It's done all the time with centrifugal pumps. They just need to be sized properly. And you won't overcarbonate your beer, like you can do with overpressurized tanks. Do you have any candidate pumps lying around? What's your max and min flow rate? What's your temperature? Is it a 1 1/2"TC beer line? What maximum filter pressure drop will you see? And what volume do you package in a day & given week?
