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

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 wanted to get a cheap peristaltic pump, which can pump water with flow rates 0.1 to 5 ml/min. The minimum flow rate of the INTLLAB Peristaltic Liquid Pump with 2mm ID x 4mm OD is too high for my purpose, so I have tried to decrease it by (1) using tubings with smaller ID, and (2) supplying the pump with lower voltage.Hooshing Silicone Tubing 1mm ID x 3mm OD (ASIN: B08QFFLP3S) were fitted into the pump head without problems but would easily slide out upon running because the OD is too small. I used MettleAir 129PP-1 Polypropylene Plastic 1/16" ID Hose Barb Union (ASIN: B00S529L6Y) to keep the tubing in place, and it works just great as if it was intentionally designed for this unit.Also, I replaced the original power supply (outputs fixed 12 VDC) with SHNITPWR 24W AC Adapter 3V~12V 2A Universal Power Adapter (ASIN: B08YN79VVD). At lowest voltage input, 3V, the pump starts to operate when the flow control knob reaches the middle of its range, and at 4V it can move in the entire range of knob positions.With 1mm ID tubing and 4V input voltage, it was possible to get a sustained flow rate as low as ~ 0.4 ml/min.

Edit: The pump broke after about a week of operation.So first off, I can't believe I got a peristaltic pump for this cheap. It does work, but barely. I just needed something to barely work, though, so it's fine. (I'm regenerating SPE cartridges in my lab with HCl, so I just needed something that can handle acids and that will move fluid at any old rate). The rollers are turned by nothing but friction with the shaft of the motor, which means that if anything changes this amount of friction you will not have reliable pumping speeds. This also means that you can't put vacuum grease on the rollers, which usually key to maintaining the longevity of peristaltic pump tubing. So I don't know what effect this is going to have long-term on pump performance. Also, there's no reverse, but I added a dpdt switch to switch the polarity of the motor and it works in reverse now just fine. Anyway, I would not trust this AT ALL for precise metering, but if you need to move fluids that require isolation from the pump, this works.

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 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.

Quisiera que tuviera menos presión para regular niveles más bajos pero igual me sirvió perfectamenteLo que es un poco complicado es encontrar mangueras

This review based on build quality as I didn't have the chance to fully test this dosing pump on a long run.So far all what I can say this pump is built like the original Nokia 3310 lol. The casing is made from very high quality plastic and it doesn't feel cheap at all, I would say the case and the motor controller alone worth the money. The pump head and Probably the motor it self made from cheap material.I ran it for 1 hour to test, the dosing is consistent . I'll make another review after I try it on my calcium reactor.*******Updated. The peristaltic tube head is very poor quality, I end up modifying this dosing pump by replacing the whole pump with high end motor and peristaltic head. As I said previously the only good part about this pump is the housing and the chip. If you're into diy and willing to do some modification like me then yes the price is fare, otherwise save your money and get something ready out of the box.

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.

arrived on time. Planning to create a large format 3d powder printer for sculptures. Unit works exactly as I expected.
