Product Description

Parameter Category	Specific Parameter	Detailed Description
Basic Information
Seal Type	QT BEL02-101 Mechanical Seal	A specialized mechanical seal designed for industrial pump applications, providing efficient sealing performance.
Model	QT BEL02-101	Specifically engineered to meet the demands of various pumping systems in different working conditions.
Materials
- Rotating Ring	Silicon Carbide (SiC)	SiC offers high hardness and excellent wear resistance, ensuring durability and long - term performance under high - speed rotation and pressure.
- Stationary Ring	Tungsten Carbide	Tungsten carbide provides a smooth and hard surface, enhancing the sealing efficiency and resistance to corrosion.
- O - Ring	Fluoroelastomer (FKM)	FKM O - ring ensures a tight seal and has good resistance to a wide range of chemicals and temperatures.
Size Specifications
Shaft Diameter Range	25 - 55 mm	Suitable for pump shafts with diameters within this range, allowing for versatile installation across different pump models.
Seal Chamber Inner Diameter	35 - 65 mm	Designed to fit into seal chambers with inner diameters in this range for proper positioning and operation.
Seal Width	9 mm	The 9 - mm width optimizes the balance between effective sealing and minimizing frictional forces.
Performance Parameters
Working Pressure	Maximum 1.8 MPa	Capable of withstanding a maximum working pressure of 1.8 MPa to prevent leakage of the pumped medium.
Working Temperature	-25ºC - 160ºC	Operates effectively within this temperature range, making it suitable for both cold - and high - temperature industrial applications.
Linear Velocity	Maximum 12 m/s	Can handle a maximum linear velocity of 12 m/s, ensuring stable performance even at high - speed pump operations.
Applicable Media
- Water - based Solutions	Suitable for pure water, process water, and water - based chemical solutions with a pH range of 2 - 13.
- Oil - based Fluids	Compatible with mineral oils, synthetic lubricants, and some light oil - based chemicals.
Installation and Maintenance
Installation Method	Axial Installation	Installed axially onto the pump shaft following a precise installation procedure to ensure correct alignment and reliable sealing.
Installation Torque	18 - 22 N·m	An installation torque within this range is required to secure the seal properly without causing damage to the components.
Maintenance Cycle	Every 4000 operating hours	Regular maintenance is recommended every 4000 operating hours, including inspection for wear, leakage, and proper functioning.
Storage Conditions	Store in a dry, cool place with a temperature range of 5ºC - 25ºC. Avoid exposure to sunlight and chemical vapors.	Proper storage conditions help maintain the integrity of the seal materials and extend its shelf life.
Quality and Certification
Service Life	Approximately 2 - 3.5 years under normal operating conditions	With proper operation and maintenance, the QT BEL02-101 seal can provide reliable service for 2 - 3.5 years.
Leakage Rate	≤0.12 mL/h	Engineered to have a low leakage rate, ensuring minimal loss of the pumped medium and maintaining system integrity.
Certification Standards	ISO 9001, ISO 14001	Meets the requirements of ISO 9001 quality management system and ISO 14001 environmental management system standards.
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 sealing performance in environments with significant vibrations.
Self - lubricating Property	The seal faces are treated with a self - lubricating coating to reduce friction and wear, improving overall 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.
