12V DC DIY Peristaltic Liquid Pump Dosing Pump for Aquarium Lab Analytical 5~100 mL/min DP-385-100

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.

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

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

I'm not sure why the other reviewers had issues, but this thing runs like a top. It self primes, even with larger diameter hose added (primed as open loop first) and I'm running it off 12v 850 miliamp power with zero problems. Not sure on the life of it yet but fully plan to find out. All and all completely the money.

I used this for a homemade automatic liquid chlorine dispenser for my pool. I travel a lot, so I'm not always home to consistently add liquid chlorine into my pool, this works perfectly, but you need to frankenstein it a bit. In case anyone is wondering how my setup works: I bought this, a medium sized ammo box (although a small one would probably work too, I just wanted extra space), a 3mm ID x 5mm OD silicone tube, I already had a long outdoor extension cord, and some kind of timer (can be christmas light timer or something. although a timer with short time increments would be the best, like minutes if possible). You just need to connect the silicone tubes into the nipples that are already on the pump. You don't need to do anything to the pump. Then you just plug everything in, connect one end of the tube into a bottle of liquid chlorine and the other end straight into the pool. Set up the timer and leave it alone. That's it! The quality of the pump is fine, I haven't had it long so hopefully it works for a while. It's not noisy at all. The default power is more than enough for my use, I actually have the dial set to about 25%, it was pumping way too much at 50%+.
