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. Please be aware this is not a silent pump, it does vibrate and makes a similar amount of noise as a typical aquarium air pump. It can also safely run dry, unlike conventional powerheads. It 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, it should also not be used with a float valve. 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.
