Diaphragm Pump

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.

Diaphragm pump kit includes:

  • Pump in wall-mountable box
  • 24v DC Power Supply or 5' cable with Neptune compatible 24v plug 
  • Tubing, 10ft
  • Check valve to prevent back siphoning
  • Micro ball valve to adjust flow rate (max 400mL/min)
  • Siphon break tee (see instruction manual for details when this is needed)

Diaphragm Pump

The pump definitely over exceeded my expectations! The pump is a little noisy, but not bearable!

Quiet and Strong

This is my second of these units, the first still runs quiet and moves water after several years of use. Both have worked ad advertised and I wouldn’t hesitate to recommend them to anybody needing the capability these provide.

Powerful small pump

I am using this pump to pump the R/O water from basement to ground floor, so noise is not a issue

Loving it. I have installed

Loving it. I have installed this pump in my first floor with a rodi line connecting to my rodi water in basement 25ft across and 10ft below. It pulls the water within any issue and keep my ATO container topped up all the time. It’s so silent that when it’s on I have to touch it to feel it lol..

ATO pump

Works great. My ATO reservoir is a long distance from my display, but this pump has no problem making the distance.
