WiseWater Hot Water Recirculating Pump, 3-Speed Stainless Steel Circulator Pump with 3/4'' NPT Adapters, 20ft Head, Ultra-Quiet

The WiseWater hot water recirculating pump is designed for residential and light commercial water circulation applications. The pump features a 304 stainless steel pump head, aluminum alloy housing, full copper motor coil, and PP impeller for stable long-term operation in hot water circulation systems. Suitable applications include domestic hot water recirculation, radiant floor heating systems, hydronic heating loops, industrial equipment cooling circulation, and small boiler water circulation systems. This product has a 1-year warranty against manufacturer's defects and is UL listed. This listing is for the pump (with gaskets) only; flanges and bolts are not included. Product Features 304 Stainless Steel Pump Head The pump head and center screw are manufactured from 304 stainless steel to improve resistance to corrosion and rust in hot water circulation environments. The included brass adapters and rubber gaskets help support stable sealing performance during installation. 3-Speed Adjustable Operation The integrated 3-speed switch allows the pump to operate at different power levels depending on system requirements. Speed Level Power Low 46W Medium 67W High 93W This adjustment helps adapt the pump to different circulation demands in residential or hydronic systems. Stable Water Circulation Performance The pump provides: Maximum head lift: 20 FT (6M) Maximum flow rate: 12.6 GPM The internal rotor is designed for stable operation and continuous circulation performance in closed-loop water systems. Model Number WW-pump-red Power Source Corded Electric Flow Rate 12.6 Gallons Per Minute Maximum Lifting Height 20 Feet Voltage 110 Volts Color Red Material Stainless Steel Product Dimensions 4.95"L x 5.12"W x 4.5"H Item Weight 5.4 Pounds Low Operating Noise The circulating pump operates at approximately 30dB under normal conditions, making it suitable for installation in residential utility rooms, mechanical rooms, or underfloor heating systems where lower operational noise is preferred. Multiple System Applications This circulator pump can be used in: Domestic hot water recirculation systems Hydronic radiant floor heating Closed-loop heating systems Small boiler circulation systems Industrial equipment cooling circulation Water transfer systems requiring continuous circulation Installation Information The pump is designed for inline installation on compatible plumbing systems. Basic installation typically requires: Wrench tools Proper pipeline sealing Matching pipe thread compatibility The included brass adapters help connect the pump to standard residential plumbing systems using 3/4" connections. Professional installation is recommended for complex hydronic or boiler systems. Recommended Applications Domestic Hot Water Recirculation Helps maintain continuous hot water circulation through household plumbing systems. Radiant Floor Heating Suitable for circulating heated water in hydronic underfloor heating loops. Hydronic Heating Systems Can be integrated into closed-loop heating circulation systems. Equipment Cooling Circulation Applicable for light industrial or machine cooling water circulation systems. Maintenance Notes Ensure the pump operates with water in the system before continuous operation. Periodically inspect fittings and gaskets for leakage. Install in accordance with local plumbing and electrical codes. Avoid prolonged dry running conditions. Technical Notes Flow rate and head performance may vary depending on pipe length, system pressure, and installation conditions. Noise levels can vary based on mounting method and surrounding environment. Designed primarily for water circulation applications within compatible temperature and pressure ranges.
