Constant level control Condensate systems etc. Example: In a condensate system, it is important to monitor and control pump operation to maintain a constant level of condensate in the system. An MTRE pump connected to a level sensor mounted in the condensate tank makes it possible to maintain a constant liquid level. A constant liquid level ensures optimum and costefficient operation as a result of a stable production. Examples of MTRE applications An MTRE pump is the ideal solution in a number of applications characterized by a need for variable flow at constant pressure. Depending on the nature of the application, the pump offers energy-savings, increased comfort or improved processing. MTRE 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. Some of the applications in which MTRE pumps are used are mentioned below. Constant pressure Washing systems etc. Example: Within industrial washing systems, MTRE pumps connected to a pressure sensor ensure a constant pressure in the pipework. From the sensor, the MTRE pump receives input about changes of pressure resulting from changes in the consumption. The MTRE pump responds to this input by adjusting the speed and thus the pressure. The constant pressure is stabilized once more on the basis of a preset setpoint. Constant temperature Industrial cooling systems etc. Example: In industrial cooling systems, MTRE pumps connected to a temperature sensor will ensure a constant temperature and lower operating costs compared to pumps without speed control. An MTRE pump continuously adapts its performance to the changing demands reflected in the differences in temperature of the liquid circulating in the cooling system. Thus the lower the demand for cooling, the smaller the quantity of liquid circulated in the system and vice versa. Pumped liquids pumps are designed to pump non-explosive liquids that do not chemically attack the pump materials. When pumping liquids with a density and/or viscosity higher than that of water, oversized motors may be 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 may attack or dissolve the protective oxide film of the stainless steel and thus cause corrosion. Pumping of solid particles pumps are fitted with a suction strainer. The strainer prevents large solid particles from entering and damaging the pump. The table below describes the size of the passage in the strainer and the impeller. Pump type Strainer passage [ø in.] Free strainer passage [in ] Impeller passage [in.] 1s

4 1, MTC, MTA If the pumped liquid contains solid particles larger than the size of the holes in the strainer, the passage of the strainer may be blocked. In such situations the performance will drop as a result of a reduced flow through the pump. Note: If the strainer is removed from the suction port, solid particles may enter the pump and cause a seizure or even damage the pump. In grinding applications Grundfos recommends that the pumped liquid is screened for abrasive particles before entering the pump. When pumped, abrasive particles reduce the life of the pump components. Wear of the pump components caused by abrasive particles starts when the concentration exceeds ppm. List of pumped liquids A number of typical liquids are listed in the following table. 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 it cannot replace actual testing of the pumped liquids and pump materials under specific working conditions. The list should, however, be applied with some caution as factors such as concentration of the pumped liquid, liquid temperature or pressure may affect the chemical resistance of a specific pump version. Safety precautions must be made when pumping dangerous liquids.

6 1, MTC, MTA product introduction MTRE (Pumps with built-in variable frequency drive) Fig. 1 Grundfos MTR pumps pumps are vertical multistage centrifugal pumps designed for pumping of cooling lubricants for machine tools, condensate transfer and similar applications. The pumps can be used for applications involving spark machine tools, grinding machines, machine centers, cooling units, industrial washing machines, filtering systems etc. The pumps are designed to be mounted on top of tanks with the pump stack immerged in the pumped liquid. Grundfos pumps come with various pump sizes and numbers of stages to provide the flow, the pressure and the length required. The pumps consist of two main components: The motor and the pump unit. The motor is a Grundfos standard ML motor or Grundfos specified motor designed to NEMA standards. The pump unit consists of optimized hydraulics, a variety of connections, a motor stool, a given number of chambers and various other parts. TM Fig. Grundfos MTRE pumps MTRE pumps are built on the basis of MTR pumps. The difference between the MTR and the MTRE pump range is the motor. MTRE pumps are fitted with an E-motor, i.e. a motor with built-in variable frequency drive (VFD). The motor of the MTRE pump is a Grundfos MLE motor designed to NEMA standards. Frequency control enables continuously variable control of motor speed, which makes it possible for the motor to adjust to varying conditions and save energy in the process. Continuously variable control of the motor speed enables adjustment of the performance to a given requirement. The pump materials are the same as those of the MTR pump range. Why select a MTRE pump? Select a MTRE pump if controlled operation is required, i.e. consumption fluctuates; constant pressure is required communication with the pump is required. Adaptation of performance through frequencycontrolled speed control offers obvious advantages: Energy savings Increased comfort Control and monitoring of the pump performance. TM

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.

