Central coolant system.

We went through this when I moved the shop and ended up putting 3 fill stations around the shop with hose on a reel. Can reach everything you want and can go from row to row.
System won't have enough pressure to fill multiple machines at once anyways. We put a central RO unit with 500 gallon storage tank that runs our cleaning and coolant system.
 
Our solution to the bucket brigade is a blue plastic drum with a sump pump inside. Sump pump is connected to a manifold of ball valves that then has pvc piping across the ceiling running to each machine. When running pvc we tried our best to slope it downward so all coolant drains to the machine.

The procedute is to add however much coolant or water you need to the drum. Open the valve to your machine and turn on the pump.

Still to do.... level sensors and solenoid valves to auto fill specific volumes. Then need to auto turn on the pump, and to replace ball valves with more solenoids and have a push button at each machine.... one can dream.

I could see doing this with a 3 way valve and an air purge. Push all the coolant out of the lines and purge the "fill area"
