Grundfos 95906637 Pump
The Grundfos 95906637, also known as the UPS43-100F Super Brute, is a high-performance 3-speed circulator pump engineered for demanding hydronic heating and cooling applications. As a veteran-grade cast iron pump, this unit features a robust 1/3 HP wet-rotor motor designed for 230V operations, making it a staple for commercial and large-scale residential closed-loop systems. The integrated 3-speed switch allows technicians to precisely match the pump's curve to the system's head requirements, significantly reducing flow noise and energy consumption. This flanged circulator utilizes a standard 2-bolt flange connection (GF 40/43), ensuring seamless integration into existing HVAC piping. With a maximum head of 31 feet and a peak flow rate of 65 GPM, it provides the versatility needed for diverse terminal units, from radiant manifolds to air handlers. Its canned-rotor design eliminates the need for mechanical seals, providing whisper-quiet, maintenance-free performance even in continuous-duty cycles. For professional installers, the UPS43-100F is the reliable choice for minimizing callbacks and optimizing system pressure.
Key Benefits- Selectable Performance: Integrated 3-speed motor allows for field-adjustable flow to meet specific system resistance, eliminating the need to stock multiple pump sizes.
- Heavy-Duty Construction: The cast iron housing and composite impeller are built to withstand high-temperature hydronic fluid up to 230°F.
- Quiet Operation: Ceramic bearings and wet-rotor technology ensure extremely low decibel levels, ideal for placement near occupied spaces.
- Technical Versatility: Suitable for both high-flow and high-head applications within closed-loop heating or chilled water systems.
- Streamlined Installation: Compact 8-9/16" port-to-port length and industry-standard flanging allow for rapid drop-in replacement of older circulators.
What is the maximum operating pressure for this pump?
The Grundfos 95906637 is rated for a maximum operating pressure of 145 PSI, making it suitable for high-rise residential or commercial boiler loops.
Can this pump be used in open-loop potable water systems?
No, since this is a cast iron pump, it is strictly intended for closed-loop systems where oxygen is not present to prevent corrosion. For domestic water recirculation, a stainless steel or bronze model is required.
What flange size is required for installation?
This model requires a 1-1/2" cast iron flange set compatible with the GF 40/43 2-bolt mount. Always ensure you have a fresh set of gaskets for a leak-free seal during the swap.
