Description
Grundfos UPS 32-160 F Wet Rotor Circulator Pump (96402736)
The Grundfos UPS 32-160 F is a high-performance, three-phase 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-service-life performance in commercial and industrial systems. Its integrated wet rotor design eliminates the need for external shaft seals and separate lubrication, reducing maintenance requirements and overall system downtime.
Key Features
- Motor Output: 3/4 HP for powerful, efficient fluid circulation
- Voltage: 208–230V AC, Three Phase for compatibility with commercial power supplies
- Speed: 3-speed operation (3,450 RPM) for flexible flow and head adjustment
- Housing: Durable cast iron construction for long-term durability
- Impeller: Stainless steel impeller for corrosion resistance and extended service life
- Design: Wet rotor technology — no external seals or separate lubrication required
- Connections: 1-1/2″ non-ANSI 2-bolt flange suction and discharge connections for straightforward installation
- Model: UPS 32-160 F
Wet Rotor Advantage
The wet rotor design means the motor’s rotor operates directly within the pumped fluid, using it as both coolant and lubricant. This eliminates mechanical shaft seals — a common failure point in traditional pump designs — resulting in a quieter, virtually maintenance-free circulator that is ideal for closed-loop hydronic systems.
3-Speed Flexibility
With three selectable speed settings at 3,450 RPM, the UPS 32-160 F allows installers and system operators to fine-tune flow rates and system pressure to match actual load requirements. This flexibility supports energy efficiency and optimized system performance across varying demand conditions.
Typical Applications
- Commercial hydronic heating systems
- Chilled water distribution loops
- Industrial process cooling and heating circuits
- Hot water recirculation in large commercial buildings
- Boiler and heat exchanger circulation
