Product Description

Parameter Category	Specific Parameter	Detailed Description
Basic Information
Seal Type	QT-MG12 Mechanical Seal	A high-performance mechanical seal meticulously designed for a wide range of industrial pumps, ensuring reliable operation and efficient sealing.
Brand	[Insert Brand Name]
Model	QT-MG12	This model is engineered to meet the demanding requirements of various pumping applications, providing consistent and stable sealing performance.
Materials
- Rotating Ring	Tungsten Carbide	Tungsten carbide offers exceptional hardness and wear resistance, enabling the rotating ring to withstand high-speed and high-pressure operations, thus extending the overall lifespan of the seal.
- Stationary Ring	Carbon Graphite	Carbon graphite provides excellent self-lubricating properties and good chemical resistance, contributing to smooth operation and effective sealing.
- O - Ring	Ethylene Propylene Diene Monomer (EPDM)	The EPDM O - ring ensures a tight seal and exhibits excellent resistance to water, steam, and a variety of chemicals, making it suitable for diverse media.
Size Specifications
Shaft Diameter Range	25 - 55 mm	This seal can be installed on shafts with diameters within this range, making it adaptable to numerous pump models with different shaft sizes.
Seal Chamber Inner Diameter	35 - 65 mm	Specifically designed to fit into seal chambers with inner diameters in this range, guaranteeing proper installation and optimal performance.
Seal Width	9 mm	The 9 - mm width of the seal is optimized to strike a balance between achieving a reliable seal and minimizing frictional losses during operation.
Performance Parameters
Working Pressure	Maximum 1.8 MPa	Under normal operating conditions, the QT-MG12 seal can endure a maximum pressure of 1.8 MPa, effectively preventing the leakage of the pumped medium.
Working Temperature	-30ºC - 180ºC	Capable of operating efficiently within this wide temperature range, it is suitable for applications involving both extremely cold and relatively high-temperature environments.
Linear Velocity	Maximum 12 m/s	The seal is engineered to handle a maximum linear velocity of 12 m/s, ensuring stable performance even in high-speed pumping operations.
Applicable Media
- Water and Aqueous Solutions	Suitable for clean water, industrial wastewater, and various aqueous solutions with a pH range of 2 - 13, showing good chemical stability.
- Oil-based Fluids	Compatible with mineral oils, synthetic lubricants, and most hydraulic oils, making it ideal for oil-related pumping applications.
- Chemical Liquids	Can be used with certain non - aggressive chemical liquids, such as weak acids and alkalis within the specified pH range.
Installation and Maintenance
Installation Method	Axial Installation	Installed axially onto the pump shaft following a precise installation procedure to ensure accurate alignment and a secure seal.
Installation Torque	18 - 23 N·m	During installation, a torque within this range should be applied to firmly secure the seal without causing damage to its components.
Maintenance Cycle	Every 4000 operating hours	Regular maintenance is recommended every 4000 operating hours. This includes inspecting the seal for signs of wear, leakage, and any potential damage to ensure continuous reliable performance.
Storage Conditions	Store in a dry, cool place with a temperature range of 5ºC - 25ºC. Keep away from direct sunlight, moisture, and corrosive substances.	Proper storage conditions are essential to maintain the integrity of the seal materials and prevent premature degradation.
Quality and Certification
Service Life	Approximately 2 - 4 years under normal operating conditions	With proper operation and regular maintenance, the QT-MG12 seal can provide reliable service for 2 - 4 years, ensuring long - term cost - effectiveness.
Leakage Rate	≤0.05 mL/h	Engineered to have an extremely low leakage rate, the seal effectively minimizes the loss of the pumped medium, enhancing operational safety and efficiency.
Certification Standards	ISO 9001, ISO 14001, and industry - specific certifications (if applicable)	The seal complies with international quality management (ISO 9001) and environmental management (ISO 14001) standards, and may also hold other relevant industry certifications depending on the application.
Other Characteristics
Vibration Resistance	Can withstand vibrations with a frequency range of 8 - 60 Hz and an amplitude of 0.6 mm.	Designed to maintain its sealing integrity even in environments with significant vibrations, ensuring stable pump operation.
Self-lubricating Property	The contact surfaces of the seal are treated with a special self-lubricating coating.	This self-lubricating feature reduces friction between the seal components, minimizing wear and extending the seal's service life.
