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

Pump group with 3-way mixer, actuator 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 flexible installation. Whether with the flow on the right or left, the installation can be easily adapted to meet the requirements of your heating system.

High-performance components for professional heating systems

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

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

Technical specifications in detail

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

The Kvs value of 5.4 m³/h guarantees a high flow rate, while the centrally located ball valves with thermometers simplify 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 group is ideally suited for mixed heating circuits and can be used in various systems. It supports precise control of the heating water temperature, thus ensuring even heat distribution. The combination of a 3-way mixing valve, actuator, and high-efficiency pump particularly shines 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, apartment buildings, 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 specially developed to save energy and reduce operating costs. Its modern design enables quiet operation and efficient performance that meets the requirements of modern heating systems.

By combining it with the SM actuator W05 The precise 3-way mixing valve ensures optimal control of the heating circuit. This not only increases comfort but also contributes to saving operating costs.

Easy installation and flexible use

The WITA DN 25 pump group stands out due to its simple installation. Its design and the option of placing the flow pipe on either the right or left side make installation particularly user-friendly.This makes the pump group suitable for both new installations and the retrofitting of existing systems.

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

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

The pump unit with 3-way mixing valve, 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 well-engineered design, and flexible installation options make this product a worthwhile investment that will increase efficiency and comfort in the long run.
