Proven technology, proven design –
decide for the best solution
The COBRA NX 0450/0650 A belong to the Busch product family of proven COBRA Screw Vacuum Pumps – Industry. You will find more information on advantages, technology, accessories and spare parts, applications as well as a complete product overview on our COBRA NX series type page.
Series Type Page COBRA NX Two screw rotors inside the cylinder of the COBRA NX rotate in opposite directions. The pumped medium is trapped between the cylinder and screw chambers, compressed, and transported to the gas outlet. During the compression process the screw rotors do not come in contact with each other or the cylinder.
Thus, no lubricants or operating fluids are required in the compression chamber. COBRA NX series vacuum pumps use efficient water cooling resulting in an even temperature distribution throughout the pump body, and guaranteeing thermal stability throughout the process.
