Product Introduction

DF-Type Floating Seal: As a core type of mechanical face seal, the DF-type floating seal is designed for rotating equipment operating under extremely harsh conditions. Featuring a diamond-shaped cross-section elastomer as the auxiliary sealing element, it provides a reliable sealing solution for heavy-duty equipment in construction, coal mining, and agricultural machinery. A diamond-shaped elastomer replaces the conventional O-ring. Made of high-quality rubber with excellent oil resistance, heat resistance, and aging resistance, it provides enhanced preload adjustment and displacement compensation. A pair of high-precision metal sealing rings (rotating and stationary) are manufactured through centrifugal casting and precision grinding to ensure close contact between the sealing faces. The elastomer, metal sealing rings, and housing form a stable assembly. The diamond-shaped elastomer centers the metal rings within the housing while allowing radial movement to accommodate minor vibration and eccentricity during operation. https://www.hqjxco.com/?list_22/84.html
