Double bellows rubber compensator for decoupling structure-borne sound from heat pumps and heating systems. Absorbs vibrations and movements caused by pumps, compressors, fittings, etc. Reduces noise and compensates for tensions (axial and lateral differences) caused by assembly inaccuracies. Bellows made of EPDM, IG connections made of malleable cast iron, operating temperature -10°C to 110°C. Max. operating pressure 8 bar at 70 °C flow temperature, scope of delivery 2 pieces. Compression 22 mm (stroke 10 / -12), expansion 6 mm, lateral movement 22 mm, angular stroke 45°. Horizontal installation, as close to the heat pump as possible, is recommended!
