Main advantages of this seal type are:
Our HiEff range with efficiencies up to 82% now is available in ATEX execution with maximum motor power of 90 kw.
Over the past years our range had been expanded with a bigger size with a maximum motor power of 18.5 kW!
Up till now, pumps for food applications where mainly restricted to metal pumps.
ARBO is constantly adding pump variants to enlarge the range. If you want most updated information that you will not find in your hardcopy catalogue, please try our selection program that always shows you all of our possibilities.

We thank you very much for your support and cooperation that made the year of 2018 very successful and we hope to continue our relationship next year in the same pleasant way!
The typical application of these pumps is the 24/7 application of chemically polluted liquids or salt water. With this as a starting point for the development, the target is to reach an energy consumption being the lowest of its kind.
For the SIC/SIC seal combination we developed a new surface structure and material combination of the seal faces. The combination of the two seal faces has changed into SSIC. One of the seal faces has a composite with graphite, giving improved dry running abilities and even higher chemical resistance to alkaline chemicals and acids The seal surface structure is provided with micro dimples, creating a capillary function.
As described above for the BG2-3 series the new seal configuration offers for the larger pump models of the BG 4 and 5 an increased system pressure to 6 bar. This due to the positive balancing of the seal. For applications with poor suction conditions (self-priming pumps, bad NPSHa, too small suction pipe diameters etc) we now can apply impellers without the pressure release bores.
