Product Description

Parameter Category	Specific Parameter	Detailed Description
Basic Information
Seal Type	QT UNE5 Mechanical Seal	A high - performance mechanical seal innovatively designed for a wide range of industrial pumps, providing superior sealing solutions across multiple applications.
Brand	[Brand Name]
Model	QT UNE5	Engineered to offer stable and long - lasting performance under diverse and challenging operating conditions.
Materials
- Rotating Ring	Tungsten Carbide (WC)	Tungsten carbide offers outstanding hardness and wear resistance, allowing the rotating ring to endure intense high - speed and high - pressure operations, ensuring an extended service life.
- Stationary Ring	Carbon Graphite	Carbon graphite provides excellent self - lubricating properties and low friction, which are vital for maintaining a reliable and efficient seal.
- O - Ring	Fluoroelastomer (FKM)	The FKM O - ring ensures a tight and dependable seal, demonstrating remarkable resistance to a broad spectrum of chemicals and significant temperature fluctuations.
Size Specifications
Shaft Diameter Range	18 - 45 mm	Compatible with pump shafts within this diameter range, making it suitable for various medium - sized pump applications.
Seal Chamber Inner Diameter	28 - 55 mm	Specifically designed to fit into seal chambers with inner diameters in this range, ensuring proper installation and peak performance.
Seal Width	8 mm	The 8 - mm width is carefully optimized to achieve an ideal balance between effective sealing and minimizing unnecessary frictional resistance.
Performance Parameters
Working Pressure	Maximum 1.8 MPa	Under normal operating conditions, the seal can endure a maximum pressure of 1.8 MPa, effectively preventing leakage of the pumped medium.
Working Temperature	-20ºC - 140ºC	Capable of operating efficiently within this wide temperature range, adapting well to different industrial temperature environments, from cold - storage applications to moderately high - temperature processes.
Linear Velocity	Maximum 10 m/s	The seal is engineered to handle a maximum linear velocity of 10 m/s, ensuring stable and consistent performance even at relatively high rotational speeds.
Applicable Media
- Water - based Fluids	Suitable for clean water, process water, and various water - based chemical solutions with a pH range of 3 - 12.
- Oil - based Fluids	Compatible with common lubricating oils, turbine oils, and most types of hydraulic oils.
- Chemical Fluids	Resistant to many typical acids, alkalis, and a number of organic solvents, but specific compatibility should be verified based on the actual medium's properties.
Installation and Maintenance
Installation Method	Axial Installation	Installed axially onto the pump shaft following a precise and standardized installation procedure to ensure correct alignment and a secure seal.
Installation Torque	15 - 18 N·m	During installation, applying a torque within this range is crucial to firmly secure the seal without causing damage due to over - tightening or insufficient tightness.
Maintenance Cycle	Every 3500 operating hours	Regular maintenance every 3500 operating hours is recommended, including thorough inspection for signs of wear, leakage, and proper alignment of all components.
Storage Conditions	Store in a dry, well - ventilated environment at a temperature between 8ºC - 22ºC. Keep away from direct sunlight, moisture, and corrosive gases.	Proper storage conditions help preserve the integrity of the seal components and prevent premature deterioration.
Quality and Certification
Service Life	Approximately 1.5 - 3 years under normal operating conditions	With proper operation and regular maintenance, the QT UNE5 seal can provide reliable service for 1.5 to 3 years.
Leakage Rate	≤0.06 mL/h	Engineered to have an extremely low leakage rate, ensuring minimal loss of the pumped medium and maintaining high 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 specific application.
Other Characteristics
Vibration Resistance	Can withstand vibrations with a frequency range of 6 - 55 Hz and an amplitude of 0.5 mm.	Designed to maintain its sealing performance even in industrial environments with significant vibrations.
Self - lubricating Property	The seal faces are coated with a special self - lubricating material, reducing friction and wear during operation.	This self - lubricating feature enhances the seal's durability, reduces energy consumption, and minimizes the need for additional lubrication.
