pump suggestion

I think the closed loop principal would apply.

I think a 1262 would be enough. I don't think it's critical that the flow through the chiller is exact. I think they specify the optimal flow for maximum efficiency, but it would be difficult to match it exactly.

The other thought that I had is that the recommended flow through the chiller probably has something to do with the internal temperature sensor. If you configure the set point a little lower on the chiller and use your Ranco, it might be fine to run with a lower flow rate.
