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 fluctuations

• Axial displacement capacity to accommodate machine build tolerance and differential thermal expansions

• Seal face design optimized using FEA and hydrodynamic algorithms

• Seal-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
