Gikfun 12V DC DIY Peristaltic Dosing Pump Head Replacement for Aquarium Chemical Lab Analytical Water EK1990

The pump is decent quality. It’s exactly what I would expect from a product at this price.It comes in a clear box that kept it clean and free of damage.I don’t have any kind of standard pump unit, so I can’t comment on how it will fit for you. I have this attached to a stepper motor with a custom controller.

Unfortunately, this does not fit my particular device, there is no central arbor for driving the rollers. However this is because this pumphead is for a different device than mine.

These 12V DC DIY Peristaltic Dosing Pumps are good for DIY projects where you need to measure an exact amount of liquid. You can use them with Arduino/ESP32/Raspberry Pi to output a specific amount of liquid when needed. For example you could have a hydro culture system where an ESP 32 took nutrient level readings then added fertilizer as needed. There are so many things you can do with these where you need specific amounts of liquid dispersed.

I use a small low-flow peristaltic pump for sample preparation in my lab. These spare parts are useful! Better to keep using the pump instead of spending on a new one and saves money. Exactly as described, I’d recommend.

Several years ago I made a 4 chem laundry dispenser, a month ago one of the pump heads had something spilled on it that really messed it up... This little parts kit contained all the parts to replace the whole thing. It was identical to the pumps in every way. Simple, flawless replacement that only took a few minutes to do. I could not be more grateful that I did not have to buy the whole thing!
