I don't know about that - all that proves is that the pump hasn't been opened since inspected. While I suspect even that isn't foolproof, there's nothing stopping someone from modifying the pump through external means, whether through a remote firmware update or mechanical means, like a magnet placed on the outside of the pump that engages some hidden mechanism.
