Product Description

Parameter Category	Specific Parameter	Detailed Description
Basic Information
Seal Type	Qt-502 Mechanical Seal	A high-performance mechanical seal designed for a wide range of industrial pumping applications, ensuring reliable operation and minimal leakage.
Brand	[Insert Brand Name]
Model	Qt-502	This model is engineered to meet the demanding requirements of various fluid-handling systems.
Materials
- Rotating Ring	Silicon Carbide (SiC)	SiC provides excellent wear resistance and high hardness, enabling the rotating ring to endure harsh operating conditions, such as high speeds and pressures, and maintain its integrity over time.
- Stationary Ring	Tungsten Carbide	Tungsten carbide offers superior hardness and chemical resistance, ensuring a stable and long-lasting seal surface in contact with the rotating ring.
- O-Ring	Fluoroelastomer (FKM)	The FKM O-ring ensures a tight and reliable seal, with good resistance to a variety of chemicals, oils, and temperature fluctuations.
Size Specifications
Shaft Diameter Range	25 - 60 mm	Suitable for installation on pump shafts with diameters within this range, providing flexibility for different pump models and sizes.
Seal Chamber Inner Diameter	35 - 70 mm	Designed to fit snugly into seal chambers with inner diameters in this range, ensuring proper alignment and optimal sealing performance.
Seal Width	9 mm	The 9 mm width of the seal is carefully calculated to balance effective sealing force and reduced friction, enhancing the overall efficiency of the pump system.
Performance Parameters
Working Pressure	Maximum 2.0 MPa	Under normal operating conditions, the Qt-502 seal can withstand a maximum pressure of 2.0 MPa, preventing leakage of the pumped fluid and ensuring system integrity.
Working Temperature	-25ºC - 180ºC	Capable of operating efficiently within this wide temperature range, making it suitable for applications in both cold and high-temperature environments.
Linear Velocity	Maximum 12 m/s	The seal is engineered to handle a maximum linear velocity of 12 m/s, allowing it to function reliably even in high-speed pumping operations.
Applicable Media
- Water and Aqueous Solutions	Ideal for use with clean water, process water, and various aqueous solutions with a pH range of 2 - 13.
- Oil-based Fluids	Compatible with mineral oils, synthetic lubricants, and most hydraulic fluids commonly used in industrial applications.
- Chemical Liquids	Resistant to many common chemicals, such as acids, alkalis, and solvents, within the specified temperature and pressure limits.
Installation and Maintenance
Installation Method	Axial Installation	Installed axially onto the pump shaft following a precise installation procedure to ensure correct positioning and proper sealing.
Installation Torque	18 - 22 N·m	Apply a torque within this range during installation to secure the seal firmly without causing damage to the seal components.
Maintenance Cycle	Every 4000 operating hours	Regular maintenance is recommended every 4000 operating hours. This includes inspecting the seal for signs of wear, checking for leakage, and ensuring proper alignment of the pump components.
Storage Conditions	Store in a dry, dust-free environment at temperatures between 5ºC - 25ºC. Avoid exposure to direct sunlight and corrosive gases.	Proper storage conditions help preserve the quality and performance of the seal, extending its shelf life.
Quality and Certification
Service Life	Approximately 2 - 3.5 years under normal operating conditions	With proper operation and maintenance, the Qt-502 seal can provide reliable service for 2 - 3.5 years, reducing the frequency of replacement and maintenance costs.
Leakage Rate	≤0.05 mL/h	Engineered to have an extremely low leakage rate, minimizing fluid loss and ensuring compliance with strict environmental and safety standards.
Certification Standards	ISO 9001, ISO 14001, and API 682 (if applicable)	The seal meets the rigorous requirements of international quality management (ISO 9001), environmental management (ISO 14001), and may comply with API 682 standards for mechanical seals in the petroleum, petrochemical, and chemical industries.
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 environments with significant vibration, ensuring stable operation of the pump system.
Self-lubricating Property	The seal faces are treated with a special self-lubricating coating, reducing friction and wear.	This self-lubricating feature not only extends the service life of the seal but also improves the overall efficiency of the pump by reducing energy consumption.

Queeny design engineers are able to produce a seals solution for the most basic applications,to those that are extremely complicated and unique.
