I have not seen where they recommend anything but there own. It would sure be nice if they would make their propriatory pump available for purchase affordably as a single item. As a comparison, I have ebikes that have propriatory batteries to operate. I don't have to buy the entire bike again if the battery needs replacement, for whatever reason. I can just buy a battery from Blix. Maybe this experience will encourage them to do that. Kimo, have you heard of or looked into non-protein based foaming agents, synthetic ones? Such as Aerix Industries' Aerlite or Allied Foam Tech? No collapsing there! I'm communicating with them, hoping I can purchase a small amount for our use, although they normally deal with huge quantities for major industrial projects. https://aerixindustries.com/products/

Okay, so for any who ever have a pump problem... Tracy at Aquatec is awesome. She contacted Victoria at Precision Installation Products, the Aquatec distributor that Domegaia purchased these propriatory pumps from. I'm shipping the pump back to the distributor and they will arrange a repair or replacement from Aquatec. There is a 1 year warranty and the manufacturing date is actually on the pump, along with the necessary model and serial numbers. These pumps can only be bought through Domegaia. Not even the distributor can sell one to you, although Victoria is going to contact Domegaia and relay a request to purchase a backup pump, to help us keep production going through a tough time like this in the future. Thanks for your input in all this, Kimo. I'll let you know if Cement All is a feasible product for aircrete. It's an awesome material aside from this use, hopefully it's good for this application as well, if a recipe can be figured.

@kimo Probably where this is heading, but they would be the distributor that actually purchased the pump and has a "receipt" for it, especially if it is a special unit made particularly for them. I don't think there is any way that Aquatec is going to work with me, having zero data, no purchase history to provide. I really need Domegaia to respond to me and help wherever they can. Worse case, sell me another pump if it can't be accessed anywhere else. I can't imagine that I am the first customer ever with a bad pump.

Right, agreed. And I am a bit worried about it. It appears from another thread that he says they have Aquatec custom make that spec'ed pump just for them, which explains why we can't find it. I can't afford to purchase an entire new Little Dragon system from them, parts apparently can't be purchased, they don't seem to want to talk to me about my supposed "warranty" (I've tried writing @hajjargibran )...what is a guy to do? The pump lasted less than a week and was super suspect from jump, regularly stalling foam production for no apparent reason. Usually, running clear water through would get her going again, but eventually she just jammed and was done. I think that magnet was always cracked and finally gave up. $500 paperweight and no more Aircrete. I was desperate, so I thought I would try the closet thing I could get. It looks like the new pump I ordered is actually max 60psi! I'm going to cancel. What would you do in my spot?

@kimo Thanks, brother. Super helpful. I was just about to try my test with Cement All last night and the little dragon pump jammed... it's toast. Magnet around the copper coil is cracked and broken. Nice.
I'm pretty sure the cement all is going to work well. They have a set time increasing additive as well as a thinning flow additive and they work well with the product. Add foam and a lightweight, strong and fast curing product should be the result. Expensive, sure...but when you're making furniture, who cares. I'm normally buying 6 dollar a board foot Black Walnut for my designs.
I ordered a new pump this morning, but it looks like they have the little dragon one made just for them, and I can't see how to buy another from them. The one I ordered should be the same only with a max psi of 70, not 90. Should be alright as 70 is where we seem to be in our Drexel foam production.

Any input on this? Thank you again, Kimo, for your expertise.

I was using my little dragon for only the 4th or 5th time tonight and the pump suddenly jammed and stopped just as we were about to begin mixing. 30 bucks of crete in the garbage, but more importantly, my pump. I unscrewed the end and the magnet around the copper was cracked! It's completely broken. It is claimed in this forum that these pumps were chosen for several reasons, including it's 1year warranty. How would I go about claiming my warranty and replacement. I purchased your kit with the the pump included, not from the manufacturer or a dealer. You purchased it. What can be done?

@kimo How do you measure that, how do you know your gallon of water is getting you 10 in foam? Are you using the little dragon and mixing inline, as the foam is produced, or do you produce the foam into a 10 gallon total and pour it into the cement mixture, and blend?

My wife and I are getting amazing foam with the Drexel but it is frustrating as we blend with the cement mixture. There is a point where we are trying to pump the foam in to get the recommended quantity for a bag of cement, but it won't quite get there. It seems to start to collapse while mixing, especially when trying to finish up the mixing by blending some surface remnant foam in, while not infusing fresh foam. Just plummets.

You're right, the tiniest adjustments in air pressure drastically change the weight. I feel like the "shaving cream" like foam I am most proud of weighs only 2oz/qt or so , not the recommended 3oz/qt. So we keep adjusting until the weight is right, but that foam is less thick, more watery.

The foam itself, you can see it separates to water some in a clear bucket and does some collapsing in a relatively short time. Maybe this foam quality is why my experience is so bad when blending into cement. We just can't get a batch that resembles the lightweight but dense concrete we want...all are far too airous and brittle. You can poke your finger right into it after several cure days.

What do you mean by sand/topping mix? What was your recipe and results, brittle and crumbly?

Has anyone tried using Rapid Set's Cement All or Mortar Mix in place of Portland 94?
I wonder if the ultra quick cure time and fast high psi hardening could help with foam collapsing challenges.
Anyone tried it? Or even using it in a split mixture with Portland? If not, I may give it a go tomorrow.
