KSB 00332386 is a mechanical seal reference with the designation H12N/..-E10-R BSM1GG-G. The H12N belongs to the balanced, conical-spring pusher-seal designs for stepped shafts and depends on the correct direction of rotation. The material code specifies resin-impregnated carbon graphite for the rotating face (B) and CrMo cast steel for the stationary seat (S), with PTFE-wrapped FKM secondary sealing elements (M1). The shaft diameter and installation dimensions must be confirmed against the pump before selecting a replacement. The corresponding KE MOTION HYDRO product reference is BT-1.
