The M37GN belongs to the unbalanced pusher-seal family, using a rotating conical spring whose handed version must match the shaft rotation direction. The material code specifies shrink-fitted sintered silicon carbide for the rotating face (Q12) and sintered silicon carbide for the stationary seat (Q1), 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 NT-2.
