5 Features and benefits NBG, NBGE, NKG, NKGE Features and benefits NBG and NKG pumps present these features and benefits: All NKG pumps are according to ISO The pumps are non-self-priming, single-stage, centrifugal volute pumps with axial suction port, radial discharge port and horizontal shaft. Suction and discharge flanges are PN 16 according to EN Dimensions and rated performance are according to ISO 2858 (16 bar). The NBG pump is close-coupled with a totally enclosed fan-cooled standard motor with main dimensions to IEC and DIN standards The NKG pump is long-coupled with a totally enclosed fan-cooled standard motor with main dimensions to IEC and DIN standards and mounting designation B3 (IM 1. The mechanical shaft seal has dimensions according to EN NBG and NKG pumps offer flow rates from 2 to 12 m 3 /h and heads from 2 to 16 m. Motor sizes fall in the.25 to 355 kw range. Pumps with power requirement of 1.1 to 22 kw are available with motors with built-in frequency converter. These pumps are called NBGE and NKGE. All pumps are statically balanced according to ISO 194 class 6.3. Impellers are hydraulically balanced. The NKG pump and motor are mounted on a common, steel base frame in accordance with EN The NBG and NKG product ranges are available in two product series, "standard range" and "premium range". Premium-range products are available with EFF1 motors; standard-range products with EFF2 motors. The pumps are of the back pull-out design enabling removal of the motor, coupling, bearing bracket and impeller without disturbing the pump housing or pipework. Even the largest pumps can thus be serviced by a single person with a crane. See fig. 1 and fig. 2. Fig. 1 NBG back pull-out design Fig. 2 NKG back pull-out design High-efficiency motors Premium range 2- and 4-pole NBG and NKG pumps with motor sizes from 1.1 to 9 kw are fitted with highefficiency motors (EFF. EFF1 is the highest efficiency class defined by CEMEP (European Committee of Manufacturers of Electrical Machines and Power Electronics). TM TM

6 Features and benefits NBG, NBGE, NKG, NKGE Pumps with electronic speed control NBG and NKG pumps equipped with a motor with builtin frequency converter and the necessary application software to achieve an all-in-one solution enable electronic speed control. These pumps are called NBGE and NKGE. Electronic speed control enables continuously variable control of motor speed which again enables adaptation of the performance to a given requirement. The pump materials of NBGE and NKGE pumps are the same as those of the NBG and NKG pump range. If a sensor is installed, NBGE and NKGE pumps allow for any of these configurations and control methods: constant pressure temperature control constant flow. Why select an NBGE, NKGE pump? Select an NBGE, NKGE pump if controlled operation is required constant pressure is required communication with the pump is required. This furthermore gives these obvious advantages: energy savings increased comfort. For further information on electronic speed control, see section "Speed-controlled NBG and NKG pumps" on page 33. ATEX-approved NBG and NKG pumps On request, Grundfos offers NBG and NKG pumps with ATEX-approval in accordance with Directive 94/9/EC (group II, category 3G and 3D). If an ATEX-approved dry-running protection is installed, the pump can be upgraded to category 2G. 6

24 Construction NBG, NBGE, NKG, NKGE A base frame prepared for grouting is available as an option, see "Foundation (NKG)" on page 3. Surface treatment NBG and NKG The cast-iron parts of NBG and NKG have an epoxybased coating made in a cathodic electro-deposition (CED) process. CED is a high-quality dip-painting process where an electrical field around the products ensures deposition of paint particles as a thin, well-controlled layer on the surface. An integral part of the process is a pretreatment. The entire process consists of these elements: 1. Alkaline-based cleaning. 2. Zinc phosphating. 3. Cathodic electro-deposition. 4. Curing to a dry film thickness μm. The colour code for the finished product is NCS 9/ RAL 95. For low-temperature applications at high humidity Grundfos offers NBG and NKG pumps with extra surface treatment to avoid corrosion. These pumps are available on request. Test pressure Pressure testing was made with +2 C water containing corrosion inhibitor. Pressure Operating pressure Test pressure stage bar MPa bar MPa PN Motor The motor is a totally enclosed, fan-cooled standard motor with main dimensions according to IEC and DIN standards. The tables below show the motors available for NBG and NKG. As appears from the tables you can choose between standard range with EFF2 (efficiency 2) motors and premium range with EFF1 (efficiency motors for NBG and NKG, and E-motor range for NBGE and NKGE.

