  • Fire NKFProduct description

    IntroductionGrundfos Fire NKF fire pump sets are typically used in firefighting applications for supplying water to fire hose reels, fire hydrants or sprinkler systems.

    This data booklet covers fire pump sets with electrically and diesel-powered NKF end-suction pumps.

    DesignationsFire NKF is an NKF end-suction pump with coupling and motor or engine mounted on a common base frame.

    The fire pump set can be incorporated into a firefighting system.

    DBI 251/CEA 4001 standardThe products in this data booklet have been built to comply with the DBI guidelines 251/4001 for sprinkler systems (design, installation and maintenance).

    Fire NKF pumpsGrundfos NKF pumps according to DBI 251/4001 are designed for the distribution of water in stationary sprinkler systems using water spray. They are operated in case of fire and during tests.

    MaterialsRequirements to pump materials according to DBI 251/4001:

    Impeller and wear rings must be made of bronze. Wet parts such as shaft, washers and nuts must be

    made of stainless steel. Cast parts must be made of cast iron.

    ControllerGrundfos offers a controller in a steel plate cabinet, suitable for wall mounting or free-standing installation.

    The controller complies with the standard DBI 251/CEA4001.

    The controller for pumps with electric motor can be mounted on the wall or on the base frame.

    The controller for diesel-powered pumps is always mounted on the base frame.

    Electric motorThe electric motor is an MG or MMG motor complying with local standards for electric motors. As from 16 July 2011, the motors used in Europe will be IE2 = EFF 1 motors.

    Fig. 1 Fire NKF: An NKF end-suction pump with electric motor and controller mounted on a base frame

    Insulation class: F.Enclosure class: IP55.

    Diesel engineThe diesel engine can operate continuously at full load at site elevation with rated output in accordance with ISO 3046-1:1986. The pump is at full operational speed within 15 seconds; the engine is capable of starting at a room temperature of 5 C.

    Fig. 2 Fire NKF: An NKF end-suction pump with diesel engine and controller mounted on a base frame

    Each complete engine and pump unit is tested on the manufacturers test bed for at least 1.5 hours at rated flow rate, and the result is recorded on the test certificate.

    Product description Fire NKF

    Other system componentsJockey pumpsGrundfos CR pumps are used as jockey pumps, maintaining the water level in the pressure tank. Under normal conditions, the jockey pump is activated by the low-level switch in the pressure tank as a result of small leakages in the pipe systems filled with water. The jockey pump operates until it is deactivated by the high-level switch. The jockey pump can also be activated in case one or more sprinklers are open, in order to maintain the water level in the pressure tank.

    CompressorThe compressor can be set to manual or automatic operation by means of the selector switch.

    During automatic operation, the compressor is controlled by an external pressure switch, for example connected to the pressure tank.

    The compressor can be manually switched on and off.

    Scope of deliveryA complete Fire NKF unit assembled and supplied from factory normally comprises these elements:

    a pump and motor mounted on a common base frame

    a standard coupling protected by a coupling guard a controller according to DBI 251/CEA4001.

    CommissioningThe installer should commission the complete firefighting system before handing it over to the plant manager on site. Many potential issues of the complete system must be tested before commissioning to ensure a satisfactory system performance and identify any damage during installation.

    Key components should be checked according to the descriptions in the respective installation and operating instructions. In addition, DBI 251/CEA4001 stipulates that tests such as these should be carried out:

    pressure test of sprinkler circuits values of all measuring devices (air pressure, water

    level, etc.) to the system water flow to fire pumps test of alarm system and interface to municipal fire

    department.The installer should supply the plant manager with the following documents:

    Installation certificate, stating that the firefighting system has been installed according to DBI 251/CEA4001 requirements.

    A complete set of installation and operating instructions and system drawings with specification of all components for the plant manager and the owner of the system.

    Product description Fire NKF

    Pump characteristicsDBI 251/4001 focuses strongly on the instabilities. This is due to 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. 5) and stable (fig. 6) characteristics below.

    Fig. 5 Instable pump characteristics

    Fig. 6 Stable pump characteristics

    Duty rangeThe maximum permissible flow rate is defined on basis of the pump NPSH curves. The flow rate must not exceed the flow rate found at 5 m NPSH.

    Fig. 7 Maximum permissible flow

    Power ratingTo ensure that the motor (electric motor or diesel engine) is capable of operating the pump at any time, thus ensuring water supply, DBI 251/4001 stipulates an excess capacity of motor power.

    According to DBI 251/4001, the motor power is found at 16 m NPSH. The example below show a required motor size of 22 kW.
