Pumping group PrimoTherm K 180-2 DN25 AP 3-WM-SM, pump AFRISO APH 25-7/180, mixing valve ARV Kvs 12, actuator ARM 343 ProClick 7781320

Compact pump group for efficient temperature control

The PrimoTherm K 180-2 DN25 pump group is a ready-made solution for use in heating and cooling installations. Its compact design and precise components ensure reliable operation and easy installation for both professionals and end users. It is ideal for use on a KSV manifold, ABT buffer tank, or as an independent element of the installation.

Construction and application

The PrimoTherm K 180-2 group is designed for transferring medium (water or a water-glycol mixture up to 50% concentration) and precise temperature control of the heating circuit supply. A key element is the ARV Kvs 12 mixing valve, which, combined with the ARM 343 ProClick actuator, enables smooth and accurate temperature control. The AFRISO APH 25-7/180 circulation pump ensures efficient circulation of the medium in the installation.

An advantage of this pump group is the ability to easily change the supply and return sides, which facilitates adaptation to different installation schemes. It is equipped with the necessary components – thermometers, check valve, and shut-off valves on the supply and return – and the whole is protected by thermal insulation.

Key features and benefits

• Compact design: Smaller size compared to standard PrimoTherm groups makes installation easier in tight spaces.
• ARV Kvs 12 mixing valve: Provides precise temperature control of the medium, which translates to user comfort and energy savings.
• ARM 343 ProClick actuator: Enables quick and trouble-free installation of the mixing valve thanks to the ProClick system – no tools required.
• AFRISO APH 25-7/180 pump: Energy-efficient circulation pump with high performance, ensuring quiet operation and long life.
• Versatility: The ability to swap supply and return sides increases installation flexibility.
• Completeness: The set includes all the necessary elements for the correct operation of the pump group: mounting pins, compression sleeves for temperature sensors, gaskets, and an adapter for mounting the actuator.
• Safety: The maximum working pressure is 10 bar, and the maximum medium temperature is 90°C, which guarantees safe operation.
• Connections: It has connections from the installation side 2 x GW G1" and from the heat source side 2 x G1½". The connection spacing is 125 mm.
