I've always had good luck with companies replacing defects and returning the the broken. Just need to sweet talk a little bit. I found they will take you broken pump under the warrenty and then supply you with a replacement off the shelf. They deal directly with their distributor and you never seen that pump/equipment again.
If I were you, I would chase your pump over in germany and raise a stink. And raise a stink here with whoever sent it to germany, someone put it on a plane. People tend not to like disgruntled people making stinks
