Product Overview
The Grundfos UP15-14 BA PM is a high-efficiency, wet-rotor circulator pump engineered for domestic and light commercial hot water recirculation systems. As a member of the Grundfos UP series, this pump operates on a canned-motor (wet-rotor) principle, where the rotor is fully encapsulated and lubricated by the pumped medium, eliminating the need for mechanical shaft seals and external lubrication. The “BA” designation indicates built-in line-cord electrical connection, while “PM” signifies a permanent magnet motor design that delivers exceptional energy efficiency compared to conventional induction-motor circulators. This pump is specifically designed to maintain consistent hot water delivery at fixtures, reduce water waste, and improve system response in closed-loop potable water and hydronic heating circuits.

Engineering Features & Advantages
- Precision Performance: The permanent magnet motor and wet-rotor design deliver stable, low-noise circulation with minimal vibration, ensuring consistent hot water delivery without the pulsation or cavitation risks associated with less refined circulator designs.
- Industrial Reliability: Built for continuous duty in closed-loop potable water and hydronic systems; the absence of shaft seals eliminates leak paths and reduces maintenance intervals significantly.
- Direct Fit Replacement: Exact dimensional and functional compatibility with standard Grundfos UP-series mounting footprints, allowing drop-in replacement without piping modifications.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original GRUNDFOS OEM standards, ensuring drop-in replacement without modification to existing manifolds or piping.
