API 682 Type C, Arrangement 2 or 3 – Type VD10 17D is a high-temperature, corrosion-resistant double cartridge metal bellows seal with a flow guide and integrated pumping ring, independent of shaft rotation direction. The pressure-balanced metal bellows and Inconel alloy material selection make this type superior, designed specifically for corrosive applications involving organic acids or sulfur compounds that attack most other materials at high temperatures. It is designed to seal fluids in a wide range of refinery applications, including hydrocarbons, crude oil products, aromatic fractionation products, and chemicals.
