COBRA NX 0650 A

Busch COBRA NX 0650 A – dry screw vacuum pump

The Busch COBRA NX 0650 A is a dry screw vacuum pump. The nominal pumping speed is 650 m³/h, the ultimate pressure 0.1 mbar. Nominal motor rating 12.5 kW (50 Hz) or 15 kW (60 Hz).

Features

• Powerful: screw design with patented self-balancing screws, for heat treatment, coating, vacuum packaging, vacuum drying and degassing
• Efficient: low operating costs, little maintenance, long maintenance intervals, high availability, water cooling
• Flexible: modular design, easy to combine with PANDA vacuum boosters for a lower ultimate pressure and higher pumping speed

Typical applications

Busch lists: Automotive and transport (leak detection and EoL testing, heat treatment, electron beam welding); Batteries (degassing, mixing, impregnation and others); Biogas handling (upgrading by pressure swing adsorption); Carbon capture (direct air capture); Chemistry (freeze drying, lyophilisation); Confectionery (mixing, preparation and cooking); Food processing (meat tumblers and marinators, vacuum cooling, freeze drying and others); Hydrogen economy (leak detection and EoL testing (master)); Metallurgy (heat treatment, vacuum brazing, vacuum sintering and others); Packaging (liquid packaging, chamber machines, large, industrial, rotary table/carousel packaging machines and others); Pharmaceuticals and biotechnology (freeze drying, lyophilisation); Plastics processing (drying, degassing, dissolution); Power generation (green power generation, transformer drying, transformer oil purification); R&D (freeze drying, lyophilisation); Refrigeration and air conditioning (leak detection and EoL testing); Solar (cell production, laminating); Industrial gases (liquefaction, gas transport, insulation vacuum).

Accessories and versions

• Barrier gas connection for seals in applications with a high vapour or dust content
• Gas ballast valve for increased water vapour tolerance
• Exhaust silencer for quieter operation
