Product data CR, CRI, CRN, CRE, CRIE, CRNE Introduction This data booklet deals with CR, CRI and CRN as well as CRE, CRIE and CRNE pumps. CRE, CRIE, CRNE TM 7397 33 Fig. 1 CR, CRI and CRN pumps CR, CRI, CRN CR, CRI and CRN pumps are vertical multistage centrifugal pumps. The in-line design enables the pump to be installed in a horizontal one-pipe system where the suction and discharge ports are in the same horizontal plane and have the same pipe dimensions. This design provides a more compact pump design and pipework. Grundfos CR pumps are available in various sizes and various numbers of stages to provide the flow and pressure required. CR pumps are designed for a variety of applications from the pumping of potable water to the pumping of chemicals. The pumps are therefore suitable for a wide diversity of pumping systems where the performance and material of the pump meet specific demands. The CR pumps consist of two main components: The motor and the pump unit. The CR pump motor is a Grundfos motor designed to EN standards. The pump unit consists of optimised hydraulics, various types of connections, a sleeve, a pump head and various other parts. CR pumps are available in various material versions according to the pumped liquid. GR 5381 Fig. CRE, CRIE and CRNE pumps CRE, CRIE and CRNE pumps are built on the basis of CR, CRI, CRN pumps. CRE, CRIE and CRNE pumps belong to the so-called E-pump family. CRE, CRIE and CRNE pumps are referred to as E-pumps. The difference between the CR and the CRE pump range is the motor. CRE, CRIE and CRNE pumps are fitted with an E-motor, i.e. a motor with built-in frequency control. The CRE pump motor is a Grundfos MGE or MMGE motor designed to EN standards. Frequency control enables continuously variable control of motor speed, which makes it possible to set the pump to operation at any duty point. The aim of continuously variable control of the motor speed is to adjust the performance to a given requirement. CRE, CRIE and CRNE pumps are available with an integrated pressure sensor connected to the frequency control. The pump materials are identical to those of the CR, CRI and CRN pump range. Selecting a CRE pump Select a CRE pump if the following features are required: Controlled operation, i.e. consumption fluctuates Constant pressure Communication with the pump. Adaptation of performance through frequencycontrolled speed control offers obvious benefits such as: energy savings increased comfort control and monitoring of the pump performance. 3

Product data CR, CRI, CRN, CRE, CRIE, CRNE Motor protection MG and Siemens motors Single-phase Grundfos motors have a built-in thermal overload switch (IEC 3-11: TP 11). Three-phase motors must be connected to a motor starter in accordance with local regulations. Three-phase Grundfos motors as from 3 kw have a built-in thermistor (PTC) according to DIN 8 (IEC 3-11: TP 11). MGE motors CRE, CRIE, CRNE pumps require no external motor protection. The MGE motor incorporates thermal protection against slow overloading and blocking (IEC 3-11: TP 11). Terminal box positions As standard the terminal box is mounted on the suction side of the pump. Position 6 Standard Position 9 Position 1 Position 3 Fig. Terminal box positions TM3 3658 66 Ambient temperature Motor power [kw] If the ambient temperature exceeds the above temperature values or the pump is installed at an altitude exceeding the above altitude values, the motor must not be fully loaded due to the risk of overheating. Overheating may result from excessive ambient temperatures or 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 rated output. 1 5 35 75 m Fig. 5 Motor output depends on temperature/altitude Viscosity Motor make Motor efficiency class Maximum ambient temperature [ C] Maximum altitude above sea level.37 -.75 Grundfos MG EFF + 1 1.1 - Grundfos MG EFF1 +6 35 3-75 Siemens EFF1 +55 75 [%] EFF 1, Siemens 1 EFF 1, MG 9 8 EFF, MG 7 6 5 5 3 35 5 5 55 6 65 7 75 8 t [ C] The pumping of liquids with densities or kinematic viscosities higher than those of water will cause a considerable pressure drop, a drop in the hydraulic performance and a rise in the power consumption. In such situations the pump should be equipped with a larger motor. If in doubt, contact Grundfos. TM3 1868 335 9

