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. 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.

| Materials | Alloy, silicon carbide, graphite, FKM (Customizable) |
| Scope | Chemical plants, pumping plants, sewage plants |
To adapt to different media, the materials of the M7N seal can be flexibly combined:
Anti-detachment design: The push ring features a transmission catch that effectively prevents the spring from falling off.
Wear limiting protection: The stationary ring restricts the spring's travel, preventing excessive wear on the sealing face.
Floating stationary ring: Better compensates for radial runout and vibration of the pump shaft.
Pump types: Centrifugal pumps, chemical pumps, pipeline pumps, sewage pumps, pulp pumps, circulating pumps, and slurry pumps.
Industries: Water treatment, petrochemicals, papermaking, fertilizers, pharmaceuticals, and food industries.
