VFD Duplex Pump Control Panel
Intelligent pump control with Variable Frequency Drive, PLC automation, and 7" HMI touchscreen. Constant pressure, energy savings of 20-35%.
Overview
Our VFD duplex pump control panels are the brain of any modern water distribution system. The Variable Frequency Drive adjusts motor speed in real-time based on demand — when water usage drops, the pump slows down instead of cycling on/off. This delivers constant pressure, reduces energy consumption by 20-35%, and dramatically extends motor life. The duplex configuration runs two pumps in lead/lag alternation — one runs while the other stands by, with automatic switchover for even wear distribution and zero-downtime redundancy. Full PLC automation with 7" color touchscreen for real-time monitoring, alarm history, and parameter adjustment.
