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 resultsPump 1: 82ml/minPump 2: 102ml/minPump 3: 99ml/minOverall, 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.

Good

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.

This does not work even out of box. I had it for a while and did the test which after that I find out this is not working. Complete waste of money and time.This is an online sale, and we have to be more careful because we put time, money and effort and when you get the stuff it is not working.I have to buy another one, but I am not going to be it from this seller at least.

I was looking for a variable pump. I presumed from the description that this one could be used to suit my purposes. I'm not sure what it takes to vary the output but 19-100 seems a bit aggressive. I'll be able to use it for . . . something - just not for my original intent. I'm not sure what the duty cycle is for the pump; I gave up on further testing once I found out the throughput wasn't up to the task.Don't get me wrong . . . the pump works fine for what it does. It spins. It hums. It pumps. Just . . . not enough for the task at hand.

Excelente, cumple su función muy bien

Unit works well and transfers liquids as intended. The quality of the supplied silicon hose is mediocre, as expected from a Chinese manufacturer/supplier. (Hose gets pinched by rollers and takes a long time to regain original shape)
