## Long description

The Circulation pump group Afriso PrimoTherm K 180-2 DN25 with AFRISO APH pump and ARV Kvs12 (S) mixing valve is a compact hydraulic assembly designed for circulation and temperature regulation in heating and domestic hot-water recirculation systems. Built for DN25 pipe connections, the unit integrates a variable-speed AFRISO APH circulation pump with a 3‑way mixing valve to maintain required delivery temperatures and ensure steady flow in residential and light-commercial installations.
Advantages
The integrated design combines pump and mixing valve in a single compact unit, saving installation space and simplifying hydraulic connections. The AFRISO APH pump offers energy-efficient operation and adjustable performance to match system demand, while the ARV Kvs12 (S) mixing valve provides reliable temperature control and stable mixing characteristics. The assembly is suitable for inline mounting on DN25 pipework and reduces the need for separate components, lowering potential leak points and installation time.
Suitable for
 Hot water recirculation loops in residential buildings
 Heating circuits requiring temperature regulation and circulation
 Small commercial installations with DN25 piping
 Retrofit projects where a compact pump/mixing solution is needed

How to use
Install the circulation pump group in the return or supply line following hydraulic diagrams and local plumbing codes, ensuring correct orientation for flow and valve porting. Connect DN25 piping using appropriate fittings and secure electrical supply to the AFRISO APH pump according to the pump wiring instructions. Set the mixing valve to the required temperature setpoint and adjust the pump speed to achieve desired flow and system balancing. Commission the system by purging air, verifying pump operation, and checking mixed outlet temperature under typical load conditions.
Usage recommendations
Use the unit in systems with compatible DN25 piping and maintain access for periodic inspection. Follow manufacturer guidance for electrical connection, winterization, and routine maintenance of the pump and valve.
