ISO has released the new international standard ISO/ASME 14414, Pump system energy assessment.
Developed in conjunction with the American Society of Mechanical Engineers (ASME), ISO/ASME 14414 sets the requirements for conducting and reporting the results of a pumping system assessment, allowing facilities to not only calculate their current energy consumption but identify ways to reduce energy and improve its efficiency.
The standard aims to reduce energy consumption by enabling organisations to effectively determine the minimal amount of energy that is required by various pump systems, thus enabling facilities to improve energy efficiency, subsequently reducing consumption and as a result their costs and carbon footprint.
By providing a common definition for an assessment, it also enables consistency across organisations and countries, ensuring contracting for assessment services is a whole lot easier.
The objective of a pumping system energy assessment is to determine the current energy consumption of an existing system and identify ways to improve system efficiency. Therefore it should consider the entire pumping system, from energy inputs to the work performed as the result of these inputs.
The standard covers:
- organising and conducting an assessment,
- analysing the data from the assessment, and
- reporting and documenting assessment findings.
It is designed to be applied to open and closed loop pumping systems typically used at industrial, institutional, commercial, and municipal facilities.
ISO/ASME 14414:2014 is focused on assessing electrically-driven pumping systems, which are dominant in most facilities, but is applicable with other types of drivers, such as steam turbines and engines, and drives such as belt.
“Pump systems are used to move liquids across a wide range of applications within industrial processes, buildings and transportation,” said ISO. “But all too often they use more energy than they really need to fulfill the process demands in the plant.”
