G 1 – DN 40

Sealing
  • Separating can / Magnetic drive
  • Mechanical seal

Advantages
  • Developed/designed for continuous operation
  • Requirement-related design due to variation of individual components such as motor, coupling, base plate, etc.
  • Requirement-related design due to the use of diverse materials
  • With a maximum sound pressure level of 60 to 66 db(A) much more quiet than a conventional liquid ring vacuum pump
  • VZ 110 / 140 / 180 are alternatives to VH series due to identical connection dimensions

Applications
  • Extruder degasification
  • Sterilization of surgical instruments, textiles and beds (steam- and gas sterilization)
  • Degasification of toothpaste, cremes, lotions, marzipan etc.
  • Vacuum cooking of fruits, vegetables, pulps and mush
  • Thickening and crystallisation of sugar under vacuum
