Exactly. Loop flows clockwise in the pic.
One challenge to note, the way the pump is mounted it doesn't want to prime from the BK on its own but if you open the valve, push water through the pump with an autosiphon, and then close the valve on the pump outlet before hooking it up it works like a champ.
