Centrifugal Pump Specifications
Centrifugal Pump Annex G outlines specific specifications that centrifugal pumps must meet to ensure their proper functioning and longevity. These specifications cover various aspects of the pump, including design, materials, performance, and testing. Manufacturers must carefully design their pumps to meet these specifications to guarantee optimal performance and reliability.
One key specification outlined in Annex G is the pump's capacity, which refers to the maximum flow rate the pump can handle. This parameter is crucial for determining the pump's suitability for a particular application. Additionally, the pump's head, efficiency, and power requirements are also specified to ensure that the pump operates efficiently and effectively.
Centrifugal Pump Standards
In addition to specifications, Centrifugal Pump Annex G also references various international standards that manufacturers must follow when designing and manufacturing centrifugal pumps. These standards cover a wide range of aspects, including materials, performance testing, safety requirements, and environmental considerations.
One of the essential standards referenced in Annex G is ISO 5199, which provides general requirements for centrifugal pumps used in chemical process industries. This standard outlines specific design and performance criteria that manufacturers must adhere to when producing pumps for chemical applications. By following these standards, manufacturers can ensure that their pumps meet industry best practices and regulatory requirements.
Centrifugal Pump Requirements
Centrifugal Pump Annex G sets forth specific requirements that manufacturers must meet to ensure the quality and reliability of centrifugal pumps. These requirements cover various aspects of pump design, construction, testing, and performance. By adhering to these requirements, manufacturers can demonstrate that their pumps are safe, efficient, and compliant with industry standards.
One critical requirement outlined in Annex G is the need for thorough testing and validation of centrifugal pumps before they are put into service. Manufacturers must conduct various tests, such as performance testing, hydrostatic testing, and vibration testing, to ensure that the pump meets all specified criteria. Additionally, manufacturers must provide documentation and certification to demonstrate compliance with the requirements outlined in Annex G.

The volute casing pump is the most common type of centrifugal pump.. Its characteristic feature is the volute-shaped pump casing which is typical for single-stage centrifugal pumps.. There are designs whose main dimensions are standardised in accordance with EN 733, ISO 2858 and ISO 5199, but this standardisation still leaves ample room for many design variants.
