VARIO diaphragm pumps
for applications in chemistry and for powerful oilfree backing of modern wide range turbo pumps
Control your vacuum today with the technology of the
future
The VARIO pump system ...
... finds vacuum / distillation level
... adapts to temperature and composition changes
... controls with precision
... all automatically
... achieves the lowest ultimate vacuum of all
VACUUBRAND diaphragm pumps.
Advantages
process specific
- optimum flow rate independent of the system size and the vapour quantity
- automatic adaption of the vacuum level to the process (distillation,
drying, etc)
environmentally friendly
- optimum solvent recovery rate through continuous evaporation
- adaption when parameters change
- process requirements control vacuum and cooling water supply
- minimum cost of ownership
- reduced process time through high evaporation rates
- enhanced lifetime of the diaphragms
- minimized operating and maintenance costs
- very low ultimate vacuum
- extremly long maintenance intervalls
- totally oil free
with data communication
- serial interface
- input of required vacuum level from data processing systems
- data transfer to perform with routines or complex processes
Two Version
Aluminium Version:
Made of aluminium, FKM (e.g. Viton ® fluoroelastomers) and PE.
Chemical-Version "C":
All gas and vapour wetted parts are made from appropriate chemically resistant
fluorinated plastics.
