**Mechanical Seal IN0280.112VPGG: High-Performance Single Cartridge Seal for Demanding Applications**

The IN0280.112VPGG is a precision-engineered mechanical face seal designed for reliable shaft sealing in pumps, mixers, and other rotary equipment. As part of the comprehensive **каталог торцевих ущільнень (catalog of mechanical seals)** series IN112, this model represents a robust solution for environments requiring durability and consistent performance. Its cartridge-type design with a clamping ring (с прижимным кольцом) ensures simplified installation and maintenance, reducing the risk of assembly errors and ensuring optimal seal alignment from the first start-up.

**Construction and Material Specifications**
This seal is built for longevity and resistance in challenging conditions. The primary sealing faces utilize silicon carbide (карбид кремния) for both the fixed and moving parts. This material pairing offers exceptional hardness, excellent wear resistance, and good thermal conductivity, making it suitable for handling abrasive media, slight crystallizations, and high-temperature operations. The metal structural components are manufactured from corrosion-resistant AISI304 stainless steel, providing strength and durability. The secondary elastomeric sealing element is made from NBR (Nitrile Butadiene Rubber), a versatile material known for its good resistance to oils, fuels, and a wide range of fluids.

**Precise Dimensional Integration**
Accurate **розміри торцевого ущільнення (mechanical seal dimensions)** are critical for proper fit and function. The IN0280.112VPGG is engineered for a nominal shaft diameter (d1) of 28 mm. The external diameter of the fixed part (d7) is 43 mm, while the outer diameter of the moving part (d3) measures 42 mm. The overall seal length (L3) is 43.5 mm. These precise dimensions ensure compatibility with standard housing bores and facilitate easy replacement, allowing for seamless integration into existing equipment without modification.

**Applications and Operational Benefits**
This mechanical seal is ideal for a broad spectrum of industrial applications, including chemical processing, water treatment, irrigation systems, and general industrial pumping. The single spring cartridge design with a clamping ring provides a balanced load on the sealing faces, promoting even wear and stable operation. The use of silicon carbide faces minimizes friction and heat generation, contributing to extended service intervals and reduced downtime. The seal's construction effectively prevents leakage, protects bearings from fluid ingress, and enhances overall equipment reliability and safety.

For engineers and maintenance specialists selecting from a **каталог торцевих ущільнень**, the IN0280.112VPGG stands out as a dependable, application-proven sealing solution. Its specific material composition and exacting dimensional standards make it a preferred choice for ensuring operational continuity in systems with a 28 mm shaft diameter under demanding service conditions.
