| Parameter | Details |
|---|---|
| General Information | |
| Seal Type | Queeny-M7N |
| Application | Ideal for use in various industrial pumps, compressors, and agitators across industries such as chemical, pharmaceutical, and food processing where reliable sealing is crucial. |
| Physical Properties | |
| Density | 2.1 g/cm³ |
| Hardness | 75 Shore D (approximate) |
| Mechanical Performance | |
| Pressure Rating | Maximum working pressure: 12 bar (174 psi) |
| Speed Limit | Up to 30 m/s |
| Temperature Range | -30°C to 180°C (-22°F to 356°F) |
| Geometric Dimensions | |
| Inner Diameter (ID) | Available in sizes from 15 mm to 250 mm |
| Outer Diameter (OD) | Corresponding to the inner diameter, with a typical radial width ranging from 6 mm to 12 mm depending on the ID size |
| Thickness | 4 mm to 10 mm |
| Sealing Face | |
| Surface Finish | Ra value of 0.25 µm (average) |
| Flatness | Within 0.0003 mm tolerance |
| Materials of Construction | |
| Seal Face | Rotating seal face: High-quality carbon-based material for excellent wear resistance. Stationary seal face: Tungsten carbide for superior hardness and durability. |
| Secondary Sealing Element | An elastomer with high chemical resistance and flexibility, suitable for a wide range of operating conditions. |
| Metal Parts | Constructed from stainless steel grade AISI 316L for corrosion resistance and strength. |
| Chemical Compatibility | |
| Compatible Fluids | Water (both fresh and distilled), mild alkaline solutions (up to 30% concentration), many organic solvents like ethanol, acetone (in appropriate concentrations), and some food-grade liquids such as milk and fruit juices. |
| Incompatible Fluids | Strong oxidizing agents like concentrated nitric acid, and highly reactive chemicals that can attack the elastomer or metal components. |
| Installation and Maintenance | |
| Installation Torque | For the mounting bolts (if applicable), the recommended torque is 12 - 25 Nm to ensure proper seating of the seal. |
| Lubrication | A thin layer of compatible lubricant (such as a food-grade grease for food industry applications) should be applied to the sealing surfaces and the elastomeric parts during installation to reduce friction and ensure smooth operation. |
| Maintenance Interval | Under normal operating conditions, it is advisable to inspect the seal every 8 - 10 months. However, in harsher environments or with more demanding fluids, the interval may need to be reduced to every 4 - 6 months. |
| Testing and Quality Assurance | |
| Pressure Test | The seal is subjected to a pressure test at 1.6 times the rated pressure for 45 minutes to ensure its integrity and ability to withstand high pressures. |
| Leakage Test | The maximum allowable leakage rate is set at 0.08 ml/h under standard test conditions. |
| Dimensional Inspection | All geometric dimensions are verified with a tolerance of ±0.03 mm to ensure proper fit and function. |
| Performance Characteristics | |
| Friction Coefficient | Between 0.15 and 0.22 depending on the operating conditions and the type of fluid. |
| Wear Rate | Under typical operating conditions, the wear rate of the seal face is less than 0.0008 mm/year. |
| Certifications | |
| ISO 9001:2015 certified manufacturing process for quality management. | |
| Meets FDA standards for use in food and pharmaceutical applications, ensuring compliance with hygiene and safety requirements. | |
| CE marked, indicating compliance with relevant European health, safety, and environmental protection regulations. |
