Through the Directives /3/EC, energy-using products (EuP), and 9/1/EC, energy-related products (ErP) a framework for ecodesign requirements was established. The Commission Regulations (EC) No 6/9 and (EU) No /1 have implemented two directives with regard to ecodesign requirements for three-phase Hz electric motors placed on the market and put into service inside EU zone as self-alone units or integrated in other products. This regulation states that motors must have efficiency level IE3 (or IE + Variable Speed Drive) from 1 st January 1 for 7, to 37 kw rated powers and from 1 st January 17 for,7 to 37 kw ones. The Commission Regulation (EU) No 7/1 has implemented two directives with regard to ecodesign requirements for some types of clean water pumps placed on the market and put into service inside EU zone as self-alone units or integrated in other products. This regulation states that water pumps shall have index MEI. as minimum from 1 st January 1. That index comes from a dedicated formula which considers hydraulic efficiency values at best efficiency point (BEP), 7 % of the flow at BEP (Part load PL) and 11 % of the flow at BEP (Over load OL). The Lowara e-lnt series, for the models in the scope of the regulations above, is ErP compliant, having an index MEI equal or higher than, and IE3 motor efficiency.

5 e-lnt SERIES GENERAL INTRODUCTION The new Lowara e-lnt Series is the result of the close collaboration between our customers and us; the new range has been redesigned and improved to meet the Commercial Building Services (CBS) requirements, in terms of performances and energy saving. In addition the new Lowara e-lnt Series can be customized to meet the needs of the Industry, keeping the bestin-class quality in production that affords our pumps continuous reliability and robustness in operation. Pump design The new Lowara e-lnt Series is a dual volute centrifugal pump with in-line suction and delivery flanges; both volutes are fitted with closed impellers linked by an automatic changeover valve. The two pumps can operate separately or in parallel. The e-lnt Series has a Back pull-out design (impeller, adapter, and motor can be extracted without disconnecting the pump body from the piping system). The dual volutes provides system redundancy; and one volute can be serviced while the other remains operational. The pumps have cast iron casing as standard; the impeller standard material is cast iron but is also available in bronze and stainless steel. The pumps are equipped with interchangeable mechanical seals and IE3 efficiency motors; and are available in the following constructions: Extended shaft Close-coupled by means of an adaptor bracket with an impeller keyed directly to the special motor shaft extension. Stub shaft Rigid-coupled with a bracket, an adaptor and a rigid coupling keyed to the standard motor shaft extension. Hydraulic specifications Maximum delivery - (one pump running): 7 m 3 /h (-pole range) 39 m 3 /h (-pole range) - (two pump running): m 3 /h (-pole range) 69 m 3 /h (-pole range) Maximum head: 9 m (-pole range). m (-pole range).

