**Mechanical Seal IN0160.4701.BVPGG: High-Performance Tandem Seal for Demanding Applications**

The IN0160.4701.BVPGG is a precision-engineered double (tandem) mechanical seal designed for reliable operation in pumps and rotating equipment handling challenging media. As part of the comprehensive **каталог торцевих ущільнень (catalog of mechanical seals)**, specifically the IN4701 series, this model offers enhanced sealing security by utilizing two sets of sealing faces arranged in series. This configuration is ideal for applications where preventing leakage to the atmosphere is critical, often used with a barrier fluid between the seals for increased safety and containment.

**Key Technical Specifications and Construction**

This seal is engineered for a shaft diameter (d1) of 16 mm. Its compact design features a total seal length (L3) of 36 mm. The fixed part, with an external diameter (d7) of 32 mm, is manufactured from high-wear-resistant ceramic, ensuring long-term stability and excellent surface finish for the primary sealing interface. The complementary moving part, with an outer diameter (d3) of 26.5 mm, utilizes graphite, a self-lubricating material known for its reliable performance across various fluid compatibilities. The metal components are constructed from AISI304 stainless steel, providing good corrosion resistance. The secondary elastomeric sealing elements are made from NBR (Nitrile rubber), a material chosen for its robust performance with oils, water, and many industrial fluids.

**Features and Operational Benefits**

The tandem design of the IN0160.4701.BVPGG provides a significant safety factor. In the event the primary seal faces experience wear or failure, the secondary seal acts as a backup, containing the process fluid and preventing uncontrolled leakage. This makes it a preferred choice for handling volatile, toxic, expensive, or environmentally hazardous liquids. The precise **розміри торцевого ущільнення (dimensions of the mechanical seal)** are critical for correct installation and optimal performance, ensuring a perfect fit within the seal chamber and on the shaft. The material combination of ceramic, graphite, AISI304, and NBR ensures durability, chemical compatibility, and reliable operation under standard industrial pressures and temperatures.

**Typical Applications**

This mechanical seal is suitable for a wide range of industrial pumps, including chemical process pumps, refinery applications, and equipment where enhanced sealing integrity is mandated. Its design is tailored for use in scenarios requiring a high degree of operational safety and environmental protection. When selecting from the **каталог торцевих ущільнень**, the IN0160.4701.BVPGG model stands out for applications demanding the reliability of a tandem configuration paired with a balanced selection of proven materials.
