Grundfos 52722370 Pump

The Grundfos 52722370, model UP43-75BF, is a high-performance, single-speed bronze circulator pump engineered for demanding commercial and residential hydronic systems. Featuring a 1/6 HP motor operating at 115V, this wet rotor circulator is specifically designed for hot water recirculation and open-loop heating applications where corrosion resistance is critical. The robust bronze housing ensures longevity in oxygen-rich potable water systems, while the maintenance-free design utilizes the pumped liquid to lubricate the ceramic bearings, eliminating the need for external oiling. With a maximum flow rate of 41 GPM and a maximum head of 24.9 feet, this pump provides the consistent pressure required for fan coil heating and large-scale domestic water systems. The GF 40/43 flange connection (1-1/2") allows for seamless professional installation in standard piping configurations, maintaining system integrity under operating pressures up to 145 PSI and fluid temperatures up to 230°F.

Key Benefits

  • Corrosion-Resistant Housing: The bronze pump housing prevents oxidative wear, making it the industry standard for potable water systems.
  • Whisper-Quiet Operation: The wet rotor design and canned rotor motor minimize vibration and sound, ideal for noise-sensitive installations.
  • High-Efficiency Performance: Features a composite PES impeller and stainless steel rotor can to maximize hydraulic efficiency and reduce energy consumption.
  • Simplified Maintenance: The maintenance-free, seal-less construction prevents common leak points associated with mechanical seals.
  • Thermal Protection: Includes built-in internal motor protection to ensure operational stability under high ambient temperatures.

Common Questions

What are the primary applications for the UP43-75BF?
This model is frequently used by contractors for hydronic heating, domestic hot water recirculation, and radiant floor heating systems that require a 115V single-phase power supply.

What flange size is compatible with the Grundfos 52722370?
The pump utilizes a 1-1/2" GF 40/43 flange connection. Note that flanges are typically sold separately to match the specific pipe diameter of your installation.

Can this pump be used in chilled water systems?
Yes, the UP43-75BF is rated for a liquid temperature range of 35.6°F to 230°F, making it suitable for both heating and cooling circulation tasks.
