Fire DNF, Fire HSEF
Introduction to the NFPA
Standards approval process
The National Fire Protection Association (NFPA) is an
international, non-profit organisation of fire safety
professionals. The NFPA headquarters is located in the
USA.
The organisation creates and maintains minimum
acceptable standards and requirements for fire
prevention and suppression activities, training,
equipment and other life-safety codes and standards.
NFPA standards are typically revised every three years
in order to keep guidelines updated and to prevent the
loss of life and property due to fire.
See the NFPA homepage: www.nfpa.org.
NFPA 20
DNF and HSEF bare shaft pumps comply with the
NFPA 20 Standard for the Installation of Stationary Fire
Pumps for Fire Protection. The standard covers
systems for commercial, industrial and private
buildings.
APPROVED
• Expected pump performance, including total head,
power requirement and efficiency versus flow
characteristics.
If different impeller diameters are used to obtain the
rated head for the pump to be examined, complete
details must be provided concerning performance
specifications to be evaluated.
• Calculations to determine shaft size, casing bolt
size and anti-friction bearing life.
• General assembly drawings, a complete set of
manufacturing drawings, materials lists and physical
property specifications, expected marking format,
brochures, sales literature, specification sheets,
installation, operating and maintenance procedures.
When the application forms have been accepted, the
FM will attend the final test at the Grundfos premises.
When the evaluation of the test results is positive, the
FM will issue a certificate of compliance of the pump
with the standards specified.
When a pump component is replaced after the
certificate of compliance has been issued,
representative samples of the pump may need to be retested.
TM04 4901 2209

System design
A fire system typically consists of three pumps: one
pressure pump (jockey pump) and two fire pumps, one
duty and the other acting as standby. Each of the fire
pumps is capable of achieving the required
performance.
Performance requirements
Systems with only one fire pump with a redundant
power supply or more than two fire pumps are,
however, also seen.
• motor power rating.
Operation
The jockey pump maintains pressure in the system and
compensates for any loss of pressure caused by leaks
and thus prevents the duty pump from starting
unnecessarily. The jockey pump has two pressure
levels:
FM-approved pumps comply with requirements
concerning these features:
• flow rate vs. pressure
• closed-valve pressure
Flow rate vs. pressure
The approval/listing of the pump is based on a certain
rated flow rate, indicated by the solid line in the curve
charts. The pump must be able to supply not less than
150 % of the rated flow rate (broken line) and still be
able to provide at least 65 % of the total rated pressure
when operating at a suction lift of at least 4.6 m (15 ft)
referred to water surface.
See fig. 3 and the example below.
• a low pressure level to start the jockey pump
• a high pressure level to stop the jockey pump.
The duty and standby pumps are not powered by the
same source. This ensures that if one pump fails, for
example due to fire damage, the other will operate. The
pumps are controlled by pressure sensors.
Although individually designed for the specific
installation, each fire unit must comply with NFPA
standards.
Fire pumps
FM-approved Grundfos end-suction and split-case
pumps are designed for the distribution of water in
automatic sprinkler and standpipe systems. They are
operated in case of fire and during tests.
Materials
Impeller, wear rings, guide or diffusion vane rings,
lantern rings, bottoms of stuffing boxes, interior nuts,
linings of stuffing-box throats, glands, gland nuts and
drain plugs are made of material approved by the FM
and UL.

In case of further decrease of system pressure due to
fire (i.e. sprinkler opens), the duty pump will start. In
case this pump fails to start or breaks down, the
standby pump will start.

[psi]
Fig. 3 Flow rate vs. pressure
Example
The pump complies with a flow requirement of 750 gpm
(170 m3/h). At this flow rate, the pump delivers a
pressure of 44 psi (31 mH). To be FM-approved or ULlisted, the pump must comply with these requirements:
Rated flow rate (100 %):
750 gpm (170 m3/h)
Maximum flow rate supplied by the pump
(150 %):
1125 gpm (256 m 3/h)
Rated pressure (100 %):
44 psi (31 metres head)
Minimum pressure supplied by the pump
(65 %):
34 psi (24 metres head)
At 150 % of the total rated flow rate, the pump delivers
a pressure of 34 psi (24 metres head). This means that
the pump complies with the requirements.

44 psi (31 metres head)
Minimum closed-valve pressure (101 %):
44 psi (31 metres head)
Maximum closed-valve pressure (140 %):
61 psi (43 metres head)
The pump has a closed-valve pressure of 53 psi
(37 metres head). This means that the pump complies
with the requirements.
Motor power rating
The maximum motor current under any condition of
pump load must not exceed the rated full-load current
multiplied by the service factor, if any. Service factors
must be in accordance with NEMA Standard MG-1.
To ensure that the motor is capable of operating the
pump at any time, the NFPA demands that the
manufacturer determines the maximum power required
at a certain duty range. The maximum power occurs
when there is no increase in power with an increase in
the flow rate. See fig. 5 and the example below.

Jockey pumps
Grundfos CR pumps are used as jockey pumps,
maintaining the pressure. Under normal conditions, the
jockey pump will be activated by the low-pressure
switch as a result of small leakages, or if one or more
sprinklers are activated.
The jockey pump is not subject to any specific NFPA
requirements.
Control panel
The control panel has the CE-mark.
The control panel for the fire pumps must comply with
NFPA 20 requirements. In addition, the cabinet must be
listed by UL and ULC and approved by the FM and
CSA.
The control panel is painted with RAL 3002 (red) and
housed in a NEMA type-2 drip-proof enclosure.
The control panel is suitable for wall mounting or floor
mounting. See Type keys, page 13.