An empty chamber is a chamber without an impeller Fig Fig. 8 [ft] Q [US GPM] Q [m³/h] Pressure losses of pumped liquid passing through an empty chamber for MTR 1s and MTR 1 pumps [ft] MTR 3 MTR1S MTR 5 MTR 6 z MTR 1 MTR 6 z Q [US GPM] Q [m³/h] Pressure losses of pumped liquid passing through an empty chamber for MTR 3 and MTR 5 pumps TM TM [ft] Fig. 9 Pressure losses of pumped liquid passing through an empty chamber for MTR 1, MTR 15 and MTR pumps As 3, 5 and 6 pumps have holes in the guide vanes, no pressure losses occur in the empty chambers of these pumps. Calculation of the reduced head of a pump with empty chambers Calculation of pressure loss in empty chambers From the pressure loss curves and the pump performance curves, it is possible to calculate the reduced head of a pump with empty chambers. The calculation can be made as shown below. Example: MTR 1 MTR Q [US GPM] Q [m³/h] Pump type MTR 5-18/7 Flow Q (duty point) 5 [gpm] ead (duty point) 18 [ft] The selected pump is an MTR 5-18/7 with 11 empty chambers. From the above pressure loss curve of MTR 5, it appears that the pressure loss of each empty chamber at 5 [gpm] is.6 [ft]. This results in a total pressure loss of: Total pressure loss =.6 11 = 5 [ft] MTR 6 z The reduced head of the MTR 5-18/7 pump including pressure losses caused by empty chambers is: ead = = 18 [ft] MTR TM 8581 The head 185 ft is read from the performance curve for an MTR

18 1, MTC, MTA Control of MTRE pumps Control options for MTRE pumps Communication with MTRE pumps is possible by means of a control panel, remote control (Grundfos R1), external digital or analog control signals, an RS85 bus interface. The purpose of controlling a MTRE pump is to monitor and control the pressure, temperature, flow or liquid level of the system. External control signals Communication with the MTRE pump is possible even though the operator is not present near the MTRE pump. Communication is enabled by connecting the MTRE pump to an external control or monitoring system allowing the operator to monitor and change control modes and setpoint settings of the MTRE pump. Central management system Control panel The control panel of the MTRE pump terminal box makes it possible to change the setpoint settings manually. Light fields LON connection LON interface Indicator lights Fig. 1 Control panel on MTRE pump Remote control The R1 remote control produced by Grundfos is available as an accessory. See page 57. The operator communicates with the MTRE pump by pointing the IR-signal transmitter at the control panel of the MTRE pump terminal box.

TM 76 TM 98 8 GENIbus connection MTRE pump Fig. 1 Example of a central management system with LON interface Control modes of MTRE pumps MTRE pumps can be connected to an external sensor enabling control of pressure, differential pressure, temperature, level, differential temperature or flow. MTRE pumps can be set to two control modes controlled or uncontrolled operation. In controlled operating mode the pump is automatically operating according to the desired setpoint of the control parameter. The illustration below shows a pump with flow control as an example of controlled operation. In uncontrolled operating mode the pump operates according to the constant curve set. TM

22 1, MTC, MTA Required flow rate, required pressure 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. f Fig. Dimensional data geo Normally, MTRE pumps are used in applications characterized by a variable flow rate. Consequently, it is not possible to select a pump that is operating constantly at optimum efficiency. In order to achieve optimum operating economy, the pump should be selected on the basis of the following criteria: The maximum duty point should be as close as possible to the Q curve of the pump. The required duty point should be positioned so that P is close to the max. point of the Q curve. Between the minimum and maximum performance curves, MTRE 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 max. curve.

The head (), the flow rate (Q) and the input power (P) are all 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 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.

The two programs make it possible to calculate an pump s specific duty point and energy consumption. By entering the sizing data of the pump, WinCAPS and WebCAPS can calculate the exact duty point and energy consumption. For further information see page 16 and page 17.

23 , MTC, MTA 1 Minimum inlet pressure - NPSR Calculation of the inlet pressure "" is recommended when... the liquid temperature is high, the flow is significantly higher than the rated flow, 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 feet of head can be calculated as follows: = p b NPSR f v s p b = Barometric pressure in feet absolute. (Barometric pressure can be set to 33.9 feet). In closed systems, p b indicates the system pressure in feet. NPSR = Net Positive Suction ead in feet of head. (To be read from the NPSR curve at the highest flow rate the pump will be delivering). f v = Friction loss in suction pipe in feet of head. (At the highest flow rate the pump will be delivering.) = Vapor pressure in feet. (To be read from the vapor pressure scale. " v " depends on the liquid temperature "T m "). s = Safety margin = minimum. feet. If the "" calculated is positive, the pump can operate at a suction lift of maximum "" feet of head. If the "" calculated is negative, an inlet pressure of minimum "" feet of head is required. f P b Fig. 7 Minimum inlet pressure - NPSR tm ( F) v (Ft) Note: In order to avoid cavitation, never select a pump whose duty point is too far to the right on the NPSR curve. Always check the NPSR value of the pump at the highest possible flow rate. Q v TM

TM Fig. 8 Example of an MTR, MTRE curve chart Guidelines to performance curves The guidelines below apply to the curves shown on the following pages: 1. Tolerances to ISO 996, Annex A, if indicated.. The motors used for the measurements are standard Grundfos motors (ML or MLE). 3. Measurements have been made with airless water at a temperature of +68 F (+ C).. The curves apply to a kinematic viscosity of υ =1mm /s (1 cst). 5. Due to the risk of overheating, the pumps should not be used at a flow below the minimum flow rate. 6. Q curves of the individual pumps are based on current motor speeds. The curve below shows the minimum flow rate as a percentage of the nominal flow rate in relation to the liquid temperature. Only pumps with EPDM elastomers in the shaft seals can run in the temperature range from +19 F to +8 F (+9 C to +1 C). Closed strap nuts with o-rings and plugging of the shaft seal drain hole, may also be required at temperatures above +1 F (+1 C) (see page ).

