Key Features of Unbalanced /Balanced Multispring Seals For Petrochemical Sector

• Precision Lapped Sealing Faces: Lapping process results in high precision finish with optimal flatness.
• Balanced/Unbalanced Designs: Positive hydraulic balancing permits use in high pressure. Unbalanced design can be used for lower pressure applications, saves cost.
• Even Face Pressure: The multi-spring designs ensure even face pressure for minimal face wear and compensation for some shaft misalignment.
• Compact Design: Permits use in all types of rotating equipments such as centrifugal pumps, mixers, and agitators.
• Field Repairable: Reduces inventory requirements. Seals can be repaired easily on site or at any Daybreak`s seal repair centers, and/or converted to various seal face combinations.
• Size range: 3/8" to 8" [10mm to 200 mm]
• Temperature: -50c degree to + 500 c degree /-60 F degree to 930 F degree depending on the material used.
• Pressure: Type DB-MU-Up to 17 bar g/247 psig, Type DB-MB Up to 62 bar g/900 psig.
• Speed: Up to 6000 RPM according to seal size and working pressure.
• General chemical applications, oil refining and petrochemical, Pharmaceutical industries.
• Suitable for use with abrasive clear and corrosive fluids and for cryogenic and high temperature applications.
• By choosing suitable component material the seals can be adapted to operate with a wide range of liquid and operating conditions
