Mechanical seal IN0200.1120ABVPGG

The mechanical seal IN0200.1120ABVPGG is a precision-engineered component from the IN120A series, designed for reliable shaft sealing in a wide range of industrial rotary equipment. This model represents a standardized solution within the comprehensive catalog of mechanical seals, offering consistent performance and interchangeability. Its construction is defined by a balanced selection of materials and precise dimensions, ensuring effective operation in pumps, mixers, and agitators handling water, light oils, and various non-aggressive fluids.

Key to its performance are the specific material pairings and dimensional accuracy. The primary sealing faces consist of a stationary part manufactured from graphite and a rotating face made of high-grade ceramic, providing excellent wear resistance and stable friction characteristics. The metal components are constructed from corrosion-resistant AISI304 stainless steel, while the secondary elastomeric seal is made from NBR (Nitrile Butadiene Rubber), suitable for a broad temperature range and compatible with many fluids. The seal utilizes a cylindrical spring design for uniform face loading, contributing to consistent sealing pressure and compensation for minor axial shaft movements.

Critical installation and compatibility dimensions are central to its specification. The seal is engineered for a nominal shaft diameter (d1) of 20 mm. The external diameter of the fixed part (d7) is 30.9 mm, and the outer diameter of the moving part (d3) is 31 mm, with an overall seal length (L3) of 25 mm. These precise dimensions of the mechanical seal are essential for correct housing fitment and operational reliability. Engineers and maintenance specialists consulting the catalog of mechanical seals will find these parameters crucial for selecting the correct replacement or specifying a new installation.

As a part of the 120A seal grade family, the IN0200.1120ABVPGG is characterized by its robust yet economical design, making it a versatile choice for general industrial applications. Its standardized design facilitates easy procurement and replacement, minimizing equipment downtime. When selecting a seal based on the catalog of mechanical seals, verifying the exact dimensions of the mechanical seal against the equipment's housing and shaft specifications is a critical step to ensure optimal performance and service life.
