The dry screw vacuum pump is a gas pumping apparatus that accomplishes suction and discharge through the synchronous high-speed counter-rotation of a pair of intermeshing screws within the pump casing.The two screws are subject to precise dynamic balancing, supported by bearings, and mounted inside the pump casing.A designated clearance is maintained between the screws, ensuring friction-free operation.The pump operates smoothly with low noise emission, and no working medium is required in the working chamber.

Accordingly, the dry screw vacuum pump is capable of extracting gases laden with substantial condensable vapors and dust particles.It is an eco-friendly and energy-efficient vacuum solution, representing an advanced replacement for oil-sealed mechanical vacuum pumps, liquid ring vacuum pumps, and reciprocating vacuum pumps.

Features:

-- Oil-free pumping chamber ensures no contamination to the vacuum system and improved product quality.

-- Oil-free design eliminates oil emulsification, frequent working fluid replacement and maintenance, reducing operating costs.

-- Dry-running, free of oil and fumes, eco-friendly and petroleum-saving. Capable of handling large amounts of water vapor and dust-laden gases. With optional accessories, it can extract flammable, explosive and radioactive gases.

-- High ultimate vacuum for medium and low vacuum applications. Can be combined with Roots pumps to form oil-free medium vacuum systems, or with molecular pumps for oil-free high vacuum systems.

-- Anti-corrosion coating available, ideal for distillation, drying and degassing processes in pharmaceutical and chemical industries.

Typical Applications:

-- Industrial Furnaces: Vacuum brazing, vacuum sintering, vacuum annealing, vacuum pressure gas quenching, vacuum dehydrogenation, etc.

-- Vacuum Coating: Vacuum evaporation coating, magnetron sputtering coating, roll-to-roll continuous thin-film coating, ion plating, etc.

-- Metallurgy: Special steel smelting, vacuum induction furnace applications, vacuum desulfurization and degassing.

-- Electrical Engineering: Vacuum casting of transformers and mutual inductors with epoxy resin, vacuum oil impregnation of capacitors, vacuum pressure impregnation.

-- Drying: Vacuum pressure swing drying, oil-gas tank drying, wood drying, vegetable freeze drying.

-- Chemical & Pharmaceutical Industries: Product distillation, drying, degassing, material conveying and other processes.
