Fire NBF, Fire NKFProduct description
Introduction
Grundfos Fire NBF and Fire NKF fire systems are
typically used in fire-fighting applications for supplying
water to fire hose reels, fire hydrants or sprinkler
systems.
This data booklet covers fire systems with electric and
diesel-powered NBF and NKF end-suction pumps.
Designations
Fire NBF is an NBF end-suction pump with motor or
engine mounted on a common base frame.
Fire NKF is an NKF end-suction pump with coupling
and motor or engine mounted on a common base
frame.
The fire system can be incorporated into a fire-fighting
system.
EN standardsThe products in this data booklet have been built to
comply with EN standards on water-based fire-fighting
systems, described in the following documents:
• EN 12845: Fixed fire-fighting systems. Automatic
sprinkler systems. Design, installation and
maintenance
• EN 12259-12: Fixed fire-fighting systems. Pumps
for sprinkler and water spray systems.
Fire NBF and NKF pumps
Grundfos NBF and NKF pumps according to EN 12845
and EN 12259-12 are designed for the distribution of
water in stationary sprinkler systems using water spray.
They are operated in case of fire and during tests.
Materials
Requirements to pump materials according to
EN 12845 and EN 12259-12:
• Impeller and wear rings must be made of bronze.
• Wet parts such as shaft, washers and nuts must be
made of stainless steel.
• Castings must be made of cast iron.

Product description Fire NBF, Fire NKF
Pump characteristicsEN 12845 and EN 12259-12 require stable QH
characteristics. The total head declines continuously
with increasing flow rate.
Fig. 3
Specific duty requirementsAn orifice plate can be included where the maximum
flow from the pump is critical (for determining the stored
water capacities). The effect of an orifice plate is to
throttle the pump curve and provide a steeper fall-off in
performance. This does, however, result in power
losses through loss of pump efficiency.
Impellers can be trimmed to provide a tailor-made
pump curve. This means that the closed-valve
pressure, power demand and potential maximum flow
rate from the pump are optimised to suit specific duty
requirements.
Performance curves of pumps used in precalculated
systems for hazard class OH1, OH2 and OH3 can be
seen on page 10 to 18. The pump impeller has been
trimmed and an orifice plate used to match the design
data requirements for the specific hazard class.
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. 4 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. 5 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. A supplier test is prepared, and the result
recorded on the test certificate.

Product description Fire NBF, Fire NKF
Power ratingTo ensure that the motor (electric motor or diesel
engine) is capable of operating the pump at any time, to
ensure water supply, EN 12845 and EN 12259-12
stipulate an excess capacity of motor power.
According to EN 12845 and EN 12259-12, the motor
power is found at 16 m NPSH. The example below
show a required motor size of 22 kW.
Fig. 6 Required and stipulated power
ControllerGrundfos offers a complete, factory-assembled
controller in a steel plate cabinet, suitable for wall
mounting or free-standing.
The controller complies with the standard EN 12845.
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.
Functions
The starting signal for the fire pump is given via two
redundant pressure switches. The fire pump can only
be switched off manually.
The control of the fire pump has been arranged in such
a way that motor failures, for example due to heating,
do not cause the fire pump to stop, but only in fault
indications and/or a potential-free signal to a
superordinate fault centre.
Other system components
Jockey pumps
Grundfos 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 operated manually or
automatically by using 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
by means of the respective buttons.
Scope of delivery
A complete Fire NBF and Fire NKF unit assembled and
supplied from factory normally comprises these
elements:
• a pump and motor mounted on a common base
plate/frame
• a standard coupling protected by a coupling guard
(NKF).
Fire NBF and Fire NKF pumps can be ordered with or
without a controller according to EN 12845.
Commissioning
The installer should commission the complete fire set
before handing it over to the plant manager on site.
Many potential issues of the complete fire 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, EN (12845) stipulates that fire
system tests should be carried out, for example:
• 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 fire system
has been installed according to EN (12845)
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.
