Leading pumps and Valves manufacturer, KSB has developed its ILN type series of vertical in-line centrifugal pumps to meet the stricter limits on the sulphur dioxide content of marine exhaust gases stipulated by the EU and International Maritime Organisation (IMO) which come into force in 2020.

The pumps, from KSB ITUR Spain, meet the tough requirements regarding operating behaviour and efficiency specified by the authorities to curb global marine and air pollution. This can be achieved by using natural gas or fuels with a low sulphur content and by cleaning the exhaust gases with a scrubber.

The design allows the impeller to be dismantled without removing the piping and motor and a self-venting wide mechanical seal chamber ensures durable sealing at the shaft passage. Replaceable casing wear rings in the pump casing and casing cover make servicing straightforward.

The water-tight rolling element bearings do not need re-lubrication or maintenance. The maximum flow rate of the (60 Hz) pump sets is 3700 m³/h and the highest head is 160 m.

According to an estimate by the Exhaust Gas Cleaning Systems Association (EGCSA) only 1000 vessels at sea are currently fitted with a scrubber or prepared for such an installation.
