Grundfos 99490916 Pump
The Grundfos 99490916 ALPHA2 26-99F is a high-efficiency variable speed circulator designed for closed-loop hydronic and radiant heating systems. This model features a rugged cast iron pump housing and advanced ECM motor technology, providing up to 85% energy savings compared to standard fixed-speed pumps. Technicians can leverage the AUTOADAPT functionality, which automatically analyzes system requirements and find the optimal duty point to match shifting demand. With a maximum head of 32 feet and a flow range up to 26 GPM, this pump is a direct replacement for the legacy UPS26-99FC. The magnetite resistant design and rotatable terminal box simplify integration into existing 115V configurations. Equipped with eight intelligent control modes, including three proportional and three constant pressure curves, the Grundfos ALPHA2 circulator offers the precision required for complex zoned applications.
Key Benefits- AUTOADAPT logic continuously optimizes pump performance to minimize energy consumption while maintaining contractor-grade reliability.
- Features a high-efficiency ECM motor with permanent magnet technology to prevent rotor locking from system debris.
- Integrated magnetite resistance protects internal components from iron oxide buildup common in older hydronic loops.
- User-friendly interface with LED indicators provides real-time diagnostics and clear visibility of current pump settings.
- Compact 6-1/2 inch port-to-port length and a built-in removable check valve ensure straightforward installation in tight mechanical rooms.
Is the ALPHA2 26-99F compatible with wireless balancing tools?
Yes, this model supports hydronic system balancing via the Grundfos GO Balance app when used with the appropriate mobile interface, allowing for faster commissioning.
Can this pump be used in open-loop potable water systems?
No, the 99490916 model features a cast iron volute intended strictly for closed-loop heating applications to prevent corrosion. For domestic hot water, a stainless steel variant is required.
What are the power requirements for this circulator?
The unit operates on a standard 115V single-phase power supply and draws a maximum of 1.7 Amps, making it compatible with most residential and light commercial controllers.
