Repacking the "water seal kit" in your PW pump

Hey guys I was just wanting to see what all you pros out there are doing…

Do you guys replace your own seal kit when you lose pressure or do you guys take it to a shop?

Also I searched old threads and saw people asking about the special tools to remove the seals and retaining rings (they look like dent pullers).

So questions are

  1. Do you do your own repairs
  2. Do you use the special tools?(I use reverse pliers and a rag)

And I guess i’ll throw in how long do you get in between seal kits as from what I understand it is the single most replaced kit in any pump.

General pumps are typically every 4 or 5 hundred hoursr. Udors usually are good for about 2500 hours. The couple of times it has happened in the field I’ve just put a spare pump on. Much easier and quicker. I’ve done them back at the shop. Usually they go to the landa shop at around 2500 for a pump rebuild. There are videos that make it easier but its a pain without the right tools

I take mine to a local guy. If the pump is old then I just replace it. I use cheap general pumps so they don’t cost as much to replace… Unlike IBS I don’t have the volume of work that he does so my pumps last several years. But I am big on preventive maintenance … Its a Navy Thing…

If I can get 400-500hrs out of a pump…and I can replace it for $650,why in the world would I want to spend half that amount to rebuild it? Remember…it is NOT NEW when it is rebuilt.

I would rebuild one pump…only to have an extra to use until I could get a new one to me.And, it would probably make more sense to just buy a new one to have on hand.

Depends on where you are in your business. Loss of production is costly. 400 hours is about 12 weeks of washing. If I had to replace packings or mess with 8 pumps that often I would go crazy with the amount of money I was losing. I’m with you on spare pumps. If a truck goes out of town it has a spare pump on it. Engines can be found most anywhere out of state.
