Product Description

Parameter Category	Specific Parameter	Detailed Description
Basic Information
Seal Type	QT-M7N Mechanical Seal	A high-performance mechanical seal designed for industrial pumps, providing reliable sealing solutions across various applications.
Model	QT-M7N	Engineered to offer stable operation and long service life under different working conditions.
Materials
- Rotating Ring	Silicon Carbide (SiC)	Renowned for its high hardness and superior wear resistance, the SiC rotating ring ensures durability even in high-speed and high-pressure scenarios.
- Stationary Ring	Tungsten Carbide	Tungsten carbide stationary ring provides excellent mechanical strength and corrosion resistance, contributing to effective sealing.
- O-Ring	Fluoroelastomer (FKM)	FKM O-ring offers tight sealing and resistance to a wide range of chemicals and temperatures.
Size Specifications
Shaft Diameter Range	12 - 35 mm	Suitable for installation on pump shafts with diameters within this range, catering to diverse pump sizes.
Seal Chamber Inner Diameter	22 - 45 mm	Designed to fit precisely into seal chambers with inner diameters in this dimension range for proper installation.
Seal Width	6.5 mm	Optimized seal width balances sealing efficiency and reduces friction for enhanced performance.
Performance Parameters
Working Pressure	Maximum 1.5 MPa	Maintains reliable sealing performance under a maximum working pressure of 1.5 MPa to prevent medium leakage.
Working Temperature	-25ºC - 130ºC	Capable of operating effectively within this broad temperature range, adapting to cold and moderately high-temperature environments.
Linear Velocity	Maximum 9 m/s	Ensures stable operation even at a high linear velocity of up to 9 m/s.
Applicable Media
- Water-based Fluids	Suitable for fresh water, process water, and aqueous solutions with pH values ranging from 4 to 10.
- Oil-based Fluids	Compatible with mineral oils, synthetic lubricants, and certain petroleum-based fluids.
- Chemical Fluids	Resistant to weak acids, alkalis, and some organic solvents.
Installation and Maintenance
Installation Method	Axial Installation	Installed axially onto the pump shaft following a standardized procedure to ensure correct alignment and sealing integrity.
Installation Torque	12 - 17 N·m	Recommended torque range during installation to securely fasten the seal without causing damage.
Maintenance Cycle	Every 4000 operating hours	Regular inspection and maintenance every 4000 hours to check for wear, leakage, and proper functioning.
Storage Conditions	Store in a dry place at temperatures between 5ºC - 25ºC, away from direct sunlight and corrosive substances.	Proper storage conditions preserve the seal's material properties and extend its shelf life.
Quality and Certification
Service Life	Approximately 2 - 3 years under normal operating conditions	With proper operation and maintenance, the QT-M7N seal can serve reliably for 2 to 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 the requirements of 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.	Designed to maintain sealing performance in environments with moderate vibration levels.
Self-lubricating Property	Seal surfaces are treated with a self-lubricating coating to minimize friction and wear.	The self-lubricating feature extends the seal's lifespan and reduces maintenance needs.

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.
