SDV Variable Pitch, Screw-Type Dry Vacuum Pump

Screw-type dry vacuum pump with patented variable pitch rotor design commonly used in chemical and pharmaceutical processing.

Models: SDV120, SDV200, SDV320, SDV430, SDV800

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
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.

KDP Screw-Type Dry Vacuum Pump

Model: KDP150, KDP330, KDP400, KDP800

Screw-type dry vacuum pump designed to handle process by-products: liquids, condensate and even small particles.

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.
