Cool solutions for hot issues There are two major reasons why it is imperative to pay close attention to the fire protection solution in the buildings. The first reason is obvious: high quality fire prevention provides the best safety guarantee for the people who use the building and the environment that surrounds it. The second reason is more pragmatic: having high quality fire prevention severely reduces the cost of insurance premiums. In Germany alone, around 150,000 fires a year cause damage worth more than 2 billion. And insurance companies give discounts of up to 65% to public facilities and commercial buildings that install the best stationary fire protection systems. At Grundfos, we have more than 60 years of experience in pump applications. Read on to find out more about our fire prevention solutions and be inspired to leave fire prevention to our experts. The systems of choice Stationary fire protection systems provide the preferred way of protecting commercial buildings and public facilities. Most of the stationary systems work with water, which is available in sufficient quantities almost everywhere and is an excellent extinguishing medium. In the stationary protection systems, sprinkler systems distribute a fine spray of water over a large area, which cools the fire seat and fights the fire. The water also absorbs released gases, soot, and other harmful substances. Grundfos has firepumps that fullfill the VdS standards an internationally recognized standard of sprinkler systems. Our fire pumps are also available on request with all other major international certifications. 2 3
Design and materials Sprinkler pumps are distribution pumps which pump water through stationary sprinkler systems using water spray or foam. They may only be put into operation in case of a fire or for testing purposes. By way of a minimum requirement, their castings must be manufactured from grey cast iron. Impellers and their attachments, shafts, and shaft sleeves must be made of non-rusting materials. To guarantee the shortest possible repair times, all key functional components must be replaceable using appropriate means at the site of installation. Installation, commissioning, regular testing The power supply for alarm and drive systems must feature a redundant, uninterrupted design. Approved fire pumps must only be fitted, commissioned, and serviced by certified installation engineers. Operators of fire protection systems must appoint a responsible person and a deputy. Routine inspections, functional tests, and annual maintenance work must be regularly carried out and the results recorded. The insurance company must be informed if the system is taken out of service for any reason. Characteristic curves, flow rate, head, NPSH Like any hydraulic system, fire extinguishing systems feature a performance range in which the operating points for maximum and minimum pressure and for maximum and minimum flow rate are defined. To ensure optimum coverage of all points, the hydraulics in fire pumps are designed to achieve a stable (+/- 5% of H max ) and flat characteristic curve. When pumping the approved flow rate, the 4.5 m NPSH value must not exceed 5.5 m at 1.2 Q zul. Flow rates and heads are determined and tested by the VdS in accordance with DIN 1944 Accuracy Level III, taking into account the VDI flow regulations contained in DIN 1952. The performance data of pump and drive motor are stated in test records and on the name plates. Head H [m] 110 100 70 60 50 40 20 10 5,5 4,5 0 Max. pressure at closed valve Nom. operation point Q = 100 %, max. 600 m 3 /h Max. operation point NPSH max. 5.5 m NPSH curve Meeting the demands 0 100 120 Flow Q [%] The Grundfos fire pump range includes quality pumps for every VdS basic range. In order to fully live up to the standards, strictly defined requirements must be met regarding three areas: Design and materials Curves, flow rates, heads and NPSH curves Testing, installation and commissioning For more details on the specific requirements, please contact your local Grundfos company.

The diagram to the right indicates the appropriate pump for your system at the point where the flow rate and the head intersect. Besides the standard sizes in the diagram, Grundfos also provides intermediate sizes or any individual operating point on request as customised solutions. Simply ask the specialist in your local Grundfos company for expert advice. 100 70 50 40 20 50-200 2960 min -1 65-200 2960 min -1-250 2960 min -1-200 2960 min -1 150-500 10 min -1 150-400 10 min -1 150-400 1700 min -1 150-400 1600 min -1 150-400 14 min -1 20 40 50 60 100 150 200 0 400 500 600 0 Q [m²/h] 6 7
Three steps to more safety Step 1 professional advice The highest level of safety comes from involving the highest level of knowledge in your project from the beginning. A precise risk analysis and professional technical advice will help you decide exactly what your needs are. Consult your adviser and your insurance company and you are on the right track to safety. Step 2 redundant systems If you want the very best fire prevention, step 2 is to use redundant fire protection systems. Redundant systems are equipped with two fire pumps that each have the capacity to supply water to the connected sprinkler systems in case of an emergency. That means that you are guaranteed the best possible safety in every situation. Redundant systems double the protection and eliminate the worries.

They allow for a more flexible system that is not dependent on two different electrical power sources. The ideal pump combination in redundant systems is an electrically-driven pump combined with a diesel-driven pump. * 8 *9

We use this system when the space is tight or doors and corridors are too narrow to bring through the traditional pump systems in which pumps, control cabinets, and manifold are d W3 directly fitted to a single base plate.
