Product Description

Parameter Category	Specific Parameter	Detailed Description
Basic Information
Seal Type	Queeny-8-B1 Mechanical Seal	A high - performance mechanical seal meticulously designed for industrial pumps, providing reliable sealing solutions across various applications.
Brand	[Insert Brand Here]
Model	Queeny-8-B1	Engineered to meet the demanding requirements of different working conditions, ensuring long - term stable operation.
Materials
- Rotating Ring	Silicon Carbide (SiC)	SiC is utilized for its exceptional hardness and wear - resistance. It can endure high - speed rotation and heavy loads, guaranteeing a prolonged service life under arduous operating conditions.
- Stationary Ring	Aluminum Oxide Ceramic	This material offers excellent corrosion resistance and a smooth surface finish, facilitating efficient sealing and minimizing friction.
- O - Ring	Fluoroelastomer (FKM)	The FKM O - ring provides a tight seal and is highly resistant to a wide range of chemicals and temperatures, ensuring consistent sealing performance.
Size Specifications
Shaft Diameter Range	12 - 38 mm	Compatible with pump shafts within this diameter range, making it suitable for a broad spectrum of pump models.
Seal Chamber Inner Diameter	22 - 48 mm	Designed to fit precisely into seal chambers with inner diameters in this range, ensuring proper installation and optimal performance.
Seal Width	6.5 mm	The carefully calibrated seal width strikes a balance between effective sealing and reduced friction, enhancing overall efficiency.
Performance Parameters
Working Pressure	Maximum 1.4 MPa	Under normal operational scenarios, the seal can withstand a maximum pressure of 1.4 MPa, preventing leakage of the pumped medium.
Working Temperature	-25ºC - 130ºC	Capable of operating effectively within this extensive temperature range, adapting to both extremely cold and moderately high - temperature environments.
Linear Velocity	Maximum 9 m/s	It can handle a maximum linear velocity of 9 m/s, ensuring stable sealing performance even at high rotational speeds.
Applicable Media
- Water - based Fluids	Suitable for clean water, treated water, and various aqueous solutions with a pH range of 4 - 10.
- Oil - based Fluids	Compatible with mineral oils, synthetic lubricants, and certain light oil - based products.
- Chemical Fluids	Resistant to many common acids, alkalis, and 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 procedure to ensure accurate alignment and reliable sealing.
Installation Torque	12 - 18 N·m	During installation, applying a torque within this range is crucial to secure the seal properly without causing damage to the components.
Maintenance Cycle	Every 3500 operating hours	Regular maintenance at this interval is recommended, involving inspection for signs of wear, leakage, and proper component alignment.
Storage Conditions	Store in a dry, cool place with a temperature between 5ºC - 25ºC. Keep away from direct sunlight, moisture, and corrosive substances.	Proper storage conditions preserve the integrity of the seal materials and extend the shelf life.
Quality and Certification
Service Life	Approximately 2 - 3 years under normal operating conditions	With proper operation and maintenance, the Queeny - 8 - B1 seal can provide reliable service for 2 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 system integrity.
Certification Standards	ISO 9001, ISO 14001 (if applicable)	Complies with international quality management and environmental management system standards, guaranteeing product quality and environmental sustainability.
Other Characteristics
Vibration Resistance	Can withstand vibrations with a frequency range of 8 - 45 Hz and an amplitude of 0.3 mm.	Maintains its sealing performance even in environments with moderate vibration levels, ensuring stable operation.
Self - lubricating Property	The seal surfaces are coated with a specialized self - lubricating layer, reducing friction and wear.	This feature extends the service life of the seal and minimizes the need for additional lubrication.
