DIANN 2pcs Mini Submersible Water Pump DC 12V Micro Water Pump 840L/H High Flow Pumps for Aquarium Fish Tank Fountain

Really good. But way to much flow. I use it with a voltage controller to reduce flow for my fountain.

I did a little study with one of the pumps I just received. You can see the power consumption and open output "head" on for the pump, to determine if it's right for your application. I didn't have a clear 1/2" pipe to connect and do a proper head test, but this should give you some indication of what it's capable of at different voltages. Note, the wires are SUPER thin, so just stripping insulation and crimping something on is a little difficult. It's also important to note that the listing states "Don't Use Continuously 24 Hours." If you are depending on this to run constantly, get something else. I'm designing this into a piece of DIY medical equipment, so I don't need continuous operation, and with the deal of getting two pumps, I've even got a backup.

I use this pump in saltwater on my kayak. I fish at least 2 to 3 times a week in sometimes rough ocean swells and water often gets in through the covers or hatch. This pump drains water with no problem using a separate battery from my fish finder. Sometimes I may drain 5-7 gallons of salt water in a single trip. I did have the motor or fin seize up on me but realized that I ahould run some fresh water through it once in awhile as salt water will seize or corrode everything at some point.

Used it to replace inop flush pump in my Aliner LXE. It is ŵorking great and is quiet. I took the Aliner to Washington state from Phoenix AZ and back with no issues and just returned from 3 weeks camped on the Mongollon Rim.

There is not connection pin on it it is naked wire you need to connect electricity

Works great thank you

Great replacement for my water system in my vanagon. Nice pressure

Purchased these as for replacement in a Thetford cassette porta potty. Exact fit. The original pump lasted something like 15 years of light/occasional use. When it went out, I had a dealer replace it for around $120. It lasted 10-15 years and went out again. I purchased this type pump about 5 years ago under another mfg name, but pretty sure it is the same as these units. That unit from 5 years ago went out and I purchased this 2 pack for $15-$20 and works fine on the one outing so far. A OEM pump is about $50 as a diy. Even if these only last the ~5 years it’s a good deal . If used in a high use application, may want to upgrade to an OEM unit. For the price, these are good.
