Allocation
System boundaries
In order to identify and quantify the significant environmental life cycle phase of Flygt
products an generic LCA was carried out The major findings of this LCA can be found in
Miscellaneous (page 8).
The data and calculations used conform with the "Product-Specific Requirements (PSR) -
Submersible pumps and mixers" (PSR 2002:5).
The functional unit is defined as the hydraulic power of the pump at best efficiency point
expressed in kW.
Table 1: Declaration of contents, with the quantity of every material specified as a proportion
of the total pump weight in kg, and kg per functional unit.

Environment performance
The allocation factor for the environmental impact during the production phase is
calculated as the ratio of the product weight to the total produced pump weight for the
relevant factory during one year.
The system boundaries for the LCA that serves as a basis for this EPD is according to the
figure below.
