Group SA 125 - DN 32 (1 1/4 inch) without pump 607051

Heating and Domestic Hot Water Circulator Group

The SA 125 - DN 32 circulator group is a compact solution designed for radiator circuits, domestic hot water (DHW) installations, and central heating (CH). Designed for efficient heat distribution, it works well in both home installations and public utility facilities. Its versatility will be appreciated by both professional installers and end-users looking for a reliable heating system.

Construction and application

The group consists of three brass ball valves – two with built-in thermometers indicating the supply and return water temperature, and a check valve in the return valve. It is also equipped with a steel spacer connector and EPP insulation, which minimizes heat loss. A center distance of 125 mm ensures compatibility with most standard installations. The possibility of mounting a circulation pump (option) from Grundfos or WILO allows the group to be adapted to individual needs and heating system parameters.

Advantages and product features

• Versatility: Suitable for radiator circuits, DHW and CH, making it a versatile element of the heating installation.
• High quality workmanship: Brass ball valves guarantee durability and corrosion resistance.
• Precise temperature measurement: Built-in thermometers allow for continuous monitoring of installation parameters.
• Effective insulation: EPP insulation with a thickness of 60 g/l reduces heat loss, affecting energy savings.
• Easy installation: Wall mounting is possible thanks to dedicated recesses in the insulation, making installation easier even in difficult conditions.
• Flexible connections: The supply side is located on the right side by default, but it can be easily changed, adapting the group to a specific installation configuration.
• Safety: The maximum working pressure is 8 bar, and the maximum temperature is 110°C, ensuring safe operation of the heating system.
• Compatibility: GW 1 1/4” (installation side) and GZ 2” (boiler side) connections ensure easy connection to the existing heating infrastructure.
• Expandability: The possibility of equipping with a Grundfos or WILO circulation pump increases the functionality of the pump group.

The SA 125 - DN 32 group is characterized by a maximum working pressure of 8 bar and a maximum operating temperature of 110°C. The insulation is made of EPP with a density of 60 g/l, which ensures energy efficiency. The center distance is 125 mm, and the seals are made of VITON or EPDM to ensure the tightness and durability of the connections. The connection from the installation side is GW 1 1/4”, and from the boiler side GZ 2”. The pump installation length is 180 mm, and the pump connection is GZ 2”.

The SA 125 - DN 32 group is a solid and reliable solution for any heating system, which will provide thermal comfort and efficient energy use for years to come.
