Construction & Design

The UPS 50-80/2 F features a wet rotor motor configuration where the rotor runs directly in the pumped fluid, providing self-lubrication and eliminating mechanical seals. This design significantly reduces noise levels and maintenance intervals compared to traditional dry rotor pumps. The cast iron body withstands high operating pressures and temperatures typical of hydronic systems, while the stainless steel impeller ensures compatibility with treated system water.
