Warrenton’s SW Alder pump station was rapidly reaching the end of its life. The station was equipped with two 10-hp pumps designed to generate 400 gpm at 34-foot total dynamic head feeding into a shared force main. But the pumps had diffi culty meeting this requirement and often wound up running against shutoff head at the primary pump station.
The city decided to upgrade the wet well and controls in 2013. Following an RFP process, they selected Flygt — Portland’s proposal containing key elements from the Flygt Experior package consisting of two NP3127 10-hp submersible pumps fi tted with Hard-Iron™ N-impellers and 10-hp SmartRun controls.
