About the series

Technology and features

Operating principle

Scroll vacuum pumps compress the gas between two intermeshing spirals: one spiral is fixed, the other orbits, so that the gas is conveyed from the outside inwards to the outlet in chambers that become ever smaller. The pump chamber is oil-free, and the pumps run quietly and with low vibration.

The technology page shows the operating principle with an interactive drawing: Scroll vacuum pumps.

Features of the series

  • Leak-tight: leak rate 1 × 10⁻⁶ mbar·l/s
  • Three versions: standard with gas ballast, H without gas ballast, C for aggressive applications
  • Single-phase or three-phase: 100–127 V / 200–240 V or 200 / 380–415 V (50 Hz) and 200–230 / 460 V (60 Hz)
  • Quiet: less than 55 dB(A), low vibration (below 4.5 mm/s)
  • Certified: ATEX II 3 G Ex h IIC T4 Gc X (internal atmosphere only)
  • Oil-free: dry scroll principle, no oil in the pump chamber
