UCT 303 and UC 303

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″ sweat union connections. The compact design saves space and the cost associated with purchasing the additional fittings is also a huge labor saving product for the contractor/plumber. The UltraCirc feature is available on the SM 303 and SMT 303 series pumps. The SM 909 series pumps are available for larger plumbing circuits.
