Advantages 
  • 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
  • low investment costs
  • 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

Possible applications
  • sterilization of surgical instruments, textiles and beds (steam and gas sterilization)
  • extruder degasification
  • degasification of toothpaste, cremes, lotions, marzipan, etc.
  • vacuum cooking of fruit, vegetables, pulp and mush
  • thickening and crystallization of sugar under vacuum
  • distillation / separation of liquids...
