Any pump rated for at least 25ft of head pressure should do.
Personally, I'd look for a large pump of lower quality to keep your price down, since the application is not critical to your tank. Upsizing the line might be something you need to look at. Any pump rated for significant head pressure is going to be a higher flow model, and as such will have larger output connections... 3/4" or 1" probably.
Be sure to go significantly over when sizing the pump. If your height is 16', you'll want to go 25' at least. The head rating of a pump is frequently overstated, and the maximum height is usually when the pump literally completely stops lifting, so if you have 16' of height and you get a pump rated for that, you'll be getting a tiny trickle of water at that point.
