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.

Abstract: A rotor assembly for a multi-stage pump is provided. The assembly comprises a drive shaft, a rotor component and a drive component. The rotor component is located on the drive shaft and comprises a rotor element for displacing fluid through the pump when the drive shaft is rotated. The drive component is anchored to the drive shaft and transmits torque from the drive shaft to the rotor component to effect rotation of the rotor component. A sleeve element is integrated with either the drive component or the rotor component and is used to space the rotor element from the drive component. An interface surface is located on the sleeve element for interacting with the other one of the drive component and the rotor component in order to maintain orthogonal alignment between the rotor element and the drive shaft. Drive means is provided for transmitting torque between the drive component and the rotor component.
