Diaphragm Pump
33
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 60psi (~130ft high). It can also safely run dry, unlike conventional powerheads. It is quiet and runs on 12v 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.

Great Pump
Quiet and moves water easily. I expected more of a trickle based on the size of the pump but it pushes a full 1/4" stream through the ATO hose. Paired with the ATO, tops the sump off in about 2-3 minutes. If you're right by the tank, you can hear it kick on but if you're more than 4 or 5 feet away, you can't even hear it. Very good pump....
Diaphragm pump ***amazing customer service***
Purchased avast’s diaphragm pump for my Ato the previous pump died on. Received order quickly and correctly, unfortunately unit didn’t work. Reached out to to Avast who immediately sent me a return label no questions asked. Then much to my delight received pump back in order a week in perfect working order. Unit functions flawlessly and blown away by the awesome customer service. Avast has a customer for life with me
