I'm not hugely mechanical but I agree with Jim. I would disassemble the pump (there are in instructions on that bearing replacement DIY) and inspect the internal components and if no scoring you could try to sell it. But I guess the market doesn't seem too good for used pumps.
Side note to Jim. I still can't PM but emailed you regarding rod bearing replacement but got no reply. Might want to check your spam folder. Thanks.
