Description
Grundfos UPS 32-160 F Wet Rotor Circulator Pump (SKU 96402733)
The Grundfos UPS 32-160 F is a high-performance, three-speed wet rotor circulator pump engineered for demanding hydronic heating and cooling applications. With a robust cast iron housing paired with a corrosion-resistant stainless steel impeller, this pump delivers reliable, long-lasting performance in closed-loop hydronic systems. The integrated wet rotor design eliminates the need for external bearings and shaft seals, reducing maintenance requirements and extending service life.
Key Features
- Model: UPS 32-160 F
- Motor Output: 3/4 HP
- Voltage: 230 VAC, Single Phase
- Speed: 3450 RPM, 3-Speed Operation
- Housing Material: Cast Iron for superior durability and pressure resistance
- Impeller Material: Stainless Steel for corrosion resistance and long service life
- Design: Wet Rotor — motor rotor runs in the pumped fluid, eliminating shaft seals and external bearings
- Connections: 1-1/2″ Non-ANSI 2-Bolt Flange Suction and Discharge
Performance & Application
The three-speed selector allows system balancing and energy optimization across a wide range of hydronic applications. The non-ANSI 2-bolt flange connections on both suction and discharge ports simplify installation and integration into existing piping systems. This pump is ideally suited for:
- Hydronic heating and radiant floor systems
- Hot water recirculation
- Commercial and light industrial HVAC systems
- Boiler and chiller loop circulation
Construction & Design Benefits
- Cast iron body provides strength and long-term pressure integrity
- Stainless steel impeller resists corrosion in treated water systems
- Wet rotor design: no mechanical shaft seal, reducing leak points and maintenance
- Compact, in-line design for easy installation in tight mechanical spaces
- Three selectable speed settings for precise flow and system balancing
