ISO 17769 Document Information:
Title
Liquid pumps and installation — General terms — Definitions, quantities, letter symbols and units
International Organization for Standardization
Publication Date:
Mar 15, 2008
Scope:
rotodynamic and positive displacement liquid pumps and
associated installations. It serves as a means of clarifying
communications between the installation designer, manufacturer,
operator and plant constructor.
This International Standard identifies the units in common usage
but, all other legal units can be used.
This International Standard deals solely with conditions
described by positive values for the rate of flow and pump head.
The definitions are set out showing first the most common form of a
quantity followed by some frequently used variants. Other variants
can be constructed and appropriate symbols evolved using the
symbols and subscripts shown. Prefixes such as "working" and
"design" can also be applied to the defined quantities.
This International Standard is not concerned with terms, letter
symbols and units referring to the component parts of rotodynamic
and positive-displacement pumps and installations.
Whenever possible, symbols and definitions conform to those used
in ISO 31-0 and ISO 1000, with further explanations where these are
deemed appropriate. Some deviations have been incorporated for
reasons of consistency.