Control of E-pumps CR, CRI, CRN, CRE, CRIE, CRNE Examples of E-pump applications CRE, CRIE and CRNE pumps are the ideal choice for a number of applications characterised by a need for variable flow at constant pressure. The pumps are suited for water supply systems and pressure boosting as well as for industrial applications. Depending on the application, the pumps offer energysavings, increased comfort and improved processing. E-pumps in the service of industry Industry uses a large number of pumps in many different applications. Demands on pumps in terms of pump performance and mode of operation make speed control a must in many applications. Below is listed some of the applications in which E-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 with integrated pressure sensor are used to ensure a constant pressure in the piping network. From the sensor, the E-pump receives inputs about changes of pressure as a result of changes in the consumption. The E-pump responds to the input by adjusting the speed until the pressure is equalized. The constant pressure is stabilized once 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 with temperature sensor increase comfort and lower operating costs compared with pumps without a temperature sensor. An E-pump continuously adapts its performance to the changing demands reflected in the differences in temperature of the liquid circulating in the freezing system. Thus, the lower the demand for cooling, the smaller the quantity of liquid circulated in the system and vice versa. Constant flow steam boiler systems condensate systems sprinkler irrigation systems chemical industry, etc. Example: In a steam boiler, it is important to be able to monitor and control pump operation to maintain a constant level of water in the boiler. By using an E-pump with level sensor in the boiler, it is possible to maintain a constant water level. A constant water level ensures optimum and cost-efficient operation as a result of a stable steam production. Dosing applications chemical industry (i.e. control of p-values) petrochemical industry paint industry degreasing systems bleaching systems, etc. Example: In the petrochemical industry, E-pumps with pressure sensor are used as dosing pumps. The E-pumps helps to ensure that the correct mixture ratio is achieved when more liquids are combined. E-pumps functioning as dosing pumps improves processing and offer energy-savings. E-pumps in commercial building services Commercial building services use E-pumps to maintain a constant pressure or a constant temperature based on a variable flow. Constant pressure Water supply in high-rise buildings such as office buildings and hotels. Example: E-pumps with pressure sensor are used for water supply in high-rise buildings to ensure a constant pressure even at the highest draw-off point. As the consumption pattern and thus the pressure changes during the day, the E-pump continuously adapts its performance until the pressure is equalized. Constant temperature air-conditioning systems in hotels, schools, etc. building cooling systems, etc. Example: E-pumps are an excellent choice for buildings where constant temperature is essential. E-pumps keep the temperature constant in air-conditioned highrise glass buildings, irrespective of the seasonal fluctuations of the outdoor temperature and various heat impacts inside the building. 1

Control of E-pumps CR, CRI, CRN, CRE, CRIE, CRNE Control options of E-pumps Communication with CRE, CRIE, CRNE pumps is possible by means of either of the following: a central management system remote control (Grundfos R1) a control panel. The purpose of controlling an E-pump is to monitor and control the pressure, temperature, flow and liquid level of the system. Remote control The R1 remote control produced by Grundfos is available as an accessory. The operator communicates with the E-pump by pointing the IR-signal transmitter at the control panel of the E-pump terminal box. Central management system Communication with the E-pump is possible even if the operator is not present near the E-pump. Communication is enabled by connecting the E-pump to a central management system. This allows the operator to monitor the pump and to change control modes and setpoint settings. Fig. 7 R1 remote control On the R1 display it is possible to monitor and change control modes and settings of the E-pump.

Control of E-pumps CR, CRI, CRN, CRE, CRIE, CRNE Control modes for E-pumps Grundfos offers CRE, CRIE and CRNE pumps in two different variants: CRE, CRIE and CRNE with integrated pressure sensor CRE, CRIE and CRNE without sensor. CRE, CRIE, CRNE with integrated pressure sensor Use CRE, CRIE and CRNE pumps with integrated pressure sensor in applications where you want to control the pressure after the pump, irrespective of the flow. For further information, see the section Examples of E-pump applications, page 1. Signals of pressure changes in the piping system are transmitted continuously from the sensor to the pump. The pump responds to the signals by adjusting its performance up or down to compensate for the pressure difference between the actual and the desired pressure. As this adjustment is a continuous process, a constant pressure is maintained in the piping system. In constant-curve mode, the pump is not controlled. It can be set to pump according to a preset pump characteristic within the range from min. curve to max. curve. See figure below. Min. Fig. 11 Constant curve mode Max. CRE, CRIE and CRNE without sensor CRE, CRIE and CRNE pumps without sensor are suitable for applications where uncontrolled operation is required where you want to fit another sensor later in order to control the flow, temperature, differential temperature, liquid level, p value, etc. at some arbitrary point in the system. CRE, CRIE and CRNE pumps without sensor can be set to either of these modes: controlled-operation mode uncontrolled-operation mode (factory-setting). In controlled-operation mode, the pump adjusts its performance to the desired setpoint. See figure below. Q TM 933 1 TM 7398 33 Max. Fig. 9 CRE, CRIE and CRNE pumps A CRE, CRIE or CRNE pump with integrated pressure sensor facilitates installation and commissioning. CRE, CRIE and CRNE pumps with integrated pressure sensor can be set to either of these modes: constant-pressure mode (factory setting) constant-curve mode. In constant-pressure mode, the pump maintains a preset pressure after the pump, irrespective of the flow. See figure below. Min.

