Slurry & FGD Seals

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 B1M standards. Inner diameter range: 35–170 mm. Applications include coal washery, mining, sewage treatment, paper making, metallurgy, power plants, and chemical engineering.

Single end, multiple springs, balanced cartridge mechanical seal with spring protector, independent direction of rotation and static compensation structure. Springs housed in stationary component cartridge, isolated from medium to prevent jamming from high viscosity and crystallization. Compensation components support the sleeve for extended lifetime. Easy installation without disassembling the seal cavity. Conforms to DIN24960, ISO3069, ANSI B1M standards. Inner diameter range: 35–170 mm.

Single end, multiple springs, balanced cartridge mechanical seal with spring protector and independent direction of rotation. Supports external seal flush or noflush operation. Springs isolated from medium to prevent jamming. Stationary and rotary rings palletized with Lstyle pad for higher flexibility under temperature changes. Unlike AS ZGJ, this seal works with devices that do not have or need a cooling system. Conforms to DIN24960, ISO3069, ANSI B1M, JB/T 123912015 standards. Inner diameter range: 35–170 mm.

Single end, multiple springs, unbalanced cartridge mechanical seal with internal bearing kit sealed by 2 pieces of framework oil seals. Independent direction of rotation. Conforms to API682 standard. Inner diameter: 25 mm. Suitable for limewater and aqueous solutions containing chloride ions.

Single end, multiple springs, balanced cartridge mechanical seal with spring protector and independent direction of rotation. Springs isolated from medium to prevent jamming from high viscosity and crystallization. Compensation components support the sleeve for extended component lifetime. Easy installation without disassembling the seal cavity. Conforms to DIN24960, ISO3069, ANSI B1M standards. Inner diameter range: 35–170 mm. Applications include coal washery, mining, sewage treatment, paper making, metallurgy, power plants, and chemical engineering.

Double end, multiple springs, unbalanced mechanical seal with independent rotary direction and lug transmission. Small axial dimensions with balanced seal face load. Preassembled compensation components for easy installation. Requires circulated barrier liquid (1–2 MPa above medium pressure) to prevent contamination. Suitable for crystallized mediums with particles. Conforms to DIN24960, GB6556, ISO3069 standards. Inner diameter range: 25–160 mm.

Single end, multiple springs, balanced cartridge mechanical seal with independent rotary direction, still structure and clamp transmission. Springs protected by elastomers from medium to prevent jamming. Sleeve supported by elastomers on shaft with no axial movement or shaft damage. Guide sleeve structure for high cooling efficiency. Requires sealant at 01–1 MPa for natural flow (external flush mechanical seal). Conforms to ISO3069, DIN24960, GB6556 standards. Inner diameter range: 35–250 mm.

Single end, single spring, balanced mechanical seal with spring assembled outside housing and independent rotary direction. Still structure design allows easy adjustment, big axial movements, and easy inspection. Spring isolated from medium to prevent jamming — suitable for mediums with particles. Rotary ring locked on sleeve with simple, reliable transmission. No flush cooling needed (dry running mechanical seal). Specifically customized design. Inner diameter range: 30–120 mm.
