Diaphragm Pump

Diaphragm Pump

$ 49.99

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.

Diaphragm pump kit includes:

  • Pump in wall-mountable box
  • 12v DC Power Supply
  • 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)

Technical Specs:
Max flow rate:  400mL/min @ 0ft head pressure
Min flow rate: Fast drip
Max head pressure: 60psi or 130ft
Run dry: Yes
Self priming: Yes
Power: 12v DC, 4w max, 2w min

Great product!!

I bought this to replace another popular brand of lifting pump. The pump I was replacing was only capable of barely a trickle at 24" of suction head. The Avast Marine pump easily provides the flow I need at this height and then some. Great product and wish I bought it sooner.

Excellent support

I had contacted multiple companies on a build I was doing and needed to be able to move water 100 ft, most said I could not do it. After my convesation with support, did it using the small diaphram pump. which now runs my auto water change (dirty removal/clean fill) and also using the same pump to run my remote ATO. Very clean and low maintenance install and would not have doen it without the help of the support team.
