Is there a method to test a pump that uses packing for a seal when on the bench and no motor attahed? This is so the pump is not installed and then find out that it is leaking way to much when operated.

Leaking from where - the castings, the casing joint, the gland / stuffing box? please explain.

I am looking for a test method for packing a pump that would indicate there is a problem before it is installed.
Thank you to all who respond.

= test a pump without having the motor installed and find out whether there is leakage over the packing (shaft seal) or not.

Sorry, have never seen the need for such a test. If a pump with new packing leaked "way too much" when run, then it would probably take less time to check why it was and then repack, if the installed packing could not be taken up a bit more.

There is no way to test the packing on the bench, the pump needs to be run and the packing bedded into the stuffing box over a period of run-time.

There is very little to go wrong with packing - insufficient compression, over compressed packing or wrong size packing ? Remember it must leak to work properly to lubricate... Ash Fenn 字串1

Remove current packing and repack with proper packing leave gland out to full for further tightening under pressure. There is no need to test as long as you use the proper packing. Contact a packing manufacturer/supplier and read up on packing for oil/water/steam packing at pressures you need.
