优势（Advantages）：
1. Designed to withstand mineral and synthetic hot oils up to 350°C
2. Extremely high operating reliability thanks to KSB mechanical seals with multiple springs and reliable ventilation solutions during operation
3. Safety barriers: Centrifugal/annular profiles ensure reliable drainage of leaks in mechanical seals, cavity seals and efficient thermal barriers.
4. Meet every need with maximum efficiency and reduce operating costs: trimmed impellers, speed regulation/intelligent control with KSB frequency converters and KSB motors up to IE5, highest hydraulic pump efficiency and low NSPH
5. Extensive range of applications thanks to EN PN16 and ASME standards, ATEX specifications, graphite plain bearings, DNV-GL offshore specifications and fan impellers for efficient cooling
6. Optimum maintenance thanks to pump body sealing rings and back pull-out design, which allows the housing to remain in the device during maintenance.
