**Mechanical Seal IN0350.1120DUBVPGG: A Universal Cartridge Seal for Demanding Applications**

The IN0350.1120DUBVPGG is a high-performance, cartridge-type mechanical seal designed for reliable shaft sealing in pumps, mixers, and agitators. This model represents a standardized and widely compatible solution within the **catalog of mechanical seals**, specifically from the IN120DU series. Its design ensures easy installation and replacement, eliminating the need for complex setting measurements and reducing maintenance downtime.

**Technical Specifications and Construction**

This seal is engineered for a shaft diameter (d1) of 35 mm. The precise **dimensions of the mechanical seal** are critical for proper fit and function: the external diameter of the fixed part (d7) is 50 mm, while the outer diameter of the moving part (d3) is 49 mm. The overall seal length (L3) is 39 mm. The construction utilizes a robust material combination for durability across various media. The primary sealing face is composed of ceramic (moving part), which mates with a graphite fixed part, offering excellent wear resistance and thermal conductivity. The metal components are manufactured from AISI304 stainless steel, providing good corrosion resistance. The secondary sealing element is a nitrile rubber (NBR) bellows, suitable for a wide range of oils, water, and many chemicals. The driving force is provided by a cylindrical spring, ensuring consistent face loading.

**Cross-Reference and Interchangeability**

A key advantage of the IN0350.1120DUBVPGG is its direct equivalence to several major industry standards, facilitating sourcing and inventory simplification. It is a direct replacement for seals including M211 R7.035, Vulcan 7D, Aesseal T01 and T03D, Anga A3, and Roten U2. This broad compatibility makes it an ideal universal spare part for maintenance operations across diverse equipment fleets.

**Application and Benefits**

As a member of the 120D seal grade, this unit is designed for general industrial service. The cartridge design encapsulates all components—primary faces, spring, and secondary seals—into a single, pre-assembled unit. This design minimizes installation error, protects internal components from handling damage, and allows for quick seal changes. Its material selection balances cost-effectiveness with performance, making it suitable for applications involving water, light chemicals, coolants, and other non-aggressive fluids in temperatures and pressures within the limits of its NBR elastomer and material pairings.

When selecting from a **catalog of mechanical seals**, verifying the exact **dimensions of the mechanical seal** and shaft diameter is paramount for correct operation. The IN0350.1120DUBVPGG provides a reliable, interchangeable sealing solution that enhances equipment reliability and simplifies maintenance procedures.
