- 460Vac, three-phase power supply for commercial and industrial compatibility
- 3,450 RPM motor speed ensures efficient, high-head performance
- 2-speed operation allows system optimization and energy management across varying load conditions
- Wet rotor design eliminates the need for external bearings and seals, reducing maintenance requirements
- Cast iron housing provides exceptional durability and pressure resistance
- Stainless steel impeller offers superior corrosion resistance for extended service life
- 2″ non-ANSI 4-bolt flange suction and discharge connections for straightforward installation and system integration
Construction & Design
The UPS 50-160 F features a wet rotor motor configuration where the rotor operates directly in the pumped fluid, providing inherent lubrication and cooling without the need for mechanical seals or external bearing maintenance. The cast iron volute and housing are built to withstand the rigors of continuous commercial operation, while the stainless steel impeller resists corrosion from system water and treatment chemicals.
Applications
- Commercial and industrial hydronic heating systems
- Chilled water distribution and cooling loops
- Large-scale building HVAC circulation
- Process heating and cooling circuits
- Hot water recirculation in multi-zone systems
