Final piping checklist
Check Explanation/comment Checked
Check that the shaft rotates smoothly. Rotate the shaft by hand. Make sure there is no
rubbing that can lead to excess heat generation or
sparks.
Re-check the alignment to make sure that
pipe strain has not caused any
misalignment.
If pipe strain exists, then correct the piping.
Stuffing box installation
This pump is a seamless 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.
