Centrifugal pumps are a widespread industrial workhorse, accounting for roughly 16 percent of the energy consumed by industrial electric motors worldwide [1]. For the health of both the planet and your wallet, it\u2019s vital to run them at peak efficiency. In this article, we\u2019ll show you four fast, low-cost ways that real-time machine data can help you start lowering pump power consumption and emissions.<\/p>\n

There are several ways to lower a centrifugal pump\u2019s energy consumption. Generally speaking, we can divide these strategies into two classes: short-term changes to existing machines, operations and practices, and long-term changes that focus on redesigning part or all of the system. These long-term changes can produce extensive savings, but they take months of planning and significant investments. In this blog post we\u2019ll look at some short-term changes that don\u2019t require large capital expenditures. All you\u2019ll need to get started is a way to see how your pump is performing in real time \u2014 and chances are, you already have it.<\/p>\n

Step 1: Use real-time machine data you\u2019re already collecting<\/strong><\/h2>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n

There are three pump performance parameters you can use to identify inefficiencies \u2014 and you\u2019re probably already tracking at least one of them. The readings from flow, power and pressure sensors can be used to calculate the pump\u2019s energy consumption.<\/p>\n

Flow and pressure data<\/strong><\/h3>\n

Flow meters and pressure meters do not directly track a pump\u2019s energy consumption. However, they track two key parameters that enable you to estimate it pretty well. You don\u2019t have to do the math yourself \u2014 in step 2, we\u2019ll look at tools that will do it for you. But if you\u2019re interested,\u00a0Neutrium\u2019s engineering encyclopedia<\/a>\u00a0explains how you can turn pascals and liters-per-second into kilowatt-hours.<\/p>\n

Power data<\/strong><\/h3>\n

If you\u2019ve installed power sensors to directly measure the pump\u2019s actual power consumption in real time, you\u2019re in an even better position. While flow and pressure data can give you some high-level insight into a pump\u2019s energy use, without power data they depend on static estimates of pump and motor efficiency. These are often idealized numbers that may or may not have been true when the pump was brand new, but are almost certainly no longer accurate as the pump ages.<\/p>\n

What\u2019s more, operational conditions can change the pump\u2019s actual efficiency from one moment to the next, regardless of its rating. For example, periods of lower demand can put such a low load on the pump that it runs very inefficiently, even though its efficiency is fine at its usual load. It\u2019s these operational factors that enable most of the quick, low-cost changes that will save energy. Sensors that directly measure the current and voltage being drawn by the system provide all the detail you need to track these factors.<\/p>\n

Step 2: Run energy analytics on that data<\/strong><\/h2>\n

You might already have the expertise in house to analyze your flow, power and pressure data from an energy-savings perspective. If not, there are plenty of modern energy intelligence platforms that can ingest your existing data and analyze it to provide detailed recommendations.<\/p>\n

If you decide to go with an external platform, here are some things to look for:<\/p>\n
