M7N/M74N-20/25/30/35/40/45/50/55/60/65/70/75/80 Fluorocarbon Alloy Mechanical Seal
Product Introduction
In modern industrial production, the reliability of mechanical seals directly impacts equipment operational efficiency and production safety. The M7N/M74N series mechanical seals, with their outstanding technical performance and broad applicability, have become the primary sealing products in industries such as petroleum, chemical processing, and pharmaceuticals.
This series employs an optimised balanced structure design, incorporating high-hardness carbide seal rings and high-performance fluororubber seals. Its unique friction design not only delivers outstanding wear resistance but also effectively handles minute particles within the medium, significantly extending service life.
The range employs standardised design with shaft diameter specifications spanning 20mm to 80mm, accommodating diverse equipment requirements. Suitable for centrifugal pumps, reactors, agitators and other rotating machinery, these seals find extensive application across refining, chemical processing, pharmaceutical manufacturing and food processing sectors. They deliver reliable sealing assurance whether conveying clean water, petroleum products or handling corrosive media. Each seal undergoes rigorous performance testing and quality inspection to ensure optimal condition upon delivery.
Features
1. Core Technical Advantages
This series of seals employs an optimised balanced structure design, incorporating high-hardness cemented carbide sealing rings and high-performance fluororubber seals. This combination ensures stable operation at working pressures up to 1.6MPa. Its unique friction pair design not only delivers outstanding wear resistance but also effectively handles minute particles within the medium, significantly extending service life.
2. Exceptional Material Properties
The core sealing components utilise specially treated carbide, guaranteeing intact sealing surfaces even under severe operating conditions. The fluororubber seals exhibit outstanding chemical resistance, withstanding corrosion from most oils, acids, and organic solvents. This material combination maintains excellent elasticity while delivering superior mechanical strength.
3. Innovative Design Features
The series employs standardised design with shaft diameters ranging from 20mm to 80mm, accommodating diverse equipment requirements. A unique anti-rotation mechanism effectively prevents relative displacement during operation, ensuring perfect seal face contact. Its compact structure facilitates effortless installation in confined spaces, significantly enhancing maintenance efficiency.
