Description

Overview
  • Three-stage, 4-head diaphragm vacuum pump engineered for conveying and compressing neutral and aggressive gases and vapours in laboratory and light‑industrial chemical applications.
  • All wetted parts PTFE-coated and elastomer/PTFE diaphragms for enhanced chemical compatibility and long service intervals.
  • Continuous oil-free operation ensures contamination-free pumped gases and clean vacuum processes.
  • Compact, low-noise design with carbon-fiber reinforced pump and connection heads to reduce electrostatic charging and ignition risk for flammable mixtures.


Key features
  • Chemical resistance: PTFE-coated wetted parts and chemically compatible construction.
  • Oil-free diaphragm technology avoiding oil contamination.
  • Electrical: configurable for wide input range (90–260 V AC) and 24 V DC options.
  • Low sound level: < 45 dB for quieter laboratory environments.
  • Quick-access components for simplified maintenance and service.


Applications / Use cases
  • Conveying and compressing neutral and aggressive gases and vapours.
  • Generating vacuum down to ultimate pressure < 2 mbar for laboratory processes.
  • Suitable for physical and chemical laboratories, research facilities and similar chemical applications.


Scope of delivery
  • 4-head chemical diaphragm pump (MPC 105 T).
  • Integrated motor protection switch.
  • Hose nozzle DN 8 (for 8 mm inner diameter hose).
