Install the packing rings:
a) Twist each of the five packing rings sideways in order to easily get them around the shaft.
You can set the sixth ring aside until the packing is adjusted for leakage after the first startup.
b) Start the first ring into the stuffing box.
c)
Use your fingers to position the entire ring in the stuffing box.
d) Tap each ring down using a split wooden bushing and push the packing ring down firmly until it
seals on the shaft and bore of the stuffing box.
e) Stagger the ring joints 90° apart.
You can use the split gland as a tamper for the top ring.
10. Install the split gland and thread the nuts on the split gland studs.
11. Hand-tighten the nuts.
12. If an optional bypass line is furnished, attach it to the tube fitting in the stuffing box.
Final adjustment of the stuffing box must be made at pump start up. This final adjustment applies to all
stuffing box styles. A properly packed stuffing box needs to be loose enough to allow you to manually
turn the shaft.
