Avansa 25/6/180

Product detailed description

Circulation pumps are essential components in heating and water supply systems, ensuring even distribution of fluids through pipes. The AVANSA 25/6/180 is designed for use in domestic and industrial applications where reliable and continuous fluid movement is required. It is commonly found in central heating systems, underfloor heating, and water circulation loops in larger buildings. The pump operates efficiently within a wide temperature range and is suitable for both low and high-pressure environments. Installers should consider the pump’s dimensions and mounting requirements when planning the layout of the system. Proper alignment and secure mounting are essential for long-term performance and noise reduction.

Technical parameters

Installation and connection

The AVANSA 25/6/180 has DN 25 inlet and outlet connections with 6/4 inch thread sizes. Before installation, ensure the pipeline is clean and free from debris that could damage the internal components. The pump must be mounted on a stable surface to prevent vibration and wear. The distance between the suction and discharge ports is 180 mm, which should be considered when aligning the pump with the piping system. Common installation errors include incorrect orientation of the pump, insufficient support for the piping, and failure to bleed air from the system after installation. Always verify the electrical connections and insulation class FH before energising the unit.

Compatibility and accessories

This pump is compatible with standard water-based systems operating at 230 V. Additional components such as pressure sensors, control panels, or isolation valves may be required depending on the system configuration. Accessories like mounting brackets, gaskets, and sealing compounds should be sourced separately. For larger installations, multiple units can be integrated into a single system provided they are correctly sized and balanced. Always refer to the manufacturer’s guidelines for recommended combinations and accessory specifications.

Technical background for designers

The pump operates using an asynchronous three-speed motor that does not require overload protection. The cast iron and plastic construction provides durability and resistance to corrosion. The motor’s thermal insulation class FH ensures it can handle extended operation under varying load conditions. Integration into the system requires consideration of the pump’s flow and pressure characteristics to avoid overloading the circuit or causing cavitation. The pump’s compact dimensions (13.5 x 19.5 x 14.5 cm) make it suitable for tight spaces, while the weight of 2.8 kg ensures it can be mounted securely without additional reinforcement.

Service and operation

Regular inspection of the pump’s electrical connections and mechanical integrity is recommended to maintain optimal performance. Check for signs of wear on the impeller and seals, and ensure the motor remains free from dust and moisture. The pump does not require scheduled maintenance intervals, but periodic checks for unusual noise or vibration are advisable. If the pump is to be operated in extreme temperatures, verify that the sealing materials are compatible with the expected range of -10 to +110 °C. Always follow the manufacturer’s recommendations for troubleshooting and repair procedures.

Frequently asked questions

Can the AVANSA 25/6/180 be used in a closed-loop heating system?
Yes, the pump is suitable for closed-loop systems as long as the operating pressure and temperature remain within the specified limits.

Is the pump compatible with variable speed controllers?
It has three fixed-speed settings and is not designed for use with external variable speed controllers.

What is the maximum allowable temperature of the pumped medium?
The pump is rated for media temperatures up to +110 °C, making it suitable for hot water and heating systems.

How is the pump controlled during installation?
The pump is controlled via a dedicated switch mounted on the terminal block, allowing for manual speed selection based on system requirements.
