EVOPLUS B 40/220.32 M Electronic circulator for small heating and air conditioning systems - flanged DAB.EVOPLUS SMALL

Product detailed description

The EVOPLUS B 40/220.32 M is commonly used in small residential and commercial heating systems, including underfloor heating and split-level buildings. It supports systems with varying load demands by adapting its performance to hydraulic changes. Installers typically handle tasks such as mounting the pump in the correct orientation, verifying pipe alignment, and ensuring electrical compatibility with control systems.

This model is ideal for installations where energy efficiency and precise control are essential. It integrates well with thermostats and building management systems, allowing for automated operation based on real-time conditions. The pump is suited for environments with fluctuating temperatures and fluid properties similar to water, such as glycol mixtures with up to 30% concentration.

Technical parameters

The nominal flow rate (DN 32) defines the standard size of the flanged connection, while the pressure rating (PN 6/PN 10) determines the maximum allowable working pressure for the system. These parameters are crucial for selecting the correct pump size and ensuring compatibility with existing piping and fittings.

Installation and connection

Install the pump with the motor shaft in a horizontal position to ensure proper operation. The flanged connection requires DN 32 flanges with PN 6 or PN 10 ratings. Verify that the flange surfaces are clean and aligned before bolting. Use appropriate gaskets compatible with the operating temperature range (-10°C to +110°C) to prevent leaks.

Common installation errors include misalignment of the flanges, incorrect torque on bolts, and improper grounding. Always check the electrical supply (1x230 V/50/60 Hz) and confirm that the motor is protected against dust and moisture (IP44 rating). Avoid installing the pump near sources of vibration or heat exceeding the maximum allowable temperature.

Compatibility and accessories

The EVOPLUS B 40/220.32 M is compatible with control systems that support frequency modulation. It can be integrated with thermostats, room controllers, and building automation systems. For complete installation, additional components such as isolation valves, pressure gauges, and flow meters may be required. Ensure that all accessories meet the system’s pressure and temperature requirements.

Technical background for designers

The pump operates using a synchronous motor with permanent magnets controlled by a frequency converter. This allows for precise adjustment of the motor speed in response to hydraulic changes in the system. The motor is constructed with materials that resist corrosion and wear, ensuring long-term reliability in aggressive environments. The system design should account for the fluid properties, such as viscosity and chemical neutrality, to maintain optimal performance.

The integration of the pump into the system depends on the layout of the pipes, the location of control devices, and the overall hydraulic balance. Proper sizing of the pump ensures that it can handle the required flow and pressure without excessive energy consumption. The operating range (2 to 12 m³/h) and maximum head (11 m) are key factors in determining the suitability of the pump for a specific application.

Service and operation

Regular maintenance includes visual inspections for leaks, checking the tightness of flange bolts, and verifying the integrity of electrical connections. No scheduled service intervals are specified in the technical data, but any signs of abnormal noise, vibration, or reduced performance should prompt further investigation. Ensure that the pump is not operated beyond its maximum pressure limit (16 bar) to avoid mechanical stress and potential failure.

Frequently asked questions

Can the EVOPLUS B 40/220.32 M operate with glycol-based fluids?
Yes, provided the glycol concentration does not exceed 30%. The pump is designed for fluids with properties similar to water.

Is it possible to connect the pump to a variable speed controller?
Yes, the pump is compatible with frequency inverters for speed control. Ensure the controller matches the voltage and frequency specifications (1x230 V/50/60 Hz).

What is the maximum allowable operating pressure?
The maximum working pressure is 16 bar. Exceeding this may lead to mechanical failure or seal damage.

Can the pump be installed vertically?
No, the pump must be installed with the motor shaft in a horizontal position to ensure proper function and longevity.
