Screw vacuum pump DRY-PRO VSB

oil-freesingle-stagefor the chemical industry

Nash's VSB Series of dry screw vacuum pumps offers a wide operating range, backed by reliable performance and low lifecycle costs. Dry screw pumps can handle corrosives, organics, inorganics, and solvents because of its oil-free, non-contacting screw design making it an ideal choice for chemical, plastics, industrial, petrochemical, and packaging industries. Dry Screw Vacuum Solutions | VSB Series Dry screw vacuum pumps are an increasingly popular choice across industrial applications and, in certain conditions, serve as an excellent alternative to liquid ring vacuum pumps. The VSB Series of dry screw pumps were designed with a robust casing and rotor that operates with low noise levels and is simple to service and maintain. Our dry screw vacuum pumps & systems deliver a clean, oil-free vacuum for a variety of industrial applications. In these applications, our pumps perform with low rotational speed which ensures a smooth and robust operation. Higher discharge pressure capabilities along with a high tolerance for vapor and dust guarantee more process time with long service life. The VSB Series offers a remarkably simple, yet sophisticated design, that offers safe and reliable performance with our non-contacting screw design. Dry Screw Pump Working Principle A dry screw vacuum pump consists of two parallel, non-contacting helical screw-shaped rotors rotating synchronously at high speeds via precision gears. They rotate in opposite directions, and in so doing, trap a quantity of gas at the inlet and transport it towards the exhaust port and into the exhaust channel.
