Series 50
Reverse Balance Seal
Type: 50
Series 50 is multiple spring externally mounted balanced seal with ‘O’ ring as secondary sealing member. The unique feature of this type of seal is that, it eliminates the shaft step or sleeves for balancing. Various seal face materials and elastomers can be offered for wide service application. This seal can also be used for corrosive services as the metallic components i.e. Retainer, Spring, Thrust Ring etc do not come in contact with liquid to be sealed. The compact design eliminates the requirement of extra radial & axial space for its installation.
