Pumps driving industry to improve


By Linda Dingley, Grundfos Pumps Ltd

herever you are sitting, you won’t be far from a series of pumps that are performing a


multitude of tasks and that are key to your business. These pumps will be playing a variety of roles such as supporting the heating, ventilation and air conditioning requirements, as well as maintaining water pressure, delivering and distributing clean drinking water and removing grey/ wastewater and these are just the basics. Regardless of what industry you are involved with, a range of pumps will be in situ and playing a key role delivering many of the functions that you need to literally, keep your business running. In fact looking at the bigger picture the wider world depends on them too but pumps are also serious energy wasters, leaving behind a signifi cant carbon footprint. This means that pumps stand out as offering the single biggest savings opportunities to a business as: ■ today pumps account for 10% of the world’s electrical consumption.


■ two thirds of all the currently installed pumps use up to 60% too much energy. ■ if every company switched to a high effi ciency pump system there could be global savings of 4% of the total electricity consumption – comparable with the residential electricity consumption of 1 billion people.


When to replace/upgrade In the main, it is very rare for anyone to consider switching a pump for any other reason than it has developed a problem that means it has reached the end of its life. Yet there are many other opportunities when to do so would result in better comfort and/or performance levels, improved energy effi ciency and therefore reduced emissions. So looking at replacing either individual pumps or whole pumping systems prior to when it’s absolutely essential can have a short pay-back period. Pumps operating within an industrial environment require replacement for many reasons. When this happens, it offers the opportunity to review the system and make sure it is delivering the most effi cient solution for that particular building against its individual blueprint. Whatever the circumstances, it is worth reassessing the situation as depending on the application there are large fi nancial savings to be made by taking the opportunity to change to a more effi cient option. Our experience tells us that, for the most part, pumps are directly replaced with a ‘like for like’ solution, without any extra consideration and this means that the opportunity to optimise on a replacement selection is lost.


Check out your pump equipment However, there is a better way. For example, if you want to quickly assess what savings could be realised to your current pump systems, contact a pump company who offers this service and they can undertake an energy survey that will assess all the installed pump equipment and will look at the current and future demands of that system. They will then produce a comprehensive report that will document any suggested changes and the potential savings that they offer, along with giving an overview on the return on investment (ROI), CO2 saving and a complete life cycle cost.
