Grundfos UPS 40-80/2 F Wet Rotor Circulator Pump
The Grundfos 96402762 (Model UPS 40-80/2 F) is a high-performance wet rotor circulator pump engineered for reliable hydronic heating and cooling applications. With a robust cast iron housing and a corrosion-resistant stainless steel impeller, this pump delivers lasting durability and efficient fluid transfer across a wide range of system configurations.
Key Features
- 3/4 HP motor output for dependable circulation performance
- 115V AC, single-phase power supply for standard residential and light commercial electrical systems
- 3450 RPM operating speed for efficient fluid movement
- 3-speed operation allows system balancing and energy optimization
- Wet rotor design — motor rotor runs in the pumped fluid, eliminating the need for external shaft seals and reducing maintenance requirements
- Cast iron housing for rugged, long-lasting construction
- Stainless steel impeller for corrosion resistance and extended service life
- 1-1/2″ non-ANSI 2-bolt flange suction and discharge connections for straightforward installation and system integration
Construction & Design
The wet rotor circulator design integrates the motor rotor directly into the fluid stream, which provides self-lubrication and eliminates mechanical shaft seals — a common source of leaks and maintenance issues in traditional pump designs. The cast iron body withstands the demands of pressurized hydronic systems, while the stainless steel impeller resists corrosion from system water and additives.
Applications
- Hydronic heating systems
- Hot water recirculation
- Radiant floor heating loops
