KSB 01033227 is a mechanical seal reference with the designation M7F1/..-00 Q1BEGG. The M7F1 design is a spring-loaded pusher seal with an integrated pumping screw; the pumping feature is dependent on shaft rotation direction. The specified material combination includes sintered silicon carbide for the rotating face (Q1) and resin-impregnated carbon graphite for the stationary seat (B), with EPDM secondary seals (E). The shaft diameter and installation dimensions must be confirmed against the pump before selecting a replacement. The corresponding KE MOTION HYDRO product reference is NV-3.
