Need Stronger Peristolic Pump

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.

Any recommendations?

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!

Hey @simon_waffleman

The RobotShop’s catalog has some pumps, but I’ve selected the two that COULD fit your needs:
This pump has a flow rate of 0.5-1L/min with no load: https://www.robotshop.com/en/6v-micro-water-pump.html
This pump has a flow rate of 1.5-2L/min : https://www.robotshop.com/en/6-12v-r385-dc-diaphragm-pump.html

You can find the pump and tubing selection here: https://www.robotshop.com/en/pumps.html
