ID: 185418
Turbo molecular pump.
PFEIFFER / BALZERS TMH 520SG is a centrifugal, oil-sealed mechanical pump designed for industrial vacuum applications. It offers suction speeds up to 902 m3/hr and ultimate pressure of 5 x 10-2 mbar. BALZERS TMH 520SG pump is a single-stage, direct-drive pump fitted with an 8-pole, robust brushless permanent magnet motor, providing improved performance compared to other sealing products. Constructed from high-grade stainless steel, the pump is equipped with a specialty rotor, that is dynamically balanced to ensure accurate and smooth operation. PFEIFFER TMH 520SG is fitted with a radial oil-sealing system whereby a static, wear-resistant seal is placed between the bearing and the shaft of the motor. This ensures the passage of the pump on the outside is completely sealed and prevents impurities such as dirt and oil mist to enter the drive shaft, thus protecting the pump from possible wear. The radial oil seal is also adjustable meaning the user can adjust the vacuum pump's performance according to the required Vacuum level. TMH 520SG is equipped with a single-stage air-cooling system. A single-stage cooling device is suitable for when the vapor loading is low or moderate. This system maintains optimum performance by providing improved cooling and heat dissipation, allowing the pump to maintain the required vacuum level. Furthermore, PFEIFFER / BALZERS TMH 520SG is designed with a top and bottom mechanical seals, that are carefully designed and can be easily removed for maintenance purposes or for replacing parts. The top seal, in particular, is subject to less heat which helps reduce the seal's performance. Additionally, it is equipped with an Integrated Adjustable Pressure and Suction Control, that provides the user with the option to adjust the suction pressure to their desired level. BALZERS TMH 520SG is efficient and reliable and is suitable for various industrial vacuum applications, such as degassing, evaporators, and dryers. When operated correctly and with proper maintenance, this pump is capable of providing optimum performance and providing years of reliable service.
