AS ZGJ
Single end, multiple springs, balanced cartridge mechanical seal with spring protector and independent direction of rotation. The compensation components support the sleeve while springs remain isolated from the medium, preventing jamming from high viscosity and crystallization. Easy installation without disassembling the seal cavity. Conforms to DIN24960, ISO3069, ANSI B73.1M standards. Inner diameter range: 35–170 mm. Applications include coal washery, mining, sewage treatment, paper making, metallurgy, power plants, and chemical engineering.
