Does anybody make a evacuating or reversing dosing pump?

[PigFarmer]

Looking to drill holes in the top of a mini fridge so I can dose liquid foods....

Is there anybody aware of a doser that will 100% evacuate the lines each time or reverse backwards? so I don't have old food setting in the lines.... Thank you for any help!

@jasonrusso was talking about one not too long ago!

GHL doser do this from 2.0 onwards [emoji4]

I beleive the dos can be set up this way as well but u will need an apex

Thanks fellas! I don't know which 1 to go with.. I read both good and bad reviews of both of these options, lol

Are you asking whether the pump direction can be
reversed, or whether it can be programmed to do so automatically? The former is yes, not so sure about the latter. I’d consider using a diaphragm pump because they will back siphon.

Yes to both.
I used to use GHL doser to dose liquid feed at set times and used to use reverse to empty the tubing.
The thread is there in the DIY section, I stopped using the method as the wine chiller was guzzling up leccy

Apex is also capable of being programmed that way.

Alkatronic has that doser in their unit also
