Pro tips for repacking a pump

Repacking a pump can seem like a fairly straightforward process, but there are a few subtleties that are often overlooked by novice and experienced pump packers alike. Overlooking these details can make a repacking job harder than it really is, consuming more time and increasing the risk of a poor start-up.

Repacking a pump can be viewed as a four-part process. The process consists of the following steps:

  1. Removal
  2. Inspection
  3. Installation
  4. Start-up

For each step of the repacking process, we present some tips for successfully repacking a pump and obtaining a trouble-free start-up and operation.

Tip #1: Be prepared!

Before commencing a repacking job, it is wise to ensure that all the needed tools and supplies are on-hand. A good idea is to create a repacking kit which contains everything necessary to carry out the repacking. A well-stocked kit contains the following:

Tip #2: Use correctly sized packing pullers

Removal of the old packing is best done with the use of correctly sized packing pullers. This ensures that the old packing is completely removed from the stuffing box. If any residual packing is left in the stuffing box, it could interfere with the seating of the new packing.

Tip #3: Don’t overlook inspection!

Sometimes, due to the need to meet tight maintenance schedules, inspection of the pump shaft and stuffing box is overlooked. Inspection is a key part of every repacking job! Only by fully inspecting the pump shaft and stuffing box can one detect abnormal wear and tear – wear and tear that could be a signal of a potential future problem or failure. Performing a thorough inspection when repacking can lead to effective preventive actions – an ounce of prevention is worth a pound of cure!
