| Use advice for data set | Scope: This declaration applies to 1 piece of ALPHA2 GO 15,25,32-75/90 130,180 (Cast Iron) This EPD is a Representative EPD (inventory A1-A3, A4-A5, C1-C4) based on salesvolume with specific EPD (inventory B6) elements. The declaration covers the following variants: ALPHA2 GO 15-75 130 ALPHA2 GO 32-90 180 ALPHA2 GO 25-90 180 ALPHA2 GO 25-90 130 ALPHA2 GO 15-90 130 ALPHA2 GO 32-75 180 ALPHA2 GO K 25-75 180 ALPHA2 GO K 25-75 130 ALPHA2 GO 25-75 180 ALPHA2 GO 25-75 130 The product is assembled in Serbia. The life cycle assessment is based on data collected from the ERP system of the manufacturer, including data from the manufacturing plant. System boundary: This EPD is classified as a Cradle-to-Grave and module D. All major steps from the extraction of natural resources to the final disposal of the product are included in the scope of the study, following the modular approach of EN 15804. Modules A1-A3 refer to the product stage and include raw materials extraction and processing, transportation, and the manufacturing process. The product stage is included in this study, and according to EN 15804 the system boundary with nature is set to include those processes that provide the material and energy inputs into the system and the following manufacturing, transport up to the factory gate as well as the processing of waste arising from those processes. The assembly of the product, as well as the packaging, are included in A3. Wastes and losses are included in the modules where they occur according to the polluter pays principle and the modular approach of EN 15804. Module A4 regards the transportation from the production site to the regional distribution center, and finally to the construction and product application site. Module A5 refers to the installation process of the pump including the transportation of packaging waste to the treatment site and the waste treatment of packaging. The use of energy during installation is negligible for the selected functional unit. Modules B1-B7 refer to the use stage. All use stage modules are assessed in the study, though B1, B2 and B7 are assessed to be zero. The modules B3, B4 and B5 are declared as "MNR" (module not relevant) according to the PCR-B. Module B6 regards energy use during the operation of the pump and includes the electricity consumption of the product. The total electricity consumption over the reference service lifetime is assessed by calculating the average power input using a specified load profile and multiplying by the number of running hours per year and the number of years of the RSL. Modules C1-C4 refer to the End-of-life stage. A product reaches the end-of-life of its service life when it no longer provides any functionality. This life cycle stage includes all activities from the end-of-life of the pump until all materials and components are processed, reused, recycled, or disposed of. C1 regards the dismantling of the pump, and this module is a manual activity. C2 regards the transport to waste processing, C3 refers to the processing (shredding) of waste for recycling, and C4 refers to waste disposal: landfilling and incineration. The End-of-Life assumption is that 95 % is collected as electronic waste, while 5 % goes to landfill. Module D refers to the burdens and benefits beyond the system boundaries. According to EN 15804, module D includes the reuse, recovery and/or recycling potentials, expressed in net impacts and benefits. Contributions to module D come from waste incineration processes in A5 and C4 as well as material (metal) recycling in C3. The specific fractions and net flows are shown in the scenarios section of this declaration. | ||

| General comment on data set | ALPHA2 GO are high-efficiency variable speed circulator pumps fitted with an electronically commutated motor and designed for circulating liquids in heating and air conditioning systems. ALPHA2 GO is designed with intelligent control modes: constant pressure, proportional pressure, constant flow and constant curve. Each mode has adjustable setpoints. The AUTOADAPT setting, available for constant and proportional pressure, removes the need to manually select the pump setpoint. The Grundfos GO app offers a range of digital features that simplify the setup process for both new and replacement installations. The PWM input allows for precise control of the speed, better enabling complete system optimisation. Compliance: For placing pumps on the EU/EFTA market, a CE-marking is required. According to their Declaration of Conformity, these pumps comply with the following Council Directives: Machinery Directives: 2006/42/EC and 2009/127/EC Radio Equipment Directive: 2014/53/EU RoHS Directives: 2011/65/EU and 2015/863/EU EMC Directive: 2014/30/EU 2 3 These pumps are designed to provide reliable, efficient, and sustainable solutions for various heating and cooling applications, ensuring optimal performance and reduced energy consumption. ALPHA2 GO 25-90 180 has been selected as the representative variant. The pumps covered in the EPD were treated together as they physically represent identical or very similar products in terms of materials, weights, and contents of electronics. A representative pump model was applied for assessing the impacts of the A, C, and D stages. This representative variant was selected based on its high sales volume and is in fact, among the highest in environmental impact due to its relatively large pump housing (also larger than the weighted average pumphouse could have been). However, for the B stage, the individual impacts were considered. This entails impact calculation factors to be applied for B6, as outlined in the Results section. | ||
