Fire NKFVdS standard

Introduction to VdSVdS Schadenverhütung GmbH is an independent, international, accredited and notified testing and certification institution for fire prevention and safety technology as well as for physical and electronic protection against intrusion. ("Schadenverhütung" is the German word for "loss prevention".)

Accredited according to the EN 45000 series of European standards, VdS Schadenverhütung is a member of the European Fire and Security Group (EFSG). VdS experts are represented in all relevant German and international committees.

The concept behind VdS recognition is to ensure tested and certified quality in the products and services offered in the safety and security markets. This is equally advantageous for user and supplier.

For further information on VdS, see www.vds.de.

VdS standardsThe products in this data booklet have been built to comply with VdS standards on water-based fire fighting systems, described in the following documents:

• VDS CEA 4001:2005-09 (02): Planning and installation.

• VDS 2100: Guidelines for water-based fire fighting systems.

• VDS 2344: Procedures for testing and approval of equipment, components and systems used in fire protection and security control.

Standards approval processGrundfos is to test the pumps and fill in the application forms for each individual pump size. The following documentation should to submitted to the VdS:

• complete drawings with list of parts and materials of the major components

• a statement regarding quality and production (ISO 9001 + Annex A & D)

• a complete data sheet with technical information• complete installation and operating instructions.If the application forms are accepted, VdS will attend the final test at the Grundfos premises. If the evaluation of the test results is positive, VdS will issue a certificate on the approval of the pump.

Overview of fire system

Fig. 1 Overview of fire system

Fire 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.

FunctionThe duty and standby pumps are not powered by the same source. Either both pumps are electrically powered, supplied by two separate sources, or one pump is electrically powered and the other diesel-powered. This ensures that if one pump fails, for example due to fire damage, the other will operate.

The pumps are pressure-controlled by pressure sensors.

The pressure in the system is normally maintained by the pressure tank.

If the system pressure drops, the water level and air pressure in the tank will decrease.

The jockey pump starts to fill the tank, and the compressor to boost the pressure. If the jockey pump and the compressor succeed in boosting the water level and the pressure to a set value, both will stop. If a sprinkler has been activated and the water level and the pressure keeps falling, the duty pump will start.

A further decrease in the pressure means that the duty pump is not running, and the standby pump will start.

The same principle applies to the dry sprinkler system in which an air compressor maintains pressure from the alarm valve and through the sprinkler system.

Although individually designed for the specific installation, each fire system must comply with VdS standards.

Important!Requirements as to design, sizing and testing of fire protection systems vary from one country to another.

Fire pumpsGrundfos end-suction pumps approved by VdS are designed for the distribution of water in stationary sprinkler systems using either foam or water spray. They are operated in case of fire and during tests.

MaterialsRequirements of materials for VdS-approved pumps:

• impeller and wear rings made of bronze• wet parts such as shaft, washers and nuts made of

stainless steel• castings made of EN-GJL-250.VdS requirements for EN-GJL-250 do not allow heads (H) above 110 metres and flows (Q) above 600 m3/h.

Pump characteristicVdS focuses strongly on the instabilities, due to sprinkler systems consisting of long and different pipe circuits. Two instable pumps may cause vibrations or breakdown.

If the pump characteristic is instable, it is not allowed to exceed 5 %. See examples of instable (fig. 2) and stable (fig. 3) pump characteristics below.

Fig. 2 Instable pump characteristics

Fig. 3 Stable pump characteristics

Duty rangeVdS operates with a concept known as Qzul (zulässig = permissible), see fig 4. The duty point of the pump must not be to the right of this limit.

Qzul is defined on the basis of the pump NPSH curves. The following calculation must be made for the largest and smallest pump impeller diameter.

ExampleThe following example shows how Qzul has been shown for the pump characteristics in fig. 4.

Qzul for ∅219 impeller:

The maximum permissible flow of an NKF 50-200 pump with ∅219 impeller is 99 m3/h.

Qzul for ∅170 impeller:

The maximum permissible flow of an NKF 50-200 pump with ∅170 impeller is 78 m3/h.

On the basis of Qzul ∅219 and Qzul ∅170, the limit Qzul can be drawn and the duty range of the impellers in between can be read.

Motor power ratingTo ensure that the motor is capable of operating the pump at any time, so that it can deliver water, VdS requires an excess capacity of motor power.

According to VdS, the motor power is found at 16 m NPSH. The example below is based on Qzul = 99 m3/h as previously calculated.

Fig. 5 Necessary and required power

SpecificationsEach curve chart is followed by a specification of technical data. See table below.

VdS Approval NoEach pump has its own VdS approval number.

D2 normal

D2 indicates the largest impeller diameter of the specific pump.

D2 turned downD2 turned down indicates the reduced diameters of the impellers, approved for each model.

b2The impeller is of the closed type. The b2 dimension indicates the width of the opening where water leaves the impeller.

