4 Product data MTR(E), MT, MTA Introduction This data booklet deals with MTR, MTRE, MT and MTA pumps. MTRE - pumps with built-in frequency-converter Fig. 1 MTR, MT and MTA pumps MTR, MT, MTA pumps are vertical multistage centrifugal pumps designed for pumping of cooling lubricants for machine tools, condensate transfer and similar applications. The pumps are designed to be mounted on top of tanks with the pump stack immerged in the pumped liquid. Grundfos MTR, MT and MTA pumps come with various pump sizes and various 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 MG motor designed to EN standards. The pump unit consists of optimised hydraulics, various types of connections, a motor stool, a given number of chambers and various other parts. TM Fig. 2 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 frequency control. The motor of the MTRE pump is a Grundfos MGE motor designed to EN standards. Frequency control enables continuously variable control of motor speed, which makes it possible to set the pump to operation in any duty point. 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 frequency-controlled speed control offers obvious advantages: Energy savings Increased comfort Control and monitoring of the pump performance. TM

9 Product data MTR(E), MT, MTA Applications Application MTR(E) MT MTA Lathes - - Spark machine tools - Grinding machines Swarf conveyors - - Machining centres Cooling units Industrial washing machines Filtering systems The pump is suitable for this application. 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 flow 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 cost-efficient operation as a result of a stable production. Constant pressure Washing systems etc. Example: Within industrial washing systems, MTRE pumps with integrated 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 with 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. 9

16 Product data MTR(E), MT, MTA Viscosity MTR 1s, 1, 3, 5 can pump up to 5 cst. MTR 1, 15, 2, 32, 45, 64 can pump up to 1 cst. 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. The following examples show the drop in the hydraulic performance of MTR(E) pumps pumping oil with a density of 872 kg/m 3 but with three different kinematic viscosities.

19 Product data MTR(E), MT, MTA Calculation of the reduced head of a pump with empty chambers Calculation of pressure loss in empty chambers From the above curves and the curve charts of each pump type starting on page 38, it is possible to calculate the reduced head of a pump with empty chambers. The calculation can be made as shown below. Example: Pump type MTR 5-18/7 Flow Q (duty point) 6 [m 3 /h] ead (duty point) 9 The selected pump is an MTR 5-18/18 with 11 empty chambers, see type keys on page 33. From the above pressure loss curve of MTR 5, it appears that the pressure loss of each empty chamber at 6 m 3 /h is.14. This results in a total pressure loss of: Total pressure loss = = 1.54 Calculation of pressure loss in chambers with impeller MTR 5-18/7 has a flow of 6 m 3 /h through the pump and a constant (k) of.11. Δ = Δ = By adding the two pressure losses you get the following total pressure loss through the idle pump: Δ total = Δ empty chambers + Δ chambers with impeller Δ total = Δ total = The reduced head of the MTR 5-18/7 pump including pressure losses caused by empty chambers is: ead = = The head 33 metres is read from the performance curve for an MTR 5-18/7, see page 42. Pressure loss in chambers with impeller The pressure loss in chambers with impeller can be calculated by means of the following formula: Δ = k Q 2 n Key: Factor Δ k Q n Description Difference in head A constant Flow through the pump [m 3 /h] Number of stages with impellers 19

20 Control of MTRE pumps MTR(E), MT, MTA Control options for MTRE pumps Communication with MTRE pumps is possible by means of a control panel, remote control (Grundfos R1), external digital or analoge control signals, an RS485 bus interface. The purpose of controlling a MTRE pump is to monitor and control the pressure, temperature, flow or liquid level of the system. Control panel The control panel of the MTRE pump terminal box makes it possible to change the setpoint settings manually. 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 Light fields LON connection LON interface Fig. 11 Control panel on MTRE pump Remote control Indicator lights Buttons The R1 remote control produced by Grundfos is available as an accessory. The operator communicates with the MTRE pump by pointing the IR-signal transmitter at the control panel of the MTRE pump terminal box.

21 Control of MTRE pumps MTR(E), MT, MTA Control modes of MTRE pumps MTRE pumps can be connected to an external sensor enabling control of pressure, differential pressure, temperature, 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.

Is the pump expected always to operate at the same duty point, select an MTR, MT, MTA pump which is operating at a duty point corresponding to the best efficiency of the pump. p [kpa] P2 [kw] MTR, MTRE 32 5 z ISO 996 Annex A Q [l/min] Q [m³/h] P2 1/1 P2 2/3 [%] Dutypoint Best efficiency Q [l/min] Q [l/min] NPS 8 NPS Q [l/min] TM Q [m³/h] P2 [kw] P2 1/1 P2 2/ Q [l/min] NPS 8 NPS Q [l/min] [%] TM Fig. 3 Example of an MTR pump s duty point As the pump is sized on the basis of the highest possible flow, it is important always to have the duty point to the right on the efficiency curve (eta) in order to keep efficiency high when the flow drops. eta Fig. 29 Example of a curve chart 2. Dimensional data When sizing a pump the following must be taken into account: Required flow rate and pressure at the draw-off point. Pressure loss as a result of height differences ( geo ). Friction loss in the pipework ( f ). 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. NPS value.

39 Selection and sizing MTR(E), MT, MTA 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 2 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. Max. curve 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. n x Q x n x Q n n n Q Q n n n = Q n x x n n n = n x x η n η x Min. curve Q [m³/h] Fig. 33 Min. and max. performance curves In situations where it is not possible to select a duty point close to the max. curve, the affinity equations below can be used. 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 2 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 programmes make it possible to calculate an MTRE 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 comsumption. For further information see page 124 and page

40 Selection and sizing MTR(E), MT, MTA Minimum inlet pressure - NPS Calculation of the inlet pressure "" is recommended when... the liquid temperature is high, the flow is significantly higher than the flow rate, 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 1.2 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 rate the pump will be delivering). f = Friction loss in suction pipe in metres head. (At the highest flow rate the pump will be delivering.) v = Vapour pressure in metres head. s = Safety margin = minimum.5 metre 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 Q Fig. 35 Minimum inlet pressure - NPS Note: In order to avoid cavitation, never select a pump whose duty point is too far to the right on the NPS curve.

117 Pumped liquids MTR(E), MT, MTA Pumped liquids MTR(E), MT and MTA 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 MTR(E) 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] Free strainer passage [cm 2 ] Impeller passage [mm] MTR(E) 1s MTR(E) MTR(E) MTR(E) MTR(E) MTR(E) MTR(E) MTR(E) MTR(E) MTR(E) 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 2 ppm. 117

118 Pumped liquids MTR(E), MT, MTA 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 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. Notes D Often with additives. Density and/or viscosity differ from that of water. E Allow for this when calculating motor output and pump performance. Pump selection depends on many factors. F Contact Grundfos. Risk of chrystallization/precipitation in shaft seal. 1 The pumped liquid is easily ignited. 2 The pumped liquid highly inflammable. 3 Insoluble in water. 4 Low self-ignition point.
