Pump Performance Chart

ISO 2858 vs ISO 5199

Even though the ISO 2858 and the ISO 5199 cover the same type of industrial pumps, they are different.

ISO 5199 covers the technical specifications for Class II centrifugal pumps of single stage, multi-stage, horizontal or vertical construction, with any drive and any installation for general application. Pumps used in the chemical process industries (e.g. those conforming to ISO 2858) are typical of those covered by this standard.
ISO 2858 specifies the principal dimensions and nominal duty point of end suction centrifugal pumps having a maximum operating rating of 16 bar.

To sum up, ISO 2858 focusses on external dimensions and mounting details, while ISO 5199 also specifies a variety of performance requirements and construction features.
