scope:

1.1 Pump technology This European Standard covers glanded water pumps for pumping clean water, including where integrated in other products. Pumps designed and produced as low duty pumps for pressures up to 16 bar for end suction pumps and up to 25 bar for multistage pumps, temperatures between -10 and +120°C, for clean water, in all kinds of material. 1.2 Pump types - End suction and in-line pumps for design pressure up to 16 bar (incl. EN 733 or equivalent). - Vertical multistage pumps with design pressures up to 25 bar. - Submersible multistage pumps designed to operate in boreholes at operating temperatures within a range from 0°C to 90°C. - For special design of pump types specified in this paragraph the test procedure described in section 7.5.4 shall be considered. NOTE 1 The pump types and sizes within the scope are typically mass produced pumps. Larger pumps at the upper end of the scope might be produced in smaller numbers. NOTE 2 See informative Annex B for further information.
