COBRA Industry

Dry screw vacuum pumps

cobra_nx_0450_a

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 NF

cobra_nf_0950_a
The dry solution for vacuum packaging

  • Advanced screw design
  • Dry and contact-free operating principle
  • Optimized for vacuum packaging
  • Easy cleaning with steam jets and conventional detergents
  • Efficient water cooling
  • Quiet
  • Compact design

Benefits of the series

COBRA NF dry screw vacuum pumps have been specially designed for vacuum packaging. They offer fast pump-down of the packaging chamber and maximum productivity.

The patented self balancing screw design ensures lowest vibration levels and quiet operation.

The screws of COBRA NF 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.

You can easily clean COBRA NF series vacuum pumps using steam jets and conventional detergents. Because of the smooth surface design water and detergents drain away leaving a residue-free finish.

Thanks to an efficient water cooling, only ten percent of the generated heat are released into the environment.

The COBRA NC 0500 B also belongs to this series, which has been specially designed for food applications.

Benefits of the COBRA NC series

COBRA NC are high-performance dry screw vacuum pumps. They are perfectly suited for demanding applications with maximum flexibility and modularity for process changes. COBRA NC 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 NC 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 NC series vacuum pumps use efficient indirect water cooling. This results in an even temperature distribution throughout the pump body. Moreover, thermal stability is ensured throughout the process.

The COBRA NC series comprises a range of application-specific versions. ATEX-certified versions for use in explosion-hazard environments are also available.

COBRA NS

cobra_ns_0600_c_1
Leak-tight vacuum generation for demanding processes

  • Advanced screw design
  • Dry and contact-free operating principle
  • High vapor and particle tolerance, self-draining
  • Leak-tightness
  • Extended service intervals
  • Efficient indirect water cooling
  • Quiet

Benefits of the COBRA NS series

COBRA NS is a series of high-performance dry screw vacuum pumps for demanding applications. They are in use wherever gases and vapors need to be pumped reliably, such as coating applications, helium pumping or fluorination.

The integrated motor makes this vacuum pump series leak-tight with a leakage rate of < 5.0 · 10-5 mbar · l/s.

The bearings of COBRA NS vacuum pumps are lubricated with Busch PFPE oil. Therefore, service intervals are extended to a maximum.

The screws of COBRA NS 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. Optimum corrosion resistance is furthermore ensured thanks to temperature control and special coatings on the screws.

COBRA NS series vacuum pumps use efficient indirect water cooling. An even temperature distribution throughout the pump body is therefore maintained. Moreover, thermal stability during the process is ensured.
