What kinda pump can use this large impeller?

it is certainly a below density around 1000kg/m3 .
water turbine impeller
most likely

Probably but I just wonder what capacity it operates, like what volume of water does it pump in an hour? Possibly used in hydroelectric power generation

It appears like they use milling machine to cut it Shaft hole key way.




The volume will be tied to the speed and the surface area of one of the impellers.
The speed won't be too great to disallow wear.
Surface are should be around 0.4m2. For each impeller.

Nice update, seems you have worked around such equipment before

Yes I work around such.
