TS EN 12723

TS EN 12723 brings together the core terms, quantities, letter symbols and units used for liquid pumps and pump installations in a common technical language. Its focus is the harmonisation of pump-related terminology, so that concepts connected with performance, operation and system design can be understood consistently across languages and application contexts.

A common reference frame for pump terminology

From a general technical perspective, pump terminology keeps concepts such as flow rate, head, power, efficiency, inlet conditions and discharge conditions distinct from one another. In liquid pumping, those terms matter because the same physical quantity can be interpreted differently depending on the operating point, the installation layout or the measurement context. Terminology standards help make those distinctions clear in engineering drawings, catalogues, calculations and technical documentation.

The kind of information this standard organises

• General terms related to pumps and pump installations
• Names of quantities used in technical description
• Letter symbols used in engineering notation
• The units associated with those quantities

As a terminology standard, the document is not a design or test standard for a specific pump type; it is a reference framework for how concepts should be named and expressed. That makes it especially useful in cataloguing, specification writing, training material and multilingual technical communication. TS EN 12723 serves as a basic vocabulary framework that helps reduce ambiguity in the technical language of liquid pumps.
