Abstract
The high pressure seal is for use with submersible electric pumps employed in water treatment apparatus and with any other electrical device used under similar conditions. The high pressure seal provides a device for closing an opening in a wall of a housing containing high pressure water and for sealing around wires extending through the opening. The high pressure seal includes a hollow fitting for engaging within the opening in the housing, an insert having a number of bores extending through the insert for receiving the wires, and seal enhancing means including raised protrusions arranged internal to and annularly around each bore for sealing around the wires. The high pressure seal may alternatively include a solid fitting for engaging within the opening in the housing, a number of bores extending through the fitting for receiving the wires, and a ring shaped insert arranged in an annular groove arranged around each bore for sealing around the wires.
