Abstract: A dry pump (10) has adjacent its inlet (12) and between the inlet and pump foreline (14) an apparatus for abating the back flow of organic molecules originating from a lubricant used to lubricate a drive mechanism of the pump. In one embodiment, the apparatus comprises a first compartment (18) having extending from its internal wall a plurality of cooling baffle plates (20). The cooling baffle plates are cooled by means of a water-cooling coil (22). Between the first compartment (18) and the foreline (14) is a second compartment 24 having extending from its internal wall a plurality of interleaved baffles (26). These baffles are coated on their surfaces with activated charcoal pellets for adsorbing halocarbon molecules back-streaming from the pump inlet.
