Advanced Synthetic Barrier Fluids for Mechanical Sealing Applications

Xaerus barrier fluids are formulated using high-performance, non-reactive synthetic base fluids selected for their exceptional thermal and chemical stability. Advanced additive technology provides enhanced oxidation protection, particularly in demanding high-temperature operating environments.

The highly stable synthetic formulations deliver reliable sealing performance across a broad operating temperature range, while their excellent viscosity characteristics provide outstanding low-temperature fluidity and high-temperature stability.

Xaerus barrier fluids are designed to help maintain cool, clean and deposit-free seal surfaces, supporting reliable seal operation and extended equipment performance.

Available Fluid Chemistries

  • PAO – Polyalphaolefin
  • PAG – Polyalkylene Glycol

Typical Application

  • Double Mechanical Seals


Xaerus barrier fluids provide a high-performance lubrication and cooling solution for double mechanical seal systems operating under demanding temperature and process conditions.
