KCP PRO2 High Flow Peristaltic Dosing Pump, 40-210ml/min Variable Speed 12V DC, Small for Lab Chemical Experiments with Norprene Tube & Power Adapter

Works for sulphur reactor. Doing 75ml/m

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

At minimum Water flows very unevenly. Any thicker then water it trickles even at the motor’s higest setting. Total garbage. Wasted money because i cant send it back now.

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

I'm using this in a fertigation system that I built. Since I am pushing liquid against a small pressure in the sprinkler system, the 1/8" tube fittings were not tight enough to hold. I replaced them with 3/16" fittings. The system works with this setup.

Would have given 5 stars if power source worked I didn’t bother to return it because I had another power source so I can’t comment on the return policy but the pump works great

I have had this running at an extremely low 2.1 ml per minute for a few months and it’s been running silently without issue. I like the ability to adjust to a tenth of a ml.

Very happy with that, it works great. You can set the speed. Way cheaper than any other products I saw.

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

Works as it should, very quiet

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.
