Process Pump Standards Summary
The quality of process pumps used in industrial operations is critical to the successful and safe operation of processes, particularly in the chemical and petrochemical industries. To ensure that process pumps meet the highest quality standards, a number of different standards have been developed and adopted by most major pump manufacturers. This article summarizes some of the major standards relating to process pumps and their components, as well as how they apply to their use in various types of applications.
API 610
The American Petroleum Institute (API) 610 is the most comprehensive and widely recognized standard for process pumps. The standard sets out rules and regulations for the design, manufacture, rating, testing, and performance of centrifugal pumps used in the oil and gas industry. The standard applies to all pumps used in these industries, including both frame and canned motor pumps. The standard is periodically updated to reflect advancements in pump technology, as well as changes in safety, environmental, and operational requirements.
ISO 2858
The International Organization for Standardization (ISO) developed the ISO 2858 standard to describe the characteristics and performance requirements of centrifugal pumps. The standard is applicable to centrifugal pumps with single entry, double suction, or multi-suction impellers. The performance requirements defined by the standard include maximum flow rate, impeller efficiency and other important pump operating characteristics.
ANSi/HY 14.1
The American National Standards Institute (ANSI) developed the ANSI/HY 14.1 standard to describe the requirements for the design, manufacture, testing, and performance of pumps intended for the transfer of water or other liquids in commercial, industrial, and service applications. The standard outlines the requirements for pumps, motors, valves, and other components and is applicable to both centrifugal and positive displacement pumps.
NEMA V2 and V7
The National Electrical Manufacturers Association (NEMA) developed the V2 and V7 standards to define the requirements for electric motors intended for use in process pumps. The V2 standard applies to motors rated 7.5 HP or less and the V7 standard is applicable to motors rated 7.5 HP or more. The standards set forth a variety of requirements and performance characteristics, including power ratings, environmental protection, input voltage, safety considerations, and operating temperature.
DIN 24255 and 24256
The Deutsches Institut für Normung (DIN) developed the DIN 24255 and 24256 standards to describe the requirements for the design, manufacture, testing, and performance of process pumps. The standards are applicable to centrifugal and positive displacement pumps, and outline the requirements for performance, safety, safety marking, and vibration levels.
In addition to the standards described above, there are numerous other standards that cover various aspects of process pumps and their components. These include standards such as API 618, ISO 5199, ANSI/HY 14.15, and NEMA MG 1. In general, these standards should be consulted before purchasing any process pump, as they provide guidelines for the performance and safety of your pumps.
