Description
The WiseWater hot water recirculating pump is designed for water circulation in closed-loop heating systems. It is suitable for residential and light commercial applications such as hydronic radiant heating, boiler systems, solar water heating, domestic hot water circulation, and other water-based heating systems.
The pump is equipped with a three-speed manual control system, allowing adjustment of operating power according to system requirements. The three selectable power levels are 55W, 90W, and 130W, with a maximum flow rate of 13 GPM and a maximum head of 24 ft.
The pump is designed for continuous water circulation in heating systems. The wet rotor structure eliminates the need for mechanical seal replacement under normal operating conditions.
The system includes a three-speed manual control switch for adjusting pump output. External controllers are not required for basic operation.
The circulation pump is used to support water movement in heating systems and maintain system circulation. It can be installed in domestic hot water tanks, manifolds, heat exchangers, and other hydronic system components.
The product is supplied with standard installation fittings including flanges, gaskets, and fasteners to support basic installation requirements.

Three-Speed Operation
The pump features a manual 3-speed switch for operation control:
- Speed I: 55W
- Speed II: 90W
- Speed III: 130W
The speed setting can be selected based on system resistance and flow demand. The maximum operating flow rate is 13 GPM.
Installation and Connection
The pump is designed for standard piping installation using 3/4" FNPT flanges.
Each unit includes installation accessories:
- 2 × 3/4" FNPT flanges
- 2 × gaskets
- 4 × bolts
- 4 × nuts
Installation can be completed using standard tools by connecting the flanges to compatible piping systems.
Pump Structure and Materials
The pump adopts a wet rotor circulation structure, where the pumped fluid provides lubrication for internal components during operation.
Key components include:
- Cast iron pump housing and pump head
- PES impeller for stable operation under temperature conditions
- Ceramic bearing for corrosion resistance in water circulation applications
- Copper winding motor for standard 110V operation
Maximum operating conditions:
- Maximum pressure: 145 psi (10 bar)
- Maximum temperature: 230°F (110°C)
Application Scope
This circulation pump is suitable for water circulation in closed-loop systems, including:
- Hydronic radiant floor heating systems
- Boiler circulation systems
- Solar water heating systems
- Domestic hot water recirculation systems
- Sidearm heat exchangers
- Heating manifolds
- Snow melting systems
- Air and water heating circulation systems
- Swimming pool heating loops (indirect systems)
It is intended for clean water circulation in compatible heating applications.