26 Operating conditions NBG, NBGE, NKG, NKGE Pump location The pump is designed for installation in a non-aggressive and non-explosive atmosphere. The relative air humidity must not exceed 95%. Sound pressure level Maximum sound pressure level [db(a)] - ISO 3743 Motor [kw] Three-phase motors 2-pole 4-pole 6-pole Ambient temperature and altitude The ambient temperature and the installation altitude are important factors for the motor life, as they affect the life of the bearings and the insulation system. Ambient temperature must not exceed: +4 C for EFF2 motors +6 C for EFF1 motors. If the ambient temperature exceeds +4 C (+6 C) or if the motor is installed more than 1 m (35 m) above sea level, the motor must not be fully loaded due to 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 output. P2 [%] 1 9 EFF 1 8 EFF t [ C] m Fig. 16 Motor P2 depends on temperature/altitude Example: Fig. 16 shows that the load of an EFF2-motor must be reduced to 88% when installed 35 m above sea level. At an ambient temperature of 7 C the load of an EFF2- motor must be reduced to 78% of the rated output. In such situations an oversize motor can be used. Pumped liquids NBG and NKG pumps are suitable for pumping clean, thin and non-explosive liquids, not containing any solid particles. The effect of viscosity on centrifugal pump performance A viscous liquid affects a centrifugal pump in several ways. The power consumption will be increased, i.e. a larger motor is required. Head, flow rate and pump efficiency will be reduced. The effect of high density on centrifugal pump performance A high density liquid only affects the power consumption of a centrifugal pump. The head, flow rate and pump efficiency will remain unchanged. The power consumption will increase at a ratio corresponding to the increase in density. A liquid with a specific gravity of 1.2 will thus require a 2% larger power input. An oversize motor will often be required. WinCAPS can help you select the right pump for liquids with viscosity/density different from those of water. TM

27 Operating conditions NBG, NBGE, NKG, NKGE Liquid temperatures The NBG and NKG pump range covers the temperature range from 25 C to +14 C. The permissible liquid temperature depends on the mechanical shaft seal type and pump type. See also the table below. Be aware that the maximum liquid temperature limits stated by Grundfos may be overruled by local regulations and various laws. The maximum liquid temperature is stamped on the nameplate.

If the water contains oil or if chemicals or other liquids than water are pumped, you may have to replace the rubber parts of the mechanical shaft seal. FKM Mechanical shaft seals with FKM (xxxv) rubber have excellent resistance against oil and a number of chemicals. Carbon/silicon carbide Mechanical shaft seals with carbon/silicon carbide (xaqx) seal faces have a wide range of applications and are especially suitable if there is risk of dry running and/or if the temperature is high. These mechanical shaft seals are not suitable for liquids containing abrasive particles as the carbon parts will be worn. At temperatures below C, corrosion inhibitors containing abrasive particles will usually be added to the pumped liquid, and xaqx seals will thus not be suitable. Silicon carbide/silicon carbide Mechanical shaft seals with silicon carbide/silicon carbide (xqqx) seal faces also have a very wide range of applications. These seals are very resistant to abrasive particles and well suited at liquid temperatures up to +9 C. At higher temperatures, the reduced lubricating properties of the pumped liquid may cause noise problems and limit the life of the seal faces. 27

28 Operating conditions NBG, NBGE, NKG, NKGE Pump speed relative to impeller material and size The below table shows the relationship between pump speed, impeller material and size. Ø 65 [mm] CuSn EN-GJL min -1 TM Fig. 17 Maximum permissible speed For stainless steel impellers (1.448/1.4517) the limit is 36 min -1 regardless of impeller size. Inlet pressure Maximum inlet pressure The actual inlet pressure + pressure when the pump is running against a closed valve must always be lower than the maximum permissible operating pressure. Minimum inlet pressure The minimum inlet pressure must be according to the curve + a safety margin of at least.5 m + correction for vapour pressure. It is, however, advisable to calculate the inlet pressure if: the liquid temperature is high the flow rate is considerably higher than the pump's rated flow rate the pump is operating in an open system with suction lift the liquid is sucked through long pipes the inlet conditions are poor the operating pressure is low. 28

29 Operating conditions NBG, NBGE, NKG, NKGE Calculation of maximum suction lift for water in open systems To avoid cavitation, make sure that there is a minimum pressure on the suction side of the pump. The maximum suction lift "H" in metres head can be calculated as follows: H = p b x 1.2 H f H v H s Hf 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. = Net Positive Suction Head in metres head. (To be read from the curve at the highest flow the pump will be delivering.) H f = Friction loss in suction pipe in metres head. (At the highest flow the pump will be delivering.) H v = Vapour pressure in metres head. (To be read from the vapour pressure scale. "H v " depends on the liquid temperature "T m ".) H s = Safety margin = minimum.5 metres head. If the "H" calculated is positive, the pump can operate at a suction lift of maximum "H" metres head. If the "H" calculated is negative, an inlet pressure of minimum "H" metres head is required.

