OEG 512245103 - Pump group for unmixed circuit

Pump group for unmixed heating circuits

The OEG 512245103 pump group for unmixed circuit is designed for heating installations where the water is circulated directly through the circuit without mixing control. This heating circuit pump set is suitable for OEG DN25 circulation pumps with an installation length of 130 or 180 mm.

Suitable for DN25 circulation pumps

The pump group can be used in heating systems, boiler circuits, buffer tank systems and hydraulic distribution setups. With suitable screw connections, the set can be adapted to different pump installation lengths.

Easy maintenance with ball valves

The integrated ball valves make pump maintenance much easier. The circulation pump can be isolated without draining the entire heating system, saving time during service work and reducing system downtime.

Flow and return temperature monitoring

Integrated thermometers allow direct checking of flow and return temperatures. This helps installers quickly assess the heating circuit during commissioning, adjustment or maintenance.

Insulated design to reduce heat loss

The insulation reduces heat loss to the surrounding environment and contributes to more efficient system operation. This is especially useful in plant rooms where multiple components are installed close together.

Flexible installation and service

The practical design and compatibility with different pump lengths make the OEG 512245103 a flexible solution for professional installers. Note: to mount the ball valve of the boiler circuit onto the pump, a screw connection from the circulation pump is used.
