Product Description Parameter CategorySpecific ParameterDetailed DescriptionBasic Information Seal TypeQueeny-Carbon graphite Mechanical SealA specialized mechanical seal leveraging carbon graphite material, providing excellent sealing performance for various industrial pumps and equipment.ModelQueeny-Carbon graphiteDesigned to meet the requirements of applications where chemical resistance, self-lubrication, and thermal stability are crucial.Materials - Rotating RingCarbon GraphiteOffers superior self-lubricating properties, reducing friction and wear. It also has good chemical resistance, making it suitable for a wide range of media.- Stationary RingSilicon Carbide (SiC)SiC provides high hardness and wear resistance, ensuring long - term durability when paired with the carbon graphite rotating ring.- O-RingFluoroelastomer (FKM)FKM O - ring provides a tight seal and is resistant to various chemicals and temperatures, ensuring reliable performance.Size Specifications Shaft Diameter Range18 - 45 mmCompatible with pump shafts within this diameter range, suitable for different pump models and sizes.Seal Chamber Inner Diameter28 - 55 mmDesigned to fit into seal chambers with inner diameters in this range for proper installation and operation.Seal Width8 mmThe 8 - mm width is optimized to balance effective sealing and reduced friction, enhancing the overall efficiency of the sealing system.Performance Parameters Working PressureMaximum 1.5 MPaUnder normal operating conditions, the seal can withstand a maximum pressure of 1.5 MPa to prevent leakage of the pumped medium.Working Temperature-20oC - 160oCCapable of operating effectively within this temperature range, adapting to both cold and relatively high - temperature working environments.Linear VelocityMaximum 10 m/sEnsures stable sealing performance even when the pump operates at a high rotational speed with a maximum linear velocity of 10 m/s.Applicable Media - Water-based FluidsSuitable for clean water, sewage, and water-based chemical solutions with a pH range of 3 - 11. - Oil-based FluidsCan be used with lubricating oils, hydraulic oils, and some light hydrocarbon oils. - Chemical SolutionsResistant to many organic solvents, weak acids, and alkalis, making it suitable for chemical processing applications. Installation and Maintenance Installation MethodAxial InstallationInstalled axially onto the pump shaft following a standard installation procedure to ensure proper alignment and a tight seal.Installation Torque13 - 17 N·mApply a torque within this range during installation to secure the seal without causing damage to its components.Maintenance CycleEvery 3500 operating hoursRegular maintenance is recommended every 3500 operating hours, including inspection for wear, leakage, and proper alignment.Storage ConditionsStore in a dry, dark place at a temperature between 0oC - 30oC, away from corrosive gases.Proper storage helps maintain the integrity of the seal components and extends their shelf life.Quality and Certification Service LifeApproximately 1.8 - 2.8 years under normal operating conditionsWith proper operation and maintenance, the seal can provide reliable service for 1.8 - 2.8 years.Leakage Rate≤0.09 mL/hEngineered to have a low leakage rate, ensuring the containment of the pumped medium and minimizing environmental impact.Certification StandardsISO 9001, ISO 14001Meets the requirements of ISO 9001 quality management system standards and ISO 14001 environmental management system standards.Other Characteristics Vibration ResistanceCan withstand vibrations with a frequency range of 5 - 45 Hz and an amplitude of 0.45 mm.Maintains sealing performance in environments with moderate vibrations, ensuring stable operation of the equipment.Self-lubricating PropertyThe carbon graphite material inherently has self-lubricating characteristics, reducing the need for additional lubrication and extending the seal's lifespan. Carbon graphite is used as a soft material in a wide range of applications, from wet running to dry running. It provides:- Excellent natural lubricity- Good thermal conductivity- Outstanding thermal shock resistance- Good corrosion resistanceMechanical carbon has been developed in different grades to meet various service conditions:- Resin bonded carbon: An economic, pressed to size material for large volume requirements- Resin impregnated carbon: Furan resin, Phenolic resin, or Epoxy resin are used as filler to decrease the porosity of carbon- Metal impregnated carbn: Antimony, Copper, or Babbitt alloys are used as filler for applications requiring higher working temperatures or higher strength.
