Invert emulsions containing EP and anti-wear additives together with a dual inhibitor system which provides rust and corrosion protection.
Suitable for use in air operated submersible pumps, such as Sludgepiper, Sandpiper, Atlas Copco, DOP15 and Whiteall, used for the removal of water from underground mines.


  • Mist and fire resistant invert emulsions that enhance operator safety – particularly those operators working below ground or in enclosed areas
  • Extends equipment life by protecting against wear and corrosion
  • Operating speeds can be maintained because of reduced viscous “drag”, increases productivity


  • Recommended for major rock drill equipment manufacturers including Sandvik, Atlas Copco, Gardner Danver and SIG
