What kind of equipment is this? Why does the drive shaft look like a universal joint? ? ?

It must be a pump, but the pump casing is square, and the bones are surprising, so it should not be an ordinary pump. Why is it not directly connected? It should be because the axial change is relatively large, so why not use a belt? It should be due to temperature reasons.
The analysis makes sense, as if you know something
High temperature gear pumps are used to transport high temperature viscous media.
I’ve never seen it before, and this is the first time I’ve seen such a strange-looking pump.
In order to solve the problem of high temperature expansion, the middle universal joint shaft is a solid shaft inserted into the hollow shaft, which can be freely expanded and contracted to compensate for the axial expansion.
