilHawk Oil has been developed in conjunction with a leading oil manufacturer for the Hawk range of high pressure piston pumps. The Hawk oil is non-foaming, thereby reducing the amount of bubbles in the oil, and the amount of air in the bearings. This in turn increases the lubricating properties of the oil. The lack of emulsifiers in the oil reduces its ability to become milky in humid conditions.