Fig. 6 b2 impeller dimension

When the impeller diameter is reduced, the b2 dimension is increased.

Q4.5 m NPSH = 110 m3/h

Q5.5 m NPSH = 119 m3/h

Q4.5 m NPSH x 1.2

110 x 1.2 = 132

Does the result exceed the value of Q5.5 m NPSH?

132 > 119

Yes Qzul = Q5.5 m NPSH / 1.2

Qzul ø219 = 119 / 1.2 = 99 m3/h

Q4.5 m NPSH = 93 m3/h

Q5.5 m NPSH = 93 m3/h

Q4.5 m NPSH x 1.2

93 x 1.2 = 112

Does the result exceed the value of Q5,5 m NPSH?

112 > 93

Yes Qzul = Q5.5 m NPSH / 1.2

Qzul ∅170 = 93 / 1.2 = 78 m3/h

Electrical motorsGrundfos electrical fire systems are equipped with MMG-E motors (sourced HEM EFF2 motors) produced according to IEC 60034.

Insulation class: F.Enclosure class: IP55.

Jockey pumpsGrundfos 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 highlevel 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.

There are no specific VdS requirements as regards the jockey pump.

ControllerThe controller for the electrical fire pump complies with the CEA 4001 standard.

The Grundfos electrical fire system is equipped with VDS-approved controller, sourced externally. The controller has these features:

• optional phase monitoring • colour red (RAL 3000)• compliance with IP 54.The controller can be mounted on the wall or fitted with stands to the base frame of the electrical fire fighting unit.

CommissioningThe installer should commission the complete fire unit 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, VdS 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 VdS 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.

Mechanical constructionPump housingThe cast iron volute pump housing has axial suction port and radial discharge port. Flange dimensions are according to EN 1092-2.

The pump housings have both a priming and a drain hole closed by plugs.

Fig. 11 NKF pump housing

Bearing bracket and shaftThe bearing bracket has two sturdy, antifriction, lubricated-for-life bearings. However, oversize pumps with 55 mm shaft diameter have open bearings with lubricating nipples.

The bearing bracket is made of cast iron, EN-GJL-250.

The shaft is made of stainless steel, DIN W.-Nr. 1.4021/AISI 420. Shaft diameter d5 is either ∅24, 32 or 55.

A thrower on the shaft prevents water from entering the bearing bracket.

Fig. 12 Bearing bracket and shaft

All NKF pumps are fitted with one of four shaft, shaft seal and bearing sizes.

Shaft sealThe shaft seal is an unbalanced, mechanical shaft seal with dimensions to EN 12 756. Seal faces are available in a variety of combinations. The code of the standard version is BAQE, see page 16.

The drawings below illustrate shaft seals for NKF, model A.

Fig. 13 Rubber bellows seal type BAQE counteracts deposits from the pumped water

CouplingNKF pumps are available with two types of coupling:

• standard • spacer.

Fig. 14 Standard coupling

Fig. 15 Spacer coupling

Pumps fitted with a spacer coupling can be serviced without dismantling the motor from the base frame and without removing the pump housing from the pipework. This saves realignment of pump and motor after service.

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

Fig. 16 Impeller for an NKF pump

All impellers are dynamically and hydraulically balanced. The hydraulical balancing compensates for axial thrust.

The direction of rotation of the impeller is clockwise when viewed from the motor.

All impellers are adapted to the duty point required by the customer.

Base framePump and motor are mounted on a common, steel base frame.

Fire NKFOperating conditions

Pump unit locationThe pump 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.

If the ambient temperature exceeds +40 °C or if the motor is installed more than 1000 metres above sea level, the rated motor output will fall due to the low density and consequently low cooling effect of the air. In such cases, it may be necessary to use an oversize motor with a higher output. See fig. 18.

Fig. 18 The motor P2 depends on temperature/altitude

Duty range of shaft sealThe NKF pump is equipped with a BAQE shaft seal, i.e. a rubber bellows seal with metal-impregnated carbon/silicon carbide seal faces and EPDM rubber parts.

Temperature range: 0 °C to +120 °C.

Inlet pressure

Maximum inlet pressureThe inlet pressure is limited by the maximum operating pressure. The maximum inlet pressure appears from this table:

Minimum inlet pressureThe minimum inlet pressure must be according to the NPSH curve + a safety margin of at least 1 metre + correction for vapour pressure, according to VdS CEA 4001 : 2005-09 (02).

See fig. 19.

Installation and operation

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 adequate 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. 20.

Fig. 20 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 the discharge side. The counter flanges should lie true against the pump flanges without being stressed; otherwise, the pump will be damaged.

Fig. 21 Example of piping, Fire NKF

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 alignment after the pump has been installed.

