- Basic Features - Structure: Single End - Pressure: Medium Pressure Mechanical Seals - Speed: Medium Speed Mechanical Seal - Temperature: General Temperature Mechanical Seal - Performance: Corrosion - Standard: Non-standard - Model NO.: SD-25 - Balance: Unbalanced - Specification: Inner Diameter: 25 mm Product Detailed Description SD-25 Single Spring PTFE Bellow Mechanical Seal for Acid Pumps Structural Features: single end, single spring with PTFE elastomer bellow protection, unbalanced, shift transmission. The metal parts do not have direct contact with the sealed mediums so that the seal would have a long life-time. Inboard installation, which can stand higher medium pressure. The shift transmission is reliable and the whole component is easy to install with a wide scope of applications. Industrial Standards: Non-standard Scopes of Application: widely used in chemical engineering, oil painting, electroplating and acid pickling. This mechanical seal was designed for mainly acid pumps and similar types of rotary devices. Operation Parameters: Pressure: 0.6 MPa or less Temperature: 0 ºC to 80 ºC Linear Speed: 10 m/s or less Materials: Rotary Ring Face: Carbon/SiC Stationary Ring Face: SiC Elastomers: FKM/PTFE/FFKM Springs: SS304/SS316/SS316L Metal Parts: SS304/SS316/SS316L Mediums: strong acid, strong oxidant, reductant, and organic solvents; sulfuric acid, nitric acid, hydrochloric acid, magnesium chloride, electroplate liquid and etc. Customization: Changes of materials for getting other operating parameters are possible.
