Product Description

Parameter Category	Specific Parameter	Detailed Description
Basic Information
Seal Type	Queeny-EH Mechanical Seal	A high - performance mechanical seal designed for demanding industrial applications, providing reliable and long - lasting sealing solutions.
Model	Queeny-EH	Engineered to meet the needs of various pumps and operating conditions, ensuring efficient operation.
Materials
- Rotating Ring	Tungsten Carbide	Tungsten carbide offers extreme hardness and excellent wear resistance, allowing the rotating ring to endure high - speed and high - pressure operations, significantly extending the seal's lifespan.
- Stationary Ring	Silicon Nitride	Silicon nitride provides good corrosion resistance, high mechanical strength, and a smooth surface, which are crucial for effective sealing and reducing friction.
- O - Ring	Ethylene Propylene Diene Monomer (EPDM)	EPDM O - ring has excellent resistance to water, steam, and many chemicals. It also offers good sealing performance across a wide temperature range.
Size Specifications
Shaft Diameter Range	18 - 45 mm	This seal can be installed on pump shafts with diameters within this range, making it suitable for a diverse range of pump models.
Seal Chamber Inner Diameter	28 - 55 mm	Designed to fit into seal chambers with inner diameters in this interval, ensuring proper installation and optimal sealing performance.
Seal Width	8 mm	The 8 - mm width of the seal is optimized to balance effective sealing and reduced frictional forces, enhancing the overall efficiency of the pumping system.
Performance Parameters
Working Pressure	Maximum 1.5 MPa	Under normal operating conditions, the Queeny - EH seal can withstand a maximum working pressure of 1.5 MPa, preventing leakage of the pumped medium and maintaining system integrity.
Working Temperature	-30ºC - 130ºC	Capable of operating effectively within this temperature range, it can adapt to both cold and moderately high - temperature industrial processes.
Linear Velocity	Maximum 10 m/s	The seal is engineered to handle a maximum linear velocity of 10 m/s, ensuring stable performance even at high - speed pump operations.
Applicable Media
- Water - based Fluids	Suitable for clean water, demineralized water, and various aqueous solutions with a pH range of 4 - 10. It can handle both slightly acidic and alkaline water - based media.
- Oil - based Fluids	Applicable to common mineral oils, synthetic lubricating oils, and some hydraulic oils. It provides reliable sealing for oil - circulation systems.
- Chemical Solutions	Resistant to many common chemical solutions, such as weak acids, alkalis, and some non - aggressive organic solvents, making it suitable for certain chemical processing applications.
Installation and Maintenance
Installation Method	Axial Installation	The seal is installed axially onto the pump shaft following a specific installation procedure to ensure proper alignment and a tight seal.
Installation Torque	10 - 15 N·m	During installation, a torque within this range should be applied to secure the seal in place without over - tightening, which could damage the seal components.
Maintenance Cycle	Every 3500 operating hours	Regular maintenance is recommended every 3500 operating hours. This includes inspecting the seal for signs of wear, leakage, and proper alignment. Timely replacement or adjustment can prevent potential failures.
Storage Conditions	Store in a dry, dark environment at a temperature between 0ºC - 30ºC. Keep away from direct sunlight, heat sources, and corrosive gases.	Proper storage helps maintain the quality and integrity of the seal components, ensuring their performance when installed.
Quality and Certification
Service Life	Approximately 1.5 - 2.5 years under normal operating conditions	With proper operation and maintenance, the Queeny - EH mechanical seal can provide reliable service for 1.5 to 2.5 years, reducing maintenance costs.
Leakage Rate	≤0.08 mL/h	The seal is designed to have a low leakage rate, ensuring that the pumped medium remains within the system, minimizing the risk of environmental pollution and product loss.
Certification Standards	ISO 9001, ISO 14001	The Queeny - EH seal complies with ISO 9001 quality management system standards and ISO 14001 environmental management system standards, demonstrating its high - quality and environmental - friendly features.
Other Characteristics
Vibration Resistance	Can withstand vibrations with a frequency range of 5 - 45 Hz and an amplitude of 0.4 mm.	Engineered to maintain its sealing performance in environments with moderate vibration levels, ensuring stable operation of the pumping equipment.
Self - lubricating Property	The seal surfaces are treated with a special self - lubricating material to reduce friction and wear.	This self - lubricating feature helps to extend the service life of the seal and improve the overall efficiency of the pumping system by reducing energy consumption.
