waterpump and fan?
How does a bad waterpump cause the radiator fan blades to break off?

2 months ago I got my waterpump replaced. Next thing I know is that my fan blades broke off. Then I got a new fan and fan clutch.
Last week fan broke again... Took it to a BMW speacialist. They said the engine mounts looked fine.
They changed the waterpump, fan, shroud, radiator. Note all oem parts.
The old waterpump (2 months old) the metal impeller does not spin around freely, it seems as it broke. Note it was an aftermarket part.
My question is... can a bad waterpump cause the fan blades to shear off???
Can this bad waterpump be taken back to the parts store, i've got all my receipts... and will they be responsible for the fan...etc?
Thanks for your input.
