Dry
Compressing Screw Vacuum Pumps
 |
The ScrewLine and Dryvac families of pumps were developed for industrial
applications. Available with pumping speeds of 250-300 m3/h
and 630 m3/h, screw type pumps are extremely reliable, compact
and low maintenance. ScrewLine pumps are extremely rugged, able to ingest and exhaust up to
1 l/minute of liquid from your process and highly tolerant of
particles. They are available with the SP Guard system
for constant monitoring of the operational status. Parameters can be
read from a display or output to a PLC.
All models from the DRYVAC®
platform have been designed and adapted to the special needs of
applications in the photovoltaic
production chain and to the process
industry in general. DRYVAC pumps and
system combinations are rugged, reliable and durable, ready to fulfill
stringent process requirements. |

Dry
Diaphragm Vacuum Pumps
This range of vacuum pumps was developed especially for
laboratory operations and as backing pumps for (wide
range) turbomolecular pumps. It satisfies the highest expectations in
terms of precision, reliability and ease of use. The DIVAC line of vacuum
pumps is the logical continuation of diaphragm pump technology which has proven
its quality in decades of service.
 |
Laboratory Pumps
Through the laboratory pumps and the three different pumping speeds
available for the same base pressure and through the modular design, the
optimum DIVAC L pump system 1) can be implemented in each case. |
|
Laboratory
Pumps Features and Benefits
| Low base vacuum of 8 mbar (100
mbar for single-head DIVAC pumps) |
|
All parts of
the pump head in contact with the gas are resistant against aggressive
media through the use of PTFE (Teflon), FFPM (Kalrez) and PVDF (Solef) |
|
Dry
compressing, oil-free |
|
Very high
water vapour tolerance |
|
Low
maintenance costs and long service intervals through the use of
high-quality components which are well-proven |
|

relocation since the entire assembly is mounted as a unit on a stable
base plate for easy transportation |
|
Individual
components with plug connectors for easy removal and mounting |
|
Compact
design – Small footprint |
|
For the SC
configuration – with separator, high-performance condenser and
controller – all electrical connections are arranged inside the
control unit and made by way of plug connectors |
|
Trouble-free
provisions for mounting additional laboratory equipment in grooved
rails, on laboratory stands and crossbars in the assembly |
|
Simple
replacement of diaphragms and valves on the vacuum pumps |
|

Backing Pumps
The DIVAC T range of diaphragm pumps comprises
backing pumps which are used in all applications requiring an especially
low base pressure while having to maintain an oil-free vacuum. The
DIVAC T pumps have been specially developed as backing pumps for wide
range high-vacuum turbomolecular pumps. They meet the requirements for a
dry vacuum and a long service life. DIVAC T pumps may be used both
free-standing and integrated in applications or certain devices, and for
this reason they are used in the areas of mass spectrometry, analytical
and in general applications. The DIVAC TC
pumps are capable of handling aggressive and corrosive gases as
encountered in research or in connection with sputtering processes. The
parts of the pump in contact with the medium are made of PTFE (Teflon),
FFPM (Kalrez) and PVDF (Solef), and for this reason the pumps are highly
resistant to the media mentioned. |
