This UP Series replacement circulating pump, model UP 26-116 F, is a single-speed, wet rotor design intended for use in geothermal flow centers, ground-source and water-source heat pumps, and various hot and chilled water circulation systems. It operates on 230V, single-phase power and delivers up to 37 GPM with a maximum head of 37 feet.The pump utilizes a canned rotor construction, where the pump and motor form an integral unit without a conventional shaft seal, using the pumped liquid for bearing lubrication. Key internal components include a ceramic shaft, carbon axial bearing, and a corrosion-resistant composite impeller, all housed within a durable cast iron casing. Note that this product is typically the pump head only and may ship without the volute.
