Product Description

Parameter Category	Specific Parameter	Detailed Description
Basic Information
Seal Type	M74D Mechanical Seal	A high - performance mechanical seal designed for a wide range of industrial applications, providing reliable sealing solutions for pumps and rotating equipment.
Brand	[Brand Name]
Model	M74D	This model is engineered to meet the demanding requirements of various operating conditions, ensuring long - term stability and efficiency.
Materials
- Rotating Ring	Silicon Carbide (SiC)	Silicon Carbide offers excellent hardness and wear resistance, making it ideal for withstanding high - speed rotation and heavy loads, thus extending the service life of the seal.
- Stationary Ring	Tungsten Carbide	Tungsten Carbide provides superior mechanical strength and corrosion resistance, ensuring a stable sealing surface under different media conditions.
- O - Ring	Fluoroelastomer (FKM)	The FKM O - ring ensures a tight seal and is resistant to a broad spectrum of chemicals, as well as temperature variations, maintaining its elasticity and sealing performance.
Size Specifications
Shaft Diameter Range	25 - 60 mm	Suitable for shafts with diameters within this range, allowing for compatibility with a variety of pump shaft sizes in different industrial setups.
Seal Chamber Inner Diameter	35 - 70 mm	Designed to fit into seal chambers with inner diameters in this range, ensuring proper installation and alignment for optimal sealing performance.
Seal Width	9 mm	The 9 - mm width is carefully selected to balance sealing effectiveness and frictional resistance, reducing energy consumption while maintaining a reliable seal.
Performance Parameters
Working Pressure	Maximum 2.0 MPa	Under normal operating conditions, the M74D seal can withstand a maximum pressure of 2.0 MPa, preventing leakage of the pumped medium and ensuring system integrity.
Working Temperature	-25ºC - 180ºC	Capable of operating effectively within this wide temperature range, making it suitable for applications in both cold - storage facilities and high - temperature industrial processes.
Linear Velocity	Maximum 12 m/s	The seal can handle a maximum linear velocity of 12 m/s, enabling it to perform well in high - speed rotating equipment without compromising on sealing quality.
Applicable Media
- Water - based Fluids	Ideal for clean water, cooling water, and various water - based chemical solutions with a pH range of 2 - 13.
- Oil - based Fluids	Compatible with lubricating oils, hydraulic oils, and many petroleum - based products, ensuring reliable operation in oil - related industries.
- Chemical Liquids	Resistant to a variety of common chemicals, such as alkalis, weak acids, and solvents, making it suitable for chemical processing applications.
Installation and Maintenance
Installation Method	Axial Installation	Installed axially onto the pump shaft following a precise installation procedure to ensure correct positioning and alignment of all seal components.
Installation Torque	18 - 22 N·m	During installation, a torque within this range should be applied to secure the seal properly, avoiding over - tightening or under - tightening that could lead to seal failure.
Maintenance Cycle	Every 4000 operating hours	Regular maintenance is recommended every 4000 operating hours, including inspection for signs of wear, leakage, and proper functioning of the seal components.
Storage Conditions	Store in a dry, well - ventilated area at a temperature between 5ºC - 25ºC. Keep away from direct sunlight, moisture, and corrosive substances.	Proper storage conditions help preserve the quality of the seal materials and prevent premature degradation.
Quality and Certification
Service Life	Approximately 2 - 3 years under normal operating conditions	With proper operation and maintenance, the M74D seal can provide reliable service for 2 - 3 years, reducing downtime and maintenance costs.
Leakage Rate	≤0.05 mL/h	Engineered to have an extremely low leakage rate, ensuring minimal loss of the pumped medium and meeting strict environmental and safety standards.
Certification Standards	ISO 9001, ISO 14001, and industry - specific certifications (e.g., API for oil and gas applications)	Meets international quality management and environmental management system standards, as well as relevant industry - specific requirements, ensuring high - quality performance and compliance.
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 integrity even in environments with significant vibrations, ensuring stable operation of the equipment.
Self - lubricating Property	The seal faces are treated with a special self - lubricating coating, reducing friction and wear between the mating surfaces.	This self - lubricating feature enhances the seal's durability and reduces the need for additional lubrication during operation.
