Case Study 4:  Comparison on DIN 24255/ EN 733 vs ISO 2858/ 5199 vs API 610 Standard on End Suction Centrifugal Pumps

 



End Suction Centrifugal Pump Standards


The standards DIN 24255/EN 733, ISO 2858/5199, and API 610 outline specifications for various types of centrifugal pumps, each serving different purposes in design, manufacturing, and testing. Here's a brief overview of the differences between these standard:


  • DIN 24255/EN 733:
  1. Application: Primarily used in Europe, especially in Germany.
  2. Design: Standardized by the Deutsches Institut für Normung (DIN) and later adopted by the European Committee for Standardization (CEN) as EN 733.
  3. Features: Commonly applied in general industrial applications, heating, air conditioning, and water supply systems.
  4. Characteristics: Standardized dimensions and performance criteria for a wide range of pumps.


  • ISO 2858/5199:
  1. Application: International standard widely recognized globally.
  2. Design: Set by the International Organization for Standardization (ISO).
  3. Features: Applicable for general industrial use, chemical processing, and other applications requiring standardized pump dimensions and performance.
  4. Characteristics: Provides a globally accepted framework for pump design and testing, ensuring interchangeability of pumps from different manufacturers.


  • API 610:
  1. Application: Widely used in the oil and gas industry and other heavy-duty applications globally.
  2. Design: Established by the American Petroleum Institute (API).
  3. Features: Tailored for demanding applications such as petrochemical, refinery, and offshore industries, emphasizing reliability and robustness.
  4. Characteristics: Specifies stringent requirements for materials, design, and testing to ensure pumps meet the challenges of heavy-duty and critical services.



In summary, while DIN 24255/EN 733 is common in Europe for general industrial applications, ISO 2858/5199 provides an international standard suitable for various industries. On the other hand, API 610 is recognized globally, specifically catering to the stringent demands of heavy-duty applications in the oil and gas sector.

Price Level Cost effective Moderate Higher initial investment

The selection among DIN 24255/EN 733, ISO 2858/5199, and API 610 standards is contingent upon the specific requirements of the application. Factors like pressure, temperature, fluid characteristics, and the criticality of the process play a crucial role in this decision. Each standard possesses its unique strengths and is crafted to address distinct industry needs. In simpler terms, when comparing the standards for end-suction centrifugal pumps - ISO 2858/5199 and API 610, with DIN 24255/EN 733,  ISO 2858/5199 and API 610 standards could serve more benefits, bringing more value to the industrial, petrochemical, and oil & gas applications. As a result, EMMECOM has chosen to incorporate pumps adhering to ISO and API standards into our product range, providing efficient pumping solutions for diverse and demanding industries.


However, DIN 24255/EN 733 standard end-suction centrifugal pumps are not part of our product offerings. This decision is based on our strategic focus, as we don't primarily cater to general industries where water applications are prevalent. By specializing in ISO and API standards, we aim to deliver specialized and reliable pumping solutions tailored to the specific needs of industrial, petrochemical, and oil & gas sectors.
