Subject: procon bypass valve spring
|
Hi,
The vibe pump and/or pump bypass valve on my Faema Compact is not
doing well. I'm considering converting to a rotary pump, since it
won't cost that much more, IF I can convert a used 151-250 psi model
from a carbonator pump to a 100-150 model. (9 bar is ~ 130 psi for
metrically-inclined readers.)
Procon says it's possible to replace the spring, but that it's not
recommended that *I* do it. Is it particularly difficult to seat the
spring and thread the bolt that holds it all together?
I didn't have any problems reassembling the bypass valve I'm using
now, but I don't know if the Procon bypass valve is particularly
tricky. (and would like to find out first)
Cheers,
-Paul

Piece of cake. The only minor problem is that sometimes the plunger
falls into the strainer screen and you have to fish it out.

Do you actually have to change the spring? I am also looking at a 250
psi Fluidotech pump. I emailed Fluidotech and they said I didn't need
to replace the spring, just to turn the screw a few turns. But there
are a lot more food-safe 250 psi Procons floating around than Fluidotech.
Thanks,

Loosening the adjustment screw may work, it depends on the spring's rate and
preload, and how much thread is available. Certainly worth a try!
