After reading about water arc jets and plasma blasts, and the pondermotive forces created by microwaved plasmas, It wouldn't suprize me to find a usefull pump could be made:

1. With a series of high-current capactive discharged along a glass pipe, MHD-caterpillar style;

2. Using a microwave excited spiral antenna around the vacuum plasma tube, to electrodynamicaly pump plasma out.

One other thing to consider is, if you have a self-consistant pressurized plasmiod with a beta (the ratio of magnetic to gas pressure) > 1, then you might start the plasmoid with an energy bang in a relatively high vacuum and just supply enough energy to the plasmoid to keep it hot enough to repel the ambient gas pressure.

The papers on the electron-spiral toroid state that it will repel ions away from it, though probably with power loss.

Of course you need to know the field configuration and parameters of the plasmoid to be able to spawn it.
