An improved distillation device (1) which uses a combination of centrifugal and positive displacement pumps to purify raw liquid in an area of limited space. The device (1) includes evaporation apparatus (2) having a boiling chamber (5), means (15,16,17) for maintaining the liquid level (20) in the boiling chamber (5) at a predetermined level, and connecting conduit (21) for directing vapor to a condensation apparatus (3). The condensation apparatus (3) includes a condensation chamber (6), a collection chamber (7), and at least one bubble tube (22) connecting the two chambers (6,7). Leading from the collection chamber (7) is first transfer means (50), a tube (51) for permitting vapor to bleed from the collection chamber (7) back to condensation chamber (6), and second transfer means (52) for returning only distillate from collection chamber (7) to condensation chamber (6) to cool condensation chamber (6).
