Circulation Pump WITA go.future 2, 40-32-180

Product detailed description

This circulation pump is designed for use in residential and small commercial buildings where efficient fluid transport is required within heating and water systems. It is commonly installed in central heating circuits, hot water loops, and underfloor heating applications. The pump adjusts its output to match system demand, ensuring consistent performance while reducing energy consumption compared to traditional models.

With its proportional pressure control feature, the pump adapts to varying load conditions, maintaining system stability without unnecessary power draw. The compact design allows for flexible installation in tight spaces, and the range of connection sizes supports integration into various pipe configurations. Its low energy index and built-in protection mechanisms make it suitable for modern low-energy and smart home systems.

Technical parameters

Installation and connection

Installation begins with selecting the appropriate DN size (15, 20, 25, or 32) based on the pipe system. Ensure the pump is mounted horizontally and aligned with the flow direction. Secure the pump using the provided mounting brackets and connect the electrical supply via a standard single-phase 230V, 50 Hz connection. Verify the system pressure does not exceed 1.0 MPa and that ambient temperatures remain between 0°C and 40°C. Common errors include incorrect orientation, failure to align the flow arrows, and neglecting to check motor protection requirements, which are not required for this model.

Compatibility and accessories

This pump is compatible with standard heating and water distribution systems requiring proportional pressure control. For advanced control options, the PWM module can be added separately. Additional accessories such as mounting brackets or extension cables may be needed depending on the installation location and system layout. The pump is available in versions with and without a display for monitoring energy usage.

Technical background for designers

The WITA go.future 2 operates using a variable-speed motor that adjusts output based on system demand. This ensures efficient energy use while maintaining stable pressure levels. The IP42 rating provides protection against dust and splashing water, making it suitable for indoor use. Long-term efficiency depends on regular system checks and ensuring the media temperature remains within the specified range of +5°C to +110°C.

Service and operation

Regular maintenance includes checking for blockages and verifying the pump operates without unusual noise or vibration. No scheduled service intervals are required, but the anti-blocking function helps prevent issues during low-flow periods. Monitor the system for signs of wear and ensure the pump remains free from debris. The night mode and energy display assist in managing long-term energy costs.

Frequently asked questions

Can the pump be used in a solar heating system?
Yes, provided the system operates within the specified temperature and pressure limits. The proportional pressure control is well-suited for variable load conditions typical in solar applications.

Is an external motor protection device required?
No, the pump is designed with integrated motor protection, eliminating the need for additional components.

How does the night mode affect performance?
The night mode reduces pump speed during off-peak hours to further lower energy consumption without compromising system functionality.

Can the pump be controlled using a third-party controller?
Yes, the PWM input allows for external control, enabling integration with smart thermostats or building management systems.
