Mechanical Seal to Injectable Packing
Mechanical Seal to Injectable Packing
(OP)
We're looking into switching our mechanical seals out in our double suction cooling water pumps to injectable packing to minimize maintenance costs. What are your experiences with doing this? It seems like there's almost no downside to injectable packing on non-hazardous services since you would just reinject the packing for a leak.
The only disadvantage I see is an increase in power consumption due to increased shaft friction.

RE: Mechanical Seal to Injectable Packing
let us know what problems you are having
RE: Mechanical Seal to Injectable Packing
What kind of leaks do you have with mech seals that packing will cure?
RE: Mechanical Seal to Injectable Packing
If you have present problem with the seal you are going to have more if you switch to packing.
One of the things that we noticed on big between bearings pump is if you have internal misalignment. Then the seal will flex twice every revolution. You may resolve it by moving to stationary flexible.
RE: Mechanical Seal to Injectable Packing
sounds like i'll just scrap the idea of switching to injectable packing.
thanks for the replies
