Fire DNF, Fire HSFNFPA standards
Introduction to the NFPAThe 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 standards and requirements for fire prevention and suppression activities, training, equipment and other life-safety codes and standards.
The NFPA standards are often revised, due to new information and technical equipment.
See the NFPA homepage: http://www.nfpa.org.
NFPA 20The DNF, HSF 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 and private buildings.
The pumps have been tested and certified by FM Global (FM) and Underwriters Laboratories Inc. (UL) to comply with the requirements of the NFPA 20. Compliance with the requirements is indicated by the FM and UL marks affixed to the pumps. See fig. 1.
Fig. 1 FM and UL marks
Other NFPA standardsThese standards are also of relevance to the products described in this data booklet:
• NFPA 13. Installation of sprinkler systems• NFPA 25. Standard for the inspection, testing and
maintenance of water-based fire protection systems• NFPA 70. National Electrical Code.See the NFPA homepage: http://www.nfpa.org.
FM GlobalThe FM Global (FM*) is a mutual commercial and indus-trial property insurance and risk management organisa-tion, located in the USA with offices worldwide.* FM is short for Factory Mutual.
FM tests and approves industrial and commercial prod-ucts in compliance with its own standards, or other nationally recognised requirements.
The FM Approved mark indicates that the product com-plies with the required standards. See fig. 1.
See the FM homepage: www.fmglobal.com.
Underwriters LaboratoriesUnderwriters Laboratories Inc. (UL) is an independent, non-profit, product-safety testing and certification organisation located in the USA.
UL does not "approve" any product. Rather it tests product samples and permits acceptable products to carry the UL mark, as long as they remain in conformity with the standards and with the samples tested to those standards.
UL maintains a list of more than 100,000 products it has tested. The database with the UL-listed products is available online to the public.
The "UL File Number" of a product can be used to look up a certificate at the UL homepage. See www.ul.com > Online Certifications Directory.
Standards approval processGrundfos tests the pumps and fills in the application forms for each individual pump size. We submit this documentation to FM and UL:
• Expected pump performance, including total head, power requirements 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 determinate shaft size, casing bolt size and anti-friction bearing life.
• General assembly drawings, a complete set of man-ufacturing drawings, materials lists and physical property specifications, expected marking format, brochures, sales literature, specification sheets, in-stallation, operating and maintenance procedures.
If the application forms are accepted, FM and UL will attend the final test at the Grundfos premises.
If the evaluation of the test results is positive, FM and UL issue a certificate of compliance of the pump with the standards specified.
If a pump component is replaced after the certificate of compliance has been issued, representative samples of the pump may need to be re-tested.

Overview of fire system
Fig. 2 Overview of fire system
System designA 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.
Systems with only one fire pump or more than two fire pumps are, however, also seen.
OperationThe 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 unnec-essarily. The jockey pump has two pressure levels:
• a low pressure level to start the jockey pump • a high pressure level to stop the jockey pump.In case of further decrease of system pressure due to fire (i.e. sprinkler opens), the duty pump starts. In case this pump fails to start or breaks down, the standby pump will start.
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 installa-tion, each fire unit must comply with NFPA standards.
Fire pumpsFM-approved and UL-listed 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.
MaterialsImpeller, 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 corrosion-resistant material.

NFPA standards Fire DNF, Fire HSF
Performance requirementsFM-approved and UL-listed pumps comply with require-ments of
• flow vs. pressure• closed valve pressure• engine power rating.
Flow vs. pressureThe approval/listing of the pump is based on a certain rated flow, indicated by the solid line in the curve charts. The pump must be able to supply not less than 150% of the rated flow (broken line) and still be able to provide at least 65% of the total rated pressure. See fig. 3 and the example below.
Fig. 3 Flow vs. pressure
ExampleThe pump complies with a flow requirement of 750 gpm (170 m³/h). At this flow, the pump delivers a pressure of 44 psi (31 mH). To be FM-approved/UL-listed, the pump must comply with these requirements:
At 150% of the total rated flow, the pump delivers a pressure of 34 psi (24 mH). This means that the pump complies with the requirements.
Closed-valve pressureThe closed-valve pressure must be at least 101% and not higher than 140% of the total rated pressure. See fig. 4 and the example below.
Fig. 4 Closed-valve pressure
ExampleThe curve shows a rated pressure of 44 psi (31 mH). To be FM-approved/UL-listed, the pump must comply with these requirements:
The pump has a closed-valve pressure of 53 psi (37 mH). This means that the pump complies with the requirements.
Engine power ratingTo ensure that the engine is capable of operating the pump at any time, the NFPA demands that the manu-facturer 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. See fig. 5.

