Onyx GPD25-6SQ 130 Bronze Hot Water Circulating Pump

The Onyx 15-60 (130) Bronze Circulating Pump is a type of circulator pump designed primarily for heating and plumbing systems. It is used to circulate water or other fluids through the system, ensuring that heat is evenly distributed across radiators or other heating components. 

Key Features:

• Pump Type: This is a bronze circulator pump, which means the body of the pump is made of bronze. This material is corrosion-resistant, making it particularly suitable for systems that circulate domestic hot water.
• Model Number: The 15-60 (130) part of the model refers to the pump’s flow rate, head capacity and the pipe centres, 15 refers to the nominal size of the pump's inlet and outlet, which is 1.1/2 inch. 60 refers to the pump's head capacity in feet, meaning it can effectively push water through a system with a head pressure of up to 60 feet. 130 means the pump is 130mm from connection to connection.
• Bronze Construction: Bronze is used because it is resistant to rust and corrosion, making it ideal for applications in water circulation, especially in systems like hydronic heating (radiator-based systems) or cooling systems that may encounter mineral buildup over time.
• Applications: These pumps are often used in home heating systems, including underfloor heating, hot water recirculation, and other hydronic systems. They can also be used in cooling applications where there’s a need for fluid movement.
• Energy Efficiency: Modern circulating pumps like the Onyx 15-60 (130) are designed to be energy-efficient, using advanced motor technology that adjusts the speed of the pump to match the system's requirements, reducing energy consumption while maintaining effective circulation.
• Durability: The bronze construction makes the pump durable, ideal for long-term use in heating or hot water systems.
