PREPARING USED PUMPS FOR STORAGE
Special care should be taken when pumps are removed from service prior to storage. Gasoline,
moisture, and foreign material that is left in the pumps will do extensive damage to the internal
working parts. This damage can be prevented, if entire pump is drained of gasoline, moisture, and
foreign material before it is put into storage.
1.
Remove drain plugs in rotary pump and separator body and in the top of meter cover. Then
lay pump on its side and elevate bottom of pump.
2.
Apply compressed air (no greater that 50 pounds [3.5barr]) through suction inlet to force out
all gasoline, moisture, and foreign material that may be trapped in the inaccessible cavities.
Be sure to wear safety glasses when using compressed air.
3.
Oil interior working parts by using a spray gun filled with light oil (free from gum content). The
oil may be blown in through the suction inlet.
4.
Shellac drain plugs and reinstate them in their proper positions. Use a cloth bag or wooden
plug to cover the suction inlet and discharge outlet to prevent dirt from entering interior.
