Peristaltic dosing Pump 12V Kamoer Variable Speed Small Water Pump with Pump Head for Lab Chemical Experiment，KCP PRO2 Norprene Tube:3.2mm×6.4mm，40-210ml/min，with Power Adapter

Great little pumps, used a couple to pump 120gpm of a semi viscous fluid

I like the metal construction, the visibility of the pump working, and flow rate of this pump. Purchased to dose chlorine into my above ground pool. Automated with Kasa smart plug, this pump will dispense 32oz in 12 min on low speed setting. Longevity is unclear at this point given time in operation, but am very happy so far. Good quality, good value

Works as it should, very quiet

I bought this to make a diy fertilizer dosing system for my planted aquarium. The minimum flow rate is as stated about 40ml/min. It seems reliable and works nicely. The tubing that gets squashed by rollers to move fluid (the definition of a peristaltic pump) will eventually wear out but it usually lasts a long time we use these type in my research lab. So this product is good especially for the price. I don’t think this type of pump is advised for continual use however. Best for intermittent applications

Really happy with my purchase, despite the fact that the tubing that was shown in the images was not included. I had to purchase that elsewhere.
