Patented variable pitch rotor design reduces power consumption by up to 30% as compared to fixed pitch designs
No oil or water in contact with process gases
No metal-to-metal contact between operating parts
Simple, robust design can handle process by-products – liquids, condensate, and even small particles
Flows: 60 – 1600 CFM (100 – 2700 m³/h)
Full pumping speed to 1 Torr (1.3 mbar abs); ultimate pressures to 0.02 Torr (2.7 Pa)
Space saving C-face motor design eliminates need for motor coupling and guard (models SDV-120 – 800)
Short gas path through the pump for quick discharge
Quiet operation – less than 90 dB(A)
