• Ensures maximum operating reliability with KSB mechanical seal featuring a multi-spring arrangement and reliable venting during pump operation.
• Incorporates safety barriers including a special contour for reliable leakage removal at the mechanical seal, confined sealing elements, and an effective heat barrier.
• Meets individual requirements with maximum efficiency and reduced operating costs through impeller trimming, variable speed operation, intelligent control by KSB frequency inverters and KSB motors up to IE5, maximum hydraulic pump efficiency, and low NPSHreq.
• Offers a wide range of applications due to compliance with EN PN16 and ASME standards, ATEX-compliant versions, carbon plain bearings, various marine versions, and a fan impeller for efficient cooling.
• Provides great ease of maintenance with casing wear rings and a back pull-out design, allowing the casing to remain in the piping during maintenance.
