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.
