What does ISO 2858 mean?

ISO 2858 is an international standard that defines the dimensions, tolerances, and testing requirements for centrifugal pumps designed for use in general industrial applications. The standard specifies the design and performance characteristics for these pumps, particularly the dimensions of the pump casing, impeller, and other key components.

Key aspects of ISO 2858:

1. Pump Design: It covers the design of horizontal centrifugal pumps, including their construction features, dimensions, and compatibility with other standard components.
2. Performance Standards: ISO 2858 outlines the expected performance characteristics of these pumps, including flow rates, head, and efficiency.
3. Material Selection: The standard may also include guidance on materials suitable for pumps, ensuring they meet the necessary requirements for durability and corrosion resistance, especially in industrial environments.
4. Pump Size and Connection: The standard specifies the pump sizes, including the diameter of flanged connections, the shaft dimensions, and other interface points, to ensure pumps can be interchanged or replaced without major modifications.

By adhering to ISO 2858, manufacturers ensure that their centrifugal pumps meet consistent quality, safety, and operational standards. This makes it easier for end-users to select pumps based on their needs and for engineers to integrate them into various industrial systems, knowing they comply with international benchmarks.

 ISO 2858 pumps are typically designed with features such as mechanical seals, flanged connections, and robust materials to ensure leak-free operation and durability.

(It’s important to note that this standard cancels and replaces the previous version, ISO 2858-1973. The current version of the standard was last reviewed and confirmed in 2017.)

CRESTS ISO RANGE

Did you know that in addition to our metallic pumps, our high efficiency EOV range is also manufactured in accordance with ISO2858. This means that although they may not look the same as the ISO pump you have on site, they are dimensionally equivalent, manufactured in the UK and even available from stock!

Also, as the EOV is British made at our factory in Hampshire we can accommodate your requirements with our flexible approach to design, seal requirements and motor specifications.
