7.1 Periodic Inspection, Condition Monitoring, and Preventative Maintenance
• Periodic inspections (ideally once a month) and preventative maintenance are recommended as the
best means of preventing breakdown and keeping maintenance costs at a minimum.
• Maintenance personnel should look over the entire installation with a critical eye, each time the pump is
inspected.
• A change in noise level, amplitude of vibration, or performance is an indication of a possible impending
trouble and must be investigated for probable causes.
• During inspection the pump and driver should be checked for performance and change in noise or
vibration level, loose bolts or piping, dirt and corrosion. It helps to develop a vibration trend analysis
based upon periodic vibration reading recordings. This helps determine changes in equipment condition
and optimum repair frequency.
• Variances from initial performance are an indication of changing system conditions, wear or impending
breakdown of the unit.
• Clean and repaint all areas that are rusted or corroded.
7.2 Packing Box Maintenance
Maintenance of the packing box will consist of greasing the box when required, tightening the packing gland
occasionally as the leakage becomes excessive, and installing new packing rings or sets as required.
7.2.1 Packing Box Greasing
• Under normal operation, once a month greasing of the packing box is typically adequate.
• Use good grade multipurpose grease such as Chevron Industrial Grease - Medium or Marfak
MULTIPURPOSE #2.
7.2.2 Replacing the Packing
• Remove the gland and old packing. If the box contains a lantern ring remove this and the packing below
it.
• Inspect the shaft or sleeve for score marks or rough spots. Ensure that the bypass holes (if required) are
not plugged.
• Repair or replace badly worn shaft or sleeve. If the wear is minor dress down until smooth and
concentric. Clean the box bore.
• Oil the inside and outside of the replacement rings lightly and install in the box, staggering joints 90°. Be
sure to replace lantern ring in proper position when used.
NOTICE
Formed replacement packing rings are recommended and are available from the factory.
