Product Description

DRV020B Double-stage,Oil-lubricated rotary vane vacuum pump,rotary piston pump,rotary vane blower

Pransch air rotary vane pumps have been the most popular pumps for generating low and medium vacuum for many years now. They are sturdy and have a long life, whether they are used as backing pumps to generate the backing pressure called for by turbopumps, or as a single standalone pump. Rotary vane pumps belong to the family of displacement pumps and convey a virtually steady low-pulsation suction volume flow, irrespective of the type of gas used. They work on the principle of an eccentrically supported rotor revolving in a housing, and have two or more movable vanes. Every Pransch rotary vane vacuum pump is oil-lubricated. Special vacuum oils, also known as operating fluids, are responsible for insulating and lubricating components, resulting in very low final pressures. The oil lubrication also ensures an extremely long lifetime, even in continuous operation.

Pransch Air two-stage rotary vane pumps, Their long life and pumping speed, irrespective of the gas used, are the outstanding properties of these pumps. Two-stage rotary vane pumps can be used in the pressure range between 100 hPa and a pressure roughly a decade above the final pressure. they are available in a standard version with a shaft seal for use in straightforward applications. also additionally available as an instrumentation version for more sophisticated applications, such as frequent cyclical pump-down processes (load locks). There are various corrosive versions available for pumping aggressive media. 

Typical applications are found in widely ranging sectors:

• Analytics (mass spectrometry, electron microscopy)
• Coating technology (surface protection, decorative films, display units, monitor screens)
• Medicine/pharmaceutical technology (plasma sterilization, freeze drying)
• Vacuum metallurgy (vacuum soldering, vacuum sintering, vacuum alloys, furnace construction)
• Leak detection technology (vacuum systems, automotive tanks, airbag cartridges, packaging)
• Research institutes (elementary particle physics, fusion research, laser applications)
• Lighting industry (light bulb manufacture)
