GRUNDFOS - ALPHA 15-58F 115V 9H - 92603115

The Grundfos ALPHA 15-58 F Circulator Pump, MPN 92603115, is a high-efficiency 115V ECM pump engineered for residential and light-commercial hydronic heating and cooling systems. Its intelligent controls include AUTOADAPT, proportional-pressure, constant-pressure and constant-curve operating modes for accurate, energy-saving circulation. The cast-iron flanged pump features dry-run protection, self-venting capability, air detection and Bluetooth connectivity through the Grundfos GO app. Ideal for radiant floor heating, baseboard systems, boilers, fan coils and zone-controlled HVAC applications, the ALPHA 15-58 F provides quiet operation, simplified setup and reliable closed-loop water circulation.

Grundfos’s competitor chart places the ALPHA 15-58 family alongside these common circulators; they are not guaranteed drop-in replacements for every installation.

Usage

The Grundfos 92603115 is installed in a closed-loop hydronic system to move heated or chilled water between a boiler, heat pump or chiller and the connected heat emitters. Typical applications include radiant-floor manifolds, hydronic baseboard loops, radiators, fan-coil units and boiler zone piping. The pump is mounted inline using its flanged connections, with the motor shaft kept horizontal. After filling and purging the system, the installer selects AUTOADAPT or another control mode to match system demand. Dry-run protection helps protect the circulator when adequate water is not detected.
