JHCCoffee I donāt have an experience of an ARS pump, from a look on the internet it just looks another manufacturer of vibratory pump. I donāt see how this would be any different from a standard ULKA pump, or the OLAB silent pump you already have.
The silent pump does have slightly less power (35 vs 41W), but Iām not sure it makes much difference.
While I obviously canāt guarantee it, I canāt see how the dimmer mod could damage a vibe pump. The electricity is charging a coil which makes a magnet move and hence the attached piston. Should it destroy the pump (I canāt think how it could) its Ā£69 for a new one (obviously youād need to find one in Canada), so in the grand scheme of coffee paraphernalia itās not that much.
If I was you Iād stop theorising and just give the dimmer mod a go. As long as you donāt drill your case itās fully reversible. You could mock it up in a project box, obviously ensuring you take suitable precautions not to electrocute yourself. You should soon find out whether it works or not