21 ErP 9/1/EC e-lnt SERIES PUMPS Over last decade the European Commission with the Energy Efficiency Plan pushed the European Parliament and the Council to adopt specific measures to the purpose of reducing energy consumption and further negative environmental impacts. Through the Directives /3/EC, energy-using products (EuP), and 9/1/EC, energy-related products (ErP) a framework for ecodesign requirements was established. The Commission Regulation (EU) No 7/1 has implemented two directives with regard to ecodesign requirements for some types of clean water pumps placed on the market and put into service inside EU zone as self-alone units or integrated in other products. For end-suction close-coupled in-line pumps (ESCCi for the Regulation) the efficiency assessment refers to: just the pump and not the pump and motor assembly (electric or combustion); pumps with just one impeller; pumps with a nominal pressure PN not higher than 16 bar (16 kpa); pumps with a minimum nominal flow not less than 6 m 3 /h; pumps with a maximum nominal power at the shaft not higher than 1 kw; pumps designed to operate at a speed of 9 min- 1 (for electric pumps this means Hz -pole electric motors) and with a head not greater than 1 metres; pumps designed to operate at a speed of 1 min- 1 (for electric pumps this means Hz -pole electric motors) and with a head not greater than 9 metres; use with clean water at a temperature ranging from -1 C to 1 C (the test is performed with cold water at a temperature not higher than C). According to the definitions established in the Regulation LNTE and LNTS versions correspond to the end-suction close-coupled in-line pump. This regulation states that water pumps shall have a minimum index MEI coming from a dedicated formula which considers hydraulic efficiency values at best efficiency point (BEP), 7 % of the flow at BEP (Part load PL) and 11 % of the flow at BEP (Over load OL). The Regulation also establishes the following deadlines. from minimum efficiency index (MEI) 1 st January 13 MEI,1 1 st January 1 MEI, Regulation (EU) n. 7/1 Annex II point (Product information requirements) 1) Minimum efficiency index: see MEI values in specific tables on following page. ) The benchmark for most efficient water pumps is MEI,7. 3) Year of manufacture: 1. ) Manufacturer: Xylem Service Italia Srl - Reg. No Montecchio Maggiore, Vicenza, Italy. ) Product type: see the PUMP TYPE column in the tables in the Hydraulic performance section. 6) Hydraulic pump efficiency with trimmed impeller: see ηp and ØT columns in the tables in the Hydraulic performance section. 7) Pump performance curves, including the performance curve: see the Operating Characteristics graphs in the following pages. 8) The efficiency of a pump with a trimmed impeller is usually lower than that of a pump with the full impeller diameter. The trimming of the impeller will adapt the pump to a fixed duty point, leading to reduced energy consumption. The minimum efficiency index (MEI) is based on the full impeller diameter. 9) The operation of this water pump with variable duty points may be more efficient and economic when controlled, for example, by the use of a variable speed drive that matches the pump duty to the system. 1) Information relevant for disassembly, recycling or disposal at end-of-life: observe the current laws and by-laws governing sorted waste disposal. Consult the product operating manual. 11) Designed for use below 1 C only : note not applicable to these products. 1) Designed for use above 1 C only : note not applicable to these products. 13) Specific instructions for pumps as per points 11 and 1: not applicable to these products. 1) Information on benchmark efficiency is available at : (Ecodesign section). 1) The benchmark efficiency graphs with MEI =.7 and MEI =. are available at or (refer to ESCCi 1 rpm ). 1

97 LNT..H (e-lnt WITH HYDROVAR) 97

98 LNT..H SERIES (e-lnt WITH HYDROVAR) Background and context For all pumping needs in commercial or residential building and in industry applications, the demand for intelligent pumping systems is constantly growing. Controlled systems offer many advantages: reduced operating costs for the lifetime of the pump, lower environmental impact, longer lifetime of piping systems and networks. For this reason, Lowara has developed the LNT..H: an intelligent pumping system which assures high level performance with energy consumption tailored to the system s demand. Benefits of e-lnt with HYDROVAR Saving: LNT..H transforms the LNT pumps into variable speed intelligent pumping systems. Thanks to the HYDROVAR, the speed of each pump varies so as to maintain a constant flow, a constant pressure, or a differential pressure. In doing so, at any point in time, the pump only receives the energy required. This in turns allows for considerable savings, especially for systems that have varying loads throughout the day. Key Features of the Hydrovar No need for additional pressure sensors: The LNT..H is fitted with a pressure transmitter or differential pressure transmitters, depending on the application. No need for special pumps or motors. No need for bypass or safety systems: The LNT..H will immediately switch off when demand drops to zero or when it exceeds maximum pump capacity; thus making installation of additional safety devices unnecessary. Anti-condensation device: The LNT..H is fitted with anti-condensation devices which switch on when the pump is in standby in order to prevent condensation forming in the unit. Easy installation and space-saving: LNT..H saves time and space during installation. The Hydrovar is delivered already mounted on the motor (for models up to kw). The hydrovar is kept cool by the motor fan and does not require a control panel. In order to function, only fuses on the supply line are needed (Check your local electrical installation regulations). A wall-mounted HYDROVAR version is available for higher power outputs (up to kw). Standard motors: LNT..H models are fitted with threephase standard TEFC motors with insulation class 1 (F). 98

