Product Detailed Description
FW-HRKS Mechanical Seal for PFA, PTFE, PE-UHMW, PFA-P Lining Pump Used for Highly Acidic Applications and Chemical Centrifugal Pumps.
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. All contacting parts are non-metallic which prevents the Inboard seal parts to get corroded in all extreme acidic applications. 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.
