The 7781070 model is a compact version of the PrimoTherm pump group, designed for both heating and cooling systems. It can be mounted on the KSV manifold, integrated with the ABT 160 buffer, or function as a standalone component within an installation. This pump group is engineered to circulate the medium throughout the system and precisely control the supply temperature of the heating circuit.

Equipped with an IBO IVO pump, this unit ensures efficient fluid movement. The ARV Kvs12 mixing valve is included to regulate flow rates, while the ARM 343 ProClick actuator provides precise control over the valve's operation. The pump group comes with essential components such as thermometers for monitoring temperature, a check valve to prevent backflow, and supply and return shut-off valves for easy maintenance and system isolation.

Additionally, the unit is wrapped in thermal insulation to minimize energy loss. The design allows for a straightforward swapping of supply and return pipes, enhancing installation flexibility. The 5902510009540 model number identifies this specific PrimoTherm K 180-2 DN25 IP 3-WM-SM pump group configuration, which offers a space-saving solution without compromising on functionality.