99 LNT..H SERIES (e-lnt WITH HYDROVAR) The basic function of the HYDROVAR device is to control the pump to meet the system demands. HYDROVAR performs these functions by: 1) Measuring the system pressure or flow via a transmitter mounted on the pump s delivery side. ) Calculating the motor speed to maintain the correct flow or pressure. 3) Sending out a signal to the pump to start the motor, increase speed, decrease speed or stop. ) In the case of multiple pump installations, HYDROVAR will automatically provide for the cyclic changeover of the pumps starting sequence. Control for constant pressure In addition to these basic functions, HYDROVAR can perform controls only manageable by the most advanced computerized control systems. Some examples are: Stop the pump(s) at zero demand. Stop the pump(s) in case of water failure on the suction side (protection against dry running). Stop the pump if the required delivery exceeds the pump s capacity (protection against cavitation caused by excessive demand), or automatically switch on the next pump in a multiple series. Protect the pump and motor from over-voltage, undervoltage, overload, and earth fault. Vary the pump speed: acceleration and deceleration time. Compensate for increased flow resistance at high flow rates. Conduct automatic tests at set intervals. Monitor the converter and motor operating hours. Display all functions on an LCD in different languages (Italian, English, French, German, Spanish, Portuguese, Dutch). Send a signal to a remote control system which is proportional to the pressure and frequency. Communicate with another HYDROVAR or control system via an RS 8 interface. Control to match a system curve Control for constant flow Control according to an external signal 99

123 TECHNICAL APPENDIX 13

124 NPSH The minimum operating values that can be reached at the pump suction end are limited by the onset of cavitation. Cavitation is the formation of vapour-filled cavities within liquids where the pressure is locally reduced to a critical value, or where the local pressure is equal to, or just below the vapour pressure of the liquid. The vapour-filled cavities flow with the current and when they reach a higher pressure area the vapour contained in the cavities condenses. The cavities collide, generating pressure waves that are transmitted to the walls. These, being subjected to stress cycles, gradually become deformed and yield due to fatigue. This phenomenon, characterized by a metallic noise produced by the hammering on the pipe walls, is called incipient cavitation. The damage caused by cavitation may be magnified by electrochemical corrosion and a local rise in temperature due to the plastic deformation of the walls. The materials that offer the highest resistance to heat and corrosion are alloy steels, especially austenitic steel. The conditions that trigger cavitation may be assessed by calculating the total net suction head, referred to in technical literature with the acronym NPSH (Net Positive Suction Head). The NPSH represents the total energy (expressed in m.) of the liquid measured at suction under conditions of incipient cavitation, excluding the vapour pressure (expressed in m.) that the liquid has at the pump inlet. To find the static height hz at which to install the machine under safe conditions, the following formula must be verified: hp + hz (NPSHr +.) + hf + hpv where: hp is the absolute pressure applied to the free liquid surface in the suction tank, expressed in m. of liquid; hp is the quotient between the barometric pressure and the specific weight of the liquid. hz is the suction lift between the pump axis and the free liquid surface in the suction tank, expressed in m.; hz is negative when the liquid level is lower than the pump axis. hf is the flow resistance in the suction line and its accessories, such as: fittings, foot valve, gate valve, elbows, etc. hpv is the vapour pressure of the liquid at the operating temperature, expressed in m. of liquid. hpv is the quotient between the Pv vapour pressure and the liquid s specific weight., is the safety factor. 1 The maximum possible suction head for installation depends on the value of the atmospheric pressure (i.e. the elevation above sea level at which the pump is installed) and the temperature of the liquid. To help the user, with reference to water temperature ( C) and to the elevation above sea level, the following tables show the drop in hydraulic pressure head in relation to the elevation above sea level, and the suction loss in relation to temperature. Water temperature ( C) Suction loss (m),,7,, 7, 1, 1, Elevation above sea level (m) Suction loss (m), 1,1 1,6,,7 3,3 Friction loss is shown in the tables at pages of this catalogue. To reduce it to a minimum, especially in cases of high suction head (over - m.) or within the operating limits with high flow rates, we recommend using a suction line having a larger diameter than that of the pump s suction port. It is always a good idea to position the pump as close as possible to the liquid to be pumped. Make the following calculation: Liquid: water at ~1 C γ = 1 kg/dm 3 Flow rate required: m 3 /h Head for required delivery: 7 m. Suction lift: 3, m. The selection is an 33SV3G7T pump whose NPSH required value is, at m 3 /h, of m. For water at 1 C hp = Pa / γ = 1,33m, hpv = Pv / γ =,17m (,171 bar) The Hf flow resistance in the suction line with foot valves is ~ 1, m. By substituting the parameters in formula 1 with the numeric values above, we have: 1,33 + (-3,) ( +,) + 1, +,17 from which we have: 6,8 > 3,9 The relation is therefore verified.
