As the title states: I don’t have a titan, but do have a couple double holed geysers I’m trying to use for a couple machines. Followed a thread in here and bought a compressor off eBay. Wasn’t strong enough. Gotta send it back. I went to pet store and got a bubbler intended for a 40gal tank, still no bueno.
What can I use for the double heads that won’t cost as much as the one on the DP titan (which costs $300+). I know you smart guys must know!

Given our conversation, I ran some numbers, broseph82 , and compared my Medo pump (single DP geyser) with wigglinrocks ' aquarium pump. Based on the eBay listing, his pump puts out 794 GPH. That's about 2.25 times greater than the output of my Medo, so it makes perfect sense that it would work just fine for your dual geyser need.

lol. Good thing its for just air pressure and not for anything submersible. I'd hate to have to fill the damn thing.

Who makes your geysers? A genie geyser won't work on an aquarium pump. I have a one hole brass geyser similar to what Johnson Brothers has for $15. I have two other brass geysers that don't work as well. I put 3 geysers under a wheel and when my JB order arrives I'll see how two work. I have 8" wheels.
The Genie pump goes put, put, put. My Genie pump belt broke. My left side wheels are frozen and I'm in no hurry to deal with it so I use my aquarium pumps on by stardiamond and Genie. I use drip a watering T and wider aquarium tube to connect both bubblers. I tried using the narrower aquarium tube from the genie geyser to the aquarium pump and nothing happened. When I used my genie geysers on the genie, I would use both on a wheel. The genie geyser system produces more water than my set up.

Geysers are venturi pumps. Venturi pumps produce very fast moving air which, in turn, creates a vacuum that pulls water up and out onto the cutting wheels. Pump air pressure is really not all that important. What is important is the volume of air that the pump produces.
(All other things equal) more air = higher velocity through the geyser = greater vacuum = more water moving faster and farther up onto the cutting wheels.
At least for a single Diamond Pacific geyser, from my experience the pump needs to put out air in the range of 0.6 to 0.7 cubic feet per minute, or about 270 to 315 cubic feet per hour.

The spec for the pump I bought is 1.3 liters a minute.
The whisper 100 for $22.79 puts out 3.3 liters a minute.
28.31 liters per cubic foot.

And both work well? I am less sure of what minimum air volumes per minute are considered acceptable for a given geyser.
My AC0201A Medo, spec'd at 20 liters per minute, is about the maximum anyone would want with a DP geyser. It throws up a good spray of water.

Your information was very helpful. I ordered a whisper 100 and will see how it works with a JB bubbler. I thought the JB with a center hole was better than the others with a front hole, but I was splitting the others off the same pump. I like a lot of water when grinding.

My whisper 100 arrived today. It is twice as big as what I have now and has two air outputs. For now it would mean that I would only need to use one pump for two heads. I have a tee connection that split the air to two heads I will contact the manufacturer to see if I can reverse the tee, so two connections to one head. Since it is designed for two outputs, I don't want to overload it with a merge.

according to the manufacturer I can reverse the tee where all the air would go to one geyser. I'll see if it makes a difference tomorrow.

One air hole from compressor but am using this to split: imgur.com/gallery/mMpN43gAnd no, this isn’t the final form of the hookup. I’m actually moving into a commercial art studio (hopefully within the week) and just wanted to see how well my rig would work
