Abstract (en)

[origin: WO2017081179A1] The invention relates to a delivery device for a vacuum distillation plant for substance mixtures that polymerize and/or decompose easily, in particular acrolein, in which plant an intermediate product formed in a preliminary stage is delivered by means of a pump into a vacuum distillation column (37). The invention is characterized in that the pump is a hermetically sealed centrifugal pump (31) with a magnetic coupling, and in that a pressure-maintaining control valve (34), which is configured to adjust the throughput of the centrifugal pump (31) to a predetermined value, is provided between the centrifugal pump (31) and the vacuum distillation column (37).
