## Long description

Prefabricated circulation pump group Afriso MK DN25 with 3-way mixing valve and Grundfos UPM3 HYBRID 25-70 pump is a compact, factory-assembled module for hydronic heating systems. The unit combines a three-way mixing valve and a high-efficiency Grundfos UPM3 HYBRID pump to deliver controlled circulation and precise temperature blending. It is intended for integration with distribution manifolds, radiator circuits and underfloor heating installations that require DN25 connections and a compact pump group solution.
Advantages
The prefabricated design reduces installation time by delivering a ready-to-mount module with integrated hydraulic connections and mounting points. Integration of the 3-way mixing valve enables stable temperature regulation and reduces thermal shock to system components by blending supply and return flows. The Grundfos UPM3 HYBRID pump offers energy-efficient operation with variable-speed control for optimized flow and lower electrical consumption. The compact DN25 construction saves space and simplifies connection to existing piping layouts.
Suitable for
 Hydronic distribution manifolds in residential and light commercial heating systems
 Radiator circuits requiring blended supply temperatures
 Underfloor heating loops where precise temperature control is needed
 Retrofit installations that require a compact DN25 pump group
Key specifications
 Connection size: DN25 suitable for 1" piping systems
 Mixing valve type: three-way valve for blending supply and return flows
 Pump model: high-efficiency variable-speed circulation pump (Grundfos UPM3 HYBRID 25-70)
 Application: designed for heating circuits including radiators and underfloor heating
 Mounting: prefabricated, compact pump group for inline installation
How to use
Install the pump group in the supply circuit according to the hydraulic layout of the heating system, ensuring correct flow direction and secure DN25 connections. Connect the three-way mixing valve to the supply and return lines to allow blending of hot and return water for target temperature control. Electrically connect the pump following the pump manufacturer's wiring diagram and local electrical regulations. Commission the system by setting the required mixing valve position and adjusting the pump speed to achieve the desired flow and temperature balance. Verify tightness and proper operation before placing the system into regular service.
Usage recommendations
Use system-compatible antifreeze and water treatment where required and follow manufacturer guidance for pump maintenance intervals. For reliable operation, check electrical connections, valve operation and pump performance periodically, and purge air from the circuit after initial filling or maintenance.
