SDV Series

Applications: Chemical & Pharmaceutical Processing, Solvent Recovery, Crystallization, Vapor Coating

SDV variable pitch, screw-type dry vacuum pumps are environmentally friendly as there is less oil to dispose of and maintain within their design. These pumps are more efficient than a liquid-sealed model and are well suited for industrial and process applications. 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.

• 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
• PEEK coated internals reduce damage from corrosive or condensable gases
