Its Aqua-Aquarium brand, and it can be hooked directly into the sump if you use a float valve....Last two he had sold for $74.50 with about a $27 shipping fee, so its right around a hundred bucks. He always has them advertised on that "well known auction site" I tried to post that name in the first post but it got blanked out........do a seach on that auction site for aquasafesystems. If you add a pressure tank or pump then it can be hooked up to a ice maker, other than that a pump is not needed for aquarium use. Just use a needle piercing valve or hook it up to a faucet and start making your water. A pump can be had for about $65 if wanted and a faucet hookup adapter is something like $5.00 I just checked and there s a heap of them listed, along with a pressure tank as well as without a pressure tank, starting at 99 cents or some with buy it now prices......anyway they are a great unit, and hard to beat for the price, which is about 300 dollars less than my LFS sells the almost same exact thing for.
