Flo-Link double O-ring style flow centers are unsurpassed in ease of installation. Flo-Link double O-ring fittings provide leak-free union connections at the flow center, installed without tools (no need for pipe wrenches). Virtually any type of transition (fusion, thread, barb, PVC glue, etc.) is available for Flo-Link fittings. Geo-Flo’s full port 3-way, 4-position flushing and isolation valves are designed for the wide range of temperatures experienced in ground loop applications. The die cast brass valves are cast in the United States, and CNC machined in our factory to exacting tolerances. All Flo-Link flow centers include pump volutes designed exclusively for Geo-Flo in a joint engineering effort with Grundfos Pumps Corporation. This design allows the entire power head (pump motor and electronics) to be external to cabinet. This provides additional flexibility for installers and service technicians when a pump head needs to be rotated, or when a single pump flow center needs to be upgraded to a two pump flow center. In addition, it assures that the condensate weep holes in the pump’s stator housing are completely exposed, allowing any internal condensation build-up to safety exit the pump motor.Features: Simple installation using Flo-Link™ Double O-Ring Fittings that eliminate the possibility of leaks from leak prone tapered pipe threads Front flush ports Foam insulated cabinet stops condensation High Impact Polystyrene Cabinet will not rust Fully assembled and leak tested Utilizes industry standard Grundfos circulators (one and two pump modules available) Constant speed and ECM variable speed pump options Single pump flow center can be field upgraded to two pump flow center Show more
