Description:

The Castrol Alphasyn™ EP gear oil range of high quality synthetic lubricants are based on poly-alphaolefin (PAO) fluids and sulphur/phosphorus Extreme Pressure (EP) additive technology providing good thermal stability and high load carrying capacity.

Applications:

The Alphasyn EP range have been formulated for use in all types of enclosed gears including heavy and shock-loaded gears and bearings where EP properties are required.

They are suitable for use in gear boxes where micro-pitting resistance is required and for a wide range of applications in extreme environments, for example mining and quarrying, marine applications and paper production. The use of a PAO base stock provides an inherently high Viscosity Index (VI) and low pour points making these products suitable for use over a wide temperature range.

The Alphasyn EP range is fully compatible with nitrile, silicone and fluropolymer seal materials.

Alphasyn EP is classified as follows:

• DIN Classification is CLP
• The Alphasyn EP range meets the requirements of:
• DIN 51517 Part 3
• Flender
• AGMA 9005 - E02
• AIST 224
• David Brown Type E

Advantages:

• Full EP performance gives protection of gears against wear and shock loading, including protection against micro-pitting.
• Good thermal and oxidative stability provides reliable operation and extended operating life when compared to mineral oil based products.
• High corrosion protection for gears.
• Inherently high Viscosity Index (VI) makes the product suitable for operations over a wide temperature range.
• Rapid air release and good performance in the Flender Foam Test prevents foaming and bearing damage.
• Good water separation and demulsification characteristics means reduced down time through prolonged lubricant life and increased equipment reliability.
• PAO based lubricant provides good compatibility with seals, paints and mineral oil based lubricants.
