Description
Grundfos UPS 32-160 F Wet Rotor Circulator Pump
The Grundfos UPS 32-160 F (SKU 96402737) is a heavy-duty wet rotor circulator pump engineered for demanding hydronic heating and cooling applications. Combining a robust cast iron housing with a corrosion-resistant stainless steel impeller, this pump delivers reliable, long-lasting performance in commercial and industrial systems. The integrated wet rotor design eliminates the need for external bearings and seals, reducing maintenance requirements and extending service life.
Key Features
- Motor Output: 3/4 HP for powerful, consistent flow performance
- Voltage: 460Vac — designed for three-phase commercial power systems
- Phase: Three-phase motor for smooth, efficient operation
- Speed: 2-speed operation at 3450 RPM for flexible system balancing and energy management
- Construction: Cast iron housing for durability and pressure resistance
- Impeller: Stainless steel impeller for corrosion resistance and long service life
- Design: Wet rotor — pump medium lubricates the rotor, eliminating external seals and bearings
- Connections: 1-1/2″ non-ANSI 2-bolt flange suction and discharge connections for straightforward installation
- Model: UPS 32-160 F
Construction & Design
The UPS 32-160 F features a cast iron volute and housing that withstands the rigors of high-pressure hydronic systems, while the stainless steel impeller resists corrosion from system water and treatment chemicals. The wet rotor configuration means the circulating fluid itself cools and lubricates the motor, resulting in quieter operation and reduced wear compared to dry rotor alternatives.
2-Speed Flexibility
With two selectable operating speeds, the UPS 32-160 F allows system designers and technicians to fine-tune flow rates to match system demand. This capability supports energy savings during partial-load conditions and provides greater control over hydronic system performance.
Connection Details
Equipped with 1-1/2″ non-ANSI 2-bolt flange connections on both suction and discharge ports, the pump integrates easily into a wide range of piping configurations common in commercial hydronic systems. The flanged connections facilitate quick installation, removal, and servicing.
Typical Applications
- Commercial hydronic heating systems
- Hot water recirculation
- Industrial process cooling and heating loops
- Chilled water distribution systems
- HVAC fan coil and air handler loops