If misalignment has occurred due to radial or angular shifting, realign by inserting/removing shims under the feet of the pump or the motor.

Take care to align carefully as this will increase the working lives of the coupling, bearings and shaft seals considerably.

Note: Check the final alignment when the pump has obtained its operating temperature under normal operating conditions.

Curve conditions

Selection of pumpsThe guidelines below apply to the curves shown in the performance charts, pages 29 to 35.

• Tolerances according to ISO 9906, Annex A and VdS 2100.

• The curves show pump performance with different impeller diameters at the nominal speed.

• The bold part of the curves shows the recommended operating range.

• The thin parts are not allowed according to VdS.• Do not use the pumps at minimum flows below

0.1 x Q at optimum efficiency because of the danger of overheating of the pump.

• The curves apply to the pumping of water at a temperature of +20 °C and a kinematic viscosity of 1 mm2/s (1 cSt).

• NPSH: The curves are according to the minimum and maximum impeller diameter.

• In case of other densities than 1000 kg/m3 the discharge pressure is proportional to the density.

• When pumping water with a density higher than 1000 kg/m3, motors with correspondingly higher outputs must be used.

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, and VdS 2100.

If the customer requires a specific impeller diameter (not a specific duty point), the pump will be tested at a duty point which is 2/3 of the maximum flow of the published performance curve related to the ordered impeller diameter (according to ISO 9906, Annex A).

If the customer requires either more points on the curve to be checked or certain minimum performances or certificates, individual measurements must be made.

VdS certificateThe pump order includes a test certificate confirming the required QH performance.

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.

Fire NKFController

General descriptionThe Grundfos CONTROL FS 1 fire system controller is a complete, factory-assembled controller in a steel plate cabinet, suitable for wall mounting or free-standing.

The controller has been designed without main switches to comply with the regulations of the VdS (Loss Prevention Authority).

If a fire pump can be powered by more than one electricity supply network, a controller with a load transfer breaker must be installed.

Functional descriptionThe 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.

In addition to the fire pump, ancillary VdS-approved equipment can also be controlled.

Controller versionsThe controller is available in two versions:

• With monitoring module (WM)• Without monitoring module (WO/M).

Controller with monitoring moduleMonitoring modules for power system monitoring as well as for pressure switch wire-breakage and/or short-circuit monitoring are integrated into the WM version of the controller.

It is essential that a corresponding resistance module, WM1, is attached to each pressure switch for this purpose.

Controller without monitoring moduleWithout the monitoring modules integrated in this version, no potential-free signals are given in case of phase or pressure-switch failure.

IdentificationType key, standard operating devices

The example above is a controller for a fire fighting pump in the range of 133 to 160 kW. The controller has monitoring modules for phase-failure, cable breakage and short circuit.

Type key, optional operating devices

NameplateThe nameplate made of sheet metal is riveted to the front door of the control cabinet. The nameplate is positioned at the bottom right of the door.

Controller Fire NKF

ConstructionThe control cabinet made of steel sheet is ingress-protected to IP 54. The standard colour of the cabinet is red (RAL 3000). The mounting plate is made of 3 mm galvanised sheet steel.

The cabinet design depends on the selected options and the performance of the fire pump. The dimensions of the control cabinet depend on the number of options installed and on whether the controller is for wall-mounting or free-standing. See also “Cabinet dimensions”, page 53.

Cables of wall-mounted controllers enter through cable glands.

Cables of free-standing controllers enter a 100 mm high base frame and a bottom plate split in three parts.

Control panelThe control panel design depends on the selected options. The control panel has a number of standard components (applies to all models) and optional components (selected options). See fig. 24 and the tables below.

Potential-free signalling contactIf a component in the controller detects a change, a potential-free signalling contact will generate a fault indication or indicate a new operating condition. These indications can be seen on the control panel and/or in a superordinate fault centre.

CablesStar-delta startingEither one three-core and one four-core cable or two four-core cables, such as NYY and similar types.

Direct-on-line or autotransformer staringOne four-core cable.

Optional equipmentDepending on the option selected, two fused supply cables are available for the connection of auxiliary units.

Controller componentsOvervoltage protection device (option)The overload protection device for the mains configuration TN-S (L1, L2, L3, N, PE) diverts dangerous overvoltages to the protective-earth conductor.

When the protection device has been activated, the red indicator light is on.

Fig. 25 Overvoltage protection device

The device consists of four individual modules. For TN-S systems, these modules are individually interchangeable.

Each module has a potential-free changeover contact which can trigger the relay for fault indication.

Phase-failure relay (only for WM version)The phase-failure relay monitors the three-phase power systems with neutral conductors. The operator can adapt the phase-failure relay to the conditions of the supply network.

Note: The device is designed for a rated voltage of 250 V AC and a frequency of 48 to 63 Hz.

