I am currently building a pour over coffee maker(personal use), but I am having trouble sourcing a water pump to use. I am hoping to create something that performs similar to the Poursteady commercial machine. My current plan is to boil the water to a specific temperature in a kettle, then use a water pump to pump the water from the kettle into the coffee funnel containing the grounds. I'm doing all the automation using an arduino.
Requirements for the pump:
- Food grade
- Safe to pump ~100c water
- A flow rate of >=500ml/minute
- Either AC or DC is fine
- The more affordable the better. Self priming
I believe peristaltic pumps, magnetic pumps, and vibration pumps all seem to be okay options, but having zero experience with pumps, I am wondering if any of them are recommended over the other given the specific requirements.
