Aesseal Curc Replacement Cartridge Mechanical Seals

The CURC lineup offers a robust cartridge mechanical seal platform:

• Flexible, with wide face-material choices.

• High-performing, with solid ratings up to 15 m/s speed, 125 mm shaft, and ~25 bar pressure.

• Durable, thanks to SiC face protection from impact and hydraulic balancing.
  
  
  
  

  Core Design Features

   

  • Self‑aligning stationary head, centering the seal faces to prevent angular misalignment and reduce stress on SiC faces .

  • Advanced third-generation SiC optimization, minimizing metal-to-SiC impact at startup to prevent stress cracks .

  • Balanced hydraulics reduce heat, power consumption, and enhance face stability under pressure.
    
    
    

     Performance Parameters

    • Shaft diameters: 24 mm to 125 mm (approx. 1″–5″).

    • Pressure rating: Up to 2.5 MPa (~25 bar / 362 psi) in general; some aftermarket versions specify up to 28 bar (~2.8 MPa) .

    • Temperature range: −20 °C to +150 °C (standard); some variants support up to +220 °C .

    • Maximum speed: ≤ 15 m/s surface speed .
