The MSB is a simple, rotating, multi-spring, balanced ‘O’-ring mounted, pusher type seal for general-purpose application in chemical, petrochemical, oil & gas processing, water treatment and sewage plants, and pulp and paper mills, steel facility etc with ANSI chemical pumps.

Specific Features of MSB 

• The balance seal use at high pressure. 

• Simple and robust, balance it is a universal seal. 

• The stationary Insert part has a flexible mounted to prevent distortion.

• The multi-springs keep even pressure of seal face, so its stable. 

• The rotating part is automatically centered based on the axis.

• 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.
