KSB 00136907 is a mechanical seal reference with the designation MFL85N/..-00 ASVM6G1. The MFL85N uses a rotating metal bellows in a balanced, single-seal arrangement, avoiding a dynamically loaded O-ring. The specified material combination includes antimony-impregnated carbon graphite for the rotating face (A) and CrMo cast steel for the stationary seat (S), with FKM secondary seals (V). The shaft diameter and installation dimensions must be confirmed against the pump before selecting a replacement. The corresponding KE MOTION HYDRO product reference is NMM-1.
