I sincerely doubt that pump is "food grade"; for one thing, it doesn't cost enough...
Now - will it cause you harm to drink liquids pumped by it? Doubtful. However, you may be limited in what liquids you can pump - plain water is probably OK, but anything with a high alcohol concentration, or anything else which can affect the operation of the pump (seal deterioration, or leaching of the likely non-food grade lubricant) might pose problems.
Of course - this would all only be for "personal use". If you try to install whatever it is you are building into a commercial operation (kitchen, food service, etc) and the health inspector sees it, you won't pass (assuming that's all they do, of course)...