30 Installation and operating NBG, NBGE, NKG, NKGE Foundation (NKG) We recommend that you install the pump on a plane and rigid concrete foundation which is heavy enough to provide permanent support for the entire pump. The foundation must be capable of absorbing any vibration, normal strain or shock. As a rule of thumb, the weight of the concrete foundation should be 1.5 times the pump weight. Base frame prepared for grouting is available as an option, see Fig. 23. The foundation should be 1 mm larger than the base frame on all four sides, see Fig. 2. TM Fig. 21 Correct foundation Fig. 22 Incorrect foundation TM TM Fig. 2 Foundation The minimum height of the foundation (h f ) can then be calculated: m h pump 1.5 f = L f B f δ concrete The density (δ) of concrete is usually taken as 22 kg/ m³. Place the pump on the foundation and fasten it. The base frame must be supported under its entire area, see Fig. 21. Fig. 23 Base frame prepared for grouting Piping When 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. 24 TM

31 Installation and operating NBG, NBGE, NKG, NKGE Expansion joint Fig. 24 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 as this will cause damage to the pump. Fig. 25 Pipeline mounting Elimination of noise and vibrations In order to achieve optimum operation and minimum noise and vibration, consider vibration dampening of the pump. Generally, always consider this for pumps with motors above 11 kw. Smaller motor sizes, however, may also cause undesirable noise and vibration. Noise and vibration are generated by the revolutions of the motor and pump and by the flow in pipes and fittings. The effect on the environment is subjective and depends on correct installation and the state of the remaining system. Elimination of noise and vibrations is best achieved by means of vibration dampers and expansion joints. TM TM Vibration damper Fig. 26 NKG pump with expansion joints and vibration dampers Vibration dampers To prevent the transmission of vibrations to buildings, we recommend you to isolate the pump foundation from building parts by means of vibration dampers. The selection of the right vibration damper requires the following data: forces transmitted through the damper motor speed considering speed control, if any required dampening in % (suggested value is 7%). Which is the right damper varies from installation to installation, and a wrong damper may increase the vibration level. Vibration dampers should therefore be sized by the supplier. Expansion joints If you install the pump on a foundation with vibration dampers, always fit expansion joints on the pump flanges. This is important to prevent the pump from "hanging" in the flanges. Install expansion joints to absorb expansions/contractions in the pipework caused by changing liquid temperature reduce mechanical strains in connection with pressure surges in the pipework isolate mechanical structure-borne noise in the pipework (only rubber bellows expansion joints). Note: Do not install expansion joints to compensate for inaccuracies in the pipework such as centre displacement of flanges. Fit expansion joints at a distance of minimum 1 to 1½ times the nominal flange diameter away from the pump on the suction as well as on the discharge side. This will prevent the development of turbulence in the expansion joints, resulting in better suction conditions and a minimum pressure loss on the pressure side. At high water velocities (> 5 m/s) we recommend you to install larger expansion joints corresponding to the pipework. TM

32 Installation and operating NBG, NBGE, NKG, NKGE We always recommend expansion joints with limiting rods for flanges larger than DN 1. Alignment (NKG) In 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. 32

