run speedwave 2640 without controller?

If you have a multimeter at home, it would be an idea to check the output of the power supply to confirm that it's providing 24 volts. Alternatively, you could connect a couple of car batteries in series to act as a 24 volt DC supply & hook that to your controller. This would at least confirm which component is unserviceable, the power supply or the controller.

Without any kind of schematic, it's near impossible to troubleshoot any further than that. I assume that the pump itself could be run on a straight DC signal, anywhere from 12 to 24 volts should get it kickstarted, but that's just a guess without any further data or schematics. The green/yellow wire to the pump is very likely a safety ground, but could also be a signal wire for control. Without confirming it's function, probably not a good idea to hook it directly to a DC supply.
