    I believe that is very do able. Several folks have moved from gear pumps to air diaphragm pumps.

    Sure...just pull out your wallet. You'll need a compressor, air line filter, and a diaphragm pump capable of running the press.

    Look at the new cdl catalog. They offer air or electric diaphragm pump. I called the dealer a few weeks ago pricing just the electric dia. pump and asked them about it and they say said they have had a few demos out the past few years and they have had no issue with it yet and with electric you just plug it in instead of having the investment of stuff Dr. Tim listed off.

    Does anyone have experience with the electric diaphragm pumps? They would be more cost effective in the long run and It would be quieter than air (which is what we have right now) my only real concern would be the speed. Filtering is a pinch point we cant really afford to loose capacity on right now, but if I could trade that tick tick tick sound of the air diaphragm pump for a quiet eletic motor I would be happy.

    What size is your air diaphragm pump 1" or 1/2"? The electric pump is 1/2". I would assume the electric diaphragm would be like a shurflow pump used by smaller sap collecting or on an atv sprayer. The down side of new product, theres very little non biased reviews on whatever it is.

    I have the Smoky Lake SS filter press with air diaphragm which I like. It is heavy, heavy. I like the concept of clear plates; however, I am small enough that my press does stay hot once it's up to temp for a long time between filtering on longer boiling days.

    it is 1/2 inch right now. We usually run a higher PSI to get better flow out of it because it is a bit of a pinch point. I was hoping to get some reviews of the electric pump in terms of flow and reliability because the air pumps are loud and annoying. Most people revert to saying well you need a bigger press, but the westfab we use is reliable, and it would be nice to not have to shell out the money they are asking for a 15 inch press.

    Some pics of my Clear Press and air diaphragm pump. It came with 5 plates but seldom use more than 3.
    Biggest advantage of the clear press is being able to see what's going on inside.
