Grundfos 99287256 Pump
The Grundfos 99287256 ALPHA1 15-55F is a high-efficiency circulator pump designed for precision fluid handling in residential heating systems, including hydronic radiant heating and baseboard applications. Operating at 115V with a robust 1/16HP motor, this cast iron pump utilizes a permanent magnet motor and frequency converter to automatically adjust performance to meet system demand. This model is a direct drop-in replacement for the discontinued maintenance-heavy pumps, offering a wide pump head range up to 17 feet and a maximum flow rate of 21 GPM. Featuring an ECM motor technology, it significantly reduces power consumption compared to standard three-speed circulators. The integrated LED display provides real-time power consumption in watts and flow indicators, allowing technicians to verify system performance during commissioning. With a fluid temperature range of 36°F to 230°F, this variable speed circulator ensures reliable operation in high-temperature closed-loop systems.
Key Benefits:- Energy Efficiency: Integrated frequency converter allows for proportional pressure control, significantly lowering operational overhead.
- Ease of Installation: Standard 2-bolt flange connection and a compact design facilitate pump replacement in tight mechanical rooms.
- Intuitive Control: Simple one-button interface allows for toggling between three constant-pressure curves and three constant-speed curves.
- System Protection: Internal electronics provide thermal protection and high starting torque to prevent impeller seizing after seasonal shutdowns.
What is the difference between the ALPHA1 and the ALPHA2?
The Grundfos ALPHA1 15-55F focuses on essential constant pressure and constant speed modes for hydronic systems, whereas the ALPHA2 includes advanced features like AUTOADAPT and hydronic balancing capabilities.
Can this pump be used for domestic hot water recirculation?
As this specific model features a cast iron housing, it is intended only for closed-loop heating systems. For open-loop or potable water applications, a stainless steel housing is required.
Does this model include the terminal box?
Yes, this Grundfos circulator comes with a standard terminal box for hardwired electrical connections in 115V applications.
