Grundfos MAGNA3 50-80 FN Stainless Steel Circulator Pump, GF 53 Flange (1/3 HP, 208/230V)

MAGNA1 50-80 FN Stainless Steel Circulator Pump, GF 53 Flange (1/3 HP, 208/230V) MAGNA1 circulator pump with easy selection of pump setting The pump is of the canned-rotor type, i.e. pump and motor form an integral unit without shaft seal and with only two gaskets for sealing. The bearings are lubricated by the pumped liquid. In order to avoid problems in connection with disposal, great importance has been attached to using as few different materials as possible. A pump with no maintenance requirements and extremely low life cycle cost. The MAGNA1 circulator pumps are designed for circulating liquids in heating systems with variable flows where it is desirable to optimize the setting of the pump duty point, thus reducing energy costs. The pumps are also suitable for domestic hot-water systems. To ensure correct operation, it is important that the sizing range of the system falls within the duty range of the pump. The pump is also suitable for systems with hot-water priority as an external signal can immedi...
