Difference from DI7240N
- Bellows material: DI7240A-EA uses ACS EPDM (stated in the datasheet); DI7240N uses EPDM.
- PN rating: DI7240A-EA is PN10/16 from DN32 to DN150 and PN16 from DN200 to DN600; DI7240N is PN10 from DN200 to DN600.
- Dimensions: length L, flange outer diameter ØD and the Lc / Le / Li / A values are the same as DI7240N; flange thickness b differs at every DN, ØK differs from DN250, the bolt hole count and diameter differ at some DNs, and so do the weights (for example DN600: 79.8 kg vs 68.00 kg).
- Working conditions: the DI7240A-EA datasheet states a maximum working pressure of 10 bar and a temperature of -30°C / +120°C with its own pressure-temperature chart; DI7240N has only a temperature-pressure chart.
Applications
Reduces mechanical and thermal stress on pipes and related equipment (pumps, compressors, motors); absorbs vibration and noise; compensates axial, lateral and angular movement; corrects piping misalignment. Fluids: hot and cold water (per the datasheet).
Standards / Certifications
Flanges to EN 1092-1 (PN10/16 from DN32 to DN150, PN16 from DN200 to DN600); pressure tests to EN 12266-1, DIN 3230 and ISO 5208. The datasheet states the material “ACS EPDM” but does not explain the ACS marking and states no approval certificate or drinking-water use for this code.
