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)

Great products and service

The pump works great with the kalkwasser reactor that is sold by Avast, just make sure you use the check valve provided.

Ato

No instructions included but overall easy to install pump strong enough to pull water to ft. And keeps water within quarter inch.

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
