Proven technology, proven design –
decide for the best solution
The COBRA NC 2500 B belongs 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 NC series type page.
Series Type Page COBRA NC Two screw rotors inside the cylinder of the COBRA NC 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 NC series vacuum pumps use efficient water cooling resulting in an even temperature distribution throughout the pump body, and ensuring thermal stability throughout the process.
Air at 20 °C. Tolerance: ± 10%
