Pump group with a 3-way mixer, servomotor and WITA-Hocheffician pump

Pump group with 3-way mixer, servomotor and Wita high-efficiency pump

The WITA DN 25 pump group is the ideal solution for mixed heating circuits and is suitable for both residential and commercial heating systems. Thanks to its sophisticated design, it offers efficiency, durability, and installation flexibility. Whether with flow on the right or left, the installation can be easily adapted to meet the requirements of your heating system.

Powerful components for professional heating systems

The WITA pump group DN 25 impresses with its high-quality components, which ensure reliable and long-lasting operation. The central component is the 3-way T-mixer with bypass, which, in combination with the SM servomotor, W05 allows precise control of the heating circuit. The system is complemented by a Wita high-efficiency pump, which operates in a resource-saving manner while still providing sufficient power for larger systems.

The scope of delivery also includes two centrally positioned ball valves with integrated thermometers, allowing convenient temperature monitoring from 0 to 120 °C. A steel spacer with a cataphoretic coating and EPP insulation complete the set and ensure high-quality workmanship and optimal thermal insulation.

Technical data in detail

The pump assembly impresses with its compact dimensions and robust materials. With a diameter of DN 25 and a pump length of 180 mm, it can be easily installed in both boiler rooms and more confined spaces. The components are made of high-quality steel and brass, while PTFE and EPDM seals ensure perfect sealing. Thanks to its temperature resistance up to 110 °C and an operating pressure of up to 6 bar, the pump assembly is designed for demanding applications.

The Kvs value of 5.4 m³/h guarantees a high flow rate, while the center-mounted ball valves with thermometers facilitate operation and maintenance. The EPP insulation material not only contributes to energy efficiency but also protects the system from heat loss.

Application areas of the WITA pump group

The DN 25 pump assembly is ideal for mixed heating circuits and can be used in a variety of systems. It supports precise control of the heating water temperature, thus ensuring even heat distribution. The combination of a 3-way mixer, actuator, and high-efficiency pump is particularly effective in underfloor heating systems or systems with multiple radiators.

Thanks to its modular design, the pump group can be flexibly adapted to different requirements. Whether for single-family homes, multi-family homes, or commercial applications – this pump group offers the necessary performance and reliability to ensure optimal operation.

Energy savings thanks to modern Wita high-efficiency pump

The included Wita high-efficiency pump was specifically designed to save energy and reduce operating costs. Its contemporary design enables quiet operation and efficient operation, meeting the demands of modern heating systems.

By combining it with the servo motor SM W05 and the precise 3-way mixer ensure optimal control of the heating circuit. This not only increases comfort but also reduces operating costs.

Easy installation and flexible use

The WITA DN 25 pump group scores points for its simple installation. Its design and the option of positioning the flow line on either the right or left make installation particularly user-friendly.This makes the pump group suitable for both new installations and retrofitting existing systems.

In addition, the included EPP insulation ensures efficient heat distribution and minimizes energy losses. This saves costs in the long term and makes the heating system particularly environmentally friendly.

Conclusion: A well-thought-out solution for modern heating circuits

The pump assembly with 3-way mixer, actuator, and Wita high-efficiency pump is an excellent choice for anyone seeking a powerful and energy-saving solution for their heating system. High-quality materials, a sophisticated design, and flexible installation options make this product a worthwhile investment that increases efficiency and comfort in the long term.