Engine construction Fire DNF, Fire HSF
Engine type and ratingThe compression-ignition diesel engine must be approved/listed for fire pump operation. The mark of the listing laboratory (FM and/or UL) is displayed on the engine nameplate showing compliance with the per-formance ratings and functional requirements.
The engines are rated at standard SAE conditions at 752.1 mmHg barometer and 25°C (77°F) inlet air tem-perature. (SAE = Society of Automotive Engineers.)
Listed engines have an additional 10% power reserve of the pump’s maximum requirement.
Instrumentation and control devicesThe local instrumentation on the engine is shown in fig. 21. The control panel monitoring the fire system is described in a different data booklet.
Fig. 21 Instrumentation on the engine
The engine must have:
• a governor cable for regulating the engine speed within a range of 10% between shut-off and maxi-mum load
• an overspeed shut-down device arranged to shut down the engine at a speed approximately 20% above the rated engine speed.
Starting systemThe engine is provided with two storage battery units. At 4.5°C (40°F) each battery must have twice the capacity sufficient to maintain a 3-minute attempt to start cycle (6 consecutive cycles of 15 seconds crank-ing and 15 seconds rest).
Two systems for recharging the batteries are used:
• An engine-driven generator/alternator recharging the batteries when the diesel engine is running. This system is completely independent of external resources.
• Automatically controlled charger power supplied from the building and fitted in the control panel.
Both chargers must be listed for fire pumps.
Engine coolingThe engine cooling system is of the closed-circuit heat exchanger type.
Cooling water is piped through a threaded, rigid pipe from the pump discharge to the inlet of the heat exchanger. The wastewater can be discharged into a visible, open waste cone or go back to a suction reser-voir.
The heat exchanger has the best efficiency at 60 psi.
Engine exhaustEach engine must have an independent exhaust sys-tem.
A flexible connection is used between the engine and the exhaust pipe to provide thermal expansion and to isolate engine vibration to the rest of the exhaust run. The flex connector should not be used for misalign-ment.
The exhaust system must be building-supported, not engine supported.
Fuel arrangementThe fuel tank outlet must be placed above the engine fuel inlet.
The fuel tank must be sized for 5.1 l/kW (1 gallon/hp) plus 10% (5% for expansion and 5% for sump).

Fire DNF, Fire HSFOperating conditions
Pump unit locationThe pump unit is designed for installation in a non-aggressive and non-explosive atmosphere.
Ambient temperatureThe ambient temperature must not exceed +25°C (77°F).
If the ambient temperature exceeds +25°C (77°F) or if the engine is installed more than 90 metres (300 ft) above sea level, the engine power must be derated according to figures 23 and 24. It may be necessary to use an oversize engine with a higher output.
Fig. 23 Relation between engine output (P2) and ambient temperature
Fig. 24 Relation between engine output (P2) and altitude
Inlet pressureMaximum inlet pressureThe inlet pressure is limited by the maximum operating pressure. The maximum inlet pressure is 100 psi (approx. 7 bar).
Minimum inlet pressureThe pressure at the pump suction flange must be 0 bar (atmospheric pressure) or higher (positive inlet pres-sure) in any operating condition.
Ventilation requirementsThe inlet louvre and ventilation system must
• ensure that the temperature in the room does not exceed 49°C (120°F)
• supply adequate air for engine combustion.Adequate air for ventilating radiated heat; both engine and exhaust system.
Fig. 25 Room ventilation
Minimum temperature of the pump room4.5°C (40°F).
Maximum temperature of the pump room49°C (120°F) at the air cleaner inlet with the engine run-ning at rated load.
Air humidityThe relative air humidity must not exceed 95%.
Engine protectionThe engine must be protected against possible inter-ruption of operation through explosion, fire, flood, earthquake, freezing and other adverse conditions.

