Lots of questions on grain air pump systems?

Somehow I am leaning towards the used system from custom built because this Steve guy seems very, very sharp on these systems but just wondering if anyone else on here has the sukup system or just wondering does anyone on here have any advice or questions that I should be asking these guys because I have never been around a pnuematic system at all.
Thanks for any comments

The remains from 5% broken kernals make it much harder to cool the center of bins, making it a necessity to core the bins as soon as possible.
I would consider the pressure switch a necessity. Remember an air system is much like a water pump. Closer to the grain source the better it works.
I would much rather have 2-10 hp motors starting in sequence as 1-15 hp motor starting at close to full load. As a huge added bonus, motor life could be expected to be much longer, probably limited by life of the bearings.
Doubt one could expect Steve to be much cheaper than a factory built unit, as best and cheap seldom occur at the same time.

Control Panel is probably not necessary as the Sukup panel does not really "control" that much. You really could wire the system up to a few breakers directly and it would work okay. I assume that is something how Custom Built would do it.
We do not have an air bypass like you are talking about. We do have a gate valve which can be adjusted to allow some air to bleed off which would slow down the speed of the grain and reduce damage. We do not use it. We just let her run full blast as I would rather have a little more grain damage versus plugging the thing up. We do have cyclones. We do get a fair amount of FM but we have never been docked because of it at either West-Con or Poet Big Stone. I should mention that before we put this system in we had a shivvers dryer with roof augers. So we had grain with almost zero FM. We put in a continuous flow dryer and the air system in 2003 and our FM did increase noticeably. But I'm not sure how much has to do with the higher temps. of the continuous flow dryer and how much has to do with the air system. A couple of years ago we filled one entire bin with 16% corn from the field. It did not pass through the dryer but did go through the air system. If I remember correctly the FM seemed to be pretty minimal. Biggest issue with the FM is to make sure and core the bin after filling in the fall.
Piping should be fine either way as it is the elbows that wear. We have not replaced any of our elbows yet and we have about 1.2 million bushels through the air system. Actually have done zero repairs to the air system since installed.
We have never plugged our system so the pressure switch shut off thing might not be necessary??? We have a 30 HP three phase motor although I think the recommended motor was 20 HP. Wasn't much price difference going from 20 to 30 so said what the heck. Our farthest run is about 170 feet horizontal and 60 feet vertical and it can still handle our 20 foot dryer pretty easily although we will get really close to maxxing out the motor amps if we are only taking about 5 points out.
Hope this helps and good luck with your decision. Getting rid of the roof augers is one of the best things we did around here.
Water pump as air pump or vacuum pump
To shock every body: YES YOU CAN USE WATER PUMP TO PUMP AIR OR TO VACUUM.
The key is your pump needs to have water in its chamber of the propeller only.so you can use some tools that maintain the water there so you can suck air or in my usage acids and alkali material INDIRECTLY but efficiently. They are called priming tools.
The centrifugal pump works when the propeller is in liquids like water. So if you just make the housing full it can prime it self.
Then if you want bigger volumes of air to be sucked or pushed you can use a sealed container as the liquid storage. Search for self priming pump principles Then search liquid ring vacuum pump and compressors.
For more information, please visit aodd pumps manufacturer.
