12V DC DIY Peristaltic Liquid Pump Dosing Pump for Aquarium Lab Analytical 3mm ID x 5mm OD

Great value for the money! I just finished calibrating 3 of 4 pumps. I was expecting a flow rate of 100ml/min and here are the results Pump 1: 82ml/min Pump 2: 102ml/min Pump 3: 99ml/min Overall, I’m impressed and happy with the results. I’m not a huge fan of the design, but I did manage to get 4 of them to sit inside of a 3D printed custom box very neatly. So, no big deal.

I use a Jebao dosing pump for my aquarium. One of the heads stopped working so I bought this as a replacement. Super easy swap. The only thing I had to do was solder the power wires from the old jebao head on to the new power spades.

Update: I did have one pump exhibit the black residue some have mentioned and it began slipping. I took a jewelers file to the motor shaft and roughed it a bit to help it get some grip again. The other 3 have been well.. but they only get used half as much as the pump for detergent. Bought this set to make a home laundry detergent/additive metering device. Having used one at work, I priced the commercial units and the prices were unreal. The pumps do not move a large amount in a short time.. which in a home environment.. is a good thing..(users less likely to hit the button again to pump more!) Each pump delivers at a slightly smaller/larger volume with the same voltage.. I used a 12v 1amp power block along with smart switch that only allow one pump to run at a time. The pump delivers about the recommended amount of detergent 1/2 cup, in about 2 minutes. After designing the unit I discovered that we, like most use to much of all the laundry detergents/additives.. So this pumps have ALREADY paid for itself in saving on the chemicals. Other users have noted debris and other issues with the pump, however I have not noticed any abnormal/discolored debris in the pumps; I have had them apart 2x to check. But it should be noted my pumps only get used about once a day, 2-3 days during the week for detergent.

I got this to build a DIY auto top off for my reef tank. I hooked it up to a wall wort 9v power supply and a float switch. It has been working flawlessly and would recommend this to anyone looking to do the same.

Excelente, cumple su función muy bien

I got this on time and in well protected packaging. I hooked up the pump to a power supply and turned it up to 12V. The motor turned on but the inner rollers didn't move around until I played with it a little bit. The white housing that holds the tubing flexes a fair amount, so I'm not sure how great a seal is being put on the inside of the tubing. I took one tube end and put it in some water to test it, but nothing happened. Nothing was getting sucked up. After playing with it for a little bit, I decided it had been a waste of 10 dollars and figured I would kill it by turning the power supply up to 24V for a while. The motor began to really turn over, and suddenly it began to suck up water. I turned the power back down to 12V, and the motor worked like it should, sucking up water and spitting it out the other end of the tube. After this I was able to turn the motor down to a low RPM with it still working as it should. So, mine works now, but only after I overloaded it with a power supply. If you're looking for a cheap motor you aren't too invested in, this might work, but I would probably look elsewhere.

Good

I ordered this pump and it worked very well for three months and then developed a leak. I contacted the seller, but received no response. Given, the pump was quite inexpensive, but it seems that it should last longer than three months. Update: 1/10/2022 - It actually wears through the tubing about every three weeks in a fairly low use situation so I'm looking elsewhere for a pump that will last.

Awesome pump! I used it on an automated Christmas tree watering system I built. Works awesome and is nice and quiet. The tube it comes with is kinda mehh, but I'd expect you would change it out anyway. I did and it worked amazing.

Good quality, great price.

Works. Have tested it by running it continuously for an hour. No overheating. Note that conventional aquarium acylic airline tubing will not fit inside the pump cavity. However airline tubing will fit the nipples on the existing tubing. It's fairly fiddly to get the pump open to replace the tubing.

I use these for dosing Ph Up for a hydroponics tote by installing them into a hobby box (see picture). These are suitable for purpose as long as you are comfortable removing the head and re-aligning the tubing around the shaft cams. Of two, I was able to make one work, but not the other, and had to return one. Think of these as disposable and make sure you have an extra on hand. Don't forget to run the feed line higher than your pump head so you do not create a siphon when you don't want to.

Overall, the pump works when you juice it with enough power, but it took me a long time to realize why it occasionally wouldn't power on. The motor gets jammed in the pump head and the head has to be removed before the motor will start spinning again. The motor itself has no problems.
