The Hydraulic Institutue has suggested that 85% of pumps in the USA have been incorrectly selected for their duty. Overly conservative duty points result in the pump operating to the right of their best efficiency point. Simply changing the impeller may be all that is necessary to reduce your energy usage by 25%. A change to a smaller pump can acheive savings in energy usage and ongoing maintenance.
We can analyse your system and recommend changes to pumps that can save your energy bills.
