Wood Screw Pumps
Wood Screw Pumps
(OP)
are actually axial flow turbine pumps, but there wasn't a precise taxonomy when they were built.

I'm just as impressed with the motor, through which we are viewing Mr. Sullivan in the photo.
The flows quoted are not misprints. The white object in the background is the pump housing, which in the case of this smaller pump, is 12 feet in diameter.

If we learn from our mistakes I'm getting a great education!

End view of pump section during construction:

There's an axial cross section near the bottom of this:

I.e., the pump is a gigantic single stage axial flow turbine, in an inverted u-tube. In the Times-Picayune photo referenced above, you're looking through the motor rotor, along the (long) shaft, and seeing the rising inlet half of the u-tube. The turbine blades are within it, near the plane of the far wall of a fair sized building.
Multiple arrays of these pumps keep New Orleans from flooding every time it rains.
I first learned of them right after Katrina.
Now I'm working in the area, so they have taken on a new importance.
