The optimized successor to the IL family, ILN Series is built for continuous marine duty pumping clean or lightly contaminated liquids: main and auxiliary engine cooling, bilge, ballast, firefighting, cargo tank cleaning, brine circulation, deck wash, and HVAC circulation. It's a vertical, volute-casing pump with coaxial in-line suction and discharge flanges, a single-stage closed impeller, and renewable casing and cover wear rings. Land-based use is possible too, though hydrocarbon service always needs a separate technical review for material compatibility.
Most sizes use a single suction; the two largest ILN frames (350-300-330 and 450-400-430) use double suction instead, while every ILNC size stays single-suction. The model code itself tells you the configuration: a plain ILN or ILNC is the standard build with no auxiliary priming; the S suffix (ILNS/ILNCS) adds an integrated liquid-ring vacuum pump for automatic self-priming, and the E suffix (ILNE/ILNCE) achieves the same with an air ejector instead. The rest of the part number spells out suction flange DN, discharge flange DN, nominal impeller diameter, and impeller hydraulic profile, in that order.
These reference numbers identify a part's position on the series diagram — the exact part fitted differs by model. To order, provide the reference number together with the model name and the serial number stamped on the nameplate.
