Circulating group D-SA 250 DN 25 (1 inch) with insulation, without pump 609051

Compact pump group for various applications

The D-SA 250 DN 25 (1 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 a compact design and versatility, making it ideal for both professional installers and end customers. This model is supplied without a pump, allowing you to choose the appropriate model depending on the specifics of the installation.

Construction and application

The D-SA 250 group consists of high-quality components, including three brass ball valves (two with thermometers indicating supply and return temperature), a strainer, steel connectors, and thermal insulation. A center distance of 250 mm ensures compatibility with popular manifolds available on the market. This makes installation and integration with the existing heating system smooth and trouble-free.

• Ball valves with thermometers allow for precise control of the installation parameters.
• The strainer prevents the retention of impurities, protecting system components from damage and ensuring its long-term performance.
• Thermal insulation minimizes heat loss, increasing the energy efficiency of the system.
• The ability to adapt the pump (Wilo or Grundfos – available separately) allows for optimal operation of the group to specific needs.

Operating parameters and safety

The D-SA 250 pump group is designed to operate in demanding conditions. The maximum working pressure is 6 bar, and the maximum medium temperature is 110°C. Seals made of VITON or EPDM guarantee tightness and resistance to the action of chemical agents present in heating installations. Solid construction and high-quality materials ensure reliability and long service life of the device.
