Medical vacuum pump COBRA NS 0070 C

screwoil-freelubricated

High vapor and particle tolerance, self-draining Leak-tightness Extended service intervals Efficient indirect water cooling Quiet Benefits 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. Advanced screw design, patented self-balancing screws, perfectly suited for coating applications, helium pumping or fluorination Efficient Low cost of ownership, minimal maintenance, long service intervals, high uptime, efficient water cooling Leak-tight design Integrated motor, no contamination of process gases, gas-tight