33 Speed-controlled pumps NBG, NBGE, NKG, NKGE Most NBG and NKG pumps are available with motors with integrated speed control. These pumps are called NBGE and NKGE. Alternatively, all NBG and NKG pumps with threephase motors can be connected to an external frequency converter. NBGE and NKGE pump applications NBGE and NKGE pumps with integrated speed control enable automatic adaptation of performance to current conditions. This keeps the energy consumption at a minimum. Depending on the nature of the application, NBGE and NKGE pumps offer energy-savings, increased comfort or improved processing. The charts below show possible control modes of NBGE and NKGE pumps in different applications. Control mode Constant curve Constant pressure Temperature control Constant flow Applications Single-pipe heating systems Systems with three-way valves Heating and cooling surfaces Chiller pumps (Sensor not required) Pressure boosting systems (Sensor required) Single-pipe heating systems Systems with three-way valves Cooling towers Chiller pumps Domestic hot-water recirculation systems (Sensor required) Heating and cooling surfaces Cooling towers Flow filters (Sensor required) Proportional differential pressure (measured) System with two-way valves (Differential pressure sensor is located in the system) Constant curve In constant curve control mode, the pump will adjust its speed to meet the required flow without using throttle valves. In this control mode the pump can be set to operate within 12-1% of the maximum performance range. A sensor is not required for this control mode. Constant pressure In constant pressure-control mode, the pump will adjust its speed to keep a constant pressure where the sensor is fitted. We recommend constant-pressure control mode in pressure-holding systems. A pressure sensor with a suitable operating range is required. Temperature control In the temperature control mode, the pump will adjust its speed to keep a constant temperature or a differential temperature. We recommend this control mode in systems with three-way valves and systems without control valves. A temperature sensor or a differential temperature sensor is required for this control mode. Example In an industrial cooling system, an NKGE pump continuously adapts its performance to the changing demands reflected in the differences in temperature of the liquid circulating in the cooling system. The lower the demand for cooling, the smaller the quantity of liquid circulated in the system and vice versa. Constant flow In the constant-flow control mode, the pump will adjust its speed to keep a constant flow irrespective of variations of the system characteristics. We recommend this control mode in systems where a constant flow is required. In this control mode either an electronic flowmeter or a differential pressure sensor is required. Proportional differential pressure (measured) In the proportional differential pressure (measured) mode, the pump will adjust its speed to keep the differential pressure in a reference point in the system. This control mode is recommended in large circulation systems where the NBGE or NKGE pump functions as a secondary pump. A differential pressure sensor is required for this control mode. 33

34 Speed-controlled pumps NBG, NBGE, NKG, NKGE Example In a two-pipe heating system or an air-conditioning system with variable flow, the pressure sensor can be fitted in a reference point away from the NKGE pump. Finally, it is worth noting that the efficiencies of the frequency converter and the motor must be taken into account if a precise calculation of the power saving resulting from a reduction of the pump speed is wanted. As the flow increases, the NKGE pump continuously adapts its speed to maintain the same differential pressure in the reference point. Affinity equations Normally, NBGE and NKGE pumps are used in applications characterised by a variable flow. Consequently, it is not possible to select a pump that is constantly operating at its optimum efficiency. In order to achieve optimum operating economy, the pump should be selected on the basis of the following criteria: H H n H x Eta Q x n n n x Q n Q Q n n n = Q x n x H n n n = H x n x The max. duty point required should be as close as possible to the QH 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, NBGE and NKGE pumps have an infinite number of performance curves each representing a specific speed. It may therefore not be possible to select a duty point close to the max. curve. H Max. curve P P n Q x Q n Px Fig. 28 Affinity equations Q Q η n η x P n n n = P x n x TM Min. curve Q [m³/h] Fig. 27 Min. and max. performance curves In situations where it is not possible to select a duty point close to the max. curve, use the affinity equations below. The head (H), the flow (Q) and the input power (P) are the appropriate variables you need to be able to calculate the motor speed (n). Note: The approximated formulas apply on condition that the system characteristic remains unchanged for nn and nx and that it is based on the formula H = k x Q2, 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.

35 Communication NBG, NBGE, NKG, NKGE Communication with NBGE/NKGE pumps Communication with NBGE, NKGE pumps is possible via a central building management system, remote control (Grundfos R1) or a control panel. Central building management system The operator can communicate with the NBGE, NKGE pump even though he is not present near the pump. Communication can take place via a central building management system allowing the operator to monitor and change control modes and setpoint settings. LON-bus connection Remote control The R1 remote control produced by Grundfos is available as an accessory. The operator can communicate with the NBGE, NKGE pump by pointing the IR-signal transmitter at the control panel of the NBGE, NKGE pump terminal box.

