3 General data E-ums Grundfos ums equied with Grundfos MGE or MMGE motors are called E-ums. CRE, CRIE and CRNE ums belong to the E-ums family. Pums of a motor size u to and including. kw are fitted with the single-hase Grundfos MGE motor. Pums of a motor size of. kw or more are fitted with the three-hase MGE ( kw) or MMGE (- kw) motor. Both the MGE and MMGE motors offer the following features: Built-in PI-controller, otional connection to external control signals, setoint setting on the unit itself, and communication with the Grundfos remote control R. Through frequency control the MGE or MMGE motors enable continuously variable control of the motor seed. Thus the um can oerate in any duty oint in the range between um min. and max. erformance curves. Q [m³/h] with ressure sensor TM 9 99 CRE ums are sulied with or without ressure sensor fitted. Some CRE and CRNE versions are available with increased rated seed ( min ). The comlete roduct range is shown in the table below and in the erformance curves in the following ages: Pum tye Number of hases Pressure sensor fitted Rated seed [min ] Performance curves See age...

Page and CRNE Page For alications requiring a constant ressure, a CRE with ressure sensor fitted offers a comact solution which is easy to install and start u. The ressure required can be set directly on the um. It is also ossible to change um oerating mode from controlled to uncontrolled (constant seed). E-ums without sensor should be used when there is a need for uncontrolled oeration, or when control arameters are other than the um discharge ressure. Such arameters could be flow, temerature, differential temerature, ressure or differential ressure at any lace in the system. CRE, CRNE ums with increased seed ( min ) offer an ideal solution in alications requiring high head and small dimensions. The increased um seed means that for a given required head the number of um stages and thus the um dimensions can be reduced. Controlled oeration Uncontrolled oeration Uncontrolled oeration set Constant ressure Q Constant curve Q TM 9 9 Constant curve Q TM The fitting of a sensor at a later stage oens the ossibility of control on the basis of ressure, differential ressure, temerature, differential temerature or flow.

20 General data Pum The CRE um is a non-self-riming, vertical, multistage, centrifugal um fitted with a Grundfos MGE or MMGE motor. The um consists of a base and a um head. The chamber stack and the outer sleeve are secured between the um head and the base by means of staybolts. The base has suction and discharge orts on the same level (in-line). All ums are equied with a maintenance-free mechanical shaft seal. Qmin [%] CR t [ C] TM. If the umed liquid density and/or viscosity is higher than that of water, it may be necessary to use a motor with a higher erformance. Shaft seal Base Curve conditions Pum head Staybolts The guidelines below aly to the erformance curves from age :. All curves state mean values according to ISO 99, Annex A. If secification of minimum erformance is required, individual measurements must be made. The curves aly to a kinematic viscosity of mm²/s ( cst). Measurements were made at a water temerature of C. Test liquid: Air-free water.. The conversion between head (m) and ressure (mpa) alies to water with a density of ρ = kg/m³. In the case of a density other than kg/ m³, the discharge ressure is roortional to the density. The ums should not be used at a minimum flow rate lying outside the areas indicated by the boldfaced curves due to danger of um overheating. The curve below shows the minimum flow rate as a ercentage of the nominal flow rate in relation to the liquid temerature. The dotted line shows a um fitted with a cool to assembly. TM Performance curves The curve charts on the following ages show Q-curves and QP -curves for %, 9%, %, 7%, %, % and % seed.

27 Selection and sizing Selection of ums Pum size and efficiency The um must be able to fulfil the max. required flow and ressure, see oint,, on the curve. : Max. head : Max. flow : Duty oint Normally, E-ums are used in alications characterized by a variable load (flow). Consequently, it is not ossible to select a um which is constantly oerating at otimum efficiency. In order to ensure otimum oerating economy, the um should be selected on the basis of the following criteria: The max. required duty oint (see oint in the chart) should be as close as ossible to the % Qcurve of the um. Point should be ositioned so that is close to the max. oint of the % curve (see oint in the chart). As a rule of thumb ies should be dimensioned in such a way that the velocity of the liquid does not exceed to. m/sec. % 9 % % 7 % % % CRE / CRNE Q [m³/h] % Q [m³/h] The um must be able to fulfil the flow and ressure requirements. Check that the highest efficiency falls within the marked duty range. TM 99 Material The material variant () should be selected on the basis of the liquid to be umed. The roduct range covers three basic tyes. The CRE, CRIE um tyes are suitable for clean, nonaggressive liquids such as otable water, oils, etc. The CRNE um tye is suitable for industrial liquids (see "List of umed liquids", age 99). TM 99 7

