Hydraulic Oil Quality Assurance Bulletin - Demulsibility


Modern hydraulic systems are under greater pressure than ever before to provide maximum power output with maximum energy efficiency and economical operation. A common problem encountered by operators is poor demulsibility in the hydraulic oil they are using, which means water does not separate properly from the oil. At GB Lubricants, we carefully formulate our hydraulic oil range to optimise and maintain your hydraulic system.

Poor demulsibility is caused by:

• Particulate contamination

• Base oil quality

• Contamination from other oils

Poor demulsibility causes:

• Corrosion

• Premature wear

• Oxidation

For optimum performance in your  machinery, always ensure you are using the correct hydraulic oil.

GB Lubricants' Unipower® hydraulic oil range meets industry specification DIN 51524 part 2, which means its formulation has been tested for foaming, water separation, oxidation stability and more. Our products also meet exacting OEM specifications.