This pump is allowed to start at an inlet pressure of 8. bar, as the discharge pressure against a closed valve is only. bar, which results in an operating pressure of 8. +. = 1. bar. On the contrary, the max. operating pressure of this pump is limited to 16. bar, as a higher operating pressure will require an inlet pressure of more than 8. bar. In case the inlet or operating pressure exceeds the pressure permitted, see "Variants on request", page 89. 18

Selection and sizing CR, CRI, CRN, CRE, CRIE, CRNE Selection of pumps Selection of pumps should be based on these elements: the duty point of the pump (see page 19) dimensional data such as pressure loss as a result of height differences, friction loss in the pipework, pump efficiency etc. (see page 19) pump materials (see page 1) pump connections (see page 1) shaft seal (see page 1).

Selection and sizing CR, CRI, CRN, CRE, CRIE, CRNE Normally, E-pumps are used in applications characterized by a variable flow. Consequently, it is not possible to select a pump that is constantly operating at optimum efficiency. Q n n n ------- ------ Q n x x In order to achieve optimum operating economy, the pump should be selected on the basis of the following criteria: The max. duty point required should be as close as possible to the Q curve of the pump. The flow rate at the duty point required should be close to the optimum efficiency (eta) for most operating hours. Between the min. and max. performance curve, E-pumps have an infinite number of performance curves each representing a specific speed. Therefore it may not be possible to select a duty point close to the 1 % curve. n x Q x n n n x Q n n x n n Q n n n ------- ------ n x x ------ n 1 x Q P Q x Q n Max. curve P n n n P n n n 3 ------ = ------ P n x x Min. curve Q [m³/h] TM1 916 83 n Px x Fig. Affinity equations Legend Q TM 87 396 Fig. 19 Min. and max. performance curves In situations where it is not possible to select a duty point close to the 1 % curve the below affinity equations can be used. The head (), the flow (Q) and the input power (P) are all the appropriate variables for the motor speed (n). Note: The approximated formulas apply on condition that the system characteristic remains unchanged for n n and n x and that it is based on the formula = k x Q, where k is a constant. The power equation implies that the pump efficiency is unchanged at the two speeds. In practice, this is not quite correct. To obtain a precise calculation of the power savings resulting from a reduction of pump speed, take into account the efficiencies of the frequency converter and the motor. n Rated head in metres x Current head in metres Q n Rated flow in m 3 /h Q x Current flow in m 3 /h n n Rated motor speed in min -1 (n n = 9 min -1 ) n x Current motor speed in min -1 n Rated efficiency in % x Current efficiency in % WinCAPS and WebCAPS WinCAPS and WebCAPS are both selection programmes offered by Grundfos. The two programmes make it possible to calculate an E-pump s specific duty point and energy consumption. By entering the dimensional data of the pump, Win- CAPS and WebCAPS can calculate the exact duty point and energy consumption. For further information, see pages 9 and 91.

