Gikfun 12V DC Dosing Pump Peristaltic Dosing Head with Connector For Arduino Aquarium Lab Analytic Diy AE1207

I am a systems integrator so naturally my pool control setup is pretty custom. I started researching to find a cheap pump to do the chlorine dosing into my pool.A lot of the ones that forums suggested were $300 and I could not justify that much expense.I decided to take a chance on this one and I'm glad I did! It has worked flawlessly. Instead of running into the discharge piping of the filter I run via a small silicon tube directly into the pool.This pump seems pretty accurate for dosing and repeatable. The rate mine runs at is ~20sec per oz. I don't care if it takes 15 minutes to feed the 47 oz I need to dose and it may actually be a benefit to allow the chlorine to circulate instead of dumping it all at once.Tldr: I am glad I used this pump. It has worked great and it was super cheap. I plan on buying a backup one for the next pool season.

Arrived promptly, in tact. Pump is very quite & seems to do very good. I pumped 1 gallon of water using a 10 foot tubing (way too much but only for testing). According to 100 ml/min flow rate it should take around 25 minutes to pump a gallon. Mine took about an hour but there were mishaps (tube not submersed for a while, etc.) so I think it should work about as specified without interruptions. Am using it for wine making so wondering if tubing OK (everything is known to the State of California to cause cancer!) and whether there is any duty cycle on the motor as making 5 gallons of wine would take about 2 1/2 hours, if all went perfect, which might strain the motor. Great for wine making as all one does is put tube on one end and little stub on other goes into empty jug and does not touch wine preventing contamination and slow rate of pump and small tubing orifice provides minimal disturbance of settled layer. After pump was done I smelled the motor and there was absolutely no burning smell as that is a tipoff that a motor might fail. Also the motor was warm but not unduly hot so it seems to be good. I Recommend this product.

This motor works exactly as it should l, it seems well made. However, the motor is a little slower, and louder than I was hoping for. This does not mean it is bad, it is still great. Just did not work for my project.

Alas, I destroyed it in a week, leaking a strong electrolyte solution into the DC Motor. NOT THE MAKERS FAULT! Mine only, ordered another TWO as backup right away. VERY VERY VERY impressed. In point of fact I had a "two phase" flow I was putting in the suction. As calculated, compared to a diaphragm or a centrifugal pump, THIS pump had no problem. It's NPSH was quite adequate for pulling the solution up a foot! And then it discharge into an overhead of about 12" of "water" without a problem. (People of technical background will find this information useful.)

Needed a replacement white ink circulation pumpfor my dtf printer this is a great substitute! I have had any issues.

Tested this out with a nalgene bottle pumping water from the bottle into a tea cup. At 12 Volts it was pulling about 0.35 Amps and didn't seem to be struggling moving the water through the tubing. Looking forward to automation of plant watering with this one.

The silicone tubing on all of my pumps cracked and leaked within 2 weeks of purchase.Thankfully my application is for nutrient water and the pump tubing is easy to replace otherwise I would be returning these and giving them a lower rating.At 12VDC, actual flow rate (with zero height climb) is closer to 60~70ml/min. Suction is powerful enough to maintain that flow rate with my setup of ~50mm height climb.Overall happy, I would just recommend buyers have spare 4mm OD / 2mm ID silicone tubing on hand. *Note I tried swapping with 4mm OD / 3mm ID silicone tubing and the motor does generate any noticeable suction.

I have this motor pulling liquid hand wash soap as part of a Science Fair project for my kid. It works perfectly with a 12v Battery and the soap dispensed is just perfect for my project.Tip: The tube used for aquarium air filter fits perfectly for this one! So visit a pet store and get the tube from there!! You will NOT find it in any hardware store.Few things I would ask for from the seller, that will make this the BEST.1. Can you put an arrow symbol to identify which way is in and which is out?2. Can you add instructions to change tubing. I know one can change the tube but havent found any instructions for that.
