Product Description

Parameter Category	Specific Parameter	Detailed Description
Basic Information
Seal Type	QT 59U Mechanical Seal	A high - performance mechanical seal meticulously designed for industrial pumps, offering robust sealing solutions across diverse applications.
Brand	[Brand Name]
Model	QT 59U	Engineered to deliver reliable and long - lasting performance under various operating conditions.
Materials
- Rotating Ring	Tungsten Carbide	Tungsten carbide provides exceptional hardness and wear resistance, enabling the rotating ring to endure high - speed and high - pressure operations, ensuring a prolonged service life.
- Stationary Ring	Silicon Carbide (SiC)	SiC offers excellent corrosion resistance and a smooth surface finish, which is crucial for maintaining an effective seal.
- O - Ring	Fluoroelastomer (FKM)	The FKM O - ring ensures a tight and reliable seal, demonstrating resistance to a wide range of chemicals and temperature variations.
Size Specifications
Shaft Diameter Range	25 - 60 mm	Compatible with pump shafts within this diameter range, making it suitable for a broad spectrum of pump sizes.
Seal Chamber Inner Diameter	35 - 70 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 is carefully calibrated to strike a balance between efficient sealing and minimizing frictional forces.
Performance Parameters
Working Pressure	Maximum 2.0 MPa	Under normal operating circumstances, the seal can withstand a maximum pressure of 2.0 MPa, effectively preventing leakage of the pumped medium.
Working Temperature	-25ºC - 160ºC	Capable of operating efficiently within this extensive temperature range, adapting well to both low - temperature and high - temperature industrial environments.
Linear Velocity	Maximum 12 m/s	The seal is engineered to handle a maximum linear velocity of 12 m/s, ensuring stable and reliable performance even at high rotational speeds.
Applicable Media
- Water - based Fluids	Suitable for clean water, cooling water, and various water - based chemical solutions with a pH range of 2 - 13.
- Oil - based Fluids	Compatible with lubricating oils, gear oils, and most hydraulic oils.
- Chemical Fluids	Resistant to many common acids, alkalis, and organic solvents, but specific compatibility should be verified based on the actual medium.
Installation and Maintenance
Installation Method	Axial Installation	Installed axially onto the pump shaft following a precise installation procedure to ensure correct alignment and a secure seal.
Installation Torque	18 - 22 N·m	During installation, applying a torque within this range is essential to firmly secure the seal without causing damage due to over - tightening.
Maintenance Cycle	Every 4000 operating hours	Regular maintenance every 4000 operating hours is recommended, including inspection for signs of wear, leakage, and proper component alignment.
Storage Conditions	Store in a dry, dust - free environment at a temperature between 5ºC - 25ºC. Avoid exposure to direct sunlight and aggressive gases.	Proper storage conditions preserve the integrity of the seal components and prevent premature degradation.
Quality and Certification
Service Life	Approximately 2 - 3.5 years under normal operating conditions	With proper operation and regular maintenance, the QT 59U seal can provide reliable service for 2 - 3.5 years.
Leakage Rate	≤0.05 mL/h	Engineered to have an extremely low leakage rate, ensuring minimal loss of the pumped medium and maintaining system efficiency.
Certification Standards	ISO 9001, ISO 14001, and API 682 (if applicable)	Meets international quality management system standards (ISO 9001), environmental management system standards (ISO 14001), and may comply with API 682 requirements 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 performance even in vibration - prone industrial environments.
Self - lubricating Property	The seal faces are treated with a self - lubricating coating, reducing friction and wear during operation.	This self - lubricating feature enhances the seal's durability and reduces the need for additional lubrication.
