DIABON®, DURABON® andexotic metal pumps↑ DIABON centrifugal pump

↑ Exotic metal propeller pump

Centrifugal pumps
Thanks to our material expertise we deliver solutions that outperform standard pump constructions and help generate thelowest cost of ownership.

Axial pumps
Specially designed to improve the performance of evaporation
loops in the phosphoric acid industry, we offer exotic metal
axial pumps based on titanium, zirkonium and nickel alloys.

Graphite beats
Unlike plastic centrifugal pumps, DIABON graphite is neither
permeable nor loses stability over time or at high temperatures. Even accidental dry runs, temperature peaks or otherprocessing irregularities do not damage the pump. DIABON
pumps are vacuum resistant, compatible with almost all
corrosive fluids and extraordinarily durable.

Unreached performers
These pumps allow flow rates up to 20000 m3/h and top heads
up to 10 m, even at low speeds. The welded constructions permit higher stability and purity than casted designs, while theoutstanding shaft rigidity induces low tolerances resulting inhigher efficiency. Moreover, the pumps are much less sensitive
to pressure changes or vibrations.

Your key benefits• Efficient
Low thermal expansion and absence of swelling allows
for very low tolerances and constant performance overyears, even up to 200 °C• Durable
No permeation of corrosive fluids and resistance against
nearly all chemicals

Resistance at its best
The high corrosion resistance results in significantly lower
maintenance costs compared to other pumps. In fact we are
one of the very few manufacturers of pumps that are capable of working in phosphoric acid. Our axial pumps are used
in industries that employ fertilizers/phosphates, potash andsulphuric acids, and are also available in various carbon materials.

• Abrasion resistant
DIABON has a good resistance to abrasion at elevatedtemperatures. With hard DURABON carbon and free-flow
designs we offer solutions that stand up to even the
toughest conditions• S tandardized
Designs according to ISO 2858
• Maintenance-friendly"back-pull-out" design allows inspection andmaintenance without disconnecting the piping and volute

DIABON® quenchers

Robustness and efficiency
Our graphite-based quenchers are an excellent choice for thetreatment of gases in an aggressive chemical environment(e.g. where acids can be generated), and also can withstandgas temperatures up to 1600 °C. Their design, with no moving parts, is extremely robust and is not affected by thermal
shock or deformation, while impairment by dust particles isminimized. These are prerequisites for excellent production
efficiency.
Pipe quenchers for high heat transfer rates
In this design, liquid and gas flow co-currently through pipes
at high velocities. The turbulences created thereby ensure
prolonged direct contact and thus high heat transfer rates,
while they also reduce the risk of plugging, thus enhancing theeffect of large pipe diameters.
Empty pipe quenchers reducing the risk of foulingIn these quenchers the cooling liquid forms a conical curtain
which directly acts on the gases flowing through the pipe. This
design eliminates the risk of fouling (with particles up to 2 mm)
and is especially helpful when low pressure drops are indispensable or capacity fluctuations occur.

Your key benefits• Flexible
High turndown up to 100%, fast start-up and shut-down,
insensitive against varying flue gas composition• Installable
Compact design due to direct contact heat transfer andoptimized free flow cross section• Reliable
Stop of high temperature reactions by sudden reductionof process gas temperature• Durable
Long lifetime due to robust design and use of first grade
graphite material DIABON

Upgrading your equipment
We also supply materials and designs to improve the temperature- and corrosion resistance of your units in case you do not
operate with DIABON-based quenchers.

DIABON® rupture disksMore control – more reliability
Our rupture disks, made of high-grade graphite for processequipment, steadily burst at the rated pressure. Due to the homogenous structure of the material, constant strength is maintained all over the disk, only rupturing when pressure reaches
the critical value.

Conversely, our rupture disks made of synthetic resin-impregnated graphite (series N, D and DV) do show influence of temperature, but this occurs only above 50 °C. Yet their reliability isclearly higher in comparison to metal disks, as DIABON graphite
rupture disks exhibit a much smaller drop in bursting pressure
with a rise in temperature.

Ring flanges for additional safety
On request, our disks (series N, F and HT) can be supplied witha carbon fiber-reinforced ring flange. This reduces the risk ofrupture due to assembly errors and minimizes the likelihood of
media escaping after the safety disk is released.
Instant release of pressure
A further major advantage lies in the optimized brittleness ofthe material. Thanks to this, our DIABON graphite rupture disks
instantly free the entire pressure release aperture on bursting.
Resisting temperature rises
While the conformity to rated bursting pressures in metal
rupture disks generally declines as temperature rises, our disk
series F and HT remain unaffected by heat. The mechanicalstrength of the disks doesn’t alter over the entire permissible
temperature range.

Your key benefits• I ndependant

Setting the benchmark
Whenever materials like stainless steel or plastics
do not cope with aggressive environments (such as
corrosive or high temperature situations), carbon
fiber composites (CFC) provide a highly resistantalternative.
Our SIGRABOND Chemical carbon-fiber reinforcedcarbon for column internals excels in lightness,
stiffness and strength, resists much higher temperatures than plastic and is at a lower cost level
than special metals.
For these reasons, a leading company for separation and mixing technology decided to extend theircooperation with us in the field of column internals. As a result, we deliver a unique and complete
portfolio that includes support grids, packing, liquid
distributors, collectors and feed pipes made of
SIGRABOND Chemical.
For the first time, an entire family of CFC-based
column internals is available, allowing for the often
difficult combination of different materials to be
avoided. Moreover, an innovative connection system enables the realization of larger diameters andallows for cost-efficient production.
