SMT 125 group - DN 32 (1 1/4 inch) without pump with 3-way mixing valve MIX MT 607061

Pumping unit with mixing valve – an optimal solution for your installation

The SMT 125 - DN 32 pumping unit is a complete solution for constant-temperature heating circuits. Equipped with a three-way mixing valve MIX MT, it provides precise temperature control and user comfort. Its compact design simplifies installation and integration with existing systems, while its solid construction guarantees years of reliable operation. Ideal for both professional installers and demanding end-users.

Construction and application

The pumping unit is designed for efficient heat distribution in heating systems. The MIX MT 32 mixing valve allows you to regulate the temperature of the heating medium, ensuring optimal conditions in the rooms. This makes it possible to connect to various heat sources, such as gas, oil boilers or heat pumps. A center distance of 125 mm ensures compatibility with most standard installations. Ball valves with thermometers allow for continuous monitoring of system operating parameters.

Key features and benefits

• MIX MT 32 mixing valve: Precise temperature control, manual or automatic operation possible (with MP 06 actuator – available separately). The valve has a bypass, which increases system flexibility.
• Solid construction: The use of CW 617N forged brass in the mixing valve and high-quality steel in the spacer connector guarantees durability and corrosion resistance.
• EPP insulation: High-quality EPP insulation with a thickness of 60 g/l minimizes heat loss and ensures system energy efficiency. An open space around the pump facilitates servicing and replacement of the device.
• Universal connections: GZ 2” threads (boiler side) and GW 1 1/4” (installation side) ensure easy integration with various installation elements.
• Safety: The maximum working pressure is 8 bar and the maximum temperature is 110°C, ensuring safe system operation. Seals made of VITON or EPDM guarantee the tightness and reliability of connections.
• Flexible mounting: The unit can be wall-mounted using expansion bolts. The supply side can be changed depending on installation requirements.
• Thermometers in ball valves: Allow quick reading of the heating medium temperature on the supply and return, which facilitates diagnostics and optimization of system operation.
