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: 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: 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 installation, 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, lan-tern rings, bottoms of stuffing boxes, interior nuts, lin-ings 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 concerning these features:
• flow vs. pressure• closed-valve pressure• motor 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.
Motor power ratingThe maximum motor current under any condition of pump load must not exceed the rated full-load current multiplied by the service factor. 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 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 and the example below.

ExampleThe maximum power required for this pump is 25 kW.
If the motor service factor is 1.15, the minimum motor size required is 25/1.15 = 21.7 kW. Select the next higher motor size, a 22 kW motor.
If the motor service factor is 1, the minimum motor size required is 25/1 = 25 kW. Select the next higher motor size, a 30 kW motor.
Other system componentsElectric motorsElectrically operated fire systems are equipped with open drip-proof (ODP) motors to the NEMA MG-1 Standard.
The motors are specifically FM-approved and UL-listed for fire applications.
Jockey pumpsGrundfos CR pumps are used as jockey pumps, maintaining the pressure. Under normal conditions, the jockey pump is 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 panelThe 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 FM and CSA.
The control panel is painted with RAL 3000 (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 15.

Stuffing boxThe stuffing box is made of braided packing rings. Braided material ensures a long service life of packing rings and protects the pump shaft (sleeve). The packing rings are installed symmetrically with parallel faces to prevent tilting.
Materials
PTFE-impregnated fibre packing rings and EPDM O-rings in pump housing.
Type of barrier fluid• DNF: internal barrier fluid• HSF: external barrier fluid.
Fig. 16 Sectional view of uncooled stuffing box with internal flushing liquid for DNF pumps
Fig. 17 Sectional view of uncooled stuffing box with external flushing liquid for HSF pumps
CouplingElectrically powered DNF, HSF pumps are fitted with a standard coupling of the close-coupled type with elastic grid.
Fig. 18 Standard coupling
ImpellerThe closed impeller made of bronze has double-curved blades with smooth surfaces for high efficiency.
Fig. 19 Impeller for a DNF pump
Fig. 20 Double-suction impeller for an HSF pump
The impellers are hydraulically balanced and dynamically balanced together with the shaft. The hydraulic balancing compensates for axial thrust.
The direction of rotation of the impeller is clockwise when viewed from the motor.
The impellers are adapted to the duty point required by the customer.

FoundationElectrically powered DNF pumps and motor are mounted on a common steel plate. See fig. 21.
Fig. 21 Schematic view of Fire DNF
Electrically powered HSF pumps and motor are mounted on a common base frame. See fig. 22.
Fig. 22 Schematic view of Fire HSF
Surface treatmentCast iron parts are coated with a protective primer (thickness of 30 μm ±5 μm).
The part is cleaned with an organic solvent and finally spray-painted with red, two-component paint, RAL 3000. The thickness of the dry coating is 30 μm ±5 μm.
Test pressureBefore 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).
MotorThe open, dip-proof motor is specifically UL-listed for fire fighting applications. Main dimensions are accord-ing to the NEMA MG-1 standard.

Fire DNF, Fire HSFOperating conditions
Pump unit locationThe pump unit is designed for installation in a non-aggressive and non-explosive atmosphere.
The relative air humidity must not exceed 95%.
Ambient temperature and altitudeThe 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. 23.
Fig. 23 Relationship between motor output (P2) and ambient temperature/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 pressure) in any operating condition.

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. 24.
Fig. 24 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. 25 Example of piping, Fire DNF
AlignmentIn 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 pump/motor alignment may be affected during transport. Always check the alignment after the pump has been installed.
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.
Note: Check the final alignment when the pump has obtained its operating temperature under normal oper-ating conditions.

Curve charts Fire DNF, Fire HSF
GuideThe tables above the curve charts on the following pages show these data:
• the FM-approved and UL-listed pressure range• the Emerson and WEG range of motors.
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.
Motor rangeExample: DNF 80-20 500 gpm
The motor range for Emerson and WEG is only to be regarded as a guideline. The ranges differ because of differing service factors, SF. See pages 26 to 27.
Curve conditions
Selection of pumpsThe guidelines below apply to the performance curves shown in the curve charts, pages 33 to 49.
• 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 4.

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.
