Product Detailed Description

FW-Cartex (SN/DN) Mechanical Seal for Chemical Centrifugal Pumps, Vacuum Pumps, Compressors

Structural Features:

single end (SN) and double end (DN), multiple springs, balanced (SN) and double balanced (DN), independent direction of rotation, still type cartridge seals. This component has good compensation and is suitable for the situations of sudden changes of system pressure. The compensatory ring is inside the flange and the elastomer rings protect the springs at the medium side to make sure no contact between the springs and the medium, which prevents the corrosion to the springs. Pumping slot design in the sleeve. Pin transmission design makes the component more reliable. The seal has a simple structure and is easy to install. Both axial and radial dimensions are small and the seal is good to replace gland packing.
