Kalrez® perfluoroelastomer parts provide best in class chemical resistance for exploration and production services while also meeting the industry standard requirements.
Kalrez® Spectrum™ 7275 seals allowed to extend the pump seal life to more than 12 months. |
|
Kalrez® Spectrum™ 7275 as the preferred elastomer for mechanical seals of pumps handling aggressive silanes and chlorosilanes. |
|
While the incumbent FFKM O-ring showed signs of severe swelling and blistering, Kalrez® Spectrum™ 7275 seal had only superficial color change, with minimum swelling and unchanged flexibility. |
|
Kalrez® Spectrum™ 7275 O-rings extended the Mean Time Between Repair (MTBR) of this mechanical seal by at least 30%. |
