Diaphragm Pump
49
This little diaphragm pump is an excellent choice for automatic top-off duty. Unlike other diaphragm pumps available, this little powerhouse can push water to 30psi. It can also safely run dry, unlike conventional powerheads. It is quiet and runs on 24v DC power. Flow rate is approximately 400mL/min, but note that it is not rated for continuous duty nor salt water applications. This means for intermittent use (as in ATO usage) it is great, but we do not recommend it for use as a calcium reactor feed pump, for example. It can be used in conjunction with a kalk stirrer, but only to push fresh water into the stirrer. We do not recommend pulling kalkwasser through the pump, as the high pH may shorten the life of the rubber diaphragms.

Best Buy for ato pump
If you need more flow than the 2’ a Tom’s pump will give you go with this. It’s cheaper than the other commercial options, quieter, isn’t going to siphon, and got my ato water the 50’ across my basement when no other pump would
Diaphragm Pump
I bought 2 of this pump 1 month ago. It is easy to install and they are such a small and powerful pumps. I am using them for pumping R/O water from basement to my 2 tanks on ground floor. I can say that it is still too strong/powerful, but I am happy with them. I did not select 5 stars because one of them came broken. The motor was not attached to case, so it vibrates and makes a lot of noise. I live in Canada, and it is not easy to return it (I do not want to pay more fee/taxes). I fixed it my self and the noise is lower now. The good one works great and noise is not high.
