    Control and monitoring of the pump performance.IntroductionThis data booklet deals with CR, CRI and CRN as well asCRE, CRIE and CRNE pumps.

    Fig. 1 CR, CRI and CRN pumps

    CR, CRI, CRN pumps are vertical multistage centrifugalpumps. The in-line design enables the pump to beinstalled in a horizontal one-pipe system where thesuction and discharge ports are in the same horizontalplane and have the same pipe dimensions. This designprovides a more compact pump design and pipework.

    Grundfos CR pumps come with various pump sizes andvarious numbers of stages to provide the flow and thepressure required.

    CR pumps are suitable for a variety of applications frompumping of potable water to pumping of chemicals. Thepumps are therefore used in a wide variety of pumpingsystems where the performance and material of thepump meet specific demands.

    The CR pumps consist of two main components: themotor and the pump unit. The motor on a CR pump is aheavy-duty Grundfos specified motor.

    The pump unit consists of optimized hydraulics, varioustypes of connections, an outer sleeve, a top and variousother parts.

    CR pumps are available in various material versionsaccording to the pumped liquid.

    CRE, CRIE, CRNE pumps

    Fig. 2 CRE, CRIE and CRNE pumps

    CRE, CRIE, CRNE pumps are built on the basis of CR, CRI,CRN pumps.

    CRE, CRIE, CRNE pumps belong to the so-called E-pumpfamily. CRE, CRIE, CRNE pumps are referred to as E-pumps

    The difference between the CR and the CRE pump rangeis the motor. CRE, CRIE, CRNE pumps are fitted with an E-motor, i.e. a motor with built-in frequency control.

    The motor of the CRE pump is a Grundfos MLE motor.

    Frequency control enables continuously variable controlof motor speed, which makes it possible to set the pumpto operation at any duty point. The aim of continuouslyvariable control of the motor speed is to adjust theperformance to a given requirement.

    CRE, CRIE and CRNE pumps are available with an inte-grated pressure sensor connected to the frequencycontrol.

    The pump materials are the same as those of the CR, CRI,CRN pump range.

    Selection a CRE pump

    Select a CRE pump if:

    controlled operation is required, i.e. consumption fluctuates;

    constant pressure is required,

    communication with the pump is required.

    Adaptation of performance through frequency-controlled speed control offers obvious advantages:

    Energy savings.

    Increased comfort.

    Product data for E-pumps Vertical multistage centrifugal pumps

    and vice versa. glass buildings, irrespective of the seasonal fluctuationsof the out-door temperature, and various heat impactsinside the building.Examples of E-pump applicationsCRE, CRIE and CRNE pumps are the ideal solution in anumber of applications characterized by a need for vari-able flow at constant pressure. The pumps are suited forwater supply systems and pressure boosting, but alsoindustrial applications.

    Depending on the nature of the application, the pumpsoffer energy-savings, increased comfort or improvedprocessing.

    E-pumps in the service of industry

    Industry uses a large number of pumps in many differentapplications. Demands on pumps in terms of pumpperformance and mode of operation make speed controla must in many applications.

    Below are mentioned some of the applications in whichE-pumps are often used.

    Constant pressure

    Water supply,

    Washing and cleaning systems,

    Distribution from waterworks,

    Humidifying systems,

    Water treatment systems,

    Process boosting systems, etc.

    Example: Within industrial water supply, E-pumps withintegrated pressure sensor are used to ensure a constantpressure in the piping network. From the sensor, the E-pump receives inputs about changes of pressure as aresult of changes in the consumption. The E-pumpresponds to the input by adjusting the flow until thepressure is equalized. The constant pressure is stabilizedonce more on the basis of a preset setpoint.

    Constant temperature

    Air-conditioning systems at industrial plants,

    Industrial cooling systems,

    Industrial freezing systems,

    Casting and moulding tools, etc.

    Example: In industrial freezing systems, E-pumps withtemperature sensor increase comfort and lower oper-ating costs compared with pumps without a tempera-ture sensor.

    An E-pump continuously adapts its performance to thechanging demands reflected in the differences intemperature of the liquid circulating in the freezingsystem. Thus, the lower the demand for cooling, thesmaller the quantity of liquid circulated in the system

    Constant flow

    Steam boiler systems,

    Condensate systems,

    Sprinkler irrigation systems,

    Chemical industry, etc.

