VZ series
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...
