Very noisy osmolator pump

[sean_nj]

Hi,

I bought this osmolator last October. I just noticed recently that the pump becomes very noisy when it is switched on. It's much much more noisy than the MAK-4 pump. I checked the pump and it's very clean.

Do you know if there is any way I can fix it?

Thanks,

sean

Make sure it is suspended and not touching the bucket. You can also wrap it with a piece of mattress foam or general upholstery foam, just don't cover the intake. Running at 12V increases the noise over 9V.
