Pump controller from Bell & Gossett
Bell & Gossett’s TECHNOLOGIC VFD series combines two advanced controller functions — the Start-Up Genie and an electronically controlled bypass — engineered to reduce onsite setup and configuration time. A built-in Auto set mode is available that remembers previously set parameters, enabling users to quickly make adjustments without inputting measurements. Setup time is about 15 minutes and it has the ability to alter hydraulic performance to maintain constant system pressure. The drive provides constant speed lag control and the ability to control one variable-speed pump with up to two fixed-speed lag pumps triggered by relay.
