Kamoer M1-STP Intelligent peristaltic pump 24V stepper motor adjustable programmable low flow liquid dosing pump with control for laboratory aquarium 0-88ml/min

Outstanding product. Equivalent pumps are hundreds of dollars more. This has every feature I could want and does the job very well. Relatively few reviews at the time but very glad I took a chance.

Llego puntual y el producto es de calidad.

This little peristaltic dosing pump works great. I am a water operator and using this pump to dose a mixture of diluted chlorine and water of 25,000ppm into a 1000 gallon potable water tank only when the well pump runs. It will keep the water at a constant 1 to 2ppm to eliminate bacteria forming in the water system. It has multiple programable settings for whatever you need it to do. Has a color display that is very nice to see and use settings to control the pump. Although it doesn't show it in the pictures, it comes with its own 24v/ 48 watt power supply that can operate on the 240volts power from the well pump pressure switch. The pump is made of high quality materials and also looks to be of high quality when manufactured. It has a variable speed knob that can set the rpm from .01 to 350.0 rpm per minute which doses from 0.1 to 88ml. Also has a small internal fan on the bottom to cool itself. It is quiet but you can here the fan a little which is fine. I am very impressed with this chemical dosing pump especially at this price.

I'm using this to add bleach to chlorinate flowing well water. Once calibrated and you figure out how much you need to add based on iron and bacteria content of your water, just set and forget. I have it power on when the well pump turns on. It is very configurable.
