Grundfos 98126840 MAGNA3 50-80 F Variable Speed ECM Circulator, Cast Iron, Flanged, 1/3 HP, 208-230V

The Grundfos 98126840 is a MAGNA3 50-80 F electronically commutated (ECM) variable speed circulator with a cast iron pump housing and flanged connections, for commercial and large residential hydronic heating and cooling systems.

MAGNA3 is the Grundfos choice when system control and monitoring matter: it connects to the Grundfos GO app over Bluetooth and supports fieldbus communication through optional CIM modules. Control modes include AUTOADAPT as well as proportional-pressure, constant-pressure and constant-curve operation. The cast iron housing is intended for closed-loop heating and chilled water systems. This 50-80 model is rated for a maximum head of 26.25 ft and flows up to about 110 GPM.

Before ordering: confirm your supply voltage (208/230V, single phase), the flange size and bolt pattern for the 50-80 model, and that matching flanges and gaskets are on hand.
