Verona Expres - noisy pump looking for a possibile fix?
just picked up a new (second hand) Verona Expres E61 coffee machine
it's very basic inside but in tip top shape with new pump and all seals replaced as well as custom steam wand and custom dials attached
only thing is the new pump is very noisy especially on startup, which I don't mind so much, but I will be using it for a few small catering jobs, such as the local tennis club, where quiet is expected especially during game play
any ideas how I could isolate the pump a bit to quieten it down ?
anyone have any tips on how to quieten down a noisy pump?
Is the noise from pump or from vibration between panels/parts
the vibration of the pump rattles the drip tray there is a bit of noise from the pump itself on startup but then it drops off after that
Quick google search found this, probably you just need some dampening material between chassis and driptray?
"only thing is the new pump is very noisy especially on startup, "
ASTG my E61 is the same. I tried chasing this thru a thread here a while ago.... to no avail
Im no expert with this, But I reckon the difference in noise level is due to -
On start up the Water Level in the Boiler is being replenished And on my machine it is a solid copper pipe
where as, upon brew activation the pump delivering via a flexible silicon tube as part of the brew path / opv.
See if the hands on techo's here respond with a yay or nay on this theory.
As to fixing it - Obv more (rubber) / better / renew the pump mounts And I was thinking of a S/S braided rubber pipe into the
boiler. But Im iffy on this as the heat reflection back out into the rubber pipe is a major concern.
Anyway my second crack. Hope it helps.
