  • System and method for protecting a submergible motor from corrosive agents in a subterranean environment
    Patent number: 6268672
    Abstract: A motor protector for use in protecting an electric motor in a subterranean environment. The motor protector utilizes a dual, flexible bladder system. One of the expandable bladders provides for the expansion and contraction of motor oil. The other expandable bladder contains a supply of neutralizing solution. The bladder filled with neutralizing solution cooperates with the bladder filled with motor oil to maintain the expandable bladder bathed in neutralizing solution. This prevents migration of corrosive agents into the motor oil.
