3 Fire CRFF. Introduction to VdS VdS Schadenverhütung GmbH is an independent, international, accredited and notified testing and certification institution for fire prevention and safety technology as well as for physical and electronic protection against intrusion. ("Schadenverhütung" is the German word for "loss prevention"). VdS Schadenverhütung is accredited according to the EN 45 series of European standards and is a member of the European Fire and Security Group (EFSG). VdS experts are represented in all relevant German and international committees. The concept behind VdS recognition is to ensure that only tested and certified products and services are offered to the safety and security markets. This is equally advantageous for user and supplier. For further information on VdS, see Introduction to VdS VdS standards The products in this data booklet have been built to comply with VdS standards on water-based firefighting systems, described in the following documents: VdS CEA 4-S:23-: Planning and installation. VdS 2-7: Guidelines for water-based firefighting systems. VdS 2344: Procedures for testing and approval of equipment, components and systems used in fire protection and security control. Standards approval process Grundfos is to test the pumps and fill in the application forms for each individual pump size. The following documentation should to submitted to the VdS: complete drawings with list of parts and materials of the major components a statement regarding quality and production (ISO 9 + Annex A & D) data sheet with technical information installation and operating instructions. If the application forms are accepted, VdS will attend the final test at the Grundfos premises. If the evaluation of the test results is positive, the VdS will issue a certificate on the approval of the pump. 3

9 Fire CRFF Fire pumps Grundfos centrifugal pumps approved by the VdS are designed for the distribution of water in stationary sprinkler systems using either foam or water spray. They are operated in case of fire and during tests. Materials VdS-approved pumps must comply with these requirements: impeller, wear rings and wet parts such as shaft, washers and nuts must be made of non-corrosive iron. castings must be made of EN-GJL-25 cast iron. VdS requirements for EN-GJL-25 do not allow heads (H) above m and flow rates (Q) above 6 m 3 /h. Above m ductile iron is required. Pump characteristic The VdS focuses strongly on the instabilities which may be present in sprinkler systems consisting of long and different pipe circuits. Two instable pumps may cause vibrations or breakdown. If the characteristic is instable, the instability must not exceed 5 %. See examples of instable (fig. ) and stable (fig. 2) characteristics below.

See fig. 3. The duty point of the pump must not be to the right of this limit. Q zul is defined on the basis of the pump NPSH curves. The following calculation must be made for the largest and smallest pump impeller diameter.

Pressure stage Operating pressure Test pressure bar MPa bar MPa PN. 5.5 PN Construction Installation Pipe connection When installing the pipes, make sure that the pump housing is not stressed by the pipework. The suction and discharge pipes must be of an adequate size, taking the pump inlet pressure into account. Install the pipes so that air locks are avoided, especially on the suction side of the pump. See fig. 4. TM Fig. 4 Pipelines Fit isolating valves on either side of the pump to avoid having to drain the system if the pump needs to be cleaned or repaired. Make sure the pipes are adequately supported as close to the pump as possible, both on the suction and the discharge side. The counter flanges should lie true against the pump flanges without being stressed; otherwise, the pump will be damaged. 5

The NPSH curve is according to the minimum and maximum impeller diameter. TM Curve conditions Selection of pumps The guidelines below apply to the curves shown in the performance charts, pages 25 to 3. Tolerances according to ISO 996 and VdS 2-7. The curves show pump performance with different number of impellers at the nominal speed. The bold part of the curves shows the recommended operating range. The thin parts are not allowed according to the VdS. Do not use the pumps at minimum flow rates below. x Q at optimum efficiency because of the danger of overheating of the pump. The curves apply to of water at a temperature of +2 C and a kinematic viscosity of mm 2 /s ( cst). NPSH: The curves are according to the minimum and maximum number of impellers. In case of other densities than kg/m 3 the discharge pressure is proportional to the density. When pumping water with a density higher than kg/m 3, motors with correspondingly higher outputs must be used. Calculation of total head The total pump head consists of the height difference between the measuring points + the differential head + the dynamic head. H = H + H + H total geo stat dyn H geo : Height difference between measuring points. H stat : Differential head between the suction and the discharge side of the pump. H dyn : Calculated values based on the velocity of the pumped water on the suction and the discharge side of the pump. 23

24 3 Fire CRFF Construction Performance tests The requested duty point for every pump is tested according to ISO 996 and VdS 2-7. If the customer requires a specific number of impellers (not a specific duty point), the pump will be tested at a duty point which is 2/3 of the maximum flow rate of the published performance curve related to the ordered number of impellers (according to ISO 996). If the customer requires either more points on the curve to be checked or certain minimum performances or certificates, individual measurements must be made. Certificate The pump order includes a test certificate confirming the required QH performance. 24