Functions• adjustable threshold values• adjustable response delay• phase sequence and phase-failure monitoring• asymmetry monitoring with adjustable scale for

divergence.

Operating modes• UNDER (U): Undervoltage monitoring• UNDER+SEQ (U+S): Undervoltage and phase-

sequence monitoring• WIN (W): Monitoring of the range between the min.

and max. thresholds• WIN+SEQ (W+S): Monitoring of the range between

the min. and max. thresholds and phase-sequence monitoring.

Fig. 27 Monitoring module for pressure switches

Slide switchesThe monitoring module has three slide switches at the front for the control of the function of the monitoring module. The contact behaviour of the output relay, the wire breakage detection and the short-circuit monitoring can be set.

PositionThe three slide switches must be in the correct position:

NC: Quiescent current behaviour of the output relay, closes when a contact is opened on the input side

WB: Wire breakage monitoring

SC: Short-circuit monitoring.

LEDsTwo LEDs are located above the slide switches:

• Pwr:Green = applied voltage.

• 1:Yellow = low system pressure.Red = wire breakage or short-circuit.

Resistance module, WM1A resistance module must be directly connected to the respective pressure switch.

Operating conditionsTemperature rangeAmbient temperature: 0 to 40 °C

Storage and transport: –25 to 60 °C.

Relative humidityKeep air humidity at a low level to prevent the formation of moisture.

Installation

General informationThe installation and connection of the controller must comply with local regulations and accepted codes of good practice. This includes, among others, DIN VDE 0100, DIN VDE 0660, DIN VDE 0106 as well as the accident prevention regulations of the Accident Prevention and Insurance Association UVV VBG 4.

Take into account the regulations for VdS-approved systems, especially VdS 2092 and VdS 2100.

Also observe the regulations of the local power supply companies.

Electrical connectionThe controller is approved for connection to the conventional TN system.

Disconnection by means of an overcurrent device (DIN VDE 0100/part 410) can be used as a protective measure from indirect contact.

Note: Residual current circuit-breakers are not allowed for the supply to VdS systems for special protection reasons.

Different and/or supplementary preventive measures may be required for special network configurations, for example IT or TT systems, which may possibly cause alterations to the controller. The sizing of the supply cable must allow for the overload and short-circuit protection in compliance with DIN VDE 0100, part 430.

The safeguard in the low-voltage main distribution system and in the emergency power system is to be conducted taking the selectivity of the NH-fuse in the fire pump controller into account.

The cables for VdS systems should be selected and laid in such a way that they remain functional in the event of a fire (fire protection covering E 30 or E 90 or cables with function preservation E 90).

The voltage supply to the X0 supply terminals takes place via an applied clockwise rotating field.

The line-to-line voltages can be read from the voltmeter by means of the input selector switch.

Motor connection The cables from the controller to the fire pump motor should be sized in accordance with DIN VDE 0100, part 430, to ensure short-circuit protection and to comply with the permissible line-drop voltage. The existing overload relay in the load circuit of the motor does not result in disconnection (VdS requirement) when it is triggered, but only in an indication of the fault.

The factory setting of the motor outlet for the fire pump motor has been set to "counter-clockwise rotation".

OperationThis section covers the following:

• fire pump• jockey pump (optional)• compressor (optional)• pressure-maintaining pump (optional)• level indication (optional)• motor valve (optional).If the system is in automatic mode during pump start-up, the jockey pump and compressor operate as normal. All additional units are disconnected.

Fire pumpDuring a decrease of pressure in the fire system, the fire pump is switched on automatically via the external pressure switches.

The fire pump can be manually switched on and off by means of the respective buttons.

Jockey pumpThe jockey pump can be operated manually or automatically by using the selector switch.

During automatic operation, the jockey pump is conducted by an external float switch in the pressure tank.

If operation of the compressor is required (due to a decrease of pressure in the pressure tank) and the water level is below the normal level, the jockey pump starts automatically until the normal water level is reached. Subsequently, the nominal pressure is restored using compressed air.

The jockey pump can be manually switched on and off by means of the respective buttons.

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.

Pressure-maintaining pumpThe pressure-maintaining pump can be operated manually or automatically by using the selector switch.

During automatic operation, the pressure-maintaining pump is controlled by an external pressure switch.

The pressure-maintaining pump can be manually switched on and off by means of the respective buttons.

Level indicationRod electrodeA 4-pin rod electrode can be used in combination with the appropriate electrode relay for monitoring the level in the pressure tank. The necessary hysteresis between the individual switching points can occur via the individual truncation of electrode pins.

Float switchA float switch can be used to easily monitor the level in the pressure water tank, surge tank, storage tank, etc. in which a hysteresis of 120 mm is sufficient.

Motor valveThe motor valve can be manually closed and opened by means of the respective push buttons.
