High Performance Mechanical Seals

The CFFC™ and HPVD™ are dual seals. (The CFC™ and HPVS™ are the single versions.)

These robust seals are designed for use on difficult applications, including oil pipeline pumping, water injection and boiler feed duties. 


  • High speeds - Stationary multi-spring designfor even face loading
  • High pressures - Robust seal-faces minimize the effects of pressure distortion 
  • Monolithic seal-faces - maintain flatness under temperature flictuations
  • Axial displacement capacity to accommodate machine build tolerance and differential thermal expansions
  • Seal face design optimized using FEA and hydrodynamic algorithmsSeal-face loading factory set and statically tested prior to despatch
  • Sculpted lug drive for improved torque transmission
  • Compact and robust design allows seal to be fitted on close bearing centre pumps
