The SMHD is an unbalanced, multi-spring, dual seal, specially developed for submersible pumps, water pump and water treatment facilities.

Specific Features of SMHD
• Simple and robust, it is a universal seal.
• The rotating part is automatically centered based on the axis, and a number of springs and pins distribute the load.
• The simple, rugged, and open rotating part creates turbulent flow in the fluid or buffer fluid used to resist corrosive, erosive, and viscous fluids, and removes frictional heat generated on the seal face.

Operating Capabilities
