How to Adjust Fire Pump Packing Glands

If you’re looking for information on how to properly make a packing gland adjustment, you’ve come to the right place! Our blog today looks at the proper procedures for packing gland adjustments which will help extend the service life of your fire pump.

Follow these two steps:

  1. At the beginning of the pump operation, loosen the gland nuts and allow the packing boxes to leak liberally.
  2. Every 20 minutes, tighten the packing gland nuts, one flat at a time until the leakage has been reduced to about 60 drops per minute.

Please note: This process may require two to three hours.

By following these two steps, you will help lengthen the service life of your pump. Your extreme care is required to successfully reduce leakage below this amount.
