What you have there is a parts pump. You can do one of three things with it.
You can part it out and try to make enough from the parts sales to help with your purchase of a complete pump----
OR
You can try to gather enough parts, reasonably, that you can put it all together and not have more into it than a complete one would have cost in the first place----
OR
you can set it in a prominent place where you will see it every day and admire your first pump purchase----
All of these options are dependent on your initial purchase price and that should guide you to the direction you need to go. Most parts pumps are better off sold for the parts and the funds reinvested. There isn't an excess of parts available for these pumps, so most of it should sell well, but again, it makes a difference what your initial investment was? Good luck!
