Wilo-Yonos MAXO 30/0,5-7 PN10 circulation pump 2120642

High-efficiency and versatile circulation pump

Wilo-Yonos MAXO 30/0.5-7 PN10 circulation pump is an advanced solution designed for heating, cooling, and domestic hot water circulation systems. The device is characterized by high energy efficiency, reliability, and the ability to smoothly adjust performance. The construction based on a cast iron housing (GG 20 / GJL-200) ensures durability and corrosion resistance, and a wide range of operating temperatures from -20°C to 110°C makes it a universal choice for various installations.

Construction and characteristic features

The Wilo-Yonos MAXO pump is designed for easy installation and operation. It has threaded inlet and outlet connections with a diameter of 2 inches (50 mm) compliant with ISO 228-1, which facilitates integration with existing installations. The built-in speed controller allows for precise adjustment of the pump's performance to current needs, minimizing energy consumption. The use of an ECM motor guarantees very low power consumption – even 5W in standby mode – and a high energy efficiency index (EEI) of 0.2. Additionally, the pump is equipped with motor protection and an automatic venting function for the impeller chamber.

• Wide temperature range: Operation in the range of -20°C to 110°C allows the pump to be used in both heating and cooling installations.
• High energy efficiency: Energy efficiency class A+++ and low EEI = 0.2 minimize operating costs.
• Smooth performance adjustment: Stepless speed control allows for precise adjustment of the pump to current system needs.
• Durable construction: Cast iron housing (GG 20 / GJL-200) provides corrosion resistance and long device life.
• Simple installation and operation: Threaded connections and an intuitive control panel facilitate installation and configuration of the pump.
• Automatic functions: Automatic venting of the impeller chamber and return to settings after a power failure increase user comfort.
• Motor protection: Integrated full motor protection protects the device from damage.

Technical parameters and application

The Wilo-Yonos MAXO 30/0.5-7 PN10 pump is characterized by a maximum flow rate of 8.149 m³/h and a head of up to 7.544 m. It is designed to operate in installations with a maximum working pressure of 10 bar and an ambient temperature from -20°C to 40°C. Single-phase 230 V / 50–60 Hz power supply and IPX4D protection class ensure safe and reliable operation of the device in typical installation conditions. The pump finds application in:

• Central heating systems: Circulation of heating water in residential and commercial buildings.
• Domestic hot water systems: Ensuring continuous circulation of hot water in sanitary installations.
• Air conditioning and cooling systems: Circulation of cooling medium in air conditioning systems.
• Industrial installations: Circulation of process water in industrial processes.
