Wet-rotor pump
January 15, 2013
Taco’s Viridian is an ECM motor-driven wet-rotor pump that offers an 80% decrease in energy consumption compared to a standard commercial pump of the same size. With fully automated variable-speed operation, simple Web-style controls and capacities up to 375 gpm, the Viridian line meets the widest range of closed-loop heating and cooling applications. An Ethernet connection on the pump allows for remote control monitoring and adjustment without requiring the involvement of advanced IT or commissioning personnel.
