GLAND PACKING SELECTION

There is a wide range of packings to choose from for every application. Your decision to standardize on Gasket Manufacturing Corporation brand of pump packings has already gone a long way in solving most of your pump packing problems. To assist you in the correct selection of gland packing for your application you need to know the following:

Is the packing required for a pump or a valve? If for a pump you need the following information:

1.      Determine media to be sealed.

2.      Dimension of stuffing box inside diameter.

3.      O/D of shaft and I/D of stuffing box eg. shaft = 20mm, stuffing box = 40mm. By dividing the difference by 2 you know the correct size packing required. 40-20 = 20÷2 = 10mm

4.      Check the mechanical condition of your equipment. Replace if found faulty.

5.      Determine the shaft velocity in metres per second.

6.      Determine media temperature in stuffing box.

7.      pH of media to be sealed.

8.      Stuffing box pressure. If unknown, work on 2/3 of discharge pressure.

9.      Any other special requirements, such as,
a) non-contamination of media to be pumped or
b) severe abrasive slurry, etc.
