    High-Speed Rotor Balancing Stand for Vacuum Pumps Introduction Balancing of high-speed rotors in vacuum pumps requires specialized equipment capable of maintaining accuracy under extreme operational conditions. To meet these requirements, dedicated balancing stands were developed in 2002 and 2009.
