Subject: Procon Pump shows rust. Won't rotate easily
 

My La Pavoni Pub1M recently stopped providing pressure. Opening it up, I discovered that the pump itself would not rotate easily; the motor rotates with no resistance. There's rust at the spindle (see attached picture).

I can replace the pump for $133 at EspressoParts.com, but I'm wondering if this a repairable job. The orginal Procon is a 100L pump; the EspressoParts pump is a Hydropure with 264L/hr capacity. Any suggestions? Will the Hydropure be significantly louder?

Thanks,
Phil

For the most part, the pumps are more similar than they are different, it should work.
Check a few different makes just to know what the market is, so you will be more comfortable with any purchase you make.

Thanks. I do plan to look around as well. Any thoughts as so whether I could fix the old one, though? I read that vinegar might help against the rust, so it's sitting in a vinegar bath right now (just the spindle end, not the entire thing). But I'm wondering about the point of emanation for the rust. I'm not sure how old this machine is or if the pump is original. I'm wondering why there's rust there to begin with...

That pump is shot, there is a seal inside that is obviously leaking or has been - Usually find this after a machine has been stored for a while in cold conditions such as a shed or cellar.

Even if you get it to spin freely it will leak.

My guess is that the pump is shot.
When I bought my machine, the pump was frozen but it did not have a trace of leaking and it had been sitting without use for a few years so the pump stuck. I took the pump off the motor and used a wrench to get it moving which only took a slight movement of the pump shaft, once it was loose again it has been fine since.

Yours shows leaking AND it stopped / slowed while in use, my best feeling on it is that it is time for a new head.

That's my suspicion, too. It's one thing to "repair" it but if the leak continues, then it's just a matter of time.

Well, thanks for the tips. I'll start looking for a replacement.

Another option is to have your pump rebuilt by JC Beverage.
I haven't used them but have read the cost is around $35 + shipping.

Thanks, Dan. As it turned out, I also discovered this option, except I found EDCO Service Center in California for about the same cost. I just shipped my pump to them for analysis. Hope to get it back in less than two weeks.

Update for anyone interested. I did get the pump back and it looked like new. Installed easily and has been running beautifully ever since. I do notice it's a bit louder, but not as if it were straining so I'm not sure why. It's not disturbing (to me), so I'm happy to have a well-functioning machine again.

Thanks for any tips and suggestions.
