Brayco Micronic SBF

Castrol Brayco Micronic SBF is a 2007 OSPAR compliant fluid with no substitutable components.

Castrol Brayco Micronic SBF utilises highly refined base oil technology and is specifically formulated for use as a barrier fluid in subsea pumps. The fluid incorporates all the features required for reliable operation in this demanding subsea environment.

Developed under a Quality Management System with ISO 9001:2000 certification and an Environmental Management System with ISO 14001:2004 certification for Research and Development.

• Castrol Brayco Micronic SBF is designed specifically for use in subsea pump applications.
• The product has excellent electrical insulation properties that make it suitable for internal cooling high-voltage electric motors.
• Rated for operation over a temperature range of -30ºC (-22ºF) to 120ºC (249ºF).
• The low pour point also allows use in areas where low ambient temperatures prevail.

• Fully compliant with 2007 OSPAR environmental legislation and does not contain any “substitutable” components.
• Excellent insulating properties make it suitable for internal cooling high voltage AC electric motors (Tested to IEC 156).
• Physical and chemical testing has demonstrated that Castrol Brayco Micronic SBF is compatible and miscible in all proportions with typical mineral oil-based fluids.
• Castrol Brayco Micronic SBF provides corrosion protection with water contamination according to IP135B, with up to 5% seawater contamination.
• Castrol Brayco Micronic SBF has excellent lubrication performance.
• Castrol Brayco Micronic SBF is compatible with materials commonly used in subsea pumps.
• Compliance with 2007 OSPAR environmental legislation ensures minimal impact on the environment.
• Allows reliable operation when exposed to the operating conditions of subsea pumps.
• Excellent lubrication characteristics ensure good performance in both radial and axial bearings, with stable and low levels of leakage across mechanical seals.
• Compatibility and miscibility properties of Castrol Brayco Micronic SBF with typical mineral oil-based products allow easy upgrade of existing systems by top up.
• The low pour point of the fluid allows operation in low ambient temperature environments.

Metals to be avoided Being a non-aqueous medium, galvanic corrosion is minimized and hence Castrol Brayco Micronic SBF is suitable for use where a wide variety of metals are used within the system. For coating compatibilty data, please contact Castrol Offshore.

Ethylene Propylene rubbers (EPR, EPDM) are not compatible with Castrol Brayco Micronic SBF or any other hydrocarbon based oils. These materials must be changed out where equipment is to be used with Castrol Brayco Micronic SBF. Silicone based insulating materials, and polyester based plastics have limited compatibilty. Testing is recommended

User Advice

Paint and other Surface Coatings It is recommended that in accordance with good working practice, the internal surfaces of the equipment should not be coated. Where it is necessary to use internal surface coatings such as PTFE these should be assessed for suitability of use. Manufacturers’ guidelines should be observed with regard to cure times and temperatures, and as with paint systems, surface preparation specifications should be adhered to.

Environmental Compliance

Castrol Brayco Mirconic SBF is compliant with 2007 OSPAR environmental legislation, providing a large global operational footprint.

Care and Handling

Avoid prolonged or repeated contact with skin. Wash thoroughly after handling.

Storage

All packages should be stored under cover. Where outside storage is unavoidable drums should be laid horizontally to avoid the possible ingress of water and the obliteration of drum markings. Products should not be stored above 600C, exposed to hot sun or freezing conditions.
