Profile

Single end face cartridge type / Balanced / Independent of direc-tion of rotation/ To API610. API682

The structural characteristics of JG328 series cartridge type mechanical seal are similar to JG318 series. JG328 series is designed with flushing opening, double sealing face. It is suitable for working circumstances where the system pressure quickly increases or decreases due to the back-to-back strulture. JG328 series seal is suitable for hazardous medium and medium which can easily solidify or vaporize. The JG328B double sealing face with bearing can effectively control the vibration and shaking of the equipment.
