Single-end/unbalanced/arbitrary rotation This series of mechanical seals are multi-spring structure, small axial size, compact structure, reliable sealing, widely used in oil, water, organic solvents and other corrosive media. Specification: 14-100mm pressure: ≤ 1.7Mpa Temperature:-20 ℃ ~ 200 ℃ Linear speed: ≤ 25 m/s Axial channeling: ± 0.5mm Seal end face: graphite, silicon carbide, tungsten carbide, alumina Auxiliary seal: nitrile rubber, fluorine rubber, propylene rubber, PTFE |
1528 type mechanical seal is a derivative of 1527 type mechanical seal. Its installation size is the same as 1527 type, but 1528 type sealing ring has various forms, such as PTFE V-ring, PTFE O-ring, etc. It is more widely used. Sealing cavity pressure: ≤ 1.0MPa Sealing chamber temperature:-40 ℃ ~ 180 ℃ Line speed: ≤ 15m/sec Sealed medium: water, oil, weak acid weak alkali and other general corrosive chemical medium. |
Exterior single-end multi-spring PTFE bellows structure. Both dynamic and static rings are made of corrosion-resistant hard alloy or silicon carbide Sealing chamber pressure: 0.5Mpa Sealing chamber temperature:-10 ℃ ~ 150 ℃ Line speed: ≤ 3000r/min Medium: strong corrosive properties such as crystalline alkali salt solution. |
