My manual only shows a pump assy, and no details about it so you may need to contact 3S.
Yes, they are three-phase 240. I decided after hearing the horror stories of coolant growing bacteria in sumps that I wasn't going to use the sump in my machine (plus I didn't want to try and get it all the sediment loosened up and washed out), and so I bought a MicroDrop for general use, and one of those 5 gallon tanks with pumps in case I ever want to sling flood coolant all over the shop.
cheers,
