DBMA-1 type mechanical seal

The auxiliary seal adopts a typical welded metal bellows mechanical seal with an "O" ring, and the dynamic and static ring materials can be matched and combined according to different needs, suitable for various chemical fluids in industries such as petrochemicals, petroleum refining, petroleum extraction, metallurgy, food, medicine, and power.  
Design features:
Standardized design: compliant with DIN24960 and GB6556 standards
Metal bellows: welded structure, high compression ratio, moderate pressure resistance, eliminating the adverse effects of dynamic auxiliary sealing
Stress decomposition design: The inner circle of the corrugated tube adopts a 35 ° angle. Decompose the welding stress of the inner hole to prevent early damage
Non push type design: excellent followability and good dynamic compensation performance
Tightening screw positioning: simple and reliable, easy to adjust

Performance parameters of DBMA-1 mechanical seal:
Temperature: -40 ℃ -220 ℃
Pressure: 0-2.0Mpa, not recommended for working under high negative pressure or high vacuum conditions
Speed: 25m/s
Size range: 20-100mm, extra large sizes can be customized
