Avansa 32/8/180

Product detailed description

This circulating pump is commonly used in residential and light industrial water distribution systems where controlled flow and pressure are required. It is suitable for applications such as central heating, domestic water circulation, and air conditioning systems. The pump is designed for installation in mechanical rooms, boiler houses, or utility areas where it can be integrated into closed-loop systems. The compact dimensions and lightweight construction make it suitable for tight spaces, while the IP44 rating ensures safe operation in environments with limited exposure to moisture.

Its three-speed operation allows for fine-tuning of flow rates to match the system's demand, making it adaptable to a range of system configurations. The asynchronous motor does not require overload protection, simplifying electrical integration. The pump is intended for use with water or water-based fluids within the temperature range of -10°C to +110°C. The distance between the suction and discharge ports is 180 mm, which is important for ensuring correct alignment during installation.

The pump's maximum working pressure of 10 bar and 8m head make it suitable for systems requiring moderate pressure and elevation. The DN32 connections and 2" thread size are standard for many plumbing and heating systems. The three-speed motor allows for flow rate adjustment, and the IP44 rating ensures protection against dust and splashing water. These parameters are essential for proper sizing and system compatibility.Installation and connection The pump should be installed in a stable, level position to ensure proper operation. The suction and discharge ports are threaded in 2" size, requiring compatible pipe fittings. A minimum clearance around the pump is recommended to allow for maintenance and inspection. The distance between the suction and discharge ports is 180 mm, so the piping layout must accommodate this to prevent misalignment and stress on the connections. Before commissioning, the installer should verify that the electrical supply matches the 230 V requirement and that the motor power (150/210/270 W) is appropriate for the intended speed setting. The speed adjustment switch is mounted on the terminal block and must be configured according to the system's hydraulic needs. Common installation errors include incorrect orientation of the pump, improper support for the pipework, and failure to align the ports correctly, which can lead to vibration and premature wear.

Compatibility and accessories

The pump is compatible with standard DN32 threaded fittings and 2" pipe systems. It is suitable for use with closed-loop heating systems, domestic water circulation, and industrial circulators. For proper system integration, it is recommended to install a non-return valve downstream of the pump to prevent backflow and a pressure gauge to monitor system performance. A thermal expansion vessel may also be required in closed systems to accommodate thermal expansion of the fluid.

Technical background for designers

The pump operates on a three-speed asynchronous motor, which provides variable flow rates without the need for external overload protection. The cast iron and plastic components offer good mechanical strength and resistance to corrosion in water-based environments. The IP44 rating ensures that the pump can operate in dry and damp locations, but it is not suitable for fully submerged or high-pressure water exposure. The motor insulation class FH allows for operation in environments with elevated temperatures, making it suitable for heating systems. The pump's performance is influenced by the viscosity and temperature of the pumped medium, as well as the condition of the internal components. Regular inspection of the pump's mechanical seal and bearings is important for maintaining efficiency and preventing leaks.

Service and operation

The pump requires minimal maintenance, but regular checks should be performed to ensure proper operation. The motor and pump casing should be inspected for signs of wear or damage, and the electrical connections should be verified for tightness and insulation integrity. The pump should be tested under load to confirm that the selected speed setting provides the required flow rate and pressure. The pump should be switched off during maintenance or when the system is not in use to prevent unnecessary wear. The operating temperature of the pumped medium should be within the specified range of -10°C to +110°C to avoid damage to the pump components. No specific service intervals are provided in the technical data, but the pump should be inspected periodically as part of routine system maintenance.

Frequently asked questions

Can the pump be used in a closed-loop heating system?
Yes, the pump is suitable for use in closed-loop heating systems where it can provide circulation for radiators or underfloor heating.

Is the pump suitable for outdoor installation?
No, the IP44 rating provides protection against splashing water but not full submersion or heavy rain, so it should be installed in a sheltered location.

Can the pump be used with glycol-based fluids?
According to the manufacturer's technical data sheet, the pump is suitable for use with water-based fluids within the specified temperature range.

How is the pump speed adjusted?
The pump speed is adjusted using a switch mounted on the terminal block, which allows the user to select one of three speed settings based on the system's hydraulic requirements.
