The UltraCirc design incorporates a ball valve on the inlet side of the pump, a spring check valve on the discharge side of the pump, and 1/2-inch sweat union connections. The magnetically driven rotor/impeller, which is the only moving part in the pump, eliminates the need for a shaft, says the company. According to the manufacturer, the compact design saves space, eliminates costs associated with purchasing the additional components, and offers a labor savings average of over one hour for the installer. With fewer moving parts, the pump is virtually maintenance-free, ensuring longer operating life than any other water circulation pump, claims the company.
