Double Mechanical Seal
bridges the product range gap between and 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.
Features:
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
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.