The cast iron, volute pump housing has axial suction
port and radial discharge port. Flange dimensions are
according to DIN 2533.
The shaft is made of steel, SAE1045.
A rubber deflector on the shaft prevents water from
entering the bearing bracket.
TM03 4599 2306

The cast iron, volute pump casing has radial suction
and discharge port. Flange dimensions are according
to ANSI B16.1.
The pump casing has a priming hole and a drain hole
closed by plugs.

HSEF
The bearing bracket has two sturdy, anti-friction,
grease-lubricated bearings.
The bearing bracket supports are cast integral with the
lower casing half for permanent alignment of bearings
and all rotating parts. The material is minimum class-35
cast iron.

Stuffing box
Coupling
The stuffing box is sealed with braided packing rings.
The braided material ensures a long service life of
packing rings and protects the pump shaft (sleeve). The
packing rings are fitted symmetrically with parallel
faces to prevent tilting. The packing ring joints are
alternately staggered to aid sealing. Removal of the
upper casing allows for ease of inspection and service
of the stuffing box.
Electrically powered DNF and HSEF pumps are
available with two types of coupling:
• standard
• spacer (Fire DNF only).

TM03 4597 2306
• HSEF: external barrier fluid (fig. 17).
Fig. 19 Spacer coupling
DNF pumps fitted with a spacer coupling can be
serviced without removing the motor from the base
plate and without removing the pump housing from the
pipework. This saves realignment of pump and motor
after service.
The split-case construction of HSEF pump enables
removal and dismantling of the internal pump parts, e.g.
bearings, wear rings, impeller and packing rings,
without disturbing the motor or pipework.

The closed impeller made of bronze has double-curved
blades with smooth surfaces for high efficiency.

Fig. 21 Double-suction impeller for an HSEF pump
The impellers are hydraulically balanced and
dynamically balanced together with the shaft.
See fig. 21. The hydraulic balancing compensates for
axial thrust.
The direction of rotation of the impeller is clockwise
when viewed from the motor.
Note: HSEF pumps with counter-clockwise rotation are
available on request.
The impellers are adapted to the duty point required by
the customer by trimming the impeller.
Foundation
Electrically powered Fire DNF pumps and motors are
mounted on a common base plate. See fig. 22.
Before delivery, the pumps are hydrostatically tested
for 5 minutes to 1.5 times the sum of the closed-valve
pressure plus the maximum permissible suction head,
1.5 x (Pmax + Pmax suction), but not less than 250 psi.
Test liquid: Water at 20 °C (68 °F).

Operating conditions
Fire DNF, Fire HSEF
Location
The pump set is designed for installation in a nonaggressive and non-explosive atmosphere.
The relative air humidity must not exceed 95 %.
Ambient temperature and altitude
The ambient temperature must not exceed +40 °C
(104 °F).
If the ambient temperature exceeds +40 °C (104 °F), or
if the motor is installed more than 1000 metres (3280 ft)
above sea level, the motor must not be fully loaded due
to the low density and consequently low cooling effect
of the air. In such cases, it may be necessary to use a
motor with a higher output. See fig. 24.

Installation
Fire DNF, Fire HSEF
Piping
Alignment
Make sure that the pump housing is not stressed by the
pipework. Comply with the pump's maximum forces and
moments allowed.
In a complete pump unit assembled and supplied from
factory, the coupling halves have been accurately
aligned. Alignment is made by inserting shims under
the pump and motor mounting surfaces, as required.
The suction and discharge pipes must be of an
adequate size, taking the pump inlet pressure into
account.
The pump/motor alignment may be affected during
transport. Always check the alignment after the pump
has been installed.
Refer to the rules and regulations of NFPA 20.
Install the pipes so that air locks are avoided, especially
on the suction side of the pump. See fig. 25.
If misalignment has occurred due to radial or angular
shifting, realign by inserting/removing shims under the
supporting feet of the pump or the motor.
Take care to align carefully as this will increase the
working life of the coupling, bearings and stuffing
boxes.
TM00 2263 3393
Note: Check the final alignment when the pump has
obtained its operating temperature under normal
operating conditions.
Fig. 25 Pipe sections
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.
TM03 2998 4006
Make sure the pipes are adequately supported as close
to the pump as possible, both on the suction and on the
discharge side. The counter-flanges should lie true
against the pump flanges without being stressed;
otherwise, the pump will be damaged.

Curve conditions
Selection of pumps
The guidelines below apply to the performance curves
shown in the curve charts, pages 30 to 60.
• Tolerances according to ISO 9906, Annex A.
• The curves show pump performance with different
impeller diameters at the rated speed.
• The curves apply to the pumping of water at a temperature of + 20 °C (68 °F) and a kinematic viscosity
of 1 mm²/s (1 cSt).
Calculation of total head
The total pump head consists of the height difference
between the measuring points + the differential head +
the dynamic head.
H
total
= H
geo
+H
stat
+H
dyn
Hgeo: Height difference between measuring points.
Hstat: Differential head between the suction and the
discharge side of the pump.
Hdyn: Calculated values based on the velocity of the
pumped water on the suction and the discharge
side of the pump.
Note: Selection of the pump is based on the head given
by the customer.
Performance tests
The requested duty point of every pump is tested
according to ISO 9906, Annex A. The curve of the
performance test is supplied with the pump.
If the customer requires either more points on the curve
to be checked or certain minimum performances or
certificates, individual measurements must be made.
