Those hand pumps will only go down to about 0.5 inches of Hg.  I don't 
think this is low enough for any plasma globe experiments.  

It might be low enough for those spark gap nitrogen lasers though!

However, it would be low enough to pump down some capacitors if you are 
willing to operate the pump for a long enough time.

I'd say getting a used 'fridge compressor would be a better arrangement, 
rather than spending $40 for a hand pump.
