  • Page 48: Stuffing Box Operation

    5.20 Stuffing Box Operation On units to be doweled (except those noted above), drill through two diagonally opposite feet of the pump into the bedplate. Use a reamer with a ¼" per foot taper. The dowels should extend well into the bedplate but project above the pump feet.

This device guards against possible damage due to running the pump against a closed valve. Constant open by-pass orifice between the pump discharge and any check or regulating valve in the discharge line.

  • Page 50: Maintenance

    These bearing lubrication sections list different temperatures of the pumped fluid. If the pump is ATEX-certified and the temperature of the pumped fluid exceeds the permitted temper- ature values, then consult your ITT representative. All bearings operate at some temperature above that of the surrounding atmosphere, unless cooled.
