Description

Basic Features - Structure: Single End - Pressure: Medium Pressure Mechanical Seals - Speed: High Speed Mechanical Seal - Temperature: General Temperature Mechanical Seal - Performance: Wear - Standard: DIN24960, ISO3069, and GB6556 - Model NO.: M7N, M74, M74D (2 M74 Seals) - Balance: Unbalanced - Specification: Inner Diameter: 20 mm to 300 mm Product Detailed Description M7N, AKA M74 Mechanical Seal for Chemical Centrifugal Pumps, KSB/Kaiquan Water Pumps and Double Suction Pumps Structural Features: single end, wave spring (M7N), multi springs (M74), unbalanced, independent direction of rotation, lug transmission. M7N has a simple way of transmission and good compatibility; the wave spring structure allows transferring particulate, crystalized and high viscosity content. M74 also has a simple way of transmission and the compensation components are pre-assembled; it is easy to install and has good compensation. The load on the seal faces are balanced and the sealing performance is stable and reliable. The default design of M7N/M74 are using square lug transmission, which according to the feedback of users, would be possible to cause the damage of the rotary seal ring or the square lug itself. YALAN Seals optimized the design of the lug here with a new model named M74R, with a rounded corner lug, reducing the risks of damaging the seal rings and the lug by over 70%. Industrial Standards: DIN24960, ISO3069, and GB6556 Scopes of Application: widely used in chemical processing, oil refining, petrochemical engineering, sewage treatment, pharmacy and food production.
