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 /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-sh 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.

26 ErP 9/1/EC ESH SERIES PUMPS With the Energy using Products (EuP /3/EC) and Energy related Products (ErP 9/1/EC) directives, the European Commission has established requirements for promoting the use of products with low power consumption. 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 pumps (ESCC for the Regulation) and end-suction own-bearing pumps (ESOB 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 1 bar (1 kpa); pumps with a minimum nominal flow not less than 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 ESHE and ESHS versions correspond to the end-suction close-coupled pump while ESH, ESHF and ESHC versions correspond to the end-suction own bearing 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. ) 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. ) 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 Ecodesign,Efficiency charts (refer to ESCC 1 rpm, ESCC 9 rpm, ESOB 1 rpm, ESOB 9 rpm ).

96 ESH..H (ESH WITH HYDROVAR) 9

97 ESH..H SERIES (ESH WITH HYDROVAR) Background and context In all areas of application, such as building services, industry, agriculture and air-handling, the demand for intelligent pumping systems is constantly growing. There are many advantages: reduced cost for pump life cycle, lower environmental impact, longer lifetime of pipes and unions. That s why Lowara has developed the ESH..H: an intelligent pumping system which assures high level performance with energy consumption tailored to demand. Benefits of NSC with HYDROVAR Saving: ESH..H transforms ESH pumps into variable speed intelligent pumping systems. Thanks to the HYDROVAR system, the speed of each pump varies so as to maintain a constant flow or pressure or differential pressure. The pump only receives the energy required, thus allowing considerable savings, especially for those systems in which demands varies during the day. Special features / benefits There is no need for additional pressure sensors: ESH..H are fitted with a pressure transmitter or differential pressure transmitters, depending on the application. There is no need for special pumps or motors. There is no need for bypass or safety systems: with HYDROVAR the pump immediately switches off when demand drops to zero or when it exceeds maximum pump capacity. This makes it unnecessary to install additional safety devices. Anti-condensation device: all units are 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: ESH..H saves time and space during installation. Installed directly on the motor (up to kw), which cools it down, and does not require a further control panel., only fuses on the supply line (will depend upon any local electrical installation regulations). The wall-mounted HYDROVAR version is available for higher power outputs (up to kw). Standard motors: ESH..H models are fitted with three-phase standard TEFC motors with insulation class 1 (F). NSC_M_A_ot 97

98 ESH..H SERIES (ESH 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. In addition to these basic functions, HYDROVAR can do things only by the most advanced computerised control systems, such as: 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 overvoltage, undervoltage, overload and earth fault. Vary the pump speed acceleration and deceleration time. Compensate for increased flow resistance at high flow rates. Conduct automatic test starts 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 interface. Control for constant pressure Control to match a system curve Control for constant flow Control according to an external signal 9

109 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,,,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:, > 3,9 The relation is therefore verified. 19 TECHNICAL APPENDIX

The values given are guideline values which are bound to vary slightly according to the model, especially for gate valves and non-return valves, for which it is a good idea to check the values supplied by manufacturers.
