1. Introduction to VdS

VdS 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").

VdS Schadenverhütung is accredited according to the EN 45000 series of European standards and 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 that only tested and certified products and services are offered to 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 firefighting systems, described in the following documents:

• VdS CEA 4001-S:2003-11: Planning and installation.

• VdS 2100-07: Guidelines for water-based firefighting 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)

• data sheet with technical information

• 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, the VdS will issue a certificate on the approval of the pump.

Fire CRFF 1

Fire pumpsGrundfos centrifugal pumps approved by the 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.

Materials

VdS-approved pumps must comply with these requirements:

• impeller, wear rings and wet parts such as shaft, washers and nuts must be made of non-corrosive iron.

• castings must be made of EN-GJL-250 cast iron.

VdS requirements for EN-GJL-250 do not allow heads (H) above 110 m and flow rates (Q) above 600 m3/h. Above 110 m ductile iron is required.

Pump characteristic

The VdS focuses strongly on the instabilities which may be present in sprinkler systems consisting of long and different pipe circuits. Two instable pumps may cause vibrations or breakdown.

If the characteristic is instable, the instability must not exceed 5 %. See examples of instable (fig. 1) and stable (fig. 2) characteristics below.

Fig. 1 Instable characteristics

Fig. 2 Stable characteristics

Duty rangeThe VdS operates with a concept known as Qzul ("zul" is an abbreviation of "zulässig" which means permissible). See fig. 3. 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.

Motor power ratingTo ensure that the motor is capable of operating the pump at any time to supply water, the VdS stipulates an excess capacity of motor power.

Overloading power curves

Motor power is found at 16 m NPSH.

Non-overloading power curves

Motor power is found at the power peak +5 %.

Test pressurePressure testing has been made with +20 °C water containing corrosion inhibitor.

Installation

Pipe connectionWhen 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. 4.

Fig. 4 Pipelines

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.

How to read the curve charts

Curve conditions

Selection of pumps

The guidelines below apply to the curves shown in the performance charts, pages 25 to 31.

• Tolerances according to ISO 9906 and VdS 2100-07.

• The curves show pump performance with different number of impellers at the nominal speed.

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

• The thin parts are not allowed according to the VdS.

• Do not use the pumps at minimum flow rates below 0.1 x Q at optimum efficiency because of the danger of overheating of the pump.

• The curves apply to 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 number of impellers.

• 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 head

The total pump head consists of the height difference between the measuring points + the differential head + the dynamic head.

The power curve indicates pump input power, P2.

The NPSH curve is according to the minimum and maximum impeller diameter.

Qzul indicates the limit of the individual pump performance range according to the VdS.

QH curve for the individual pump

Performance testsThe requested duty point for every pump is tested according to ISO 9906 and VdS 2100-07.

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

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

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

density and viscosity of the pumped liquid and show the number of pumps in operation

• product photos• dimensional drawings• wiring diagrams• quotation texts, etc.

Literature

This section contains all the latest documents of a given pump, such as• data booklets• installation and operating instructions• service documentation, such as Service kit catalogue and

WinCAPS is available on DVD and updated once a year.

Sizing

This section is based on different fields of application and installation examples and gives easy step-by-step instructions in how to size a product:• 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 replacement 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.
