2 02 The reliability of one brand for the most demanding requirements KSB is the leading manufacturer of pumping equipment for fire protection (FP) in Spain. This leadership is not a coincidence but instead is based on an array of capabilities that make KSB an undisputed benchmark in the sector. Important contributing factors include the high technological standard of our designs and our more than sufficient material and human resources to ensure faithful compliance with contractual rules and also with the mandatory regulations in the country of destination.

3 03 KSB pumps: FM approved split case pumps. Pumps certified according to the following standards: VdS, APSAD/CNPP, LPC, BMOKF, ZUZ/Pavus, CNBOP and APCI. Pumps according to EN 733 and ISO Vertical submerged pumps. Multistage pumps. KSB valves and actuators: APSAD/CNPP approved butterfly valves and actuators (up to 16 bar) and FM approved for higher pressures. Complete KSB pumping equipment for FP with pumps, electric motors, diesel engines, valves, manifolds, pressure switches, and handling and control panels - according to the most demanding standards: FM, NFPA-20, UNE 23500:2012, EN 12845, Cepreven RT2-ABA and RT1-ROC, VdS, NC, etc.

4 04 Pumping equipment description KSB manufactures pumping equipment for FP with two kinds of supply formats: UNIT Each UNIT consists of a main pump, with its electric motor or diesel engine and diesel tank and batteries, coupling, baseplate and control panel. Optionally, the pressure maintenance pump (jockey pump) and its control panel can be mounted on the same baseplate. In no case does the unit include valves or a general manifold. SET Each SET consists of one or various main pumps, with their electric motor or diesel engine and diesel tank and batteries, coupling, common baseplate, control panels, shut-off and check valves, concentric diffusing cones, pressure switches, pressure gauges, general discharge manifold, hydropneumatic accumulator and accessories. Optionally, the flowmeter can be supplied separately, as can the testing assembly made up of the manifold, the isolation valves for each main pump and the flow control valve.

5 05 Applicable standards KSB manufactures pumps and valves that are certified by the following organisations: Each fire pump must comply with very specific requirements. First, there are the different methods of fighting fires. These include sprinkler systems, fire hose reels (FHCs), outdoor hydrants, foam, water spray and water mist, etc. In addition to handling the differences in application, the pumps must also comply with different national and international approval regulations. KSB s comprehensive programme can always provide the right solution for your needs. With this in mind, our equipment is manufactured in accordance with the standard required for each case, either because of the official requirements of the country, or because of contractual requirements. The most common standards are: KSB Fire Protection Series UNIT SET NFPA-20 Non listed FM Global UNE EN UNE Cepreven RT2-ABA Cepreven RT1-ROC CEA 4001 Other APCI - VdS...

The tower houses a 39,000 m² office complex with KSB products for various services, including the fire protection systems. The French architect Jean Nouvel designed the Torre Agbar in homage to the famous Catalan architect Antonio Gaudí ( ). Submerged vertical pump

8 08 Construction details In terms of construction, the SET class of pumping equipment is the most complete since, in addition to the pumps with their motors and fully-wired control units, this class includes an individual bypass for testing, pressure switch and pressure gauge assemblies, general discharge manifold, common baseplate, hydropneumatic accumulator, valve systems and accessories Jockey pump 2 Main pump with diesel engine 3 Main pump with electric motor 4 Common baseplate 5 Pump-motor coupling 6 Battery set 7 Diesel emergency start-up panel 8 Complete motor wiring (control panel, sensors) 9 See detail on page 9 10 Diesel tank sensor 11 Diesel pump control panel 12 Diesel tank 13 Water-water heat exchanger 14 Diesel engine exhaust silencer 15 Jockey pump pressure switch and pressure gauge 16 Electric pump control panel 17 Hydropneumatic accumulator connection 18 General discharge manifold 19 Heat exchanger circuit 20 Pressure reducer valve for the heat exchanger

