This should work with any of Tunze's ATO systems. The 5017 is just one component of the Osmolator 3155 system so it is a direct replacement to the pump included.
Hope this helps!
Have a great day :)
(fresh water discus setup) this unit will be set up in a sump
Great question, The Tunze replacement pump is only currently designed for use with the Osmolator controller. For alternative pumps we recommend looking into standard small return pumps such as the Sicce 1.5 which has a head height of 6' and could just push the water over the side of a 5' tank. Feel free to let us know if you have any further questions!
A small check valve could help in addition to increasing the speed of the pump if possible. You will want to look into adjusting the pump settings to increase the dosage. Feel free to let us know if you have any further questions!
The Pump has a varying GPH rating depending on the head height. Its maximum head height is around 8 feet. and it has a GPH rating of up to 15 GPH.
the Diameter of the pump is 2"
Its smaller then a pop can. A 6" hole will be no issue at all :-)

Works Great.. By Joseph on 3/19/2017Joseph would recommend this product to a friendI was having Issues with the old pump. They new one works so well. I hope I get another 3 years from this one. :)
Works but you need to read the directions By Kecked on 2/25/2017Kecked would recommend this product to a friendThis unit is designed for smaller tanks. It is designed to shutoff after a period of time regardless of the float to protect from over filling a small tank. That's why you had to unplug it and turn back on. There is a jumper to stop that. See manual. Ps it also will save your pump from dry running.
Excellent System By Huck on 12/28/2016Huck would recommend this product to a friendI have been running my TUNZE ATO system for about 4 years. I started out with a 50 Gal reef adn after two years upgraded to a 125 gal reef, and the TUNZE ATO has run through the transition flawlessly. I purchased a spare pump when I purchased the system 4 years ago, and it is still in the packaging unopened. My original pump is still in service. I did run into a small problem after two years of service, as I used kalk in my makeup water, and the pump stopped working. I simply placed in a distilled vinegar/RO water solution and let it stand for a few days, and then the pump started working again. Kalk will definitely reduce the life span of pump as it was not designed to pump a pastey Kalk solution. I upgraded to dosing 2 part and removed Kalk from my system altogether. If this unit is running strictly RO water it will last. for a long time.
Just in case!! By Badabing on 10/17/2016Badabing would recommend this product to a friendI'm replacing my three year old pump, it still works but it's starting to make alittle more noise so for $20 I'm changing it and keep the other for a spare, never a problem with this ato!!!
Quality at a great price. Always have a spare By Fred on 9/14/2016Fred would recommend this product to a friendThe Tunze ATO is the best ATO on the market and it's always good to have a spare pump on hand, because for the price, you ant afford not to.
All around quality and easy to swap out/install. Small, quiet pump but still really strong.
When you need to replace your Osmolator pump ... By Larry on 4/25/2016Larry would recommend this product to a friendThis is a cheap, easy replacement.
Good experience despite what some other people have said. By Seanj on 3/16/2016Seanj would recommend this product to a friendI'm still on my first pump that came with my osmolator, and it's been running for almost a year sucking kalk probably everyday in pretty much the most extreme situation possible for an ATO pump. I will happily buy a replacement before it quits just to have it on hand.
Great product! By dallast on 12/8/2015dallast would recommend this product to a friendBought ato on EBay, so when pump failed I was out of luck with tunze directly. Customer service at tunze was fantastic through reef2reef forum. I'm quite sure had I purchased new, he would have just sent me a new pump immediately.
I love this ato and I am not sure how I lived without it for so many years.
great stuff By reefer matt on 12/7/2015reefer matt would recommend this product to a friendI decided to buy this as a back up. My original one is still kickin after 4+ years .
Great! By Philip on 12/7/2015Philip would recommend this product to a friendPump is super quiet an real easy to set up.....just using with ato not dosing so it works awesome
Burn out By Bill on 8/17/2015Bill wouldn't recommend this product to a friendI ordered one of these after my first pump quit around month 2. Now this one has quit as well in less than 2 months. I love the ATO but these pumps are junk.
Nice; when it works By Gary Gipson on 7/23/2015Gary Gipson would recommend this product to a friendThe only weak link in the whole TUNZE system. TUNZE osmolator is the absolute best and reliable ATO system out there which is the only reason I put up with the pump that is less than desirable as far as reliability. If they fix this issue, they will own the ATO market.
