Now I need to find out how they stand up to constantly turning on and off.

I did find a 2" solenoid w/valve on the 'net, for a measly $2200.00.

Yeah that will be your best bet. Turning on and off with the duty cycle you're proposing will be fine. The pumps are basically the same as those used in hot tubs which turn on and off way more than that.

Yeah and don't forget to multiple that number by at least 4 as that's the minimum number you'll need for the system if running a single pump. OM may do custom work as well but I can't see how one of those systems, customized or not, will work for you. They just use timing motors to rotate drums and syncing a bunch of them to work together the way you want will be impossible. Unless you had a common suction and two different outputs on each side of the tank with a drum that rotates to the two outputs. You'll still need some kind of timer to turn the motor on and off to provide the pattern you're looking for and to get it right it will also need limit switches to keep track of the drum position. Even if OM would do this the cost would be way more than $500.
