The 59896778 from Grundfos is a UP15-29SUC 1/8HP Stainless steel 3-Speed Circulator Pump with a removable Integral Check Valve, 1-1/4" (GU125) union connections. This circulator model can be easily integrated into the system by adjusting the speed (Low/Med/High) and thus matching the system's requirements. Built-in check valve performs better than traditional in-line check valves and eliminates the need to buy and install a separate one.
