108 Single Face Submersible Pump Seal Framework The 108 single face submersible pump seal is a proven sealing solution widely used in submersible pumps for clean water, sewage and alkali water service. It combines a single face mechanical seal with a framework oil seal, forming a double protection barrier that keeps water out of the motor chamber even under submerged conditions. The multi-springs of this submersible pump seal do not contact the medium, which prevents blocking
