single end, multi springs, balanced, independent direction of rotation, cartridge mechanical seal. The compensation components are supported on the sleeve so they rotate with the shaft. The elastomers protect the springs to avoid their direct contact with the sealed mediums so that the springs will not be jammed or corrupted. This lasts the life time of the mechanical seal. 
Scopes of Application: widely used in water treatment, power plants, metal processing, pharmacy, chemical fertilizer industry, and food production. Designed for water pumps, sewage pumps, chemical pumps, double suction pumps, paper pulp pumps and other rotary devices. This seal component is suitable for replacing gland packing.
