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.