Selection and sizing CR, CRI, CRN, CRE, CRIE, CRNE Pump material Select the material variant (CR(E), CRI(E), CRN(E)) on the basis of the liquid to be pumped. The product range covers the following three basic types. CR(E), CRI(E) Use CR(E), CRI(E) pumps for clean, nonaggressive liquids such as potable water and oils. CRN(E) Use CRN(E) pumps for industrial liquids and acids. See "List of pumped liquids", page 78, or contact Grundfos. For saline or chloride-containing liquids such as sea water, CRT(E) pumps of titanium are available. Pump connections Selection of pump connection depends on the rated pressure and pipework. To meet any requirement, the CR(E), CRI(E) and CRN(E) pumps offer a wide range of flexible connections such as: oval flange (BSP) DIN flange PJE coupling clamp coupling union (+GF+) other connections on request. Fig. 1 CR pump F (DIN) A (oval) Fig. Pump connections P (PJE) TM1 1 1198 TM 11 61 Shaft seal As standard, the CR(E) range is fitted with a Grundfos shaft seal (cartridge type) suitable for the most common applications. These key parameters must be taken into account when selecting the shaft seal: type of pumped liquid liquid temperature maximum pressure. Grundfos offers a wide range of shaft seal variants to meet specific demands. See "List of pumped liquids", page 78.

Selection and sizing CR, CRI, CRN, CRE, CRIE, CRNE Minimum inlet pressure, NPS Calculation of the inlet pressure "" is recommended in these situations: 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 minimum pressure on the suction side of the pump. The maximum suction lift "" in metres head can be calculated as follows: = p b x 1. NPS f v s p b = Barometric pressure in bar. (Barometric pressure can be set to 1 bar). In closed systems, p b indicates the system pressure in bar. NPS = Net Positive Suction ead in metres head. (To be read from the NPS curve at the highest flow the pump will be delivering.) f = Friction loss in suction pipe in metres head. (At the highest flow the pump will be delivering.) v = Vapour pressure in metres head. (To be read from the vapour pressure scale." v " depends on the liquid temperature "T m ".) s = Safety margin = minimum.5 metres head. If the "" calculated is positive, the pump can operate at a suction lift of maximum "" metres head. If the "" calculated is negative, an inlet pressure of minimum "" metres head is required. f Pb v NPS Fig. Minimum inlet pressure - NPS tm ( C) v (m) 19 16 18 1 17 79 16 6 15 5 1 35 3 13 5 1 11 15 1 1 1 8, 9 6, 8 5,, 7 3, 6, 1,5 5 1,,8,6 3,,3, 1,1 Note: To avoid cavitation, never select a pump with a duty point too far to the right on the NPS curve.

Pumped liquids CR, CRI, CRN, CRE, CRIE, CRNE Pumped liquids Thin, non-explosive liquids, not containing solid particles or fibres. The liquid must not chemically attack the pump materials. When pumping liquids with a density and/or viscosity higher than that of water, use oversized motors, if required. Whether a pump is suitable for a particular liquid depends on a number of factors of which the most important are the chloride content, p value, temperature and content of chemicals, oils, etc. Please note that aggressive liquids, such as sea water and some acids, may attack or dissolve the protective oxide film of the stainless steel and thus cause corrosion. The CR(E), CRI(E), CRN(E) pump types are suitable for the following liquids: CR(E), CRI(E) CR(E), CRI(E) pumps are suitable for non-corrosive liquids. Use CR(E), CRI(E) pumps for liquid transfer, circulation and pressure boosting of cold or hot clean water. CRN(E) CRN(E) pumps are suitable for industrial liquids. Use CRN(E) pumps in systems where all parts in contact with the liquid must be made of high-grade stainless steel. CRT(E) CRT(E) pumps are suitable for these liquids: saline liquids hypochlorites acids. For saline or chloride-containing liquids such as sea water or for oxidizing agents such as hypochlorites, Grundfos offers CRT(E) pumps made of titanium. See separate data booklet on CRT(E), accessible in WebCAPS. List of pumped liquids A number of typical liquids are listed below. Other pump versions may be applicable, but those stated in the list are considered to be the best choices. The table is intended as a general guide only and cannot replace actual testing of the pumped liquids and pump materials under specific working conditions. owever, use the list with some caution. Factors such as those mentioned below may affect the chemical resistance of a specific pump version: concentration of the pumped liquid liquid temperature pressure. Take safety precautions when pumping dangerous liquids. Notes D Often with additives. The density and/or viscosity differ from that/those of water. E Take this factor into account when calculating motor output and pump performance. F Pump selection depends on many factors. Contact Grundfos. Risk of crystallisation/precipitation in shaft seal. 1 ighly inflammable liquid. Combustible liquid. 3 Insoluble in water. Low self-ignition point.

