Dry Screw – KDP
Features
• Simple, robust design can handle process by-products
– liquids, condensate, and even small particles
• No oil or water in contact with process
• No contact between operating components in the casing
• Full pumping speed from atmospheric pressure down to
1 Torr; ultimate pressure 0.1 Torr
(.05 Torr on Model KDP-800)
• Quiet operation – less than 85 dB(A)
• Short gas path through the pump for quick discharge
• Extended shaft for either V-belt or direct drive
Casing and rotors are made of ductile iron, PFA coated.
Typical Applications
• Solvent Recovery
• Vapor Recovery
• Vacuum Packaging
• Freeze Drying
Models: KDP150, KDP330, KDP400, KDP800
Dry Screw – SDV
Features
• 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
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.
Typical Applications
• Chemical & Pharmaceutical Processing
• Solvent Recovery , Crystallization ,Vapor Recovery
Models: SDV 120, SDV 200, SDV 320, SDV 430, SDV 800
