Grundfos 95906636 Pump
The Grundfos 95906636 is a professional-grade UPS43-100F 115V circulator pump built for high-demand hydronic heating and cooling systems. This cast iron circulator pump features a versatile 3-speed motor, allowing technicians to fine-tune the flow rate and head pressure to match specific system requirements, optimizing energy efficiency and performance. Engineered with a wet-rotor design, the UPS43-100F operates with a canned rotor where the pump and motor form an integral unit without a shaft seal, ensuring near-silent, leak-proof operation and minimal maintenance. With a maximum flow of 65 GPM and a max head of 31 feet, it effectively manages medium-to-large residential and light commercial loops. The 2-bolt flange connection and quick-connect terminals simplify field installation, while the composite PES impeller and ceramic shaft provide superior corrosion resistance in diverse fluid environments. This reliable HVAC circulator pump is rated for fluid temperatures up to 230°F and maximum system pressures of 145 PSI, making it a staple for veteran contractors.
Key Benefits- 3-Speed Versatility: Adjustable performance settings (Low/Medium/High) to meet varying system head and flow demands.
- Canned Rotor Design: Eliminates the need for mechanical seals, reducing leak points and ensuring whisper-quiet operation.
- Internal Motor Protection: Built-in thermal protection handles potential overloads without requiring additional external starters.
- Field Reliability: Features ceramic radial bearings and a stainless steel rotor can for extended service life in taxing hydronic loops.
- Installation Ready: Standard 2-bolt flange housing and 1-1/2 inch connection size for straightforward integration into existing piping.
What is the maximum fluid temperature for the UPS43-100F?
This pump is designed to handle liquid temperatures ranging from 36°F to 230°F, making it suitable for both radiant heating and air conditioning applications.
Is this pump compatible with glycol mixtures?
Yes, it is rated for use with water and water/glycol mixtures up to a 50/50 concentration, typical in closed-loop hydronic systems.
Does the 95906636 include the flanges?
No, the cast iron flange set (GF 40/43) is typically sold separately and is required to complete the installation to the piping system.
