CASTROL ALPHASYN EP 320
Synthetic Gear Oils
Application CASTROL ALPHASYN EP 320
The Alphasyn EP 320 have been formulated for use in all types of enclosed gears including heavy and shock-loaded gears and bearings where EP properties are required. Castrol Alphasyn EP 320 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.

Performance, Features & Benefits of CASTROL ALPHASYN EP 320 are:
- 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.
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 320 is fully compatible with nitrile, silicone and fluropolymer seal materials.
Alphasyn EP 320 is classified as follows: DIN Classification is CLP 320.
The Alphasyn EP range meets the requirements of:
- DIN 51517 Part 3
- Siemens MD for Flender Gear Units
- AGMA 9005 - E02
- AIST 224
- David Brown Type E
