These R-series vacuum pumps are dry-running compressors. This means that there is no need for oil or grease in the compression chamber. Only the gear box and bearings, which are separated from the pumping chamber, are lubricated. In the body of the pump, the triple rotors rotate against each other. The triple lobe rotors create a smooth flow. The pumps are factory-customised to cater for a wide range of applications.
