How can industry awareness of the total cost of pumping system ownership?

Increasing industry awareness of the total cost of pumping system ownership through life cycle cost analysis is a goal of the US Department of Energy (DOE). This paper will discuss what DOE and its industry partners are doing to create this awareness.

Can a systems approach be used to analyze a pumping system?

In comparison, analysis of the pumping system using a systems approach could identify a varying load profile that could best be met through a two-pump arrangement or adjustable speed drive, resulting in a 50-60% savings. The results of a systems approach to analysis will vary from system to system and from facility to facility.

What makes a good pump purchase decision?

Purchase decisions for a pump and its related system components are typically based upon a low bid, rather than the cost to operate the system over its lifetime. Additionally, plant facilities personnel are typically focussed on maintaining existing pumping system reliability rather than optimizing the systems for best energy efficiency.

How much energy does a pumping system use?

Energy, typically electrical energy, is an important component of any examination of lifetime costs. Pumping systems in the United States manufacturing industries consume over 142 TWh per year. In the US petroleum industry, for example, 50% of the annual electricity use is for the operation of pumping systems (DOE 1998).

Where can I find an example of a hi/Europump analysis?

A good example of such an analysis is given in the HI/Europump Guide, and is also in the Guide’s Executive summary, available from the DOE BestPractices’ and Hydraulic Institute’s web sites ( and ).
