Product Description

Parameter Category	Specific Parameter	Detailed Description
Basic Information
Seal Type	QT 8-1 Mechanical Seal	A high - performance mechanical seal designed for industrial pumps, providing reliable sealing solutions for various applications.
Model	QT 8-1	Engineered to meet the demanding requirements of modern pumping systems.
Materials
- Rotating Ring	Silicon Carbide (SiC)	Offers excellent hardness and wear resistance, ensuring long - term durability under high - speed and high - pressure conditions.
- Stationary Ring	Aluminum Oxide Ceramic	Features superior corrosion resistance and a smooth surface for efficient sealing.
- O - Ring	Fluoroelastomer (FKM)	Provides a tight seal and is resistant to a wide range of chemicals and temperatures.
Size Specifications
Shaft Diameter Range	12 - 35 mm	Compatible with pump shafts within this diameter range, suitable for different pump models.
Seal Chamber Inner Diameter	22 - 45 mm	Designed to fit into seal chambers with inner diameters in this range for proper installation.
Seal Width	6.5 mm	Optimized width for effective sealing while minimizing friction.
Performance Parameters
Working Pressure	Maximum 1.5 MPa	Capable of withstanding up to 1.5 MPa of pressure to prevent medium leakage.
Working Temperature	-25ºC - 130ºC	Operates efficiently within this temperature range, adapting to both cold and hot working environments.
Linear Velocity	Maximum 9 m/s	Ensures stable sealing performance even at high rotational speeds of up to 9 m/s.
Applicable Media
- Water - based Fluids	Suitable for clean water, process water, and aqueous solutions with pH values from 4 to 10.
- Oil - based Fluids	Applicable to mineral oils, synthetic lubricants, and some petroleum - based products.
Installation and Maintenance
Installation Method	Axial Installation	Installed axially onto the pump shaft following a standardized procedure for correct alignment.
Installation Torque	12 - 18 N·m	Recommended torque range during installation to secure the seal without causing damage.
Maintenance Cycle	Every 4000 operating hours	Regular inspection and maintenance are advised every 4000 hours of operation to check for wear and leakage.
Storage Conditions	Store in a dry place at 5ºC - 25ºC, away from direct sunlight and chemicals.	Proper storage conditions preserve the seal's integrity and extend its shelf life.
Quality and Certification
Service Life	Approximately 2 - 3 years under normal operating conditions	With proper operation and maintenance, the seal can last for 2 - 3 years.
Leakage Rate	≤0.05 mL/h	Engineered to have a low leakage rate, ensuring minimal loss of the pumped medium.
Certification Standards	ISO 9001, ISO 14001	Meets international quality management (ISO 9001) and environmental management (ISO 14001) standards.
Other Characteristics
Vibration Resistance	Can withstand vibrations with a frequency range of 6 - 45 Hz and an amplitude of 0.35 mm.	Maintains sealing performance in environments with moderate vibration levels.
Self - lubricating Property	Seal surfaces are treated with a self - lubricating coating to reduce friction and wear.	This feature enhances the seal's lifespan and operational efficiency.

 

Queeny design engineers are able to produce a seals solution for the most basic applications,to those that are extremely complicated and unique. We are able to provide you these solutions supported by life test data and years of excellent field performance.As your partner, we provide sealing solutions for centrifugal pumps,agitators and other rotating equipment, and help you consolidate your brand and market position.

Mechanical sealing adopts the principle of mechanical friction sealing, which has excellent sealing performance, which can effectively prevent leakage and protect the safety of the environment and equipment. Compared with traditional packing seals and rotary seals, the sealing effect of mechanical seals is more reliable.

 

Our products are made of high quality materials and manufacturing processes, with a long service life and low cost of use. It can effectively reduce the maintenance costs and operating costs of equipment .

 

Our mechanical seals are designed to be easy to service and replace,simply by removing the sealing components and replacing the sealing surface and sealing ring. Compared with other sealing forms, our products are more convenient to repair and replace.

 

Mechanical seal is suitable for high temperature, low temperature, high pressure, vacuum and corrosive media and other complex environment, to ensure the stable operation of the equipment.
