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

closed-loop system with controlled pressure and vacuum relief and\u003cstrong\u003e incorporate 3-way valves for system flushing\u003c\/strong\u003e.  The pressure relief valve allows the system to be pressurized to 13 PSIG, which no other non-pressurized product can claim.  This is important since geothermal HDPE loop pipe contracts when the system is in heating mode increasing system pressure.  Further, our NP products include a vacuum relief valve (built into the cap) that is closed during normal operation, but opens when the system pressure drops below atmospheric pressure.  This is important since the loop pipe expands during cooling mode decreasing system pressure.  Without this important function, the tank\/system pressure will drop creating a vacuum that decreases the positive suction pressure on the pumps.\u003cbr\u003e\u003cbr\u003eGeo-Flo’s 3-way flushing valves with \u003ca
