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.
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.
For the entire SealPro range the new material SSIC with graphite filler is now available as an option. (SSICG)
- Better chemical resistance, specially with very corrosive alkaline and etching acids.
- Dry running abilities are improved by using graphite filler in the SSIC/SSICG
- Less wear in situations with chapped liquids.
- 100% exchangeable with the old parts. This option can even be used in existing pump models with impellers provided with pressure release bores.