    Example: In a steam boiler, it is important to be able tomonitor and control pump operation to maintain aconstant level of water in the boiler.

    By using an E-pump with level sensor mounted in theboiler, it is possible to maintain a constant water level.A constant water level ensures optimum and cost-effi-cient operation as a result of a stabile steam production.

    Dosing

    Chemical industry (i.e. control of pH-values),

    Petrochemical industry,

    Paint industry

    Degreasing systems,

    Bleaching systems, etc.

    Example: In the petrochemical industry, E-pumps withpressure sensor are used as dosing pumps. The E-pumpshelps to ensure that the correct mixture ratio is achievedwhen more liquids are combined.

    E-pumps functioning as dosing pumps improveprocessing and offer energy-savings.

    E-pumps in commercial building services

    Commercial building services use E-pumps to maintain aconstant pressure or a constant temperature based on avariable flow.

    E-pumps are used in applications such as

    Constant pressure

    Water supply in high-rise buildings i.e. office build-ings, hotels, etc.

    Example: E-pumps with pressure sensor are used forwater supply in high-rise buildings to ensure a constantpressure even at the highest draw-off point. As theconsumption pattern and by that the pressure changesduring the day, the E-pump continuously adapts itsperformance until the pressure is equalized.

    Constant temperature

    Air-conditioning systems in hotels, schools,

    Building cooling systems, etc.

    Example: E-pumps are an excellent solution in buildingswhere constant temperature is essential. E-pumps keepthe temperature constant in air-conditioned high-rise

    ously from the sensor to the pump. Control options of E-pumpsCommunication with CRE, CRIE, CRNE pumps is possibleby means of

    a central management system,

    remote control (Grundfos R100) or

    a control panel.

    The purpose of controlling an E-pump is to monitor andcontrol the pressure, temperature, flow and liquid levelof the system.

    Central management system

    Communication with the E-pump is possible eventhough the operator is not present near the E-pump.Communication is enabled by having connected the E-pump to a central management system allowing theoperator to monitor and change control modes andsetpoint settings of the E-pump.

    Fig. 6 Structure of a central management system

    Remote control

    The R100 remote control produced by Grundfos is avail-able as an accessory.

    The operator communicates with the E-pump bypointing the IR-signal transmitter at the control panel ofthe E-pump terminal box.

    Fig. 7 R100 remote control

    On the R100 display it is possible to monitor and changecontrol modes and settings of the E-pump.

    Control panel

    The control panel of the E-pump terminal box makes itpossible to change the setpoint settings manually.

    Control of E-pumps Vertical multistage centrifugal pumps

    CRE, CRIE and CRNE pumps can be fitted with sensortypes listed on page 75.The pump responds to the signals by adjusting itsperformance up or down to compensate for the pressuredifference between the actual and the desired pressure.As this adjustment is a continuous process, a constantpressure is maintained in the piping system.

    Fig. 9 CRE, CRIE and CRNE pumps

    A CRE, CRIE or CRNE pump with integrated pressuresensor facilitates installation and commissioning. CRE,CRIE and CRNE pumps with integrated pressure sensorcan be set to:

    constant-pressure mode (factory setting) or

    constant-curve mode.

    In constant-pressure mode, the pump maintains apreset pressure after the pump, irrespective of the flow,see figure below.

    Fig. 10 Constant pressure mode

    In constant-curve mode, the pump is not controlled. Itcan be set to pump according to a preset pump charac-teristic within the range from min. curve to max. curve,see figure below.

    Fig. 11 Constant curve mode

    CRE, CRIE and CRNE without sensor

    CRE, CRIE and CRNE pumps without sensor are suitablefor applications where

    uncontrolled operation is required

    you want to fit another sensor later in order to con-trol the flow, temperature, differential temperature, liquid level, pH value, etc at some arbitrary point in the system.

    CRE, CRIE and CRNE pumps without sensor can be set to:

    controlled-operation mode or

    uncontrolled-operation mode (factory-setting).

    In controlled-operation mode, the pump adjusts itsperformance to the desired setpoint, see figure below.

    Fig. 12 Constant flow mode

    In uncontrolled-operation mode, the pump operatesaccording to the constant curve set, see figure below.

