Anglian Water trials using variable speed drives (VSDs) to control the speed of Archimedes screw pumps, resulted in a three-month energy savings of £26,000 across three wastewater treatment sites. It also helped to reduce wear on the associated belts, drive chains and bearings. Each site uses three Archimedes screw pumps each controlled by a 90 […]
Growing health and hygiene interests, along with the pandemic have increased the volume of non-flushable items in the wastewater system. Our pursuit for convenience and healthy personal habits also means non-flushable items like wet wipes will continue to grow. Changing public perceptions and pumps using anti-jam technology offer a solution. Despite the marketing, these products […]
In a new whitepaper, ABB reveals the potential for significant energy efficiency improvements in industry and infrastructure enabled by the latest high efficiency drives and motor systems. They call on governments and industry to speed up the adoption of the technology to help combat climate change. According to the International Energy Agency (IEA), industry accounts […]
Environmental concerns and optimising energy costs are strong drivers for an end-user’s economic policy. As a consequence, Total Cost of Ownership (TCO) is an important factor when making investment decisions. System design is key to TCO and influences any purchasing decision, such as the design of a pump control system. Total Cost of Ownership (TCO) […]
The benefits of using VSDs with motors are well documented, however for some applications the installer must use caution. Using a long VSD cable between the drive and the electric motor can have a major impact on performance and cause premature ageing. For example, long cable runs between the drive, and motor may cause […]
