Yaskawa U1000 MATRIX VFD Wastewater Lift Pump Retrofit Case Study

This document details a case study where a Midwest wastewater treatment facility replaced a failing 18-pulse AC drive system with a Yaskawa U1000 Industrial MATRIX VFD to power four 350 HP lift pumps. The retrofit met strict form factor, low harmonic, and thermal efficiency requirements, resulting in a 5% efficiency gain, reduced heat output, and lower project costs.
