006-VTF4 Cartridge Variable Speed Solar Thermal Circulator Pump, 1/40 HP, Cast Iron, Rotated Flanged Connection

The Taco 006-VTF4 is a circulator with integral variable speed solar control. The unit integrates the advanced features of the external speed and solar controls with the dependability and ease of access of Taco's 00 cartridge circulators. This model is extremely easy to install and maintain, since all the wiring is done directly to the circulator and the LED status panel allows you to conveniently monitor and regulate the pump's functionality. The concept behind this unit is that if an appropriate delta T is maintained through the collector, then higher source temperatures can become available over longer periods of time, regardless of weather conditions. The 006-VTF4 continuously optimizes the flow through the collector in order to result in a maximum energy gain. This all-in-one solar circulator can be quickly installed in several solar applications, just with the flip of a dip switch!
