  • Applications:

    for the chemical industry, for pharmaceutical applications

  • Flow rate:

    Min.: 100 m³/h (3531.47 ft³/h)

    Max.: 750 m³/h (26486 ft³/h)

  • Ultimate vacuum:




• Patented variable pitch rotor design increases efficiency and lowers temperatures
• No oil or water in contact with process gases
• Can handle both condensible vapors and some solids without leaving residue
• Capable of full pumping speed from atmospheric pressure to 1 Torr (1.3 mbar a)
• Can achieve ultimate vacuum as low as 0.01 Torr (0.013 mbar a)
• No metal-to-metal contact between operating parts
• Quiet operation
• Niflon coated internals reduce damage from corrosive or condensable gases

The SDV’s space saving C-face motor design eliminates the need for motor coupling and guard. It features a short gas path through the pump for quick discharge.
