Technical Specifications
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.
Accessories and spare Parts
Sealing gas supply for seals used with applications particularly subject to damp or dust
Gas-ballast valve to increase water vapour tolerance
Exhaust gas silencer to reduce noise
Radiator cooling system
