ALPHA is a high-efficiency circulator designed for heating systems. It offers faster installation, smarter setup and troubleshooting, higher energy savings and fewer call-backs compared to other pumps.
ALPHA is a high-efficiency circulator fitted with an electronically commutated motor and designed for circulating liquids in heating systems. The pump features the highest energy rating on the market.
ALPHA is designed with intelligent controls featuring a constant-pressure, proportional-pressure and constant-speed curve, each with three speed settings as well as an AUTOADAPT setting, removing the need to manually select the pump setpoint.
The new toolless, removeable power connector results in fast and easy installation. Fewer callbacks can be expected due to its robust startup, self-venting ability and dry-running protection. A system air detection and venting mode can be activated through the Grundfos Go app.
The Grundfos GO app also provides the ability to conveniently troubleshoot your system through the event log, run guided setup, set custom control modes and run firmware updates. Historical trend data for flow, head, media temperature and on-cycle durations is also available through the app.
A terminal box with conduit connections is provided for power connection.
