Flowserve Aquapac Water‑Lubricated Compressor Seal

Aquapac is a high speed, water lubricated mechanical seal engineered for compressors that use ultra pure water as the sealing fluid. It removes the need for oil or inert gas systems, prevents process contamination, and delivers stable sealing with extremely low leakage at speeds over 100 m/s. Validated across demanding operating conditions, Aquapac provides reliable, emission free performance for applications where water is the preferred sealing medium and low-leakage, contamination-free operation is essential.

Contamination free operation
Water Lubricated Sealing
No oil or inert gas systems
Stable Performance
High speed (> 100 m/s) stability

  • Zero Emission Operation
    Eliminates the need for oil and inert gas systems, preventing contamination and ensuring safe, clean operation.
  • High Speed Performance
    Maintains sealing integrity at peripheral speeds above 100 m/s for demanding compressor operation.
  • Optimized Thermal Management
    Internal geometries manage heat effectively during continuous high speed operation without need for complex cooling systems.
  • Superior Leakage & Tightness
    • Dynamic: Controlled leakage during operation
    • Static: Back pressure tightness prevents process loss
  • Application Flexibility
    Ideal for processes where water is the preferred sealing fluid and low leakage, zero emission performance is essential.
