The SDV Variable Pitch, Screw-Type Dry Vacuum Pump is ideal for use for chemical and pharmaceutical processing, solvent recovery, forming, crystallization, dry etching, sputtering, and vapor recovery. The unit has an innovative pitch rotor design that lowers overall power consumption by as much as 30% as compared to standard fixed pitch designs. The pump prevents process gases from mixing with oil or water, and eliminates metal to metal contact between machine parts. The reliable and sturdy unit can accommodate transfer of process by-products, liquids, condensate, and small fragments. The unit offers quiet operation, pumping speeds up to 1 Torr (1.3 mbar abs), and can handle pressures to 0.02 Torr (2.7 Pa). The C-face motor design eradicates the necessity for motor coupling and guard, and has a short gas path through the pump for swift and easy discharge.
