COBRA Industry
Dry screw vacuum pumps

COBRA Industry dry screw vacuum pumps are ideally suited for industrial applications which require reliable and contaminant-free extraction of gases and vapors.
The operating principle of COBRA Industry is based on our state-of-the-art screw technology. With their patented self-balancing screws, they set new standards in terms of efficiency.
COBRA vacuum pumps operate efficiently throughout their vacuum range and deliver constantly high pumping speeds.
COBRA Industry vacuum pumps are oil- and contact-free.
Particle-laden media can be evacuated without any problems. Furthermore, maintenance is reduced to a minimum.
Optimum corrosion resistance is ensured by an even temperature distribution preventing condensation.
Operating principle
Inside COBRA Industry dry screw vacuum pumps, two screw rotors rotate in opposite directions. The pumped medium is trapped between the cylinder and the screw chambers. There, it is compressed, and transported to the outlet. During this process, the screw rotors do not come in contact with each other or the cylinder.COBRA NX

- Advanced screw design
- Dry and contact-free operating principle
- High vapor and particle tolerance, self-draining
- Efficient water cooling
- Optional air cooling
- Anti-corrosion coating
Benefits of the COBRA NX series
COBRA NX are high-performance dry screw vacuum pumps for rough and medium vacuum applications. They are in use wherever gases and vapors need to be pumped reliably.
The patented self balancing screw design ensures lowest vibration levels and quiet operation.
The screws of COBRA NX vacuum pumps are manufactured from a single-piece casting avoiding any gaps. This makes an ingress of process fluids or particles impossible. Thus, corrosion and deposition are prevented.
COBRA NX series vacuum pumps use efficient water cooling. An even temperature distribution throughout the pump body is therefore maintained. Moreover, thermal stability during the process is ensured.