36 Selection of product NBG, NBGE, NKG, NKGE Pump size Selection of pump size should be based on: required flow rate and pressure at the draw-off point pressure loss as a result of height differences friction loss in the pipework. 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. Efficiency If you expect the pump to always operate in the same duty point, select a pump which is operating in a duty point corresponding to the best efficiency of the pump. In case of controlled operation or varying consumption, select a pump whose best efficiency falls within the duty range covering the greater part of the duty time. Material The material variant should be selected on the basis of the liquid to be pumped, see "List of pumped liquids", page 37. Motor size Selection of motor size should be based on the power required to achieve the duty point of the chosen pump. This information can be found in the power chart below each performance chart. See performance curves on page 5 to page 234. Find the power curve corresponding to the required QH-value (or interpolate between curves). To select the motor size, read the value of the P2 curve at the duty point and add a 5% safety margin. If the motor size must be selected according to ISO 5199, see the table below. Safety margins according to ISO 5199 Required pump power up to [kw] Motor power P 2 [kw]

37 Pumped liquids NBG, NBGE, NKG, NKGE Pumped liquids We recommend NBG and NKG pumps for thin, clean and non-explosive liquids, not containing solid particles or fibres. The liquid must not attack the pump materials chemically or mechanically. If you pump liquids with a density and/or viscosity higher than those of water, use motors with correspondingly higher outputs. See "List of pumped liquids". The mechanical shaft seal must be suitable for the liquid. Water in heating and ventilating systems often contains additives to prevent negative effects, such as system corrosion or calcareous deposits. If you want to use the pump for such liquids, and if the temperature is above 8 C, use special shaft seals to avoid crystallization/ precipitation between the seal faces. Liquid temperature: 25 C to +14 C. For heating systems, the water quality should meet VDI 235. List of pumped liquids The list on the following pages gives an overview of liquids which may typically be pumped by NBG and NKG pumps. The list states the recommended shaft seals. Other shaft seals may be applicable, but we consider those stated in the list to be the best choices. The list is intended as a general guide only, and it cannot replace actual testing of pumped liquids and pump materials under specific working conditions. However, use the list with some caution, as factors may affect the chemical resistance of a specific pump version. The factors are operating conditions solids cleaning procedures contaminants pressure. Legend for notes in the list a b c d e f g To minimize the risk of corrosion, the pump must run continuously, i.e. standstills must not exceed 6-8 hours. May contain additives or impurities which can cause shaft seal problems. The pump should run continuously to prevent discoloration of pool tiles. For intermittent use, the N version should be used. Density and viscosity may differ from those of water. Consider this when calculating motor and pump performance. In order to avoid corrosion, the liquid must be free of oxygen. Flammable or combustible liquid. Risk of crystallization/precipitation at the shaft seal. 37

48 Curve charts and technical data NBG, NBGE, NKG, NKGE Curve conditions The guidelines below apply to the curves shown in the performance charts on page 5 to 235. Tolerances according to ISO 996, Annex A. The curves show pump performance with different impeller diameters at the nominal speed. The bold part of the curves show the recommended operating range. The thin parts are not recommended as the possible operating range here might suggest the selection of a smaller/larger pump type. Do not use the pumps at minimum flow rates below.1 x Q max because of the danger of overheating the pump. The curves apply to the pumping of water at a temperature of +2 C and a kinematic viscosity of 1mm 2 /s (1 cst). Eta: The dashed lines show values of the hydraulic efficiency of the pump. : The curves show average values measured under the same conditions as the performance curves. When sizing the pump, add a safety margin of at least.5 m. In case of other densities than 1 kg/m 3, the discharge pressure is proportional to the density. When pumping liquids with a density higher than 1 kg/m 3, 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. Performance tests The requested duty point for every pump is tested according to ISO 996, Annex A, and without certification. If the customer requires either more points on the curve to be checked or certain minimum performances or certificates, individual measurements must be made. Certificates Certificates have to be confirmed for every order and are available on request as follows: Certificate for compliance with the order EN Pump certificate EN Inspection certificate EN B Inspection certificate EN C. Technical data The pump dimensions on the following pages include NBG/NKG: Data based on the NBG/NKG premium range. That is pumps fitted with Grundfos MG (EFF or Siemens (EFF motors. Note: See the correction tables on page 249 and 253 for dimensions of pumps with MMG model E, TECO EFF1 and TECO EFF2 motors. NBGE/NKGE: Data on pumps fitted with motors with built-in frequenct converter, type MGE/MMGE. H total = H geo + H stat + H dyn H geo : H stat : H dyn : Height difference between measuring points. Differential head between the suction and discharge side of the pump. Calculated values based on the velocity of the pumped liquid on the suction and discharge side of the pump. 48
