The Screw Pump is one of the simplest positive displacement pumps, and has been used for thousands of years to move water, mainly for irrigation purposes.
A screw pump can have a few different configurations, including a tube wrapped around a shaft, or a tube enclosing a shaft with a screw wrapped around it.
Probably the easiest way to manufacture a screw pump would be to opt to use the tube wrapping configuration, perhaps molding a clay or porcelain tube around a central shaft, and then firing it in a kiln. It's conceivable that this fashion of screw pump could also be assembled from a joining of segmented parts, perhaps constructed out of wood, which would make adding or subtracting length easier, as long as some method of watertight joinery could be used. The method of the enclosed screw is dependent on tight manufacturing tolerances that would be difficult to achieve without machining tools.
