MG13 Rubber Bellows Seal 10~120mm Single Mechanical Seal for 1.2Mpa Pressure and -20°C to +120°C Temperature Range

The MG13 Rubber Bellows Seal is a single-acting mechanical seal utilizing an integral molded rubber bellows. This design functions as both the secondary seal and the axial spring mechanism, eliminating the need for separate fasteners. It is engineered for general service applications handling water, oils, and mildly corrosive fluids. Standard operating parameters include a maximum pressure of 1.2 MPa and a temperature range from -20°C to 120°C. Common construction materials include silicon carbide, tungsten carbide, or carbon for the primary sealing faces, with elastomer options such as NBR, EPDM, or FKM for the bellows.

Q1: What are the key design features of the MG13 Rubber Bellows Seal?

A1: The MG13 features an integral molded rubber bellows that serves as both the secondary seal and the axial spring mechanism. This single-spring, non-balanced design eliminates the need for separate fasteners or drive bands.

Q2: In which applications is the MG13 Rubber Bellows Seal commonly used?

A2: This seal is commonly applied in general service pumps handling water, coolants, mild chemicals, and non-abrasive fluids. Typical applications include industrial cooling systems, HVAC circulation pumps, and various transfer pumps in chemical processing.

Q3: What are the standard operating parameters for the MG13 Rubber Bellows Seal?

A3: The standard MG13 seal is rated for maximum operating conditions of 1.2 MPa pressure, temperatures from -20°C to 120°C, and shaft speeds up to 10-12 m/s surface velocity.

Q4: What materials are typically used for the construction of the MG13 Rubber Bellows Seal?

A4: Standard construction includes silicon carbide, tungsten carbide, or carbon primary sealing faces. The bellows material is typically NBR, EPDM, or FKM elastomer, with stainless steel spring components.

Q5: How does the MG13 design perform in applications with potential solids in the fluid?

A5: The rubber bellows design provides flexibility that helps prevent clogging from particulate accumulation. When specified with hard face materials like silicon carbide, it offers reliable performance in fluids with moderate solids content.

Q6: Can the MG13 Rubber Bellows Seal be customized for specific service conditions?

A6: Yes, the seal can be configured with alternative face material combinations and specialized elastomer compounds to accommodate specific chemical compatibility requirements or operating temperature ranges.
