Geo-Flo Products Corp. unveils its NP Series family of nonpressurized flow centers used for closed-loop geothermal (ground-source) heat pump systems. The NP Series uses a water column to provide the necessary suction head for the circulator pump and to ensure a flooded pump volute. Each flow center features a fluid reservoir (tank), flush and service valves, and one or more pumps housed in a foam-insulated cabinet. The NP Series is manufactured with single-speed, three-speed and variable-speed pumps to provide a variety of design and installation options.www.geo-flo.com
