Controlling 4 simple pumps with variable flow rates

Hello,

I need to control 4 pumps, each with variable flow rates. Preferably I would use 4 cheap pumps like this: https://www.adafruit.com/product/1150?gclid=CjwKEAiA94nCBRDxismumrL83icSJAAeeETQoOZS5HvoHg-rRHnDauHFNPwpLSqHu7GSQxgk6-IXYxoCAvvw_wcB

What other equipment would I maybe need?

Any help would be much appreciated
