## Summary description

Circulation pump group Afriso PrimoTherm K 180-2 DN25 integrates an AFRISO APH circulation pump, ARV mixing valve with Kvs 12 flow coefficient and ARM 343 ProClick actuator (MPN 7781320). Designed for hydronic heating systems, the DN25 assembly provides controlled mixing and pump circulation for radiators, underfloor heating and boiler loop regulation. Typical use cases include system balancing, temperature control and efficient heat distribution in residential and light-commercial installations.

## Long description

The Circulation pump group Afriso PrimoTherm K 180-2 DN25 with AFRISO APH pump, ARV mixing valve Kvs 12 and ARM 343 ProClick actuator is a compact pre-assembled unit for hydronic heating systems. It combines a circulation pump, a thermostatic mixing valve with defined Kvs 12 flow coefficient and an electric actuator into a DN25 assembly intended to provide controlled circulation and temperature mixing. The group is intended for integration into radiator circuits, underfloor heating manifolds and boiler loop regulation where reliable flow control and temperature regulation are required.
Advantages
The integrated design reduces installation time by delivering pump, valve and actuator already mounted and adjusted for compatibility. The ARV mixing valve with Kvs 12 provides predictable flow behaviour for accurate temperature mixing, while the ARM 343 ProClick actuator allows straightforward electrical connection and simple commissioning. The AFRISO APH pump is sized for typical residential and light-commercial circuits, offering stable circulation and quiet operation when installed according to system requirements.
Suitable for
 Balancing and circulation of radiator heating circuits
 Integration with underfloor heating manifolds requiring DN25 connection
 Boiler loop regulation and domestic hot water recirculation when mixing is needed
 Retrofit or new-build residential and light-commercial hydronic systems
Key specifications
 Connection size: DN25
 Included pump type: circulation pump designed for hydronic heating
 Mixing valve flow coefficient: Kvs 12
 Actuator type: ProClick electric actuator for motorised valve control
 Assembly: pre-mounted pump, valve and actuator in a single unit
How to use
Install the pump group in the return or supply line according to system design and flow direction markings. Connect hydraulic fittings using appropriate sealing and mountings for DN25 piping. Wire the ARM 343 ProClick actuator to the control circuit following the actuator wiring diagram and local electrical regulations. Commission the system by setting the mixing valve position or control input to achieve the required supply or return temperature, then verify pump operation and system flow under typical load conditions.
Usage recommendations
Use the unit with compatible system fluids and adhere to maximum temperature and pressure limits of the overall hydronic installation. Regularly inspect electrical connections and valve operation, and perform flushing and filtration before installation to reduce the risk of pump or valve blockage. For optimal performance, follow manufacturer instructions for mounting orientation and periodic maintenance intervals.
