    Goulds 10K64 mechanical seal (1-1/4″) for Goulds 3656/3756 S-Group end suction pumps—SiC/SiC faces with Viton (FKM) elastomers for severe-duty service.

    The 10K64 seal assembly is the OEM-specified mechanical seal option for Goulds 3656/3756 S-Group pumps, commonly used for water supply, recirculation, and cooling applications. Please note our seal is 304SS, OEM specification call for 314SS for 10k64 (refer to note below)
