Product Introduction

Coated Sand DO-Type Floating Seal: Manufactured using the coated sand casting process, the DO-type floating seal is a light-duty, non-contact mechanical seal designed for demanding operating conditions. It consists mainly of two cone-shaped metal sealing rings and two O-rings, and is widely used in construction and mining machinery. Metal Sealing Rings: Made of high-alloy cast iron with a tapered cross-section. The sealing surfaces are precision-ground for excellent wear and impact resistance. O-Rings: Commonly made of NBR or HNBR, providing axial preload and compensation for installation tolerances and thermal expansion. Assembly: The two metal rings are installed on the stationary and rotating sides respectively. The O-rings are compressed between the metal rings and housing, generating the required sealing preload. Excellent Contamination Resistance: Effectively prevents dust, mud, water, and abrasive particles from entering, making it suitable for harsh mining and construction environments.
