I have a bunch of these handy:
However, they’re not strong/fast enough! I want something 2x or 3x the output.
I’m looking for something that will move fluid faster and that is food-grade for a home project. I’m hooking it up to an 8-channel realy (https://www.amazon.com/gp/product/B00KTELP3I). I’d love to stick with the tubing I have ( Non-DEHP Laboratory, Food & Beverage and Vacuum Plastic Tubing, Clear, 4mm ID x 6mm OD) but I’m not opposed to buying something thicker.
I’m not extremely worried about major accuracy so it’s not much of an issue.
BTW - I absolutely love these forums and I love RobotShop.com. I’ve used tons of posts and haven’t had to open an account until now for this specific question because so many things have already been answered!
