Kamoer NKP Low Flow Peristaltic Pump 12V DC DIY Liquid Small Dosing Pump for Aquarium Lab Analytical 3mm ID x 5mm OD

I used this pump to remove water from an under-floor burst pipe. I ran it 24/7 from 12V batteries and it never let me down. It did get quite warm at times, but kept on running. Pretty quiet as well.

Bit noisy, but gives consistent results. Have had to replace some tubing and do some basic maintenance every now and then but, for the price not too bad. I would maybe use cautiously if used in a critical environment.

this pump was used for a proto type self watering hydrophonic system, and so far has been very good

The motor shaft drive the rollers via friction. Once it was primed at the first use and stayed off for 12 hours, the pump did not restart, only the motor spun as the friction was not enough to overcome the resistance of the liquid in the tube. Poor design.

I live in the deep South where it's hot and humid. We use the A/C for 10 months of the year. If I forget to put vinegar down the condensate drain every month, it clogs. After dealing with clogs a couple times this year, I decided to use this peristaltic pump to deliver white vinegar into the condensate drain every week. I have it wired to a zigbee relay, and then entire system is controlled by a Hubitat hub. One end of the tubing from the pump sites in the condensate drain, and the other end is in gallon jug of white vinegar. Every Saturday morning, a Hubitat rule turns on the relay for 30 seconds and then shut it off. This delivers about 50 mL of vinegar down the condensate drain. So far, it has stayed clear with no clogs.

I have two of them pumping water to my indoor plants. They are powerful enough to have 4 drip irrigation outlets each.

Muy práctica, la utilicé para un proyecto de posgrado y funcionó a la perfección

I'm using 6 of these pumps (one per pot) in an ESP32 controller based plant watering system I designed and built. I've got a container I'm using as a water reservoir, and use flexible silicone tubing to deliver water, with a tee at each point where I've got a pump connected. I'm driving these pumps with only 5V instead of the 12V spec, and they work fine (at a lower flow rate, of course). I've calibrated the pumps to know their actual flow rates (they vary about +/-15 percent from average). Although there is unit-to-unit variation, they are very repeatable over time once calibrated. I've got soil moisture sensors in each pot, so with the appropriate number of days between waterings, and when the soil reaches the appropriate level of dryness, I command these pumps to deliver a specific amount of water (different for each plant). I've been using them for several months now, and all are still working perfectly.
