Detailed Product Description

 (SN/DN) mechanical seals are used for chemical centrifugal pumps, vacuum pumps, compressors and other rotating equipment.


Structural features: single end (SN) and double end (DN), multi spring, balanced, arbitrary rotation, static structural cartridge mechanical seals. This mechanical seal has excellent compensation performance and is suitable for working conditions with sudden changes in system pressure. The compensation ring is placed inside the flange, and the auxiliary seal ring protects the spring at the medium side to ensure that the spring does not contact the medium, thus preventing the medium from corroding the spring. The shaft sleeve has a pumping groove design, and the pin drive is reliable and stable. The mechanical seal is simple and reliable in structure, convenient in installation, compact in axial and radial dimensions, and suitable for replacing packing.

Executive standard: DIN24960, ISO3069, ANSI B73.1M

Application field: widely used in water treatment, power plant, metallurgy, food processing, pharmacy, chemical industry, fertilizer, paper making and other fields. It is applicable to clean water pumps, chemical pumps, double suction pumps, pulp pumps, compressors and other rotating equipment, and can be used for packing transformation.