58 1, MTC, MTA MP motor protector Fig. 3 MP The MP is an electronic motor protector and data collecting unit. Apart from protecting the motor, it can also send information to a control unit via GENIbus, like for instance: trip warning energy consumption input power motor temperature. The MP protects the motor primarily by measuring the motor current by means of a true RMS measurement. The pump is protected secondarily by measuring the temperature with a Tempcon sensor, a Pt1/Pt1 sensor and a PTC sensor/thermal switch. The MP is designed for single- and three-phase motors. Note: The MP must not be used together with frequency converters. TM MP features Phase-sequence monitoring indication of current or temperature input for PTC sensor/thermal switch indication of temperature in F or C -digit, 7-segment display setting and status reading with the Grundfos R1 remote control setting and status reading via the Grundfos GENIbus fieldbus.

59 , MTC, MTA. MTC MTC MTC product introduction MTC pumps are vertical multistage centrifugal pumps designed for pumping of cooling lubricants for machine tools, condensate transfer and similar applications. When pumping liquids with a density and/or viscosity higher than that of water, oversized motors may be 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 may attack or dissolve the protective oxide film of the stainless steel and thus cause corrosion. Fig. 33 Grundfos MTC pumps TM 85 Pumping of solid particles MTC pumps are fitted with a suction strainer. The strainer prevents large solid particles from entering and damaging the pump. The table below describes the size of the passage in the strainer and the impeller. The pumps can be used for applications involving spark machine tools, grinding machines, machine centers, cooling units, industrial washing machines, filtering systems etc. The pumps are designed to be mounted on top of tanks with the pump stack immerged in the pumped liquid. Grundfos MTC pumps come with various pump sizes and numbers of stages to provide the flow, the pressure and the length required. The pumps consist of two main components: The motor and the pump unit. The motor is a Grundfos standard ML motor or Grundfos specified motor designed to NEMA standards. The pump unit consists of optimized hydraulics, a variety of connections, a motor stool, a given number of chambers and various other parts. MTC applications Application MTC Lathes Spark machine tools (EDM) - Grinding machines Swarf conveyors Machining centers Cooling units Industrial washing machines Filtering systems The pump is suitable for this application. Pumped liquids MTC pumps are designed to pump non-explosive liquids that do not chemically attack the pump materials. Pump type If the pumped liquid contains solid particles larger than the size of the holes in the strainer, the passage of the strainer may be blocked. In such situations the performance will drop as a result of a reduced flow through the pump. Note: If the strainer is removed from the suction port, solid particles may enter the pump and cause a seizure or even damage the pump. In grinding applications Grundfos recommends that the pumped liquid is screened for abrasive particles before entering the pump. When pumped, abrasive particles reduce the life of the pump components. Wear of the pump components caused by abrasive particles starts when the concentration exceeds ppm. MTC features and benefits MTC pumps MTC pumps are fitted with an integrated Grundfos motor where the rotor shaft is used as pump shaft. This gives the pump a compact design. Motors for MTC pumps MTC motors are totally enclosed, fan-cooled, -pole Grundfos standard motors. Electrical data Strainer passage [ø in.] Free strainer passage [in ] Impeller passage [in.] MTC MTC

Further product documentation WebCAPS Selection program available on WebCAPS contains detailed information on more than, Grundfos products in more than languages. In WebCAPS, all information is divided into 6 sections: Catalog Literature Service Sizing Replacement CAD drawings. WebCAPS is a Web-based Computer Aided Product Catalog With a starting point in areas of applications and pump types, this section contains technical data curves (Q, Eta, P1, P, etc) which can be adapted to the 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 In this section you can access all the latest documents of a given pump, such as product guides Installation and operating instructions service documentation, such as Service kit catalog and Service kit instructions quick guides product brochures, etc. Service This section contains an easy-to-use interactive service catalog. ere you can find and identify service parts of both existing and cancelled Grundfos pumps. Furthermore, this section contains service videos showing you how to replace service parts. 16

107 1, MTC, MTA Sizing With a starting point in different application areas and installation examples, this section gives easy step-by-step instructions in how to 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. analyze your selected pump via the built-in life cycle cost tool determine the flow velocity in wastewater applications, etc. Replacement Further product documentation In this section you find a guide to select and compare 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. After having specified the installed pump, the guide suggests a number of Grundfos pumps which can improve both comfort and efficiency. CAD drawings In this section it is possible to download -dimensional (D) and 3-dimensional (3D) CAD drawings of most Grundfos pumps. The following formats are available in WebCAPS: -dimensional drawings.dxf, wireframe drawings.dwg, wireframe drawings. 3-dimensional drawings.dwg, wireframe drawings (without surfaces).stp, solid drawings (with surfaces).eprt, E-drawings.
