Evaluating Pump Energy Savings

Energy Savings — Introduction

One of the biggest expenses today in liquid processing operations is the cost of energy. It is not uncommon for the cost of wasted energy in a continuous pump service over a period of two years or less to surpass the initial cost of the pump.

As a result, more attention in our current "competitive" era is being directed toward reducing operating costs. Higher pump efficiencies, along with higher motor efficiencies, are immediate solutions. Other, equally-important factors include system design and pump application. In this issue of The Pump Primer, we will approach the subject of energy savings from each of these aspects.

Pump Efficiencies

The most-obvious, direct savings in the pump unit results when a smaller-size drive can be used because of a pump's higher efficiency and non-overloading performance characteristics.