Variants CR, CRI, CRN, CRE, CRIE, CRNE Lists of variants - on request Although the Grundfos CR(E), CRI(E), CRN(E) product range offers a number of pumps for different applications, customers require specific pump solutions to satisfy their needs. See following documents: Grundfos CR "Custom-built pumps" catalogue Grundfos "CR, CRN high pressure" data booklet. Below please find the range of options available for customizing the CR(E) pumps to meet the customers demands. Contact Grundfos for further information or for requests other than the ones mentioned below. Motors Variant ATEX motor Motor with anticondensation heating unit Motor with thermal protection Oversize motor -pole motor Shaft seals Variant Shaft seal with FFKM O-ring material Seal with flush, quench seal Air-cooled shaft seal system Double seal with pressure chamber CR MAGdrive Description For operation in hazardous atmospheres, explosion-proof or dust-ignition-proof motors may be required. For operation in humid environments motors with built-in anti-condensation heating unit may be required. Grundfos offers motors with built-in bimetallic thermal switches or temperature-controlled PTC sensors (thermistors) incorporated in the motor windings. Ambient temperatures above C or installation at altitudes of more than 1 metres above sea level require the use of an oversize motor (i.e. derating). Grundfos offers -pole standard motors. Description Shaft seals with FFKM or FXM O-ring material are recommended for applications where the pumped liquid may damage the standard O-ring material. Recommended for applications involving crystallizing, hardening or sticky liquids. Recommended for applications involving extremely high temperatures. No conventional mechanical shaft seal can withstand liquid temperatures of up to 18 C for any length of time. For such applications, Grundfos unique aircooled shaft seal system is recommended. In order to ensure a low liquid temperature around the standard shaft seal, the pump is fitted with a special air-cooled shaft seal chamber. No separate cooling is required. Recommended for applications involving poisonous or explosive liquids. Protects the surrounding environment and the people working in the vicinity of the pump. Consists of two seals mounted in a "back-toback" arrangement inside a separate pressure seal chamber. As the pressure in the chamber is higher than the pump pressure, leakage is prevented. A dosing pump or a special pressure-intensifier generates the seal chamber pressure. Magnetically driven pumps for industrial applications. Key applications are industrial processes involving the handling of aggressive, environmental, dangerous or volatile liquids, e.g. organic compounds, solvents, etc. Pumps Variant orizontally mounted pump Low-temperature pump igh-speed pump up to 7 bar igh-pressure pump up to 7 bar Low-NPS pump (improved suction) Pump with bearing flange Belt-driven pump Pump for pharmaceutical and biotechnological applications Description Connections and other variants Variant Pipe connections TriClamp connection Electropolished pump For safety or height reasons, certain applications, for instance on ships, require the pump to be mounted in the horizontal position. For easy installation the pump is equipped with brackets that support motor and pump. Exposed to temperatures down to C, coolant pumps may require neck-rings with a different diameter in order to prevent impeller drag. For high-pressure applications, Grundfos offers a unique pump capable of generating up to 7 bar. The pump is equipped with a high-speed motor, type MGE. The direction of rotation is the opposite of that of standard pumps, and the chamber stack is turned upside-down, as a result of which the pumped liquid flows in the opposite direction. For high-pressure applications, Grundfos offers a unique double pump system capable of generating a pressure of up to 7 bar pressure. Recommended for boiler-feed applications where cavitation may occur due to poor inlet conditions. The bearing flange is suitable for applications where the inlet pressure is higher than the maximum pressure recommended. The bearing flange increases the life of motor bearings. (Recommended for standard motors.) Belt-driven pumps designed to operate in places with limited space or where no electrical power is available. CRN(E) pumps designed for applications requiring the sterilization and CIP capability of pipes, valves and pumps. (CIP = Cleaning-In-Place.) Description In addition to the wide range of standard flange connections, a 16 bar DIN standard clamping flange is available. Customized flanges are available according to specifications. TriClamp connections are of a hygienic design with a sanitary coupling for use in the pharmaceutical and food industry. To substantially reduce the risk of corrosion of the materials. For use in the pharmaceutical/food industry. 89
