Avansa 25/8/180

Product detailed description

This circulating pump is commonly used in residential and commercial heating systems, domestic water distribution, and industrial circulation applications. It is installed in closed-loop systems where controlled water flow is required, such as in underfloor heating, radiators, and air conditioning units. The compact dimensions and lightweight design allow for easy integration into tight spaces, while the three-speed control ensures adaptability to varying system demands. The pump is suitable for use in environments where the temperature of the pumped medium ranges from -10°C to +110°C, making it suitable for both heating and cooling applications. The IP44 rating ensures the pump is protected against dust and water spray, but it is not suitable for outdoor or submerged installation.

When selecting this model, installers should consider the required flow rate, system pressure, and the distance between the inlet and outlet. The pump is designed for use with water-based media and is not suitable for aggressive or abrasive fluids. The asynchronous motor does not require overload protection, simplifying the electrical connection and reducing the need for additional components. The pump is connected via 6/4" threaded ports and is compatible with standard pipe systems. The three-speed switch allows for manual adjustment of the pump’s performance to match the system’s hydraulic requirements.

Technical parameters

The technical parameters are essential for correct sizing and system integration. The maximum working pressure of 10 bar ensures the pump can handle typical domestic and light industrial systems. The 115 l/min maximum flow rate and 8m head are key for determining whether the pump can meet the system’s hydraulic requirements. The IP44 rating indicates the pump is suitable for indoor use only, and the temperature range of -10°C to +110°C allows for use in both heating and cooling systems. The 230V asynchronous motor with three-speed control provides flexibility in operation without the need for external overload protection.

Installation and connection

Installation of the AVANSA 25/8/180 should be carried out in accordance with standard plumbing and electrical codes. The pump is connected using 6/4" threaded ports, which are standard for many pipe systems. The inlet and outlet ports are aligned with a 180 mm distance between them, which should be considered when planning the layout to ensure sufficient clearance. The pump should be mounted on a stable, level surface to prevent vibration and misalignment. The three-speed switch is located on the terminal block and should be accessible for manual adjustment after installation. Before energising the pump, ensure the electrical supply matches the 230V rating and that the motor is correctly wired. A common mistake is not securing the pump adequately, which can lead to vibration and premature wear. Always check the alignment of the inlet and outlet pipes to prevent stress on the pump housing.

Compatibility and accessories

The AVANSA 25/8/180 is compatible with standard water-based systems and can be integrated into both residential and industrial applications. It is suitable for use with cast iron or plastic pipework and is compatible with systems operating within the specified temperature range. To ensure a secure and leak-free connection, it is recommended to use appropriate sealing materials such as PTFE tape or gaskets. A suitable mounting bracket may also be required to secure the pump to the wall or base. This accessory is particularly useful when connecting the pump to non-standard or older piping systems.

Technical background for designers

The AVANSA 25/8/180 operates on the principle of a centrifugal pump, where the impeller generates a pressure differential to move the fluid through the system. The asynchronous motor provides consistent torque and is designed for continuous operation without the need for overload protection. The pump body is constructed from cast aluminium, which offers good thermal conductivity and resistance to corrosion in water-based environments. The plastic components used in the pump are selected for their durability and resistance to thermal expansion. The pump is designed to integrate into closed-loop systems, where the flow rate and pressure can be adjusted using the three-speed switch. The service life of the pump is influenced by the quality of the installation, the cleanliness of the pumped medium, and the frequency of maintenance. Proper alignment and secure mounting are essential to prevent mechanical stress and vibration, which can reduce efficiency and lead to premature failure.

Service and operation

Regular inspection of the pump is recommended to ensure continued performance and to identify potential issues before they become critical. The pump should be checked for signs of vibration, unusual noise, or leaks at the connections. The three-speed switch should be tested to confirm that all settings are functioning correctly. The motor should be kept free from dust and debris to prevent overheating. No specific service intervals are provided in the technical data, but it is advisable to perform a visual inspection at least once a year. If the pump is used in a system with high particulate content, more frequent cleaning of the inlet filter may be necessary. The pump should be disconnected from the power supply before any maintenance is carried out to ensure safety. If the pump fails to operate or shows signs of reduced performance, the electrical connections should be checked, and the motor should be tested for continuity.

Frequently asked questions

Can the AVANSA 25/8/180 be used in a system with a temperature above 110°C?
No, the maximum temperature of the pumped medium is specified as +110°C. Exceeding this limit may damage the pump components and reduce its service life.

Is the pump suitable for outdoor installation?
No, the IP44 rating provides protection against dust and water spray but is not sufficient for outdoor use. The pump is designed for indoor installation only.

Can the pump be controlled using an external thermostat or controller?
No, the pump features a built-in three-speed switch for manual adjustment. It does not have a control input for external thermostats or controllers.

What is the maximum distance between the inlet and outlet ports?
The distance between the inlet and outlet ports is fixed at 180 mm. This should be considered when planning the installation to ensure sufficient clearance.
