Description
The Grundfos UPS 50-160 F (SKU 96411613) is a high-performance wet rotor circulator pump engineered for demanding hydronic heating and cooling applications. With a robust 1.5 HP motor operating on 230 Vac single-phase power at 3,450 RPM, this pump delivers reliable, efficient fluid circulation across a wide range of commercial and residential systems. The three-speed operation gives installers and system operators the flexibility to fine-tune flow rates to match precise system demands, reducing energy consumption and optimizing comfort.
Built to last, the UPS 50-160 F features a durable cast iron housing paired with a corrosion-resistant stainless steel impeller — a combination that stands up to the rigors of continuous-duty hydronic service. The wet rotor design eliminates the need for external bearings and shaft seals, using the circulated fluid itself for lubrication and cooling. This results in quieter operation, reduced maintenance requirements, and an extended service life.
Connections are made via 2-inch non-ANSI 4-bolt flange suction and discharge ports, ensuring a secure, leak-free installation that integrates seamlessly into standard hydronic piping configurations.
