Avansa 25/6/130

Product detailed description

This circulation pump is commonly used in residential and light industrial applications where controlled water flow is required. It is suitable for installation in central heating systems, domestic water supply lines, and air conditioning circuits. The pump is designed to operate with a range of water temperatures and is often integrated into systems where variable flow rates are necessary for optimal performance. Installers should ensure that the pump is installed in a location that allows for easy access for maintenance and inspection.

The Avansa 25/6/130 is particularly suited for systems where the pumped medium may vary in temperature from -10°C to +110°C. It is commonly used in applications involving cold water, heating systems, and air conditioning. The pump is not recommended for use in aggressive chemical environments or where the medium contains high concentrations of suspended solids. The compact dimensions and lightweight design allow for flexible installation in tight spaces such as utility rooms or mechanical areas.

Technical parameters

Installation and connection

Installation should be carried out by a qualified technician. The pump should be mounted on a stable surface to prevent vibration and ensure proper alignment with the pipework. The 6/4" connection dimensions require appropriate fittings to ensure a secure and leak-free connection. The inlet and outlet ports are 25mm in diameter and should be connected using compatible pipe threads or flanges. It is important to verify that the pump is installed in the correct orientation to avoid air binding and cavitation. A non-return valve should be installed downstream to prevent backflow when the pump is not operating.

Common installation mistakes include incorrect orientation of the pump, failure to secure the mounting, and neglecting to bleed the system after installation. These can lead to reduced efficiency, premature wear, and potential system failure. The pump should be installed in a location that allows for easy access to the terminal block and control switch for speed adjustment.

Compatibility and accessories

The Avansa 25/6/130 is compatible with standard domestic and industrial water systems. It is often used in conjunction with heating boilers, water heaters, and HVAC units. Additional accessories such as pressure gauges, flow meters, and control panels may be required for monitoring and system integration. The pump is not suitable for use in systems with high chemical content or where the medium is abrasive.

Technical background for designers

The pump operates using an asynchronous bipolar motor that does not require overload protection. The motor is enclosed in a cast iron housing with plastic components to reduce weight and improve corrosion resistance. The three-speed operation is controlled via a switch on the terminal block, allowing the pump to be adjusted to the hydraulic characteristics of the system. The IP44 rating ensures that the pump is protected against dust and splashing water, making it suitable for indoor use. The insulation class FH indicates that the motor is designed to operate at higher temperatures without degradation of performance.

The pump is designed to handle a wide range of temperatures and is suitable for use in systems where the medium may vary from cold to hot water. The materials used in the construction of the pump ensure durability and resistance to corrosion. The compact size and lightweight design allow for easy integration into existing systems without requiring major modifications. The pump is suitable for use in both residential and light industrial applications where a reliable and adjustable flow rate is required.

Service and operation

Regular inspection of the pump is recommended to ensure continued performance and longevity. The terminal block and control switch should be checked for signs of wear or damage. The pump should be monitored for unusual noise or vibration, which may indicate misalignment or bearing wear. The pump does not require scheduled service intervals, but it is advisable to inspect the system periodically for leaks, blockages, and correct flow rates. If the pump is to be stored for an extended period, it should be drained and protected against corrosion.