28 Selection and sizing Pum connection Selection of um connection deends on rated ressure and iework. To meet any requirement the CRE, CRIE and CRNE ums offer a wide range of flexible connections such as: Oval flange (BSP) flange PJE couling Clam couling Other connections on request. Oval PJE TM Shaft seal As standard, the CRE range is fitted with a Grundfos shaft seal suitable for the most common alications. The following three key arameters must be taken into account, when selecting the shaft seal: tye of umed liquid liquid temerature and maximum ressure. Grundfos offers a wide range of shaft seal variants to meet secific demands (see "List of umed liquids", age 99). TM Inlet ressure and oerating ressure It should be checked whether the ressure conditions are fulfilled.

30 Alications Examles of alications CRE, CRIE and CRNE ums are the ideal solution in a number of alications characterized by a need for variable flow at constant ressure. The ums are suited for water suly systems and ressure boosting, but also industrial alications such as ressure boosting in water treatment systems are obvious for these ums. Deending on the nature of the alication, the ums offer energy savings, increased comfort or imroved rocessing. A comact one-um booster A comact booster unit is the CRE featuring an integrated sensor and a small diahragm tank. These comonents make u a comlete ressure boosting system which is indeendent of the load and maintains a constant ressure. CRE incororates a sto function to ensure that the um automatically stos if the water demand dros to a very low level or disaears altogether. The method gives good total oerating economy irresective of the water demand, and the um is not subjected to overheating and the subsequent risk of damage to the shaft seal. CRE as the basis of bigger ressure boosting systems Pressure boosting systems based on arallel couled ums of which one or more are CRE ums, also available from Grundfos. This range of boosters has the name ydro and incororates E-ums tye CRE as a very imortant element. The ydro E range includes booster systems solely with seed-controlled ums tye CRE and systems with one or more seed-controlled CRE ums. Two examles: TM TM & TM A ydro E booster system can be used for a number of alications. For further information, see the ydro data booklet or contact Grundfos. E-ums in the service of industry Countless ums are oerating in industry today, and for many of them seed regulation would be an advantage. In industrial cleaning and similar alications a further advantage can be gained by ensuring a constant ressure. Other alications such as circulation of cooling water, ressure boosting or other rocess related um alications would in many cases be good alications for E- ums. Water treatment installation Water treatment is an obvious alication for a seedcontrolled CRNE um. The combination of a stainless steel um and a seed-controlled um makes it ossible to satisfy material secifications, while roviding otimised oerations, minimising energy consumtion, etc. A CRNE um is very suitable as the high-ressure um in a reverse osmosis lant. If exosed to varying umed liquid temerature and thus varying viscosity an uncontrolled um will yield a varying flow. An E-um, however, controlled by a flow sensor ensures a constant flow resulting in imroved system erformance of the reverse osmosis lant. In a system with a seed-controlled suly um a beginning choking u of the filters will not result in a lower caacity of the system. The um will just seed u and maintain a constant flow to the clean water tank. An E-um will also be advantageous as suly um for the clean water tank. A CRE or a CRNE with a ressure transmitter connected can ensure a comfortable constant-ressure water suly. The built-in sto function will ensure that the um is stoed when there is low or no flow in the system. TM

32 Functions Control modes with sensor CRE ums with integrated ressure sensor enable control of the ressure sulied by the um. The um can be set to two control modes, i.e. constant ressure mode or constant-curve mode. In constant-ressure mode the um will maintain a constant ressure on the discharge side of the um, irresective of the flow. In constant-curve mode, the um is not controlled. The curve can be set within the range from min. curve to max. curve. Controlled oeration Uncontrolled oeration without sensor ums can be connected to an external sensor enabling control of ressure, differential ressure, temerature, differential temerature or flow. ums can be set to two control modes, controlled or uncontrolled oeration. In controlled oerating mode the um is automatically oerating according to the desired setoint of the control arameter. The illustration below shows a um with flow control as an examle of controlled oeration. In uncontrolled oerating mode the um oerates according to the constant curve set. Controlled oeration Uncontrolled oeration set Constant ressure Q Q Constant curve The ums are set to constant-ressure mode from factory.

