24v pump barrel connector

Hi guys! Trying to reconnect the ‘old’ brewpi pump which uses the potentiometer expansion board to operate. The board requires a 24v input via a barrel connector. I have a 24v output in my brew controller and could solder the connector to it. but need to know where the all the wires go - on the barrel connector, should the sleeve be positive or negative? Don’t want to ruin the pump…

Center is positive. The pump has protection against reverse and overvoltage.

It is a 2.1 mm barrel jack.

Thanks Elco! Enjoy your vacation.

The connectors I’m finding on the web are listed as 12V/5A. Would that be ok for the pump?

Yes. That should be fine.