    Operating and inlet pressure Vertical multistage centrifugal pumpsMaximum inlet pressureThe following table shows the maximum permissibleinlet pressure. However, the current inlet pressure + thepressure against a closed valve must always be lowerthan the maximum permissible operating pressure.

    If the maximum permissible operating pressure isexceeded, the conical bearing in the motor may bedamaged and the life of the shaft seal reduced.

    Example of operating and inlet pressures

    The values for operating and inlet pressures shown inthe tables must not be considered individually but mustalways be compared, see the following examples:

    Example 1:

    The following pump type has been selected:CR 3-10 A-A-A

    Max. operating pressure: 232 psiMax. inlet pressure: 145 psi

    Discharge pressure against a closed valve: 139.2 psi, seepage 33.

    This pump is not allowed to start at an inlet pressure of145 psi, but at an inlet pressure of 232.0 139.2 = 92.8psi.

    Example 2:

    The following pump has been selected:CR 10-2 A-GJ-A

    Max. operating pressure: 232 psiMax. inlet pressure: 116 psi

    Discharge pressure against a closed valve: 42 psi (97 H[ft]), see page 41.

    This pump is allowed to start at an inlet pressure of 116psi, as the discharge pressure is only 42 psi, which resultsin an operating pressure of 116 + 42 = 158 psi. On thecontrary, the max. operating pressure of this pump islimited to 158 psi, as a higher operating pressure willrequire an inlet pressure of more than 116 psi.

    In case the inlet or operating pressure exceeds the pres-sure permitted, see "Lists of variants - on request"page 76.

    Vertical multistage centrifugal pumpsSelection and sizing

    For calculation of the NPSH value, see "Minimum inlet pressure - NPSH" page 22.

    Fig. 19 Sizing data

    TMSelection of pumpsSelection of pumps should be based on

    The duty point of the pump (see section 1)

    Sizing data such as pressure loss as a result of height differences, friction loss in the pipework, pump effi-ciency etc. (see section 2)

    Pump materials (see section 3)

    Pump connections (see section 4)

    Shaft seal (see section 5).

    1. Duty point of the pump

    From a duty point it is possible to select a pump on thebasis of the curve charts shown in the chapter of"Performance curves/Technical data" on pages 24-63.

    Fig. 16 Example of a curve chart

    2. Sizing data

    When sizing a pump the following must be taken intoaccount.

    Required flow and pressure at the point of use.

    Pressure loss as a result of height differences (Hgeo).

    Friction loss in the pipework (Hf).It may be necessary to account for pressure loss in connection with long pipes, bends or valves, etc.

    Best efficiency at the estimated duty point.

    NPSH value.

    Efficiency

    Before determining the point of best efficiency the oper-ation pattern of the pump needs to be identified. Is thepump expected to operate at the same duty point, thenselect a CR pump which is operating at a duty pointcorresponding with the best efficiency of the pump.

    Fig. 17 Example of a CR pumps duty point

    As the pump is sized on the basis of the highest possibleflow, it is important to always have the duty point to theright of the optimum efficiency point (see fig. 18, rangewith check mark). This must be considered in order tokeep efficiency high when the flow drops.

    Selection and sizing Vertical multistage centrifugal pumpsNormally, E-pumps are used in applications character-ized by a variable flow. Consequently, it is not possibleto select a pump that is constantly operating atoptimum efficiency.

    In order to achieve optimum operating economy, thepump should be selected on the basis of the followingcriteria:

    The max. required duty point should be as close as possible to the QH curve of the pump.

    The required duty point should be positioned so that P2 is close to the max. point of the 100% curve.

    Between the min. and max. performance curve E-pumpshave an infinite number of performance curves eachrepresenting a specific speed. Therefore it may not bepossible to select a duty point close to the 100% curve.

    Fig. 20 Min. and max. performance curves

    In situations where it is not possible to select a dutypoint close to the 100% curve the affinity equations tothe right can be used. The head (H), the flow (Q) and theinput power (P) are all the appropriate variables for themotor speed (n).

    Note:

    The approximated formulas apply on condition that thesystem characteristic remains unchanged for nn and nxand that it is based on the formula H = k x Q2, where k isa constant.

    The power equation implies that the pump efficiency isunchanged at the two speeds. In practice this is notquite correct.

    Finally, it is worth noting that the efficiencies of thefrequency converter and the motor must be taken intoaccount if a precise calculation of the power savingresulting from a reduction of the pump speed is wanted.

