The CDFI / CDFC bridges the product range gap between the FIDC™ and DMSF™ differentiating itself in two areas.Also 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).Also The CDFI / CDFC is available in any AESSEAL® standard seal face and elastomer combination.
Features:
- Integral deflector guides barrier fluid under faces and also 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 also 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 also ANSI Plus gland formats
Directed Barrier Fluid Circulation
Removing the heat at the inboard faces is critical for any double mechanical seal. The CDFI / CDFC directed barrier fluid flow path achieves effective heat removal at both sets of seal faces.
Bi-directional Barrier Fluid Circulation
Developed using the highly efficient patented DMSF pumping ring the CDFI will effectively and reliably circulate barrier fluid irrespective of the direction of shaft rotation.
Alternatively, in applications which use an external barrier fluid circulation device, such as a PUMPPAC™, or where fluid convection require, the CDFC may be offered.
Fits in Thin Radial Cross Sectional Spaces
Like the FIDC™, the CDFI / CDFC can be installed on equipment with radial cross sectional spaces as small as 0.312” (8mm). This is typical on some smaller process pumps.
