The CDFI™ / CDFC™ bridges the product range gap between the FIDC™ and DMSF™ differentiating itself in two areas. The hybrid design offers a metal-to-metal inboard drive and an integral bi-directional pumping device, allowing the seal to fit in radial cross sectional spaces as small as 0.312″ (8mm). The CDFI™ / CDFC™ is available in any AESSEAL^® standard seal face and elastomer combination.

• Integral deflector guides barrier fluid under faces and extends seal life
• Incorporates highly effective bi-directional pumping ring to maximise barrier flow and increase seal life
• Bi-Metal CDFI™ / CDFC™ options also include exotic allow wetted components at minimum price premium for use with corrosive chemicals
• Hydraulically balanced seal-face technology for reduced power consumption
• Non-shaft-fretting sleeve elastomer and positive set screw shaft drive
• Independent seal face design to enhance safe containment of process fluid in the event of damage to any individual sealing element
• Multiple spring seal face loading
• Sizes available from 1.125″ to 5.000″ (28mm – 125mm) in standard and ANSI Plus gland formats
