Product Description

Parameter Category	Specific Parameter	Detailed Description
Basic Information
Seal Type	QT HJ Mechanical Seal	A high - performance mechanical seal designed for industrial pumps and equipment, providing reliable sealing solutions in various working conditions.
Model	QT HJ	Specifically engineered to meet the demands of heavy - duty applications, ensuring long - term stability and durability.
Materials
- Rotating Ring	Silicon Carbide (SiC)	SiC offers excellent hardness and wear resistance, enabling the rotating ring to withstand high - speed rotation and heavy loads without significant wear, thus extending the seal's lifespan.
- Stationary Ring	Tungsten Carbide	Tungsten carbide provides superior mechanical strength and corrosion resistance, ensuring a stable sealing interface with the rotating ring.
- O - Ring	Fluoroelastomer (FKM)	FKM O - ring ensures a tight seal and is resistant to a wide range of chemicals, oils, and high temperatures, maintaining its elasticity and sealing performance over time.
Size Specifications
Shaft Diameter Range	25 - 60 mm	This seal can be installed on shafts with diameters within this range, making it suitable for a variety of pump sizes and applications.
Seal Chamber Inner Diameter	35 - 70 mm	Designed to fit into seal chambers with inner diameters in this range, ensuring proper installation and a secure fit for optimal sealing performance.
Seal Width	9 mm	The 9 - mm width of the seal is optimized to provide a large contact area for effective sealing while minimizing friction and energy consumption.
Performance Parameters
Working Pressure	Maximum 2.0 MPa	Under normal operating conditions, the QT HJ seal can withstand a maximum pressure of 2.0 MPa, preventing leakage of the pumped medium and maintaining system integrity.
Working Temperature	-25ºC - 180ºC	Capable of operating effectively within this wide temperature range, making it suitable for applications in cold storage facilities as well as high - temperature industrial processes.
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 rotating equipment.
Applicable Media
- Water - based Fluids	Suitable for fresh water, seawater, and various water - based chemical solutions with pH values ranging from 2 to 13.
- Oil - based Fluids	Compatible with lubricating oils, gear oils, and most hydraulic oils commonly used in industrial machinery.
- Chemical Fluids	Resistant to many organic solvents, weak acids, and alkalis, making it suitable for a wide range of chemical processing applications.
Installation and Maintenance
Installation Method	Axial Installation	Installed axially onto the pump shaft following a precise installation procedure to ensure correct alignment and proper seating of all seal components.
Installation Torque	18 - 22 N·m	Apply a torque within this range during installation to secure the seal firmly in place without over - tightening, which could damage the seal or the shaft.
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 damage, as well as checking the alignment and condition of the mating surfaces.
Storage Conditions	Store in a dry, cool environment with a temperature range of 5ºC - 25ºC. Keep away from direct sunlight, moisture, and corrosive substances.	Proper storage conditions help preserve the quality and performance of the seal components, ensuring they are in optimal condition when installed.
Quality and Certification
Service Life	Approximately 2 - 3.5 years under normal operating conditions	With proper operation and regular maintenance, the QT HJ seal can provide reliable service for 2 to 3.5 years, reducing downtime and replacement costs.
Leakage Rate	≤0.05 mL/h	Engineered to have an extremely low leakage rate, ensuring minimal loss of the pumped medium and meeting strict environmental and safety requirements.
Certification Standards	ISO 9001, ISO 14001	Complies with international quality management (ISO 9001) and environmental management (ISO 14001) standards, demonstrating its quality and environmental friendliness.
Other Characteristics
Vibration Resistance	Can withstand vibrations with a frequency range of 10 - 60 Hz and an amplitude of 0.6 mm.	Designed to maintain its sealing performance in environments with significant vibrations, common in industrial machinery.
Self - lubricating Property	The seal surfaces are treated with a self - lubricating coating, reducing friction between the rotating and stationary rings and minimizing wear.	This self - lubricating feature enhances the seal's efficiency and extends its service life, reducing the need for frequent maintenance and lubrication.
