High-Speed Direct-Coupled Lab Mechanical Vacuum Pump – 5×10⁻² Pa Ultimate Pressure

The lab mechanical vacuum pump is a high-speed direct-drive (motor-driven) two-stage rotary vane oil-sealed variable-volume vacuum pump. The pump body features an integrated design with a built-in gear oil pump, a pressure oil control anti-backflow valve, an oil pump pressure control system, low-noise NSK bearings, and a well-designed lubrication and sealing structure.
