INTLLAB DIY Peristaltic Liquid Pump Dosing Pump for Aquarium Lab Analytical

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%+.

Simple to snap the pump onto the housing for first time use. Connect two pieces of your airline tubing to the pump and plug it in-you're done. Purchased to acclimate new aquarium fish from the store water to the quarantine tank water at home. It was self-priming and pumped like a charm. Very satisfied.

I needed one that was programmable and not one that runs constantly. It worked good though.

These things are borderline garbage. For the price that's not a surprise, but they might be bad enough that even at that price they're surprisingly bad. At lower speeds (effectively the half of the speed/potentiometer range), they just don't work. The DC motor has too many dead spots, and even if it gets started it's liable to eventually get stuck and stop. That's regardless of taking it apart and trying to re-oil it and making sure the tubing isn't kinked and making sure it's attached soundly. So that rules out all the low range of the pump output. I haven't measured water volumes, but there's no way you're going to be able to pull 5ml with this thing, unless you get lucky that it dies at 5ml. You need it running fast enough that you can still have drips, but the drips aren't countable because they're coming out so fast. At higher powers, they do pump out water. They're very loud when doing so, but if you pull the pump head apart and/or play with how tight the tubing is in there and/or somehow push the pump head on really tightly, it can be quieter. Is it remarkable that technology and manufacturing is so advanced a little pump with controls can be bought for $15ish? Yes. Is this pump a quality device that you'll want to trust anything with, when you're not actively watching and controlling it? No. But it's cheap, and if you want some arbitrary amount of water moved at an arbitrary rate, with a decent ability to pull water up a height, while you baby sit it, it'll likely do that. I have no idea if the stand alone pumps without the case are any better.

Hello Vendor, Could you supply a TRULY battery powered rotary pump? From the description, it says "battery powered". However, it's only powered by the 24V DC converter. If you could manufacture the pump with battery compartment, we'll buy hundreds of that and use it in the field more easily.

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.

Mainly using this as an auto top off pump for my saltwater tank. Don’t know about self priming ability but it will pull from approximately 10 feet once primed (i helped it prime). Looking at design it should not lose prime or back siphon. Did general research on pumps of this style and generally they should pull from 35 feet. When you run into a situation where you need to get water from A-B, this thing will do it! I have a 58 gallon barrel of fresh rodi and i needed my ato to get water to my main tank a floor above it and this does it! Hopefully this thing will last a year! But how this will function for me, id say will run maybe a minute every hour or so depending on speed setting and evaporation! Some atos can run upwards of $50 minimum! Buy this and some hose needed for your setup and you’re good to go!

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.

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