9 09 Differentiating details KSB pumping equipment complies with the standards for which it has been designed down to the smallest detail Independent bypass for testing on each pump 22 Valve with gear reducer, visual position indicator and electrical contact for remote monitoring 23 System for independent testing of pressure switches with purge valve 24 Main pump discharge pressure gauge 25 Pressure relief valve 26 Pressure switch to confirm pressure with pump operating 27 Main pump start-up pressure switches (in series) with temporary disable button Each main pump has a set of pressure switches at the discharge outlet. There is also a pressure switch located before the check valve to confirm that there is pressure at the pump oulet when it is required, and two pressure switches with normally closed contacts connected in series, so that the opening of the contact of any of them or wire break causes the start up of the main pump.

10 10 Materials and testing complying with the standards Materials for the main parts of the pump: KSB model BOAX-B valves for the main pumps. These are butterfly valves with a reducer and flywheel, clearly identifiable position indicator, chain with a padlock to fix the position and 2 contacts for electrical supervision: fully open and fully closed. Impeller cast in a single piece in bronze or stainless steel depending on pump size. Bronze or stainless steel wear ring. Shaft sealing by gland packing. Stainless steel shaft sleeve. The pump start-up and control panels faithfully meet the specifications of the standards for which they are designed. They are all wired and numbered according to the attached diagram and are tested at KSB. Jockey pump control includes delayed pump stop after order reception. In the control circuit of the electric main pump, which is protected by fuses, the starters are fed at the nominal voltage between mains phases (400 V), and not at the reduced voltage taken between phase and neutral.

11 11 Standards UNE 23500:2012 and EN power for NPSH up to 16 m European standards (EN 12845, UNE 23500:2012, CEA 4001, Cepreven RT1- ROC, etc.) require that motor power must be greater than or equal to the maximum power consumed by the pump at any point on its characteristic Q-H curve. To determine how the maximum power consumption has to be calculated, the standards distinguish between two types of pump according to their power consumption curve: Type A curve Type B curve A. The power consumption increases as the flow increases, until it reaches a maximum value, and then decreases as the flow continues to increase. This is typical of pumps with semi-axial impellers. B. Power consumption continuously increases as the flow increases. Typical of pumps with a radial impeller. In accordance with European standards, KSB guarantees correct selection of the motor's useful power, in kw, by showing the entire curve for pump operation up to an NPSHr of 16 m. Nominal point: Qnb = 170 m 3 /h; Hn = 62 m Overload point: 1.4 x Qnb = 238 m 3 /h; H = 52 m (>62 x 0.7) Is maximum power consumption 45 kw? NO. This only appears to be the case if the coloured area with the complete curve for the pump is not shown until it reaches a positive suction threshold of 16 m. In fact, the maximum power consumption is 55 kw. We will therefore require a motor, control panel, cables, transformer, etc., for 55 kw

12 12 Test benches Reliable proof KSB test benches are equipped with state-of-the-art measurement and control technologies. KSB Spain has modern test benches to test pumps from 0.5 to 710 kw at different speeds, having a frequency converter for all the power ratings. With the test benches that KSB has in Europe, pumps with a power of up to 20 megawatts (MW) can be tested. By means of large stainless steel tanks that can be subjected to a vacuum or pressurized up to 4 bar, measurement of required NPSH (between 0.3 m and 49.0) m can be carried out in the KSB test bench in Zarautz. The test bench is fully automated. All valves are piloted and operated from the control room or even from Germany or another KSB Group test bench via the Internet. The results are produced automatically. The test bench that KSB has in its factory in Zarautz (Spain) has the following facilities: Surface area: 1,000 m 2 No. of benches: 9 Installed power: 1,600 KVA Speed: variable using frequency converter Q per pump: up to 4,500 m 3 /h H per pump: up to 400 m (40 bar) DN max: DN 600 Minimum NPSH: 0.3 m Maximum NPSH: 49 m Inspection with complete protocol: up to 75 b/day
