TS EN 12723
Liquid pumps – General terms for pumps and installations – Definitions, quantities, letter symbols and units
The document deals with terms, letter symbols and units related to the flow of liquids through rotodynamic and positive displacement liquid pumps and associated installations. The document identifies the units in common usage. A definition of a liquid pump is included. The document is not concerned with terms, letter symbols and units referring to the component parts of rotodynamic and positive displacement pumps and installations.

About This Item
TS EN 12723 is a terminology and units standard for liquid pumps and the associated installations around them. It focuses on the terms, letter symbols and units used to describe liquid flow in rotodynamic and positive displacement pumps, helping different parties use the same technical language when discussing pump performance and system behaviour.
Why a shared vocabulary matters in pump engineering
In pump applications, concepts such as flow rate, pressure, head, speed, efficiency and suction conditions are closely related but not interchangeable. The general purpose of this standard is to align how these quantities are named and represented. That makes it easier to compare catalog data, communicate design intent, discuss installation behaviour and avoid ambiguity between designers, manufacturers, operators and installation contractors. The value of the document lies in consistency of language rather than in prescribing a pump design method.
What the document covers and what it leaves out
- Terms related to rotodynamic and positive displacement liquid pumps.
- Vocabulary connected with the flow of liquids through those pumps and associated installations.
- Units in common usage, together with the relevant letter symbols.
- A definition of a liquid pump.
- It does not address terms, symbols and units for individual component parts of those pumps and installations.
From a general technical perspective, rotodynamic pumps transfer energy to a liquid through an impeller and flow dynamics, while positive displacement pumps move a defined volume by repeating mechanical displacement. Because these pump families work on different principles, a term or symbol can carry different nuances depending on context. A standard like TS EN 12723 is therefore useful as a common reference framework for documentation, specification writing and operational communication across the pump sector.
This edition has been withdrawn, but it still reflects the foundational terminology used to organise pump-related quantities, symbols and units in a consistent way.