The remote control R offers additional osibilities of settings and status readings. The ums are set to constant ressure from factory. The setoint value corresonds to % of the sensor measuring range. The max. curve can for instance be used in connection with the venting rocedure during installation. The min. curve can be used in eriods in which a minimum flow is required. The oerating modes (Sto, Normal, Min., Max.) can all be set on the control anel on the um terminal box. If the electricity suly to the um is disconnected, the um setting will be stored. The remote control R offers additional ossibilities of setting and status dislays. The ums are set to uncontrolled oeration from factory. The setoint value corresonds to %.

If s is selected, the controller will function as a P-controller The gain (K) and intergral-action time (T i ) of the builtin PI-controller can be changed, should factory settings be inadequate. Furthermore, it is ossible to set the controller to inverse control (if the setoint is increased, the seed will be reduced). In the case of inverse control, the gain (K) must be set within the range from. to.. Selection of external setoint signal Select one of the following tyes: - V (~ ums only) V - ma - ma Not active.

Locking of the buttons on the um The buttons "+" and " " on the um can be set to: Active, Not active.. Allocation of um number A number between and can be allocated to the um. In the case of BUS communication, a number must be allocated to each um..7 Selection of function for digital inut Select one of the following functions: Min. (min. curve) Max. (max. curve) Ext. fault (external fault) Flow switch. The selected function is activated by closing the contact between the following terminals: and 9 of single-hase ums and of three-hase ums. See "Other connetions" age. Min.: When the inut is activated, the um is oerating according to the min. curve. Max.: When the inut is activated, the um is oerating according to the max. curve. Ext. fault: When the inut is activated, a timer is started. If the inut is activated for more than secs., the um is stoed and a fault is indicated. If the connection is disconnected for more than secs., the fault condition will cease and the um can be restarted manually by resetting the fault indication. The tyical alication will be detection of missing inlet ressure or water shortage by means of a ressure switch installed on the suction side of a um. Flow switch: When this function is active, the um will be stoed when a connected flow switch detects a low flow. It is only ossible to use this function if the um is connected to a ressure sensor. When the inut is activated for more than secs., the sto function incororated in the um will take over, see "Setting of sto function" age 7.

37 Functions. Setting of sto function The sto function can be set to: Active Not active. When the sto function is active, the um will be stoed at very low flows to avoid unnecessary ower consumtion. It is only ossible to use this function if the um is connected to a ressure sensor. There are two ossibilities of low-flow detection:. A "low-flow detector" which automatically starts functioning if no flow switch is chosen/connected to the digital inut. The um will check the flow regularly by reducing the seed for a short time, thus checking the change in ressure. If there is no or a small change in ressure, the um will detect a low flow.. A flow switch connected to the digital inut. When the inut is activated for more than secs., the sto function of the um will take over. Unlike the built -in low-flow detector, the flow switch measures the minimum flow at which the um must sto. The um will not check the flow regularly by reducing the seed. When the um detects a low flow, the seed will be increased until the sto ressure (actual setoint +. x ) is reached and the um stos. When the ressure has fallen to the start ressure (actual setoint. x ), the um will restart. indicates the difference between start and sto ressures. The sto function requires a diahragm tank of a certain minimum size. The tank must be installed immediately after the um and the recharge ressure must be.7 x actual setoint. Recommended diahragm tank size when no flow switch is connected. Rated flow of um [m /h] Diahragm tank size [litres] If a diahragm tank of the above size is installed in the system, the factory setting of is the correct setting. If the tank installed is too small, the um will start and sto too often. This can be remedied by increasing..9 Setting of sensor Note: Alies only to without sensor. Select the following: Sensor outut signal (- V (~ ums only), V, - ma or - ma), sensor measuring unit (bar, mbar, m, kpa, si, ft, m /h, m /s, l/s, gm, C, F or %) and sensor measuring range. The setting of the sensor is only carried out in the case of controlled oeration.. Setting of min. and max. curves Note: Alies only to without sensor. Sto ressure Start ressure is factory-set to % of actual setoint. can be set within the range from % to % of actual setoint. Note: The non-return valve must be fitted immediately before the um. If the non-return valve is fitted between um and diahragm tank, the ressure sensor must be fitted after the non-return valve. Correctly installed non-return valve Pum Diahragm tank Q TM 77 9 TM 77 9 Set the min. and max. curves in % of maximum erformance if the oerating range must be reduced. % Max. curve Min. curve % Oerating range The max. curve can be adjusted within the range from maximum erformance (%) to min. curve.
