KSB 01031938 is a mechanical seal reference with the designation H75F1/..-00 AQ1M2GG. The H75F1 arrangement is a balanced H7-series pusher seal with a pumping screw, whose design must correspond to the shaft rotation direction. The material code specifies antimony-impregnated carbon graphite for the rotating face (A) and sintered silicon carbide for the stationary seat (Q1), with PTFE-wrapped EPDM secondary sealing elements (M2). The shaft diameter and installation dimensions must be confirmed against the pump before selecting a replacement. The corresponding KE MOTION HYDRO product reference is BV-1.
