Pump plunger packing is critical to assuring adequate downstream pressure of your system. Triangle Pump Components is proud to supply 838 style packing for general service applications. We offer die-formed and spring-loaded packing for extreme or high temperature conditions, made from the highest grade braided PTFE, Kevlar®, and graphite.
To ensure the safe, proper installation of your pump packing, follow these steps:
- Before beginning the installation, familiarize yourself with all federal and state safety and environmental regulations.
- As a safety precaution, make sure that the pump’s power source is completely turned off, locked out, and tagged before starting.
- Remove the old plunger and packing from the stuffing box and thoroughly clean and inspect the box as well as the sealing surfaces. Do not leave any old packing remnants.
- Install new packing per the manufacturer’s instructions, making sure to inspect and replace any worn throat bushings, lantern rings, or junk rings as necessary.
- Visually check the plunger for worn areas and damage, replacing them as necessary.
- Install the new packing, ensuring that the seal rings are facing the pressure end of the pump.
- Lubricate the plunger and insert into packing. Be careful not to damage the plunger’s exterior surface during installation.
- Connect the new plunger to the extension rod or crosshead. Turn the pump over by hand to make sure the plunger and packing are properly aligned.
- Tighten the packing per the pump manufacturer’s instructions. If you are installing adjustable style packing, do not tighten it until the dripping stops as this could inflict damage from overtightening.
- Start the pump and check its operation for leaks. However, it’s normal for the packing to drip small amounts of fluid.
- Note that the majority of situations involving excessive leakage are due to improper installation. Please be thoroughly familiar with manufacturer’s pump maintenance instructions before starting any installation.
