Group D-SA 250 DN 40 (1 1/2) with insulation, without pump, pump connection length 250mm 629052

Pump group for heating and domestic hot water installations

The D-SA 250 DN 40 (1 1/2”) pump group is a ready-made solution for radiator circuits, domestic hot water (DHW) or central heating (CH). Designed for easy installation and efficient operation, it is an integral part of modern heating systems. A center distance of 250 mm ensures compatibility with most standard installations, and the pump installation length of 250 mm facilitates the replacement of existing devices.

Design and application

The pump group is equipped with a complete set of steel connectors, a slanted filter to protect against impurities, two thermometers for temperature control, and additional 1/2” female thread (GW) outlets on the supply and return – useful for connecting additional installation elements. The whole is insulated, which minimizes heat loss and improves the energy efficiency of the system. It should be noted that the group does not include shut-off valves – it is recommended to install ball valves from the installation side and DN 50 gate valves from the boiler side, which can be purchased separately.

Key features and benefits
