About Mechanical seal type 3648
The Type 3648 is a high-performance, low-emission cartridge seal designed for maximum containment of hazardous fluids and light hydrocarbons. Its inboard seal is double-balanced to provide a positive seal with pressure from either direction. The outboard seal retains the barrier fluid using either an API Flush Plan 53 or 54. The Type 3648 seal can be utilized as a Type 2648 within specified limits (consult us for additional information).
