Group D-SA 250 DN 32 (1 1/4 inch) with insulation, without pump 619051

Compact pump group for various applications

The D-SA 250 DN 32 (1 1/4 inch) pump group is a ready-made solution for heating circuits, central heating installations, and domestic hot and cold water systems. It is characterized by its versatility and solid construction, making it suitable for both professional installers and end customers. This model is designed for mounting with a center distance of 250 mm.

Construction and components

The D-SA 250 DN 32 group is equipped with three brass ball valves – two with thermometers indicating the supply and return water temperature (with a built-in check valve), and a strainer that protects the installation from contaminants. Additionally, the set includes steel connectors and a set of gaskets (available in VITON or EPDM versions). The whole is protected with thermal insulation, minimizing heat loss.

Expandability and compatibility

This pump group has been designed with flexibility in mind. The ability to equip it with a pump from renowned manufacturers – Wilo or Grundfos – allows it to be adapted to the specific needs of the heating system. It is worth remembering that two DN 50 connectors are required to connect the group to C 2 125 or C 2 150 manifolds. Connectors with a check valve are also available to increase the functionality of the installation.

Operating parameters and safety

The D-SA 250 DN 32 pump group ensures safe and reliable operation in systems with a maximum working pressure of up to 6 bar and a temperature of up to 110°C. Solid construction with high-quality materials guarantees long-term operation.
