FINAL RE ASSEMBLY
The last packing ring should never protrude beyond the stuffing box face thus allowing the gland
follower to 'start' in the stuffing box. If this is not the case, then dismantle and check that the correct
number of rings have been used and that they have seated correctly.
Bring the gland follower up squarely against the last packing ring and finger tighten the securing nuts
evenly.
Turn the shaft to ensure that no binding is taking place.
Pressurize the stuffing box, ensuring their is no trapped air. The gland should start to leak heavily
almost immediately. If it does not stop the pump immediately and investigate.
GLAND FOLLOWER ADJUSTMENT
After the pump has been running for 10 minutes at full pressure, adjust the follower nuts by one sixth
of a turn every 10 minutes until there is a small leakage only. This leakage is essential to ensure
packing is lubricated.
TABLE 4 ROUTINE MAINTENANCE CHART
Every Week
Visually check for leaks.
Check for vibration.
Hand test bearing housing for any sign of temperature rise.
Adjust gland as necessary to maintain slight leakage.
Every Month
Check bearing temperature with a thermometer.
Every 3 Months
Check running hours and consult re-lubrication interval chart.
Check grease lubricated bearings for saponification - i.e. signs of any
deposits, oil separation and undue hardening and softening of grease.
Every 6 Months
Check running hours and consult re-lubrication interval chart.
Check soft packed gland packing, where fitted, and replace if necessary.
Check shaft or shaft sleeve for scoring.
Check alignment of pump and motor.
Check holding down bolts for tightness.
Check coupling for wear.
Every Year
Check rotating element for wear.
Check wear ring clearances.
Clean and re-grease bearings.
Check running hours and consult re-lubrication interval chart.
