I am looking for an economical 12volt hydraulic pump to power my landing gear. I currently have an old hand pump that has seen its share of use and is not functioning well. I would be interested if someone knows a good source for a electric pump or a new hand pump.

Look at the marine industry.  The pump used by many kitplane manufacturers is the same as is used by Mercruiser to raise and lower the out drive.

There is a small but powerful 12 volt pump that was used in the old Chevy Citation convertible. If you go on ebay you will find some. They have a small reservoir, but they work well. I used one on my test stand for my prototype landing gear. There is video on my website.

Looks like a Coot.  The one I built had a screw drive, but not according to plans.  You may consider using one from a marine drive. as one suggested.  Piper uses them (and has for a long time) in their retracts, such as the Arroes  They are small, light, and powerful.
