Product Description

Parameter Category	Specific Parameter	Detailed Description
Basic Information
Seal Type	QT - 606 Mechanical Seal	A high - performance mechanical seal designed for a wide range of industrial pump applications, ensuring reliable sealing and stable operation.
Brand	[Insert Brand Name]
Model	QT - 606	This model is engineered to meet the demanding requirements of various fluid handling systems.
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 with minimal wear.
- Stationary Ring	Silicon Nitride	Silicon nitride offers excellent corrosion resistance and low friction, contributing to the overall efficiency and longevity of the seal.
- O - Ring	Fluoroelastomer (FKM)	The FKM O - ring ensures a tight seal and is resistant to a broad spectrum of chemicals and temperature variations, maintaining reliable performance.
Size Specifications
Shaft Diameter Range	25 - 60 mm	The seal is compatible with pump shafts within this diameter range, making it suitable for numerous pump models in different industries.
Seal Chamber Inner Diameter	35 - 70 mm	Designed to fit into seal chambers with inner diameters in this range, guaranteeing proper installation and optimal sealing performance.
Seal Width	10 mm	The 10 - mm seal width is carefully calibrated to balance effective sealing and reduced frictional forces, enhancing the seal's operational efficiency.
Performance Parameters
Working Pressure	Maximum 2.0 MPa	Under normal operating conditions, the QT - 606 seal can withstand a maximum pressure of 2.0 MPa, preventing leakage of the pumped medium.
Working Temperature	-30ºC - 180ºC	It can operate effectively within this wide temperature range, adapting to both extremely cold and high - temperature industrial environments.
Linear Velocity	Maximum 12 m/s	Capable of handling a maximum linear velocity of 12 m/s, the seal ensures stable performance even at high rotational speeds of the pump shaft.
Applicable Media
- Water - based Fluids	Suitable for clean water, cooling water, and various aqueous solutions with pH values ranging from 2 to 13.
- Oil - based Fluids	Compatible with lubricating oils, gear oils, and many types of hydraulic oils commonly used in industrial machinery.
- Chemical Fluids	Resistant to a variety of weak acids, alkalis, and organic solvents, but specific compatibility should be verified based on the actual chemical composition.
Installation and Maintenance
Installation Method	Axial Installation	Installed axially onto the pump shaft following a standardized installation procedure to ensure correct alignment and a secure seal.
Installation Torque	18 - 25 N·m	During installation, a torque within this range should be applied to firmly secure the seal without causing damage to its components.
Maintenance Cycle	Every 4000 operating hours	Regular maintenance every 4000 operating hours is recommended. This includes inspecting the seal for signs of wear, checking for leakage, and ensuring proper alignment.
Storage Conditions	Store in a dry, dust - free environment at a temperature between 5ºC - 25ºC. Keep away from direct sunlight and strong electromagnetic fields.	Proper storage conditions help preserve the integrity of the seal materials 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 - 606 seal can provide reliable service for 2 to 3.5 years.
Leakage Rate	≤0.05 mL/h	Engineered to have an extremely low leakage rate, the seal ensures minimal loss of the pumped fluid and enhanced environmental protection.
Certification Standards	ISO 9001, ISO 14001, and industry - specific certifications (e.g., API 682 for certain applications)	Complies with international quality management and environmental management system standards, as well as relevant industry - specific requirements.
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 moderate to high levels of vibration, common in industrial settings.
Self - lubricating Property	The seal surfaces are treated with a special self - lubricating coating, reducing friction and wear during operation.	This self - lubricating feature extends the seal's service life and reduces the need for frequent lubrication, lowering maintenance costs.
