Grundfos 99490916 ALPHA2 26-99 Variable Speed ECM Circulator with Check Valve, Cast Iron, Flanged, 115V

The Grundfos 99490916 is an ALPHA2 26-99 variable speed circulator with an electronically commutated (ECM) motor, a flanged cast iron body and a built-in non-return (check) valve, for hydronic heating systems.

ALPHA2 circulators adjust speed to system demand and include the AUTOADAPT setting, which selects the pump curve automatically, along with proportional-pressure, constant-pressure and constant-curve modes. The 26-99 size reaches about 27.5 GPM and a maximum head of 42 ft. The built-in check valve helps prevent reverse flow and gravity circulation through the zone.

Before ordering: the pump runs on 115V, single phase, with flanged connections. Make sure you have a matching 2-bolt flange set for your pipe size.
