## Long description

The Afriso PrimoTherm K 180-2 DN25 WP 3-WM-SM circulation pump group is a preassembled hydraulic unit designed for heating and domestic hot-water recirculation systems. The module integrates a Wilo Para circulation pump, an ARV Kvs12 mixing valve and an ARM 343 ProClick actuator to provide temperature control, flow regulation and automated mixing. Designed for DN25 pipe connections, the assembly simplifies installation, reduces on-site plumbing work and supports system balancing for reliable operation.
Advantages
This pump group arrives factory-assembled and pressure-tested to minimise installation time and potential leaks. Built-in hydraulic components allow precise temperature blending and stable flow through the recirculation loop, while the integrated actuator enables automated control without separate wiring of individual valves. Compatibility with DN25 pipework and the compact configuration save space in plant rooms and service cupboards.
Suitable for
 Domestic hot-water circulation and temperature stabilisation
 Heating systems requiring mixer control and return temperature regulation
 Retrofitting or replacing existing DN25 circulation groups
 Commercial small-scale systems in apartments, offices or public buildings
Key specifications
 Preassembled hydraulic unit with circulation pump, mixing valve and actuator
 Connection size: DN25
 Integrated circulation pump suitable for hydronic recirculation
 Mixing valve with Kvs value designed for controlled flow blending
 Electromechanical actuator for automated valve control
 Compact modular design for space-saving installation
 Intended for use in heating and domestic hot-water systems
How to use
Install the unit into the system using DN25-compatible pipework following local plumbing and heating codes. Connect the electrical supply to the actuator and the pump according to the wiring diagram provided by the manufacturer, observing safety and isolation procedures before work. Set the desired temperature or control parameters on the system controller so the actuator positions the mixing valve to achieve required return or supply temperatures. Commission the system by purging air from the loop, checking for leaks and verifying stable flow and temperature control across operating points.
Usage recommendations
 For reliable long-term performance, operate the unit within the temperature and pressure limits specified by the system designer, perform routine checks on pump operation and valve actuation, and schedule periodic maintenance including filter/strainer cleaning and actuator function tests. Use corrosion-inhibited water where specified and follow local regulations for installation and servicing.