Installation
PipingWhen installing the pipes, make sure that the pump housing is not stressed by the pipework.
The suction and discharge pipes must be of an ade-quate size, taking the pump inlet pressure into account.
Install the pipes so that air locks are avoided, especially on the suction side of the pump. See fig. 26.
Fig. 26 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.
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; other-wise, the pump will be damaged.
Fig. 27 Example of piping, Fire DNF.
AlignmentThe engine crankshaft and the pump shaft must be par-allel aligned. We recommend a 3-degree disalignment between the PTO shaft and the engine/pump shaft to ensure even wear of the joints in the PTO shaft.
The pump/engine alignment may be affected during transport. Always check alignment after the pump has been installed.
Take care to align carefully as this will increase the working lives of the coupling, bearings and stuffing boxes.

QH curve for the individual pump
The solid line represents the rated flow at which the pump has been FM-approved and UL-listed.
Pump type and nominal pump speed.
The broken line represents the maximum permissible flow at which the pump has been FM-approved and UL-listed.
The power curve indicates pump input power, P2, for the individual pump.
The eta curve indicates the pump efficiency for the individual pump.
Curve charts Fire DNF, Fire HSF
GuideThe tables above the curve charts on the following pages show:
• the FM-approved and UL-listed pressure range• the Clarke range of engines.
FM-approved and UL-listed pressure rangeExample: DNF 80-20, 500 gpm
The curve charts show curves at 5 psi pressure inter-vals, in this example at 65, 70 and 75 psi. If a duty point at 65 psi is required, the pump will only be FM approved.
Emerson and WEG range of enginesExample: DNF 80-20 500 gpm
The engine type, JU4H-UF14, covers the whole pres-sure range. For more specific information on the engines, see "Engine construction", pages 27 to 30, and "Diesel engine data", pages 25 to 26.
Curve conditions
Selection of pumpsThe guidelines below apply to the performance curves shown in the curve charts, pages 38 to 73.
• Tolerances according to ISO 9906, Annex A.• The curves show pump performance with different
impeller diameters at the nominal speed.• The curves apply to the pumping of water at a tem-
perature of +20°C (68°F) and a kinematic viscosity of 1 mm2/s (1 cSt).
Calculation of total headThe total pump head consists of the height difference between the measuring points + the differential head + the dynamic head.
Performance testsThe requested duty point for every pump is tested according to ISO 9906, Annex A.
If the customer requires either more points on the curve to be checked or certain minimum performances or cer-tificates, individual measurements must be made.
FM/UL certificatesThe pump order includes a test certificate confirming the required QH performance. See page 5.

Sizing
This section is based on different fields of application and installa-tion examples, and gives easy step-by-step instructions in how to• select the most suitable and efficient pump for your installation• carry out advanced calculations based on energy consumption,
payback periods, load profiles, life cycle costs, etc.• analyse your selected pump via the built-in life cycle cost tool• determine the flow velocity in wastewater applications, etc.
Replacement
In this section you find a guide to selecting and comparing replace-ment data of an installed pump in order to replace the pump with a more efficient Grundfos pump. The section contains replacement data of a wide range of pumps produced by other manufacturers than Grundfos.
Based on an easy step-by-step guide, you can compare Grundfos pumps with the one you have installed on your site. When you have specified the installed pump, the guide will suggest a number of Grundfos pumps which can improve both comfort and efficiency.
CAD drawings
In this section it is possible to download 2-dimensional (2D) and 3-dimensional (3D) CAD drawings of most Grundfos pumps.
These formats are available in WebCAPS:
2-dimensional drawings:• .dxf, wireframe drawings• .dwg, wireframe drawings.
3-dimensional drawings:• .dwg, wireframe drawings (without surfaces)• .stp, solid drawings (with surfaces)• .eprt, E-drawings.
