KSB Itur IL Series

First-generation vertical in-line centrifugal pumps built to the DIN 24255 standard, widely fitted on vessels built in the 1990s and early 2000s for space-critical cooling and ballast transfer duty. Their in-line suction and discharge connections allow direct installation into straight pipe runs, saving valuable floor space in engine rooms and pumping stations.

The standard IL and ILS executions use a flexible spacer coupling between pump and motor, enabling back pull-out maintenance: the impeller, shaft, and mechanical seal can all be serviced without disturbing the suction or discharge piping. Where headroom is tight, the close-coupled ILC and ILCS executions mount the pump directly to a rigid motor frame instead, trading the spacer coupling for a shorter footprint while keeping the same ease of internal access. The ILS and ILCS executions add an integrated self-priming system, letting the pump clear air from the suction line and lift liquid from lower compartments on its own, with no manual priming or external foot valve required.
