TS EN ISO 17769-2

TS EN ISO 17769-2 is a technical terminology standard for liquid pumps and their installations, covering general terms, definitions, quantities, letter symbols, and units used in pump-system documentation. It provides a common language for engineering, procurement, design, and technical communication, so that the concepts surrounding pumping systems are described consistently rather than in ad hoc wording. In practical terms, the subject is not a pump model itself, but the vocabulary and measurement framework used to describe a pump system.

Why shared terminology matters in pump systems

In pump engineering, inconsistent use of terms can easily create ambiguity around flow rate, head, efficiency, suction conditions, discharge conditions, and system components. Terminology standards help align how these concepts are written in drawings, data sheets, manuals, test reports, and specification documents. From a general technical perspective, they make the distinction clearer between the pump as a machine and the installation as a complete operating system, including piping, valves, tanks, and other connected elements that shape overall performance.

What this standard covers in general technical context

Based on its title and classification, this document is best understood as a shared vocabulary for liquid pumps and installations, not as a source of proprietary design limits, mandatory test procedures, or numerical performance requirements. In pump systems, precise terminology is essential for separating basic concepts such as fluid properties, flow and pressure relationships, suction and discharge sides, operating point, and system curve. A standard of this type supports consistent use of symbols and units across industries and helps engineers communicate the same physical quantities without ambiguity.

This listing is presented as an EN ISO 17769-2:2012-based standard, with the Turkish title indicating a sectional presentation. Only the general technical framework can be stated confidently from the title and metadata; the detailed clause-by-clause content, exact defined terms, and any internal symbol lists should be verified against the full text.
