Principle of DP vacuum pumps The COBRA NS screw vacuum pumps work by the principle of spiral pumps. Two parallel screws (8) rotate in opposite directions in the pump body. Entering gases are trapped between the flights of the screws and the pump body. The gases are conveyed by the rotation of the screws to the exhaust, where they are discharged. Principle of MB vacuum pumps The WY Roots vacuum pumps operate according to the approved principle of the Roots type machine. Operation is both simple and effective. Two lobe rotors (1) with identical profiles rotate in opposition directions within...

Safety information on the NS 0070 C pump Intended use DEFINITION: To rule out any misunderstanding, the term “handling” of the vacuum pump covers transport, storage, installation and operation of the pump as well as effects on operating states and troubleshooting on the vacuum pump. WARNING Hot surface Do not touch The vacuum pump is intended for industrial use. It may only be operated by qualified personnel. The different application possibilities and limit values for operation described in “Product description” and “Installation requirements” must be observed by the manufacturer of the...

Transport in unpacked state The vacuum pump is fastened to the pallet with fixing pins: u Unscrew the fastening nuts underneath the pallet. CAUTION Do not work, walk or stand under suspended loads. NOTE: VCI is the abbreviation for “volatile corrosion inhibitor”. The VCI molecule is an organic corrosion inhibitor in the vapour phase. Integrated in various carriers such as film, cardboard, paper, foam, liquid and powder, it protects the parts against corrosion as a result of its action in the vapour phase. However, VCI packaging can attack synthetic surfaces and surfaces of other elastomers....

— Approximate flow rate: 6 - 7 l/ min for the standard version (hot pump) — Approximate flow rate: 6 - 15 l/ min for other applications • Make sure that the cooling water is neutral and clean • Make sure that the cooling water outlet is unpressurised CAUTION When the intake lines have been connected, make sure that the system does not leak. Leakages of dangerous substances must be prevented! • Make sure that the nitrogen fulfills the following requirements: — Overpressure: 1,5 bar — Approximate flow rate: 0 - 75 l/ min • Make sure that the ambient conditions correspond to the protection...

Cooling water connection The cooling water is generally connected with a hose. The cooling water outlet must be unpressurised. Connection diameter: 3/8 NPT Nitrogen connection The nitrogen is connected with a pipe (leakproof against oxygen). Connection diameter: 1/4 NPT Electrical connection/ Checks • Make sure that the regulations of the Electromagnetic Compatibility Directive 2014/30/EU as well as standard EN norms, safety directives and especially local and national regulations are observed (this is the responsibility of the manufacturer of the system into which the vacuum pump is...
