Separation Seal (Non-contacting Technology) IS609HTC

The IS609HTC is a high-temperature bellows assembly intended for those demanding applications where a dependable, high-strength, rotating seal is preferred. Typical applications for these seals include hydrocarbons, aromatic fractionation products, crude oil fractionation products and heat transfer fluids, as well as chemicals, caustics, some acids, aqueous solutions and lubricating liquids. This seal utilizes “HTC” technology with an all-Inconel, corrosion-resistant welded metal bellows for reliably sealing fluids in harsh high-temperature, corrosive environments and, at the same time, provides superior face stability at elevated temperatures. This all-Inconel seal is ideally suited for applications that contain organic acids (naphthenic acid), and sulfur compounds that attack most other alloys at high temperatures. The IS609HTC is utilized in our IS2609HTC and IS3609HTC API 682/ISO 21049 Type C Arrangement 2 and 3 cartridge seals.

Technical Description

Product Description IS609HTC

The ISHTC* high-temperature corrosion resistant welded metal bellows seal is a unique advanced technology for reliably sealing fluids in harsh high-temperature corrosive environments. The ISHTC also provides superior face stability at elevated temperatures.This all-Inconel ® seal eliminates the need for plating and is ideally suited for applications that contain organic acids, broadly referred to as naphthenic acid, and sulfur compounds that attack most other alloys at high-temperature.
Specially designed pressure-compensating seal faces and a thermally compliant primary ring adapter provide exceptional seal face stability that adapts to a wide range of temperature excursions inherent in high-temperature applications. Even if the application is not corrosive, the extra face stability provided by the seal can extend your MTBR in many other noncorrosive services. The API 682/ ISO 21049 qualified ISHTC seals are available in both stationary and rotating configurations, and single and dual seal arrangements.
IS604HTC – high-temperature corrosion resistant stationary bellows assembly capable of handling high shaft speed applications and high shaft-to-seal chamber misalignment. IS609HTC – high-temperature bellows assembly intended for those demanding applications where a dependable, high-strength, rotating seal is preferred
