Vacuum Gear Pump

Complete systems for rotary evaporation, vacuum, and filtration manifolds
  • Dual-stage gear pumps provide deep vacuum to 1 x 10–1 torr
  • Rotating gears do not mesh — very tolerant of vapor and provide smooth, low-maintenance operation
  • Use for distillation and removing high boiling point solvents
  • Exhaust oil recycler coalesces oil mist and puts it back into the pump to prevent build up of oil residue in filter
  • Gear design allows pump to operate continuously between 0.1 torr and at atmosphere, unlike a rotary vane pump
