Circulation Pump WITA go.future 2, 60-32-180

Product detailed description

The WITA go.future 2 60-32-180 is designed for use in residential and commercial heating and water circulation systems. It is commonly installed in central heating systems, domestic hot water circuits, and underfloor heating applications. The pump’s proportional pressure control ensures that the flow adapts to the system’s current demand, reducing unnecessary energy use. This makes it suitable for both new installations and retrofit projects where energy efficiency is a priority. The pump is built to operate in environments with ambient temperatures between 0°C and 40°C and can handle media temperatures up to 110°C, making it adaptable to a wide range of system conditions.

With a maximum head of 6.0 m and a maximum flow rate of 3,600 l/h, the pump is ideal for systems requiring moderate hydraulic performance. The energy consumption ranges between 3 W and 42 W, depending on the operating conditions. The pump’s compact design and availability in various mounting lengths (110 mm, 130 mm, 180 mm) allow for flexible installation in tight spaces. The IP 42 rating ensures protection against splashing water, making it suitable for installation in utility rooms and other non-fully enclosed areas.

Technical parameters

Code	16034

The pump’s energy efficiency index (EEI) is ≤ 0.204, which is significantly lower than standard circulation pumps. This value is important for designers and engineers when evaluating the overall energy performance of a system. The pump’s proportional pressure control allows for four different pressure and power characteristics, enabling it to adapt to varying system demands. The maximum pressure rating of 1.0 MPa and the range of connection sizes (DN 15 to DN 32) ensure compatibility with a wide range of pipe diameters and system configurations.

Installation and connection

The pump should be installed in a horizontal position with the flow direction indicated on the housing. The DN 15 to DN 32 connections are available in either grey cast iron with cathodic protection or brass, depending on the model. When connecting the pump, ensure that the pipe diameter matches the DN size of the pump’s inlet and outlet. A minimum straight pipe length of 5 times the nominal diameter is recommended upstream and downstream of the pump to avoid turbulence. Common installation errors include incorrect orientation, insufficient pipe support, and failure to align the pump with the system’s flow requirements. Always verify the system’s pressure and flow requirements before final tightening of the connections.

Compatibility and accessories

The pump is compatible with standard heating and water systems that operate within the specified temperature and pressure ranges. For systems requiring external control, the pump can be connected to a PWM module for variable speed control. Additional accessories such as mounting brackets, sealing rings, and pressure sensors may be required depending on the system configuration. The pump does not require external motor protection, as it is built with integrated protection features. When selecting accessories, ensure that they are compatible with the pump’s IP rating and operating conditions.

Technical background for designers

The WITA go.future 2 60-32-180 operates on a proportional pressure control principle, where the pump adjusts its output to match the system’s current demand. This reduces energy consumption while maintaining stable flow and pressure. The pump’s body is constructed from either grey cast iron with cathodic protection or brass, depending on the model. These materials offer good corrosion resistance and mechanical strength, ensuring long-term reliability. The pump integrates into the system via standard flanged or threaded connections and is controlled via an internal microprocessor that adjusts the motor speed based on the selected pressure characteristic. The pump’s service life and efficiency are influenced by the quality of the installation, the cleanliness of the system fluid, and the stability of the electrical supply.

Service and operation

The pump requires minimal maintenance due to its sealed bearing design and integrated motor protection. Routine checks should include verifying the pump’s operation under load, inspecting the connections for leaks, and ensuring that the system is free from air pockets. The pump’s built-in night mode reduces energy consumption during periods of low demand. If the pump experiences blockage, the anti-blocking function will attempt to clear it automatically. There are no specified service intervals in the brief; however, it is recommended to inspect the pump during routine system maintenance. The pump’s energy consumption can be monitored via the built-in display, which is available on selected models.

Frequently asked questions

Can the pump be used in systems with media temperatures above 110°C?
No, the maximum media temperature is +110°C as specified in the technical data. Exceeding this may affect the pump’s performance and materials.

Is the pump compatible with PWM control modules?
Yes, the pump is available with a PWM input and can be connected to external control modules for variable speed operation.

Can the pump be used in vertical installations?
No, the pump is designed for horizontal installation only. Vertical mounting may affect the pump’s hydraulic performance and sealing integrity.

Is external motor protection required?
No, the pump does not require external motor protection as it is built with integrated protection features.
