Order number: PP W73 400

  • High-performance Roots pump with a pumping speed of 2160 to 5190 m3/h
  • Blocked overflow valve
  • For operation with frequency converter or switch-on at a defined backing pressure, i.e. for continuous processes
  • With 3-phase motor II 2G Ex de IIC T4
  • Pumps are hermetically sealed (leak rate <1 · 10-6 Pa m3/s) - risk of zone entrainment is minimized
  • Pressure surge resistance according to EN 1333, PN level 16
  • Explosion safety due to reliable construction and temperature monitoring – installation without additional flame arrester possible
  • Note: For the operation of the pumps, the terms of the operating instructions apply. We are pleased to provide you with the right solution for your application!
  • Working conditions: Pump is inside and outside suitable for operation in equipment class II, equipment category 2 (G) for gases and vapors of explosion class IIA and IIB, temperature class T3 according directive 2014/34/EU
