Stuffing box installation
This pump is a sealless design. Therefore, when temperatures exceed 180°F (82°C), you must move the
thrust bearing away from the heat source in the pump by adding the upper stuffing box. Air can then
circulate around the bearing in order to keep it cool.
The upper stuffing box is also used to minimize vapor emissions when the pump handles controlled
substances.
