Product development SealPro KR series BG2-3 | new mechanical seals

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.

This results in significant improvement in load capacity, wear resistance, friction coefficient etc.  Each micro-dimple can serve either as a micro-hydrodynamic bearing in cases of full or mixed lubrication or as a micro-reservoir for lubricant in cases of starved lubrication in a dry running situation.

The old seal configuration SIC/SIC had equal seal materials and fine polished seal faces. In some situations, it was possible to get a kind of adhesion effect between the seal faces, in particular after a longer period of running in combination with drying out of the medium between the seal faces.
Other advantages of the new SSIC seals:

• Parts are 100% interchangeable with the old parts
• Can be used in existing pump models with impellers which are provided with pressure release bores
• No price adder, but with increased performance!
