Yes, in the thought experiment it runs underwater. It's fine though because it can run underwater in both cases, so that doesn't ruin the symmetry.
The article implies a situation where the pump is running in the opposite direction as normal, sucking the water in. That's not time-reversed though (eg in the time reversed version, the pump generates electricity instead of consuming it, because the water is pushing it instead of it pushing the water)
