dosing pump questions

[MDB1029]

I am thinking of buying a couple of the RA dosing pumps but can't find any information about them. I am trying to find out how they hook up, how the code would need to be written, if there are any other modules i would need to run them, what the minimum and maximum flow is? Are there any reviews, or pros and cons of these pumps. If anyone can point me in the right direction it would be greatly appreciated.

They use outlets on your relay box. They can also use the power relay box. Essentially they use 12v ac/dc transformers
