1. Fields of Application Suitable for a wide variety of offshore services to pump clean or slightly loaded liquid (water, sea water...):

• Cooling of main and auxiliary engines • Bilge • Ballast • Fire fighting • Cargo tanks cleaning • Brine circulation • Deck washing • Cooling and air conditioning

ILN-ILNC Pumps can be used as well for onshore applications, specially suited where there are space constraints

For pumping hydrocarbons please contact KSB ITUR since special material variant may be required.

For any specific application beyond these limits, please consult KSB ITUR. All data given in this document are for fully standard construction.

3. Design Vertical, volute pump casing with in line suction and discharge flanges. Single stage, closed impeller with single or double suction depending on pump size (check table below). Equipped with renewable wear rings in pump casing and cover. Pump is for vertical installation.

ILN pump size Impeller type 65/--- up to 250/--- single suction ≥ 300/--- double suction ILNC pump size Impeller type all single suction

When an S letter is added to the ILN and ILNC series, it means that the pump has an automatic priming system via an auxiliary liquid ring –priming pump (see point 15.1).

When an E letter is added to the ILN and ILNC series, it means that the pump has an automatic priming system via an auxiliary Ejector (see point 15.2)

6. Components

6.1 Shaft Seal Single mechanical seal acc. to EN 12756 (DIN 24960) is supplied as standard.

6.2 Drive As standard, surface cooled IP-55 IEC frame electric motor with standard construction IM 3011 (IM V1).

6.3 Bearings / Lubrication The ILN series with single suction (see point 3) impeller incorporates a bearing bracket with two bearings greased for life.

The ILN series with double suction (see point 3) impeller incorporates one bearing greased for life and a friction bearing bush lubricated by pumped media.

The ILNC series (compact) has a bearing bracket with one ball bearing greased for life.

6.4 Coupling The ILN series with single suction impeller (see point 3) incorporates a flexible coupling with a spacer.

The ILN series with double suction impeller (see point 3) incorporates a flexible coupling without spacer. For this case the option of coupling with spacer is available (option marked with D letter).

The ILNC series (compact design) includes a rigid coupling.

Coupling Guard: Metallic protections are supplied as standard.
