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) 4.

Components 6.1 Shaft Seal Single mechanical seal acc. to EN (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. 7. Product information according to Regulation 547/2012 (for waterpumps with a maximum shaft power of 150 kw) based on Directive 2009/125/EC Ecodesign Directive Minimum efficiency index (MEI) see the name plate The benchmark for most efficient water pumps is MEI 0,70 Construction year: see name plate Manufacturer name or plant mark, commercial registry number and manufacturing place: see datasheet and order documentation Type and product size indications: see name plate Hydraulic efficiency (%) with a trimmed impeller: see datasheet Pump performance curves, efficiency curves included: see the performance curve from the documentation The efficiency of a pump with a trimmed impeller is usually lower than that of a pump with the full impeller diameter. The trimming of the impeller will adapt the pump to a fixed duty point, leading to reduced energy consumption. The minimum 2

3 efficiency index (MEI) is based on the full impeller diameter. The operation of this water pump with variable duty points may be more efficient and economic when controlled, for example, by the use of a variable speed drive that matches the pump duty to the system Information on dismantling, recycling and disposal, see chapter 3.3 Information on benchmark efficiency and benchmark efficiency graph for MEI = 0,7 (0,4) for the pump based on the model shown in the figure is available on: 8.

Priming systems 16.1 Priming system by auxiliary pump VAC rear view Mark Denomination Size To be connected by customer 1 Check valve Filter Electrovalve V II + earth 50/60 Hz 4 Auxiliary priming pump Discharge air/water 3/4 G (F) Leave connection free or connect to a safe 6 Pressure switch (on discharge of main pump) --- drainage Start-up: 0,4 bar Shutdown: 70% of the operating pressure of main pump or min. of the pressure switch Note The electrical control devices of the auxiliary priming pumps are not within the scope of supply of KSB ITUR, except for the case of being expressly requested (see recommended electrical layout) Operation Note When starting up the unit, the auxiliary priming pump starts up and electrovalve opens, beginning to extract the air existing in the suction pipe. After a period of time T1 the main pump starts up, with both operating simultaneously. When the water reaches the main pump, the pressure increase is detected by the pressure switch, switching on a second timer, which switches off the auxiliary priming pump and the electrovalve after a period of time T2 In case a depriming happens in the facility, the pressure switch detects the pressure drop and starts up the auxiliary priming pump (the main pump remains in operation). The start-up time (T1) of main pump depends on the volume of air to be discharged. During priming tests it must be adjusted experimentally to the minimum. T2 shutdown time depends on any instability which may come about during start-up The VAC auxiliary pump is not designed for Note continuous pumping of water without air. That is why if T2 time is excessive, the motor of the auxiliary pump may be overheated. Thus adjust T2 to a few seconds ( 5 sec.) or to star-delta start-up time. In any case, the total time that the auxiliary pump works only with water shall not exceed 15 sec. Installation The discharge of the auxiliary pump (mark 5) should not be closed or impeded. When the pumping liquid is water, the maximum installation height on the lowest level of the liquid must not exceed 6 m, minus the dynamic losses of the suction system. Start-up Bear in mind the following points when starting up: - Check all the connections and the pipes to ensure seal tightness. - Prime the auxiliary pump, if it is first start-up - Check all the electrical connections. 23

After a period of time T1 the main pump starts up, with both operating simultaneously. When the water reaches the main pump, the pressure increase is detected by the pressure switch, switching on a second timer, which switches off electrovalves after a period of time T2 In case a depriming happens in the facility, the internal pressure switch of suction electrovalve detects the pressure drop and starts up the electrovalves (the main pump remains in operation). The start-up time (T1) of main pump depends on the volume of air to be discharged, although for installations with short suction pipes following orientative values can be used: Ø Suction pipe Time T1 < 50 mm 60 seconds 125 mm 120 seconds > 125 mm 180 seconds T2 ejector shutdown time depends on any instability which may come about during start-up and can be taken a value between 10 and 30 seconds. Installation The discharge of ejector (mark 6) should not be closed or impeded. When the pumping liquid is water, the maximum installation height on the lowest level of the liquid must not exceed 6 m, minus the dynamic losses of the suction system. Start-up Bear in mind the following points when starting up: - Check all the connections and the pipes to ensure seal tightness. - Check all the electrical connections. 25
