Review on 🐠 Efficient Dosing Pump 12V Peristaltic for Aquarium Analytical Applications by Rovy Oppeneer

I've reached the maximum suction height of 15 feet. I would have checked above, but I didn't have enough drop height. The power source during testing was a 9 volt battery. Also tested with a 10 volt source and a 12 volt source both worked very well and both revved up. Amazing performance for the price. In experimental tests, it moved about 1-2 liters of water per hour. I used it continuously for about 3 hours. no problem. It's a little tricky to get started with the 9V power supply, but if it seems stuck and won't spin, just push it and it's on its way. You just need to heat the tube to make it easier to crush.
