Abstract: An oil-lubricated rotary vane vacuum pump includes a rotary vane unit, having a rotary vane chamber and a rotary vane rotor, and an oil separator device having an air/oil separating unit that has a filter element with a plug-in ring that can be plug-connected on a housing side. The plug-in ring is designed for radial sealing and axial displaceability in a housing receptacle. The filter element has a moulding for bayonet mounting, which faces the end associated with the outer wall. A mounting wall of the housing, extending at a distance from the outer wall of the housing, is designed to interact with the moulding of the filter element and to form the bayonet mounting. A separate cover closes a mounting opening associated with the filter element in the outer wall of the housing. The cover form-fittingly interacts with the filter element to secure the filter element against rotation.

Abstract: An oil-lubricated slide vane rotary vacuum pump with a slide vane unit, and with an oil separating and reconditioning device, wherein oil and gas are separated by separating devices, possibly complemented by oil coolers and/or oil pumps. One or more monitoring and/or servicing devices are provided, and the oil separating and reconditioning device is installed in an oil separating and reconditioning housing. Side walls extend transversely to a plane of rotation of a slide vane rotor, and define a longitudinal extent of the oil separating and reconditioning housing. The one or more monitoring and/or servicing devices are arranged only in one or more cover parts which are attached to one or both end walls of the oil separating and reconditioning housing. The oil separating and reconditioning housing is formed with the side walls, the bottom wall and the top wall without being configured for a monitoring and/or servicing device.

Abstract: An oil-lubricated rotary vane vacuum pump has a rotary vane unit that includes a rotary vane chamber and a rotary vane rotor. The vacuum pump has an oil separation and reprocessing device in which oil and gas that have penetrated into the rotary vane unit are separated by a separation device formed by a filter element and/or a gravitational and/or impact separator and/or a fine particle separator, preferably along with an oil foam decomposition device and/or with an oil cooler and/or with an oil pump. One or more monitoring and/or maintenance devices are provided for the devices, and the oil separation and reprocessing device is accommodated in an oil separation and reprocessing housing. The gas successively flows through two separation devices within the oil separation and reprocessing housing, and the two separation devices are both accessible for maintenance from a face wall.
