CFFC
These robust seals(CFC /HPVS and CFFC /HPVD ) designe for use on difficult applications, including oil pipeline pumping, water injection and boiler feed duties.
Finite Element Analysis and hydrodynamic algorithms are used to optimize the monolithic seal face design in order to maintain a stable fluid film. The seals engineere for maximum service life and have laboratory tested to extremes beyond their standard capability.
- 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 fit on close bearing centre pumps
TYPICAL DUTIES
Pressures up to 60barg (870psig) – CFC & CFFC
Pressures up to 90barg (1305psig) – HPVS & HPVD
Peripheral speeds up to 60m/s (12000ft/min)
Temperatures -40ºC to +260ºC (-40°F to 500°F) ***
*** At the seal the temperature would optimize by appropriate API plan
