Large pumps aren't too efficient when the quantities are small. If you have some fluid dribbling in slowly, the small pump may be better (though probably better yet is to use a hydro sensor). Also, one may want to drain something, but can't quite afford to have it running all the time. Though again, using clock automation might be a tad better here.
