Profile

 
Single end face cartridge type/Balanced/Independent of direction of rotation/ To API610. ApI682

The structural characteristics of SH328 series cartridge type mechanical seal are similar to SH318 series. SH328 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 structure. SH328 series seal is suitable for hazardous medium and medium wihich can easily solidify or vaporize. The SH328B double sealing face with bearing can effectively control the vibration and shaking of the equipment.
