As far as I know Diamond Pacific is the only company that uses under wheel geysers for cooling. A lot of people are worried about wheel contamination from using a recycled water supply. I've used a Genie for over 15 years without having an issue. I moved one tray to my stardiamond machine which I am using for 600 and 1200 Nova, so I add water to that tray as needed. I use the same tray on the Genie for everything through 325 soft and move it left and right. When it is time to pre-polish and polish with the wheels, I empty, clean the tray and add fresh water with an additive. When I am ready to use the end lap to polish, I move the tray to the left side and reuse the water for the next batch. My Genie pump belt broke and my left side wheels were frozen for a while, so I bought another aquarium pump with two outlets. When the left side unfroze, I didn't bother to fix the belt.
I found that the more water the better for the wheels and don't see any benefit from overhead drippers. What am I missing?
If I were going to design a cabbing machine, I would end up with the Genie design with removeable adapters to allow for easy wheel change.

I have only used geysers but have thought about converting to an in tray pump system for more water to the wheels and better coverage with my Genie as it only has the one geyser. My Titan has 2, two hole geysers that works better but still think the pump idea would work better.
Another reason I would like to go with the submersible pump is no diaphragms (leather) to oil, or pumps to take apart to replace the leather. Tiny submersible pumps are only about $6, a whole lot cheaper than the leathers, and so much easier to change out.

There shouldn't be any grit contamination from a DP geyser provided that nothing is partially clogging its vent. The venturi pump action effectively scrubs its water spray of any particulate. Using wetting agent may also help.

I have used a DP Titan since about 1985 and within the last few years moved to a fish tank pump. I have never had any wheel contamination that I can tell. Though I have to admit it seems like it should. I use some DP Nova wheels on some old Beacon Star 8" arbors and the issue there is getting a uniform drip across the face of the wheel. I have used a slice out of a 2 liter pop bottle to spread the drip out.

I am self-taught so I experiment. What I learned was, more water provides better cutting and a wetting agent helps with cutting. A wetting agent is better suited or can only be used with a recirculating system.
Geysers and use of a wetting agent vs overhead drip is like a political divide. The only issue with the Genie is pump maintenance and I don't use the Genie geysers anymore.

I have a Genie, but most of my preforms are shaped and domed on a Graves cabmate with a 80 grit textured wheel and plenty of fresh water. With that I can cut a lot of cabs without dumping and refilling the left side tray all the time. I would really like to make my own 6 wheel fresh water unit with more space between the wheels and switch the Genie to 4 Nova wheels at finer grits, like 1200/3000/14000/50000 and polish with it. With fresh water the important thing is to use a bit of generic scitch brite as a spreader to keep the wheel wet with less water and minimize spray. The Cabmate also has a 2 speed motor, with softer or brittle materials the slow speed is nice.

Any way to power the geyser besides the genie pump? Switching to a drip system any thoughts on a good pump.

I use a Medo pump purchased on eBay. But many people are happy with aquarium pumps. The important pump spec for a geyser is cubic feet per minute (cfm) of air, not pressure (psig or kPa). My pump is spec'd at 0.71 cfm, and I consider that an acceptable minimum.
