Product Description

Product Description

 

The core design of the M7N adheres to German DIN24960 and international EN12756 standards, giving it excellent versatility and interchangeability. It is a single-end, unbalanced, wave-spring-loaded mechanical seal capable of arbitrary rotation. Simply put, it is well-designed to adapt to a variety of common operating conditions, and installation is very convenient as it does not require differentiation of the pump's rotation direction.

Scope of application	Chemical plants, pumping plants, sewage plants

Main Material Combinations

To adapt to different media, the materials of the M7N seal can be flexibly combined:

Components | Optional Materials

Sealing Face (Dynamic Ring & Stationary Ring): Graphite, Silicon Carbide (SiC), Tungsten Carbide (TC/Alloy), Alumina Ceramic (Cer), etc.

Auxiliary Seals (O-rings): Nitrile Rubber (NBR), Fluororubber (FKM/Viton), Ethylene Propylene Dioxide Rubber (EPDM), Polytetrafluoroethylene (PTFE), etc.

Metal Components (Springs, Push Rings, etc.): 304 Stainless Steel, 316 Stainless Steel, etc.

For example, when conveying clean water, a typical combination is graphite with silicon carbide; while when treating wastewater containing particles, a combination of silicon carbide with silicon carbide may be needed to increase wear resistance.

 

 

Design Features and Advantages

Beyond standard parameters, the M7N seal incorporates several clever design features to enhance reliability and durability:

Anti-detachment design: The push ring features a transmission catch that effectively prevents the spring from falling off, simplifying installation.

Wear limiting protection: The stationary ring provides a limiting function, restricting the spring's travel and effectively preventing excessive wear on the sealing face (such as the carbon ring).

Floating stationary ring: The floating design of the stationary ring better compensates for radial runout and vibration of the pump shaft, ensuring a more stable seal.

Typical Applications

Due to its excellent versatility and reliability, the M7N seal is widely used across various industries:

Applicable pump types: Commonly found in various centrifugal pumps, chemical pumps, pipeline pumps, sewage pumps, pulp pumps, circulating pumps, and slurry pumps.

Applicable media: Clean water, sewage, oils, organic solvents, mildly corrosive chemicals, salt solutions, etc.

Applicable industries: Widely used in water treatment, petrochemicals, papermaking, fertilizers, pharmaceuticals, food and other industries.
