Product Description

Parameter	Value	Description
Model	Seal-M7N	Unique identification for the mechanical seal model
Seal Type	Single Spring Unbalanced	Design type featuring a single compression spring, unbalanced design suitable for general - purpose applications
Material - Seal Face	Tungsten Carbide/Carbon Graphite	Hard - facing material (tungsten carbide) paired with a softer carbon graphite face for effective sealing and wear resistance
Material - Spring	Stainless Steel 316	High - corrosion - resistance spring material, suitable for a wide range of chemical environments
Material - O - Ring	Ethylene Propylene Diene Monomer (EPDM)	O - ring material offering good resistance to water, steam, and many polar substances
Operating Pressure	0 - 1.6 MPa	Maximum and minimum pressure range the seal can effectively operate under. Values above 1.6 MPa may cause seal failure
Operating Temperature	- 40°C to 150°C	Temperature range within which the seal maintains its integrity and performance. Extreme temperatures outside this range can degrade materials
Shaft Diameter Range	20 mm - 80 mm	Diameter range of the shafts for which the Seal - M7N is compatible
Speed Limit	Up to 2500 RPM	Maximum rotational speed of the shaft to ensure proper sealing and prevent excessive wear
Media Compatibility	Water, Aqueous Solutions, Non - aggressive Chemicals	Types of fluids the seal is designed to handle. Not suitable for highly corrosive or abrasive media without additional protection
Seal Face Flatness	≤ 0.0009 mm	Precision of the seal face flatness to ensure a tight seal and prevent leakage
Spring Rate	50 N/mm	The force exerted by the spring per unit of compression, affecting the seal's contact pressure
Axial Length	35 mm	The length of the seal along the axis of the shaft, important for installation and space considerations
Radial Thickness	12 mm	The thickness of the seal in the radial direction, contributing to its structural integrity
Installation Torque	15 - 20 N·m	Recommended torque for installing the mechanical seal to ensure proper seating and performance
Leakage Rate	≤ 5 ml/h	Maximum allowable leakage rate under normal operating conditions, indicating the seal's effectiveness
Dynamic Friction Coefficient	0.15 - 0.25	Measure of the friction between the seal faces during operation, affecting energy consumption and wear
Static Friction Coefficient	0.2 - 0.3	Measure of the friction between the seal faces when the shaft is stationary
Vibration Limit	≤ 5 mm/s	Maximum allowable vibration level to prevent seal damage and maintain proper sealing performance
Lubrication Requirement	Fluid - Lubricated	The seal relies on the process fluid for lubrication between the seal faces
Mounting Orientation	Any	The seal can be mounted in any orientation (horizontal, vertical, etc.) without affecting its performance
Certification	ISO 9001:2015	Quality management system certification ensuring consistent product quality

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.