    Fig. 21 Affinity equations

    Legend

    WinCAPS and WebCAPS

    WinCAPS and WebCAPS are both selection programsoffered by Grundfos.

    The two programs make it possible to calculate an E-pumps specific duty point and energy consumption.

    By entering the sizing data of the pump, WinCAPS andWebCAPS can calculate the exact duty point and energycomsumption. For further information see page 79 andpage 80.

  • Selection and sizing Vertical multistage centrifugal pumps3. Material

    The material variant (CR(E), CRI(E), CRN(E)) should beselected based of the liquid to be pumped. The productrange covers three basic types.

    The CR(E), CRI(E) pump types are suitable for clean, non-aggressive liquids such as potable water, oils, etc.

    The CRN(E) pump type is suitable for industrial liq-uids and acids, see "List of pumped liquids" on page 67 or contact Grundfos.

    For saline or chloride-containing liquids such as seawater, CRT(E) pumps of titanium are available.

    4. Pump connection

    Selection of pump connection depends on the ratedpressure and pipework. To meet any requirement theCR(E), CRI(E) and CRN(E) pumps offer a wide range offlexible connections such as:

    Oval flange (NPT)

    ANSI flange

    PJE coupling

    Clamp coupling

    Union (NPT[M])

    Other connections on request.

    5. Shaft seal

    As standard, the CR(E) range is fitted with a Grundfosshaft seal (Cartridge type) suitable for the most commonapplications.

    The following three key parameters must be taken intoaccount, when selecting the shaft seal:

    Type of pumped liquid

    liquid temperature and

    maximum pressure.

    Grundfos offers a wide range of shaft seal variants tomeet specific demands see "List of pumped liquids" onpage 67.

    Inlet pressure and operating pressure

    The limit values stated on page 16 and page 18 must notbe exceeded as regards ...

    maximum inlet pressure and

    maximum operating pressure.

    Selection and sizing Vertical multistage centrifugal pumpsMinimum inlet pressure - NPSHR

    Calculation of the inlet pressure "H" is recommendedwhen ....

    the liquid temperature is high,

    the flow is significantly higher than the rated flow,

    water is drawn from depths,

    water is drawn through long pipes,

    inlet conditions are poor.

    To avoid cavitation, make sure that there is a minimumpressure on the suction side of the pump. The maximumsuction lift "H" in feet can be calculated as follows:

    H = pb x 10.2 NPSHR Hf Hv Hs

    pb = Barometric pressure in psi. (Barometric pressure can be set to 14.5 psi). In closed systems, pb indicates the system pressure in psi.

    NPSHR = Net Positive Suction Head Required in feet. (To be read from the NPSHR curve at the highest flow the pump will be delivering).

    Hf = Friction loss in suction pipe in feet. (At the highest flow the pump will be delivering.)

    Hv = Vapour pressure in feet. (To be read from the vapour pressure scale. "Hv" depends on the liquid temperature "Tm").

    Hs = Safety margin = minimum 2.0 feet.

    If the "H" calculated is positive, the pump can operate ata suction lift of maximum "H" feet.

    If the "H" calculated is negative, an inlet pressure ofminimum "H" feet is required.

    Fig. 26 Minimum inlet pressure - NPSHR

    Note: In order to avoid cavitation never, select a pumpwhose duty point lies too far to the right on the NPSHRcurve.

    Always check the NPSHR value of the pump at thehighest possible flow.

    In case a lower NPSHR value is required, see "List of vari-ants, on request" page 76.

  • Selection and sizing Vertical multistage centrifugal pumpsHow to read the curve charts

    Fig. 27 How to read the curve charts

    Guidelines to performance curvesThe guidelines below apply to the curves shown on thefollowing pages:

    1. The motors used for the measurements are standard motors (ODP, TEFC or MLE).

    2. Measurements have been made with airless water at a temperature of 68F.

    3. The curves apply to a kinematic viscosity of = 1 mm2/s (1 cSt).

    4. Due to the risk of overheating, the pumps shouldnot be used at a flow below the minimum flow rate.

    5. The QH curves apply to a rated motor speed of 3500 rpm. All curves are based on current motor speeds.

    The curve below shows the minimum flow rate as apercentage of the nominal flow rate in relation to theliquid temperature. The dotted line shows a CR pumpfitted with an air-cooled top assembly.
