The NASH VWN Roots booster pump is a device with a wide vacuum range, high pumping speed, and low cost. It can be combined with various vacuum pumps to form a composite vacuum unit. All products undergo dynamic balancing and leakage testing before leaving the factory. The VWN Roots booster pump composite system has been widely used in industrial fields worldwide, such as chemical, petrochemical, plastic, semiconductor, wood mixture, food processing, vacuum furnace, chemical and pharmaceutical engineering, power, vacuum melting and space simulation, and other application areas.
Product advantages of VWN Roots booster pump composite system:
►Five bearings, including one on the outermost side of the shaft, ensure the durability of the VWN Roots vacuum pump.
►Synchronous helical gears are easier to ensure synchronization, ensuring quiet and reliable operation. The installation of this synchronous helical gear at the drive end reduces the torque load on the rotor.
►Five point mechanical seal, a typical sealing structure is a dual seal of PTFE labyrinth seal and mechanical seal, which can achieve no leakage and reduce maintenance and repair steps.
►There are various materials available for the O-ring of mechanical seals, such as Kalrez ®， Viton ®， PTFE coating, etc.
►Two blade Roots rotor: impeller and shaft cast together: can provide large-sized shafts and reduce the risk of impeller damage.
►All end faces of the shaft in contact with the seal are polished to reduce seal wear and reduce the risk of leakage.
►The impeller is directly connected to the cavity, reducing the risk of the impeller losing balance when liquid is drawn in.
►Specially sturdy shell, suitable for reliable operation under high temperature and high pressure.
►Both ends have oil tanks to ensure better lubrication and reliability.
