Is 'eductor' the same as 'educator'?

No. 'Educator' is a teacher. 'Eductor' is a technical device. They share a Latin root (educere - to lead out) but are different words.

Where would I encounter the word 'eductor'?

In technical manuals for ships, industrial plants, firefighting equipment (foam systems), or chemical engineering processes.

Can 'eductor' be used as a verb?

No, the standard verb form is 'educt' (to draw out), but it is extremely rare. 'Eductor' is almost exclusively a noun.

What is the difference between an eductor and an ejector?

They are often used synonymously in engineering. Some make a distinction: an eductor moves liquids, an ejector moves gases, but this is not universally applied.
