C Series

VPS-C Series Dry Vacuum Pump

Characteristics of

Applid variable pitch screw
  • Prevention of coating damage by pump temperature rise
  • 30% reduction in power consumption by energy-saving design
Vacuum degree improvement
  • Reaches the maximum vacuum degree 0.0075torr(1Pa)
  • Increase pumping volume from high vacuum
  • Maintaining stable volume from atmospheric pressure up to 1torr(133Pa)
Spiral coolant jacket
  • Excellent cooling efficiency of the spiral jacket
  • Low operating temperature
  • Controlling temperature inside the pump with a small amount of coolant
Smooth discharge structure
  • Short gas path through the pump makes quick gas discharge
  • Smooth condensate draining within the pump
  • Excellent liquid handling ability
IEC Flange (NEMA Optional)
  • Mostly C-flange design simplifies mounting reduce noise level and eliminate shaft alignment
  • Rib enhancement for deformation and vibration prevention
